PURPOSE:To obtain the solar pond facilitating to maintain a concentration gradient in spite of the demand of heat at the side of heat load by a method wherein an auxiliary load device is operated based on a signal from a monitoring device when solar energy, reserved in the solar pond, has exceeded a predetermined value. CONSTITUTION:The solar energy is reserved in the bottom layer of the solar pond 1 and salt water, whose temperature has become high, is pumped out by a pump 2 to circulate again into the bottom layer of the solar pond 1 after effecting heat exchange between fluid to be used in the side of heat load in the outdoor type heat exchanger 3. On the other hand, the heat load side fluid, received the heat in the heat exchanger 3 from the primary side, supplies the heat to the heat load device 5 and is recirculated into the heat exchanger 3 after reducing the temperature thereof. The auxiliary heat load device 4a and/or the same device 4b are operated by the commanding signal of the heat load monitoring device 6, monitoring the amount of solar energy absorbed and reserved in the solar pond 1, to limit the amount of energy in the solar pond 1 or the upper limit of salt water temperature in the bottom layer of the pond, for example, and prevent boiling or convection in the solar bond 1. |
