Abstract

The invention discloses an air source heat pump system. On the basis of a conventional air source heat pump unit, an outdoor heat exchanger is divided into two parts, namely a first outdoor heat exchanger and a second outdoor heat exchanger; The two parts in the middle are connected in series as a condenser, which is beneficial to increase the condensation subcooling degree of the refrigeration cycle and improve the cooling capacity of the system; the second outdoor heat exchanger in the heating cycle circuit is connected in series with the indoor heat exchanger as a condenser; it is beneficial to slow down The time for the first outdoor heat exchanger to form a frost layer during heating operation improves the energy efficiency ratio of the system.

Description

technical field [0001] The invention relates to a novel system solution for improving the stable operation of an air source heat pump unit, which belongs to the application field of refrigeration machinery. Background technique [0002] Heat pump technology has experienced a tortuous development process since it was proposed, and has now entered a stage of comprehensive and rapid development. Especially under the environmental pressure of energy crisis and global warming, heat pump technology has become the focus of attention of various countries. The research, application and promotion of China have also risen to a level of continuous attention. As a clean and efficient energy source, air source heat pump units have been widely used in my country, but in specific applications, especially during heating operation in winter, the generation of frost layer has great impact on the energy efficiency of the system and indoor comfort. Sex has a big impact. Based on the above, this...
