Abstract (en)
An air-to-water heat pump system is provided. The system includes a compressor (22) for increasing the pressure of a refrigerant; a condenser heat exchanger (24) arranged downstream of the compressor for receiving a high pressure refrigerant output from the compressor and for transferring heat from the high pressure refrigerant to a source of water; an expansion device (28) for reducing the pressure of a refrigerant; and an evaporator heat exchanger (26) for extracting heat from ambient air. The evaporator heat exchanger comprises a first tube bank (34) having a first inlet arranged to receive a high pressure refrigerant output from the condenser and a first outlet fluidly coupled to the expansion device; and a second tube bank (36) having a second inlet arranged to receive a low pressure refrigerant output from the expansion device, and a second outlet fluidly coupled to an inlet of the compressor. The first and second tube banks are arranged in close proximity to one another such that, in use, heat from the high pressure refrigerant passing through the first tube bank is transferred to the second tube bank in order to limit and/or prevent ice build-up on an external surface of the second tube bank.
