Claims

[Scope of utility model registration request]

In a solar heat collection system in which water is circulated by a circulation pump between a heat collection plate into which sunlight is incident and a heat storage tank, and solar energy is converted into hot water and stored in the heat storage tank, the temperature between the inlet and the outlet of the heat collection plate is are communicated by a pipe through a switching means, and when the outside temperature reaches a predetermined set value, the switching means is activated to short-circuit the inlet and outlet of the heat collecting plate, thereby circulating water within the short circuit. and a controller that switches the switching means to circulate water between the heat collecting plate and the heat storage tank when the outside air temperature reaches another set value lower than the set value. Solar heat collection system.
