摘 要：
In order to study the thermal storage equipment suitable for assembled solar greenhouse,heat store-release devices with water bag,water curtain and dual source heat pump were installed in the greenhouse,and their quantity of heat,warming effect,heat store-release costs,energy saving rate,and other indicators were studied.The test results show that,in sunny days,the heat storage capacity and heat release capacity of dual source heat pump are the highest,which are 704.99 MJ and 539.62 MJ respectively,the average temperature during heat releasing period at night is 3.51℃ higher than the controlled greenhouse,the energy saving rate is29.58% and the cost is high;The heat storage capacity and heat release capacity of water curtain active heat store-release equipment are 434.62 MJ and 337.19 MJ respectively,the average temperature during heat releasing period is 3.13℃ higher than the controlled greenhouse,and the energy saving rate is 70.53%;The heat storage capacity and heat release capacity of water bag heat store-release equipment are the lowest,which are 167.42 MJ and 157.16 MJ respectively,the average temperature during heat releasing period is1.40℃ higher,and energy saving rate is 69.18%.In cloudy days,the heat storage capacity and heat release capacity of dual source heat pump are 185.73 MJ and 222.78 MJ respectively,the average temperature during heat releasing period at night is 2.08℃ higher than the controlled greenhouse.Through the comprehensive performance analysis,water curtain active heat store-release equipment is adopted,because its advantages of high energy saving rate and low cost.Dual source heat pump heat store-release equipment can be chosen according to the producing needs,due to its high quantity of heat and warming effect.
