    DESCRIPTION
    Air conditioner Background of the invention Field of the invention
    The present invention relates to an air conditioner, and more specifically to an indoor unit. Background
    There is a conventional air conditioner that includes an indoor unit with dimensions 360 mm high and 150 mm deep, where a cross-flow fan has a diameter of 86 mm and the number of stages of an indoor heat exchanger is 14 (For example, reference is made to the Japanese Examined Patent Publication No. 7-30926 (second paragraph, and Figure 1)).
    Description of the related technique
    At present, efforts have been made at the social end to save energy in air conditioners, whose energy consumption is supposed to be the highest among domestic appliances, in order to reduce global warming. Especially, a list of components of a separate type air conditioner used by connecting the indoor unit that is installed hanging from the wall inside a room and an outdoor unit that includes a compressor and the external heat exchanger, etc. by means of a cooling pipe, it has the highest consumption of all air conditioners, and stricter regulations have been established for energy savings in separate air conditioners than in the other types of conditioner categories according to the Energy Conservation Law (Law that refers to the rational use of energy).
    In this way, as efforts are made to save energy, heat exchangers or the like have increased in size and capacity to improve the efficiency of the air conditioner. For this reason, air conditioners have increased their dimensions and weight. Specifically, air conditioners having a configuration in which an indoor wall unit and an outdoor unit are connected by means of a cooling pipe is a main flow of the air conditioner for domestic use, whose regulation value, according to the Energy Conservation Law (Law that refers to the rational use of energy) is high in air conditioners. Air conditioners that operate with high energy savings tend to increase in size, and there is a tendency to increase the exterior dimensions of the outdoor unit, and the horizontal width and vertical width of the indoor unit.
    One of the reasons for the larger sizes of both the indoor unit and the outdoor unit is that the conventional energy saving regulation (the standard for fiscal years 2004 and 2007) has been an average value of COP (average cooling COP / heating, COP is the coefficient of calorific efficiency) in values below the condition of the contribution ratio to heating and cooling. For the average cooling / heating COP, increasing the size of both the indoor unit and the outdoor unit has the same energy saving effect, so that both the indoor unit and the outdoor unit have increased in size. However, as of fiscal year 2010, the regulation to save energy was changed to the evaluation of the annual energy consumption efficiency (according to the APF standard, APF is the Annual Performance Factor), which adapts better to the conditions current. Therefore, the configuration of an indoor unit and an outdoor unit more suitable for improving APF is reconsidered.
    Meanwhile, housing conditions have diversified in recent years. For example, in a room built with the Japanese style, a module dimension is usually used between columns of a length of 3 shaku (approximately 90.9 cm, “shaku” is one of the units of the old Japanese measurement system, or Shaku-Kan system), a column of 3.5 sun (a column with a dimension of approximately 106.75 mm, where "sun" is one of the units of the Shaku-Kan system), so that the horizontal width of the space of the wall surface on which the indoor unit of an air conditioner can be installed is approximately 800 mm. In addition, to achieve a sophisticated interior in a room, for example, there are more and more cases in which the windows are enlarged, and the vertical width of the space left over the windows to install the indoor unit of an air conditioner is approximately 295 mm, so that there is a tendency to reduce the size of the installation space available for the indoor unit of an air conditioner. In addition, the size of the rooms is progressively increasing, so that the living room and dining room or kitchen are combined, and the surface of the walls of the rooms is reduced, so that the installation area for an air conditioner decreases of wall.
    As stated above, there is an increase in the need for high-capacity air conditioners (improved performance) due to the increasing size of the rooms, and there is also a progressive growth in the size of the unit, due to the need for greater performance to save energy and greater efficiency of air conditioners. At the same time, from the standpoint of housing conditions, problems have increased in such a way that it is impossible to install the indoor unit of the

    Description of the preferred embodiment
    Realization 1.
    The first embodiment according to the present invention is explained below with reference to Figures 1 to 7. Figure 1 is a diagram of the cooling circuit of an air conditioner according to the present invention. A cooling cycle is formed in the diagram by sequential connection of a compressor 1, a four-way valve 2, an external heat exchanger 3, an expansion mechanism 4 (electronically controlled expansion valve) and an internal heat exchanger 5. In addition, an outside blower 6 (fan of

    drive) on an air flow path where the external heat exchanger is arranged 3. An internal blower 7 (cross flow fan) is installed on an air flow path where the internal heat exchanger 5 is arranged.
