Abstract: As a kind of heating source, air source heat pump has the characteristics of high efficiency and energy saving, and is widely used in the national “coal to electricity” project. By comparing and analyzing different heating sources, and comparing different types of household heating terminals, combined with the characteristics of air source heat pump operation, this paper recommends the solution of using air source heat pump + hot water tank + floor radiant heating + domestic hot water + cold tank + fan coil air conditioning. It has certain reference value for the selection of product mix for household and similar purposes.

Key words: Air source heat pump, Selection of heating sources, Economic analysis
