Abstract
Conventional gas engine exhaust heat absorption chiller, which is often used for space cooling, can not make temperature below -10℃, because the driving temperature of the jacket water is too low for the purpose. Although it can make temperature below -10℃ if driven by high temperature steam extracted from the exhaust gas boiler, the cooling capacity becomes very small in such a case. A hybrid refrigeration system has been newly developed to overcome this problem. The system is a turbo-charger integrated absorption system in which the compressor of 135,000rpm transfers the refrigerant from evaporator to absorber. The turbine is driven by 3 MPa vapor from exhaust gas boiler, while the jacket water, together with the spent vapor after turbine, regenerates the refrigerant. It has been proven that the capacity of the developed system is about the twice of above mentioned steam-driven conventional chiller.
