Analysis and Study of Solar-Assisted Heat Pump System

Abstract:

Composition and operating modes of two different solar-assisted heat pump systems have been introduced in this paper. The advantages of compound heat pump system are analyzed compared with solo heat pump system. Solar-assisted air source heat pump system not only has the advantages, which air source heat pump system (ASHP) has, but also makes good use of renewable solar energy. It can provide cooling, heating and living hot water all the year. Solar-assisted ground source heat pump system realizes advantage complementation in various seasons between solar heat water system and ground source heat pump (GSHP) system. Solar-assisted ground source heat pump system can adjust the system operating model to solve the disadvantage of sole GSHP system, whose performance decrease for the temperature change of soil for long time operating with annual cool and heat unbalancedness. GSHP system can effectively increase the operating stability with the assistance of solar energy.
