o meet the heat demand. When return temperature is lower than 30 oc , the solar collector system store the heat in the concrete tank. Summer The groundsource heat pump supply cool water for air conditioning. The solar collector system is controlled with the same in heating season. The solar collector system store the heat in the concrete tank for space heating in winter, when the temperature in the concrete tank is higher than 95 oc , the pump of solar collector system stopped. Other Season The solar collector system is controlled with the same in heating season. The solar collector system store the heat in the concrete tank for space heating in winter, when the temperature in the concrete tank is higher than 95 oc , the pump of solar collector system stopped. South Part In the heating season, solar heating system and groundsource heat pump system supply energy for space heating together. In summer, the solar heating system supply the heat to absorption refrigerator to cool water for air conditioning, when the radiation is not enough to produce higher temperature water, the groundsource heat pump system started. Heating Season The control strategy of solar system is the same with the North Part in heating season. The freeze protection of the system is antifreeze circulation system。 when the temperature in the top part of solar collector system is lower than 5 oc , the pump of solar collector system started, when temperature increased to 10 oc , the pump system stopped, part of water in solar collectors and pipes drained back into heat storage tank. When the water temperature in the heat storage tank is more than 50oc , the solar heating system directly supply energy into building for space heating. When the temperature of the return water from the heating system is higher than 45 oc and lower than 30oc , the heat pump heats the water into required temperature to meet the heat demand. When return temperature is lower than 30 oc , the water heated by solar system go into the evaporator of the heat pump to improve the efficiency of heat pump for saving more conventional energy such as electrical power. Summer The solar collector system is controlled with the same in heating season. When the temperature in heat store tank is more than 88 oc , the pump start, and the absorption refrigerator started to cool the water in the cooling storage tank. When the temperature in the top part of cooling storage tank is lower than the return water temperature, the pump for supply cooling started. The solar assisted air conditioning system and the ground heat pump are parallel operating. When the return water temperature is lower than the temperature in the bottom part of cooling storage tank, this means the cooling demand is less. Firstly, the absorption refrigeration system cools the water in the cooling sto。
