Abstract

An all-year heating and cooling system incorporates an absorption refrigeration machine using solar energy as a primary heat source and a compression cycle system for boosting the temperature of the heating medium supplied to the absorption machine generator. During the heating mode, the solar collector, may be replaced by the compression cycle system if insufficient solar energy is available to satisfy the demand for heating.

Claims

1. A combination heating and cooling system comprising:

a solar collector producing a heated fluid;

an absorption machine having a generator, a condenser, an absorber, and an evaporator all connected in a closed circuit, continuous cycle absorption system, said evaporator being adapted to cool a fluid to be circulated to a load;

a compression cycle system including a condenser and an evaporator through which a refrigerant is circulated; and

means for circulating said heated fluid from said solar collector in series flow through said compression cycle system condenser and said generator.

2. A system as defined in claim 1 including heated fluid storage means receiving heated fluid from said solar collector;

an auxiliary evaporator in said storage means;

means for selectively directing said refrigerant to said auxiliary evaporator; and

means for bypassing said absorption machine and passing the fluid circulated to said load in heat exchange relation with said compression cycle system condenser.

3. A system as defined in claim 1 including means for bypassing said abosrption machine evaporator and circulating said heated fluid from said solar collector to said load.
