Abstract
A triple effect absorption method and apparatus having a high coefficient of performance. Two single effect absorption circuits are combined with heat exchange occurring between a condenser and absorber of a high temperature circuit, and a generator of a low temperature circuit. The evaporators of both the high and low temperature circuits provide cooling to an external heat load.
Claims14
A heat absorption method for an absorption chiller comprising:
- (a) providing a first absorption system circuit for operation within a first temperature range, said first circuit having generator means, condenser means, evaporator means, and absorber means operatively connected together;
- (b) providing a second absorption system circuit for operation within a second temperature range which has a lower maximum temperature than said first temperature range, said second circuit having generator means, condenser means, evaporator means, and absorber means operatively connected together;
- (c) heat exchanging refrigerant and absorber solution from said first circuit condenser and absorber with absorption solution from said generator of said second circuit;
- and
- (d) said evaporator of said first circuit and said evaporator of said second circuit both being disposed in thermal communication with an external heat load to withdraw heat from said heat load.