    During a refrigeration operation, a compressed refrigerant at high temperature and pressure blows from the compressor 1 and flows into the exterior heat exchanger 3 via the four-way valve 2. In the external heat exchanger 3, the external air undergoes a thermal exchange while the outside air is passed between fins and tubes (heat transfer tubes) inside the external heat exchanger 3 by the external blower 6 installed in the air flow path of the external heat exchanger 3, while the refrigerant is cooled to a high pressure liquid state, and the external heat exchanger 3 acts as a condenser. Next, the refrigerant passes through the expansion mechanism 4 and its pressure is reduced until it becomes a two-phase low pressure refrigerant, and then flows into the interior of the internal heat exchanger 5. In the internal heat exchanger 5, it is made pass the indoor air between fins and tubes (heat transfer tubes) of the inner heat exchanger 5 when the inner blower 7 is operated in the air flow path where the inner heat exchanger 5 is installed and exchanges heat with the refrigerant. This causes the air blown inside an interior space to be cooled, while the refrigerant receives heat from the air and evaporates to a gas state (the interior heat exchanger 5 acts as an evaporator). Next, the refrigerant returns to compressor 1 and circulates so that the air in the interior space is conditioned. In addition, in a case of heating operation, the action of the four-way valve 2 is reversed, so that the refrigerant flows in a direction opposite to the previous one during the refrigeration cycle. The internal heat exchanger 5 acts as a condenser and the external heat exchanger 3 acts as an evaporator to heat the indoor air.
    Figure 2 is a cross-sectional view of the indoor unit of an air conditioner according to the first embodiment of the present invention. Figure 3 is a front view of the air conditioner according to the first embodiment of the present invention. In Figure 2, the indoor heat exchanger 5 housed inside the indoor unit cools and heats the sucked air through a suction groove 17, which is composed of heat transfer tubes that penetrate through fins of radiation staggered at certain intervals. The internal heat exchanger 5 forms a part of a refrigeration cycle that includes the compressor and the expansion valve, and a refrigerant circulating through the refrigeration cycle flows into the heat transfer tubes and exchanges heat with the air at Be cooled and heated. A transverse flow fan 7 sends air to an exhaust opening 18 through an air flow path 16 from a suction groove 17. A vertical air flow addressing blade controls a direction of the flow of the air blown from the exhaust opening 18 in an upward and downward direction. A filter 13 captures the dust contained in the air sucked from the suction groove 17. A filter cleaning mechanism 14 removes the dust adhering to the filter 13. A drain pan 15 includes a nozzle 20 that forms an upper wall of the Air path from the adjacent flow to the exhaust opening 18, to recover the condensation of the dew created in the internal heat exchanger 5 at a time of the cooling or dehumidification operation. The air flow path 16 goes from the suction slot 17 to the exhaust opening 18. An exhaust opening 18 releases the air sucked from the suction slot 17 by the cross flow fan 7 into a room through the air flow path 16. A display unit 12 shows an operating state of the indoor unit. A receiving unit 19 receives a remote control signal to exercise the remote control.
    In addition, the installation interval (separation of the stages) of the centers of the heat transmission tubes, which constitute the indoor heat exchanger 5, in a vertical direction is 15 to 22 mm and the indoor unit has a height H 295 mm or less. In the interior heat exchanger 5, the heat exchanger on the front side 5a has a V-shape folded approximately towards the center in a double or integral partition, and the mountable number (the number of stages) of transfer tubes of Heat of the heat exchanger of the front side 5a in a vertical direction is about 12 tubes, while the mountable number of heat transfer tubes of a heat exchanger of the rear side 5b in a vertical direction is about 6 tubes . That is, the indoor heat exchanger 5 has a capacity of not less than 16 stages together. In addition, the auxiliary heat exchangers 5c are each constituted by a row arranged on one side of the stream upstream of the air flow of the internal heat exchanger 5. The auxiliary heat exchangers 5c are arranged on the upstream sides of each of the lower sides of the heat exchanger on the rear side 5b and the heat exchanger on the front side 5a.
