 The natural circulation ( tropic area usage coldest temperature +5oC)

Natural Circulation

Operation

15:Use the theory of high density cold water & low density warm water to make the natural circulation system running. The warm water goes up to upper part of tank and cold water goes down to bottom of collector . So natural circulation system tank must install on the top of tank or same level. This system may suggest to be used on tropic area with flat roof
