Abstract (en)

Flow guiding apparatus (1) for a heating device (2), in particular an air-source heat pump water heater using a flammable refrigerant, the heating device (2) including at least a heat exchanger (8), a compressor element (15), an expansion valve (28) and a temperature sensor (29) connectable to the expansion valve (28) for monitoring the temperature of the refrigerant flowing out the heat exchanger (8), the apparatus (1) comprising a housing (3) couplable to a casing of the heating device (2) and comprising an air inlet (4) and an air outlet (5), the housing (3) defining an air flow region (7), wherein the housing (3) is configured so that the heat exchanger (8) is arranged inside the air flow region (7) for exchanging heat in said air flow region (7), and so that air is guided to flow from the air inlet (4) to the heat exchanger (8) and from the heat exchanger (8) to the air outlet (5), the air being confined in the air flow region (7) and being prevented from being in contact with the compressor element (15) and the expansion valve (28) that are arranged outside the air flow region (7), and wherein the housing (3) is shaped to place in the air flow region (7) the temperature sensor (29) connectable to the expansion valve (29).
