摘要
The invention is aimed to increasing the refrigerating factor of a refrigerating machine in the year-round operation thereof and can be used for vapour compression and heat-utilising refrigerating machines and devices which are provided with a liquid cooling condenser. In order to use low temperatures of ambient air during transitional and cold seasons, thereby increasing the refrigeration rate of a coolant, the temperatures of ambient air and liquid in the condenser are measured. When the temperature of liquid is higher than the temperature of ambient air, said liquid is bypassed to an additional heat exchanger and cooled therein by ambient air. The inventive liquid cooled condenser (1) for carrying out said method comprises a heat exchanger (4) provided with a fan (5) which has a drive (6) and driven valves (7, 8). Said heat exchanger and valves are embodied in such a way that they form together with the condenser a closed liquid flow circuit. Said condenser also comprises a thermostat which is provided with an ambient air temperature sensor arranged outside. The thermostat is connected to the valve and fan drive.
