ABSTRACT:
A multi-mode solar heating and cooling system including a solar collector/heat exchanger unit for heating air and/or liquid has an air compartment through which air from a point of use is circulated, and has a liquid compartment through which liquid is circulated from a liquid storage tank. An evaporator unit for chilling air and liquid by evaporation has an air moving device for selectively supplying chilled air directly to the point of use of diverting that air, and is connected to the liquid storage tank for chilling of the liquid therein. Thus, the liquid from the tank may be selectively circulated through the evaporator unit or through the solar collector/heat exchanger unit for appropriate heating or chilling of the liquid which may be simultaneously or subsequently employed for treating the air circulating through the solar collector/heat exchanger unit. Auxiliary heating and cooling coils are provided within the storage tank for standby heating or chilling of the liquid by utilization of suitable conventional heating and cooling devices, and the system is provided with retractable panels for covering the solar collector/heat exchanger unit during different operating modes. The system may also include a solar reflector device for enhancing the solar collecting efficiency of the system and may further include apparatus for selectively supplying untreated fresh air to the premises.
