Claims16
A system for temperature conditioning room air and domestic hot water comprising a liquid circulation loop including solar collector means to transfer solar energy to the liquid, means to exchange heat between the liquid and room air, means to store the liquid, means to circulate the liquid through the loop, and means to exchange heat with a domestic hot water supply comprising a heat exchanger having a first coil in said liquid circulation loop and a second coil in heat exchange relationship with said first coil, said second coil being in a domestic hot water circulation loop which also includes domestic hot water storage means and means to circulate domestic hot water through the loop.
A system for heating or cooling room air and heating domestic hot water comprising;
- (a) a solar energy extractor comprising solar collector means for heating a liquid, means for storing the liquid, conduit means for connecting the solar collector means and storage means to form a solar energy circulation loop, and means to circulate the liquid about the loop,
- (b) heat pump means for establishing a temperature differential between a hot side and a cold side, said heat pump means including a refrigerant compressor, an evaporator on the cold side, and a condenser on the hot side,
- (c) cold side heat exchanger means for transferring heat between the evaporator and a cold side liquid circulation loop,
- (d) hot side heat exchanger means for transferring heat between the condenser and a hot side liquid circulation loop,
- (e) heat exchanger means for transferring heat between the solar energy circulation loop and a domestic hot water circulation loop,
- (f) room air heat exchanger means for transferring heat between room air and any one of said solar energy, hot side and cold side liquid circulation loops,
- (g) external heat exchanger means for rejecting heat from said heat pump hot side to the external environment,
- (h) supplemental heating means in said domestic hot water circulation loop,
- (i) means to selectively connect one of said solar energy, hot side, or cold side liquid circulation loops with said room air heat exchanger means,
- (j) means to selectively connect said external heat exchanger means to said heat pump hot side, and
- (k) control means responsive to heat demand, weather and system conditions to effect said selective connections, to control the supplemental heating means, and to control said heat pump means.
A system for heating or cooling room air and heating domestic hot water comprising;
- (a) a solar energy extractor comprising solar collector means for heating a liquid, means for storing the liquid, conduit means for connecting the solar collector means and storage means to form a solar energy circulation loop, and means to circulate the liquid about the loop,
- (b) heat pump means for establishing a temperature differential between a hot side and a cold side, said heat pump means including a refrigerant compressor, an evaporator on the cold side, and a condenser on the hot side,
- (c) cold side heat exchanger means for transferring heat between the evaporator and a cold side liquid circulation loop,
- (d) hot side heat exchanger means for transferring heat between the condenser and a hot side liquid circulation loop,
- (e) heat exchanger means for transferring heat between the solar energy circulation loop and a domestic hot water circulation loop,
- (f) room air heat exchanger means for transferring heat between room air and any one of said solar energy, hot side and cold side liquid circulation loops,
- (g) external heat exchanger means for rejecting heat from said heat pump hot side to the external environment,
- (h) means to selectively connect one of said solar energy, hot side, or cold side liquid circulation loops with said room air heat exchanger means,
- (i) means to selectively connect said external heat exchanger means to said heat pump hot side, and
- (j) control means responsive to heat demand, weather, and system conditions to effect said selective connections and to control said heat pump means.
