Description

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a parallel linkage device of an air source heat pump. Background Art

[0002] Air source heat pumps use the energy in the air as their main power, and use a small amount of electricity to drive the compressor to achieve energy transfer. They can effectively reduce the large amount of pollutant emissions brought to the atmospheric environment by traditional heating, ensure heating effectiveness while achieving energy conservation and environmental protection. In large buildings or industrial parks, in order to meet large heating or cooling needs, multiple air source heat pumps can be connected in parallel.

[0003] However, the traditional parallel connection method of air source heat pumps generally uses multiple pipes and tees to connect with each other. The structure is complicated, and the heat pumps are interconnected and cannot work independently. They can only be opened and closed at the same time, which makes it difficult to meet different heating or cooling needs. In addition, since the pipelines for transporting liquids are long, when the pipeline gates are opened and closed, the air pressure in the pipeline changes suddenly, which will cause water hammer phenomenon, and impact the pipeline, which may cause pipeline rupture, water leakage, etc. for a long time.

[0004] In order to solve this technical problem, the utility model proposes an air source heat pump parallel linkage device. Utility Model Content