    In addition, a center of rotation of the transverse flow fan 7 is located on a lower side relative to a center of the height H of the indoor unit, but located above a third of the height H from the lower end, so that a space is provided on an upper side of the interior of the indoor unit, on which the heat exchanger on the rear side 5b can be mounted. Furthermore, by a position of the center of rotation of the cross-flow fan 7 and a shape and position of the internal heat exchanger 5, a diameter of the fan of the cross-flow fan 6 can be equal to or greater than 100 mm, which allows Reduce noise and get high efficiency.
    In Figure 2, the indoor air suction slot 17 inside the indoor unit is arranged in an upper section of the indoor unit facing the upper side of the heat exchanger on the front side 5a and the heat exchanger on the rear side 5b and is covered by a grid 9 through which the indoor air passes. Dice

    that the suction groove 17 is formed so that it occupies most of the upper section of the indoor unit, having sufficient suction area, a design surface of the front side of the indoor unit does not include an air suction groove inside.
    In addition, the filter 13 is arranged in an air flow path between the panel 9 where the suction slot 17 and the interior heat exchanger 5 are arranged, which has a function of capturing the dust flowing in the air from the slot of suction 17 before the powder enters the internal heat exchanger 5. The filter cleaning mechanism 14 is composed of a movable device for moving the filter 13, a pressurizing unit 14c for driving the filter 13 against a brush 14a, the brush 14a to collect the dust that adheres to the filter 13 and a dust collection container 14b to store the collected dust. Since the air conditioner periodically removes the dust that adheres to the filter 13, it is possible to keep the internal heat exchanger 5 or the transverse flow fan 7, etc., arranged inside the air flow path of the air indoor unit and also prevent dust from accumulating in the filter. Therefore, it is possible to prevent the reduction of air volume and maintain efficiency for an initial period. Since the antibacterial and antifungal treatment is applied to the dust collection vessel 14b, it is possible to prevent the spread of bacteria and mold to the collected dust.
    Furthermore, since the filter cleaning mechanism 14 is located diagonally with respect to the upper front part of the heat exchanger of the V-shaped front side 5a with a predetermined interval, and a space is provided between the filter cleaning mechanism 14 and the heat exchanger on the front side 5a, the air passing through the filter 13 flows to a lower portion of the heat exchanger on the front side 5a without being obstructed by the cleaning mechanism of the filter 14. In this way, the exchange of Heat can be performed efficiently and you can get high performance that saves energy.
    In addition, part or all of the filter cleaning mechanism 14 is not located between an upper end of the heat exchanger on the front side 5a and an upper end of the heat exchanger on the rear side 5b, and the suction groove 17, so that The filter cleaning mechanism 14 does not affect the height H of the indoor unit. In addition, the indoor heat exchanger 5 can be efficiently installed inside the indoor unit 1 with a height restriction. In this way, high performance can be obtained that saves energy.
    In addition, the filter cleaning mechanism 14 is located in front of the heat exchanger on the front side 5a and a part or all of the filter cleaning mechanism 14 is not arranged between one end of the internal heat exchanger 5 in a horizontal direction and a lateral surface of the indoor unit, so that the filter cleaning mechanism 14 does not cause the width L of the indoor unit to increase or be horizontally wide. In addition, the indoor heat exchanger 5 can be efficiently installed inside the indoor unit 1 with a width restriction. In this way, high performance can be obtained that saves energy.
    In addition, even when the filter cleaning mechanism 14 is not installed, it is possible to keep the interior of the indoor unit clean and also prevent dust from accumulating in the filter if users clean the filter 13 periodically. Thus, efficiency can be maintained for an initial period. In addition, by installing a dust collection device to collect dust often contained in the room air and a deodorization device to remove or dissolve the smelly component of the room air, it is possible to increase comfort in space inside.
