    Defrosting device (1) comprising: an energy well (2), a heat pump (3) which is adapted to absorb and transfer heat from the energy well (2) by means of a line from the energy well to the heat pump (3) for transporting antifreeze liquid, a heat outlet ( 4) connected to a heat pump (3) which can optionally be in a connected or disconnected position, defrosting loops (5) for defrosting surrounding the defrosting loops (5), in which the frost-proof liquid is edge transported, which defrosting loops (5) can optionally be connected to and disconnected from the line from the energy well to the heat pump (3), a single heat exchanger (7) connected to the heat outlet (4) adapted to selectively transfer heat to the defrost loops (5) by means of the heat outlet (4), a control system (6) adapted to control the defrost device (1) ) so that low-temperature heat from the energy well (2) or high-temperature heat from the heat pump (3) and the heat outlet (4) can be selectively used to warm, thaw or maintain warm ground surrounding the defrost loops (5).

    专利说明:

    The combination of using both LT (low-temperature heat from the Brine circuit) and high-temperature from the heat pump and making this possible with ordinary property heat pumps is used by the invention.
    This has given an invention which in a cheap way makes it possible to build energy-efficient thawing plants.
    The invention is particularly well suited where the need for thawing is greatest in connection with mild weather where ice and mud occur on driveways / slopes. In good time, "free" maintenance heat can be added and heated - or if the brine solution is warm enough. Thaw the substrate. Thereafter, heat pump energy can be supplied for rapid further heating / melting. When this has happened, you can again circulate brine solution in the loops and resist further cooling. The speed of the whole process is improved when insulation is laid under the loops. However, there needs to be some depth when it is outdoors to reduce the risk of frost during rapid weather changes.
    Examples of advantages: Suitable for villas etc. - where you are energy / cost conscious.
    The invention is suitable for automatic control / connection to weather data.
    Designations in sketches Alt 1 and Alt 2 VU = Heat outlet, from the pump via a high-power outlet, eg a so-called polar heat outlet instead of directly from the radiator circuit which has a low temperature in warmer weather and then finds it difficult to leave the necessary effect for thawing.
    VP = Heat pump E = Energy well (ex borehole) T = Defrost loops Designations and settings in Alt 1 Case 1 Case 2 Case 3 P = Circulation pump (with non-return valve - for case 2) OFF OFF ON A, B = Closing valves Closed Open Closed C = Closing valve Open Closed Open Pv = heat outlet Off Off ON

    1. Alt. 1 4 sketches where the first sketch describes the entire plant and table how valves etc. should be set in the 3 different work cases that three of the sketches describe. Case 1 = No thawing function is used. The rock heat pump can work. Case 2 = Only "thawing" with brine solution. The rock heat pump can work. Case 2.1 - Function when the heat pump is operating (circulation thereby) or the circulation pump in the heat pump is forcibly controlled (when the heat pump is not working but its circulation pump must work to provide circulation through the defrost coils) Case 2.2 - Example of function when the heat pump is designed it is rejected. A bypass line with its own circulation pump is available for this case. Case 3 = Defrost with heat pump energy. The rock heat pump works. Alt. 2 3 sketches where all the sketches describe the entire plant and the flows are drawn and thereby show how the valves should work in the 3 different work cases. Case 1 = No thawing function is used. The rock heat pump can work. Case 2 = Only "thawing" with brine solution. The rock heat pump can work. Case 2.1 - Function when the heat pump is working (circulation thereby) or the circulation pump in the heat pump is forcibly controlled (when the heat pump is not working but its circulation pump must work to provide circulation through the thawing loops) Case

    2.2 - Example of function when the heat pump is designed so that the circulation cannot be arranged when it is switched off. A bypass line with its own circulation pump (BP) is available for this case. Case 3 = Defrost with heat pump energy. The rock heat pump works. Alt 1 and Alt 2 differ in their work cases 2 (thawing only with brine solution) in that in alt 1 the thawing loops are then connected in series with the energy wells and in Alt 2 they are connected in parallel. In order to be able to control the parallel flow through the thawing loops and through the energy wells, respectively, in the parallel-coupled case (alt 2), the control units R1 and R2 are present. These can, for example, consist of permanently tuned valves or be controlled valves or circulation pumps. BP can also be a part of this control system.
