Abstract
This paper describes two advanced heat driven hybrid refrigeration and heat pump systems. Each proposed conceptual hybrid system combines both thermal compressor and turbo-compressor. The turbine (coupled to a mechanical compressor) could be driven by direct expansion of high pressure and high temperature of desorbed gas coming out of the reactor beds (Adsorption Cycle - AdSC) or high pressure and high temperature steam coming out of a boiler (Rankine Cycle - RC). In both cases, the turbo-compressor is driving a separate Vapour Compression Cycle (VCC). For each system, a model is used to predict key performance indicators like COPs when the driving temperature is ranging from 100oC to 250oC. The Hybrid RC-VCC coefficient of performance (COP) is about 1.2 to 2 times better than Hybrid AdSC-VCC ones. With a condensing temperature of 40oC, an evaporating temperature 15oC and a driving temperature of 250oC, Hybrid RC-VCC COP is 2.6 while Hybrid AdSC-VCC COP is 1.4.
