There is few research report on the operational performance of heat storage device.The mathematical model of solar energy collecting-storing heat system was established
and the varations of cooling capacity underdifferent water tank volumes were modeled
by taking ejecting and compressing refrigeration system under the condition of meteorological data of a typical summer day of Taiyuan.It is concluded that the stability of refrigeration system increases and the refrigerating capacity decreases with the increasing of the volume of water tank.The design of water tank volume
which is related to the operation strategy of the ejecting and compressing refrigeration system
is a comprehensive studying process.The optimal water tank volume is 0.4 m3.This research is important to the research on the solar energy heating and cooling system.
