【Abstract】 An air-conditioning system operating with vapor compression refrigeration and ejector refrigeration was proposed and designed for a comprehensive building. The operating principle of proposed air-conditioning system, load calculation, design calculation of ejector refrigeration system with R245 fa, design calculation and selection of air conditioning system were presented in detail. By comparing the energy consumption of the new hybrid air-conditioning system with traditional vapor compression refrigeration air conditioning system under design conditions, the proposed hybrid air-conditioning system can save electricity power by 23.18% and the performance is up to more than 30%, which is considered to have certain prospects.更多还原
