ABSTRACT:
A solar-energized heating and cooling system for a building utilizes solar heated water and a hot storage tank to provide space heating, to provide domestic hot water, and to operate absorption type refrigerating apparatus which cools water to be stored in a cold storage tank. When required, the stored cold water is used for space cooling. The domestic water subsystem utilizes the thermosiphon effect to maintain a tank of domestic hot water at substantially the temperature of the hot storage tank, without a pump. An emergency cooling system diverts circulating solar heated water through an outdoor heat radiator whenever water temperature becomes undesirably high. If hot water pressure becomes abnormally high or low, a water flush system directs source water through the solar collectors to a drain, to cool and stabilize pressure in the collectors. A logic system regulates valving and the operation of various equipment so that the changing heating and cooling needs of the building are accommodated automatically.
