- Abstract:
- For the designers to master the calculation method of the air source heat pump hot water system, some aspects included in the Standard for Design of Building Water Supply and Drainage(GB 50015-2019)such as the applicability of air source heat pump hot water system and auxiliary heat source, the operation and calculation of heating capacity of auxiliary heat source, heat capacity of air source heat pump unit, the volume of heat water storage tank and so on were analyzed. The calculation methods about air source heat pump unit, auxiliary heat source and heat water storage tank were improved. It was pointed out that air source heat pump hot water system is not only suitable for hot summer/warm winter and hot summer/cold winter zones, but also suitable for severe cold and cold zones. The technical content of air source heat pump in the standard should be elaborated independently from water source heat pump. Whether the mean air temperature of coldest months and the average temperature of spring equinox and autumn equinox months are reasonable parameters or not should be studied further.
