Abstract:
An air conditioning system comprising a plurality of absorption refrigeration means, a fan-coil air cooling means, means for transferring heat from said air cooling means to said refrigeration means, and means for controlling the system;each said refrigeration means comprising at least one refrigerant evaporator, a refrigerant absorber means, a refrigerant generator means, and a refrigerant condenser means connected together in a closed circuit; said heat transfer means comprising an antifreeze coolant circuit that includes said fan-coil air cooling means, a coolant pump, and a heat exchanger associated with each said refrigerant evaporator; each said heat exchanger having an antifreeze coolant inlet, an anti-freeze coolant outlet, and an antifreeze coolant flow path therebetween for exchanging heat between the respective evaporator and the flowing coolant; said heat exchangers being in series flow relation with each other so that the antifreeze coolant is cooled in stages as it travels from the fan-coil air cooling means through the heat exchangers and back to the fan-coil air cooling means; said means for controlling the system comprising a central processing unit for controlling the temperature and speed of antifreeze coolant circulation.
