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.

A solar-energized system for heating, cooling and supplying domestic hot water for a building space, comprising: a hot liquid storage tank; means for collecting solar energy as heat and transferring the heat to flowing liquid; first liquid circulation means directing liquid from the hot storage tank through the solar energy collecting means and returning the heated liquid to the hot storage tank; a cold liquid storage tank; chiller means operable on heat from a hot liquid stream, for cooling a second liquid stream; second circulation means for circulating hot liquid from the hot storage tank to the chiller means, as said hot liquid stream, and returning it to the hot storage tank; third circulation means for circulating liquid from the cold storage tank to the chiller means as said second liquid stream and returning the chilled liquid to the cold storage tank; at least one heat exchanger and blower means for passing air over the heat exchanger to supply heating and cooling to the building space; fourth circulation means for circulating hot liquid when required from the hot storage tank to the heat exchanger and returning it to the hot storage tank; fifth circulation means for circulating chilled liquid when required from the cold storage tank to the heat exchanger and returning it to the cold storage tank; and a domestic hot water system including a domestic hot water tank, a heat exchanger coil positioned within the hot liquid storage tank, conduits connecting the domestic hot water tank with each end of the coil, means for circulating water from the domestic tank through the coil when heating is required, means supplying source water when required to the conduit upstream of the coil, and a conduit near the upper end of the domestic tank for drawing off heated water for domestic use.
