Title:
HEAT PUMP-TYPE REFRIGERATION AND HEATING DEVICE, REFRIGERANT AND HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2016/169516
Kind Code:
A1
Abstract:
A heat pump-type refrigeration and heating device (1), a refrigerant and a heat exchanger. The heat pump-type refrigeration and heating device (1) is provided with an additional condenser (8) which condenses the refrigerant during both refrigerating and heating operations. The cross-sectional area of the tubing through which flows the refrigerant of the additional condenser (8) is smaller than the cross-sectional area of the outlet tube (95), so as to prevent evaporation of the refrigerant of the additional condenser (8) during refrigerating and heating operations. The outlet tube (95) is connected to a compressor (2) and to a four-way valve (3). The refrigerant contains monochlorodifluoromethane or difluoromethane and 1, 1, 1, 2-tetrafluoroethane.
