Heat pump with compressor for heating system - has closed refrigerant and secondary circuit with additional vessel to mount evaporator

摘要

The heating system has a compressor mounted in a closed refrigerant circuit. The condenser transfers heat generated by heat pump to a liquid which can be fed into a boiler. The system can be regulated over a wide range ensuring high efficiency. The condenser (5) of the heat pump is connected to a vessel (7) be means of a supply and return pipeline (8, 9). This vessel is connected to the boiler (6). The vessel (7) of the boiler and the pipelines form a first secondary circuit. The evaporator (4) of the heat pump is held in another vessel (10) which forms second secondary circuit with a storage vessel (11) for liquid of lower temperature.
