    • 专利摘要:
    Heat exchanger with energy storage comprising a container that forms a sealed internal cavity, both first inlet and outlet ducts of a hot fluid that gives off thermal energy when circulating through the interior cavity, both second inlet and outlet ducts. a cold fluid that absorbs thermal energy when circulating through the interior cavity, energy storage means arranged in the interior cavity, where said energy storage means contain a phase change material (PCM), wherein, the exchanger comprises first temperature sensing means of the phase change material (PCM), second temperature sensing means of the circulation of the hot/cold fluids through the inner cavity and both third means temperature sensors of the hot/cold fluids in their respective first and second inlet and outlet conduits.

    It is also preferred that the second temperature sensing means (8) be two second probes (8.1, 8.2) adapted to measure temperature values of the circulation of hot / cold fluids through the inner cavity (1.1), where, said
    5 second probes (8.1, 8.2) are arranged on two sides opposite the center of the inner channel (1.3).
    For its part, it is preferred that the third temperature sensing means (9) be two pairs of third probes (9.1, 9.2) adapted to measure temperature values of the hot fluid and the cold fluid in their respective first and second inlet ducts (2, 4) and output (3, 5).
    Preferably, the first, second and third probes (7.1, 7.2, 8.1, 8.2, 9.1, 9.2) are adapted to send the censored temperature values to a control and automation unit (not shown in the figures) of the installation of air conditioning in which the heat exchanger is inserted.
    During the thermal energy charging phase, the hot fluid, coming from the primary energy source (not shown in the figures), circulates through the inner channel (1.3)
    20 formed between the first inlet duct (2) and the first outlet duct (3), providing thermal energy to the phase change material (PCM) of the energy storage means (6). This loading phase is maintained until the control and automation unit detects that a maximum setpoint temperature has been reached in the values supplied by the first probes (7.1, 7.2).
    25 During this phase, the cold fluid may be circulating simultaneously, or not, through the inner channel (1.3), in this case, between the second inlet (4) and outlet (5) ducts, provided that a use temperature it has been reached in the values supplied by the third sonsa (9.2) arranged in the second outlet duct
    30 (5) of the cold fluid.
    Next, the thermal energy discharge phase occurs. Both the maximum setpoint temperature and the operating temperature have been reached. There is no hot flow circulation and only cold fluid circulates through the inner channel (1.3) 35 absorbing the thermal energy accumulated in the phase change material (PCM)

    content in the tubes (6.1). This discharge phase is maintained until the control and automation unit detects that a minimum setpoint temperature has been reached in the values supplied by the first probes (7.1, 7.2). Which, would return to the loading phase.
    5 Likewise, the temperature values censored by the first probes (7.1, 7.2) allow to detect relevant alterations or changes in the phase change material (PCM) that affect the energy efficiency of the installation, with which, it allows to take a operation and maintenance decision in this regard.
    10 Likewise, the variation of flow conditions due to any cause, for example, fouling, existence of preferential flows through interstices arising between the tubes (6.1) and the vertical plates (10), etc., are detected thanks to the temperature values censored by the second probes (8.1, 8.2), which,
    15 also allows to make an operation and maintenance decision in this regard.
    On the other hand, the temperature values censored by the third probes (9.1, 9.2), together with previously set flow values of two circulation pumps (not shown in the figures) corresponding to hot / cold fluids,
    20 allow the control and automation unit to check the energy balance exchanged between both fluids and with the phase change material (PCM) of the energy storage means (6).
    Also, since the temperature values of the phase change material (PCM)
    25 are also known by control and automation unit, provided by the first probes (7.1, 7.2), said control and automation unit can perform a continuous verification of the energy balance of the heat exchanger and detect deviations in the operation thereof due to any cause, for example, by alterations in the temperature of phase change of the media material of
    30 energy storage (6), etc., which also makes it possible to make an operation and maintenance decision in this regard.
