Thermodynamic Analysis of Solar Driven Vuilleumier Cycle Heat Pump

摘要

Because the refrigerant can cause serious damage to the ozone layer and form the greenhouse effect, developing green environmental protection refrigeration technology has become a consensus. Based on the view, this paper puts forward a new device called the solar energy driven VM cycle heat pump which used the natural working materials-nitrogen as the refrigerant and the clean energy-solar as the driven energy. According to build the thermodynamic model, the influence of heat source temperature on the ideal cycle has been analysed. And COP of the solar driven the VM cycle heat pump will be received. With the city of Beijing, for example, the device refrigeration COP can reach at least 1.4.
