Abstract (en)
[origin: WO2006039580A1] A method for providing controllable amounts of heat recovery from a refrigerant circuit includes the steps of providing a cooling circuit comprising a compressor, a condenser, an expansion device and an evaporator connected in series by refrigerant flow lines; providing a heat recovery circuit comprising a heat recovery heat exchanger, the heat recovery circuit being connected to the cooling circuit so that the heat recovery heat exchanger is in parallel with the condenser, and the heat recovery heat exchanger being in heat exchange relationship with a fluid to be heated based upon an end-user demand for heat; and selectively flowing refrigerant through the condenser of the cooling circuit and the heat recovery heat exchanger of the heat recovery circuit so as to maintain temperature of the fluid within a temperature band around a set point provided by the end user.