    In addition, the grill 10 which is arranged in a position facing the heat exchanger of the front side 5a on a front side of the indoor unit so that it can be opened and closed, or detachably, does not include a suction opening in its front side, as shown in Figure 3, so that it is possible to provide a sophisticated interior. Since the suction groove 17 is concentrated in the upper portion of the indoor unit, it is possible to reduce the size of the filter 13, which allows an economical configuration. In addition, since the height of the indoor unit is up to 295 mm in Figure 2, and the width of the indoor unit is up to 800 mm in Figure 3, there is also an effect by which the installable area is increased over the interior wall surfaces without being affected by the aforementioned installation limitations of the housing conditions, such as the limitation of the installation space with respect to the width size due to the use of a column of 3.5 soles ( a column with a dimension of about 106.75 mm, where the "sun" is one of the units of the old Japanese measurement system, or Shaku-Kan system) in a Japanese-style room built according to the intercolumn module dimension of a length of 3 shaku (about 90.9 cm, where "shaku" is one of the units of the Shaku-Kan system), and the size of the height due to the increase in the size of the windows.
    Figure 4 is a graph showing the relationship between the number of stages of the internal heat exchanger and the total material used in the internal heat exchanger and the external heat exchanger (sum of copper and aluminum) with the same utilization ratio of standard values according to the Energy Conservation Law, in which the vertical axis shows the use of the material (unit: kg) and the horizontal axis shows the number of stages of the indoor heat exchanger. The graph has been calculated as the heat exchange capacity varies depending on the changes in the number of stages of the indoor heat exchanger assuming that a unit size (width) of the indoor unit is constant. According to the standard of the Energy Conservation Law of the fiscal years 2004 and 2007, which is an average value of the nominal cooling COP and the nominal heating COP, although the number of stages of the indoor heat exchanger, the use of the material remains approximately constant, as described in the

    Figure 4 using a continuous line, since it is possible to obtain the same performance to save energy by increasing the size of the external heat exchanger with a reduction in the size of the internal heat exchanger even if the number of stages of the internal heat exchanger decreases. On the other hand, according to the standard of the Energy Conservation Law from the fiscal year 2010, which is the APF (Annual Performance Factor, or annual efficiency of energy consumption) the contribution of the Improving the efficiency of the indoor heat exchanger to improving the efficiency of the APF is large, so that it is necessary to increase the size of the outdoor heat exchanger the same or more that the size of the indoor heat exchanger has been reduced. Therefore, the use of the material can be further reduced by increasing the number of stages of the internal heat exchanger instead of increasing the size of the external heat exchanger, as shown in Figure 4 by the dashed line.
    In addition, in an air conditioner that follows a refrigeration cycle, to improve the cooling performance, the use of material may be less by increasing a size of an outdoor unit instead of increasing a size of an indoor unit. In the same way, to improve the heating performance, the use of material may be less by increasing the size of the indoor unit than if the size of the outdoor unit is increased. In the air conditioner that has such characteristics, according to the Energy Conservation Law of the fiscal years 2004 and 2007, the cooling and heating contribution ratio to the improvement of the average cooling / heating COP it is 1 to 1, while according to the Energy Conservation Law as of fiscal year 2010, the ratio of cooling and heating contribution to the improvement of APF is 1 to 3. Thus , according to the APF standard, heating improvement is more efficient, and the use of material can be further reduced by increasing the size of the indoor unit instead of the size of the outdoor unit. In addition, the use of material can be further reduced by using alminun or alminun alloy for the fins and / or heat transfer tubes of the heat exchanger.
    Figure 5 shows the diameter of the fan and the volume of air with the same noise level when the number of stages of the indoor heat exchanger 5 is 16. The vertical axis shows the volume of air (unit: m3 / min) to be driven and the horizontal axis of ours a diameter (unit: mm) of a cross flow fan, with the values shown by a continuous line. The larger the diameter of the fan, the greater the size and the number of blades. Therefore, it is also possible to increase the volume of air, which leads to an improvement in the heat exchange capacity. Therefore, it is shown that the APF improves as the diameter of the fan increases. In this case, as the diameter of the fan increases, the volume of air to be sent can be increased, which results in an improvement in APF. However, if the height of the indoor unit H is limited to 295 mm or less, the smaller gap between the heat exchanger and the cross flow fan becomes small and an extraordinary noise (turning noise) appears when the diameter of the fan is equal to or greater than 115 mm. Therefore, the appropriate size of the fan diameter is 110 mm to 115 mm.
