【Abstract】 A residential central air-conditioning system was introduced which uses CO₂ transcritical refrigeration cycle.In this system the heat emitted from hot CO₂ gas of high temperature is reclaimed by using heat-reclaim heat transfer unit, it not only reduces the heat-pollution but also provides hot water.By analyzing the five running modes of this system for fitting the demand of air-conditioning in different seasons,it can be concluded that this new residential central air-conditioning system has application value for protecting environment and saving energy.更多还原
