摘　　要：为了提高空调器的利用率,并达到节能减排的目的,设计了一种具有制冷、供暖、全天候提供热水和冷凝热回收制取热水4种功能的多功能空调器。并对所研制的多功能空调系统的热力性能进行了试验研究。结果表明:设计的多功能空调系统运行性能良好,夏季制冷和冬季供暖功能正常;夏季实现冷凝热回收功能时,该系统的平均制热水能效系数为3.57,制冷能效系数为3.31,总能效系数可达6.88;单独制热水时,其制热功率和性能系数是随着进水温度的升高而降低。在20,7,2℃的环境温度条件下,其制热功率分别为:15.572,10.57,9.02 k W,性能系数分别为:4.21,3.09,2.73。In order to improve the utilization rate of the air conditioner and achieve the goal of energy conservation and emission reduction,a multi-function air conditioner was designed,which has such four functions as cooling,heating,all-weather hot water supply and production of hot water by recovery of condensing heat.The thermal performance of the developed multifunction air conditioning system was studied experimentally.The results show that the designed multi-function air conditioner performed well,and its cooling function in summer and heating function in winter were normal;when the system performs recovery function of condensing heat in summer,its average energy efficiency coefficient for hot water production was 3.57,its energy efficiency coefficient for cooling was 3.31,and the total energy efficiency coefficient can reach 6.88;when the system produces hot water alone,its heating power and performance coefficient declined with the increase of entering water temperature.Its heating power was 15.572,10.57 and 9.02 kW,respectively,and its performance coefficient was 4.21,3.09 and 2.73 respectively under the conditions of 20℃,7℃,2℃ambient temperatures.
