Air-conditioning plant return liquid cooling - with liquid-cooled condenser linked to hot water central-heating system circuit

摘要

The purpose is to enable return cooling of the cooling liquid to take place, without incorporating additional apparatus and wasting space, in an air-conditioning plant which includes a compressor, a liquid-cooled condenser and a vaporiser mounted in the airflow of a blower. When the plant is used for cooling, the condenser is placed in direct contact with the liquid circulation of a hot water central central heating system; when it is used as a heating apparatus a radiator can be provided for the vaporiser, and the radiator in turn may be connected to the central heating circuit, both radiator and condenser junction ducts incorporating alternately electrically activated valves so that one or the other is subjected to the system's flow according to whether the plant is being used for heating or for cooling.