    In a conventional air conditioner that includes an indoor unit with a maximum width of 800 mm or less, and a maximum height of 295 mm or less, a method is used such that an air conditioner with an indoor unit of dimensions larger than the aforementioned indoor unit is applied a similarity reduction to obtain an indoor unit with a cross section of 800 mm or less in width and 295 mm or less in height, and the conditioner is configured to include a cross flow fan with a diameter of 99 mm or less, and an indoor heat exchanger that has 15 stages or less to reduce the size of the indoor unit, and performance to save deteriorated energy (standard COP medium cooling / heating) is compensated by the outdoor unit, so that the use of material does not increase. However, since the standard changed to the APF standard according to the Energy Conservation Law as of fiscal year 2010, by configuring an indoor unit with a maximum width equal to or less than 800 mm and a maximum height equal to or less than 295 mm to include a cross-flow fan with a diameter of 100 mm or greater and an internal heat exchanger with 16 stages or more, it is possible to reduce the use of material while achieving High efficiency and helps reduce the burden on the environment.
    Figure 6 is a cross-sectional view of an indoor unit for another air conditioner according to the first embodiment of the present invention. The internal heat exchanger 5 is configured to be an integral heat exchanger where a front surface on an air inlet side and a rear surface on an air outlet side form a continuous surface from the upper end to the lower end , so that it is possible to freely establish a shape of the indoor heat exchanger 5 according to the shape of an indoor air flow path. Therefore, the heat exchanger can be packaged in a denser state and its size can be reduced with high efficiency. In addition, it is possible to further reduce the load on the environment without using additional materials for the indoor air flow path.
    In addition, Figure 7 is a view of the right side of the air conditioner according to the first embodiment of the present invention. In recent years, due to the increase in recycling of recyclable plastic and, in addition, due to the technological improvement in the removal of impurities from the collected plastic, reprocessed plastic has been applied not only to a cross-flow fan that users cannot see directly, but also to design parts. For example, as shown in Figure 7, a further reduction of the load on the environment is sought by the use of reprocessed plastic in a main body 8 in which the internal heat exchanger 5 and a blower device, etc. , are fixed and secured; in panel 9 which includes a side face of an outer shell

    and a suction opening; in the grid 10 as a design surface on the front side, which is arranged in a way that can be opened and closed or in a removable manner; in a design part that forms an outer envelope of the vertical air flow direction blade (not shown); and in the cross flow fan.
    In Figure 2 and Figure 3, the suction groove 17 is explained so that it is formed only on the upper surface of the indoor unit. However, it is not limited to this configuration, and the suction groove 17 may only be formed on the front side of the indoor unit. At the same time, in a configuration where the suction groove 17 is formed on both the upper surface and the front surface as well, the same effect on transmitted from the server can be obtained.
    The air conditioner according to the present invention, which includes the indoor unit of the type hung on the wall, whose air conditioner is formed by connecting the inverter driven compressor whose rotation can be controlled, the four-way valve, the heat exchanger indoor heat, the decompression device and the outdoor heat exchanger, and which is capable of operating the refrigeration cycle and the heating cycle by switching the four-way valve, includes:
    the indoor unit that includes the box having the suction opening, either on the upper surface or on the front surface, or on the upper surface and on the front surface, and the exhaust opening on the lower surface and the fan of transverse flow that sends the internal air sucked from the suction opening inside the box to the exhaust opening through the interior heat exchanger,
    the indoor unit having a shape whose size is up to 800 mm wide, and up to 295 mm high, that the diameter of the cross flow fan is not less than 100 mm but not more than 115 mm, and that the number of Interior heat exchanger stages not less than 16.
    Therefore, the air conditioner has an effect of achieving high energy saving performance within a size range of the indoor unit taking into account an installation space of the air conditioner, and also an effect of reducing the load on the environment by reducing the use of material.
    Having thus described several particular embodiments of the present invention, various alterations, modifications and improvements will readily occur to those skilled in the art. Therefore, the above description is by way of example only, and is not intended to be limiting. The present invention is limited only as defined in the following claims and their equivalents.
