出于节能需要,提出并设计了一种普通家庭直膨式水源空调器的节能实验,并对其进行了研究,给出了空调制冷和供暖时吸排气压力、吸排气温度、消耗功率、制冷/制热量、COP等参数,并与普通家用空调器进行了对比分析。结果表明,与普通的空调相比,在制冷的工况下,其制冷量为3 593.61W,比普通空调增加了约5.4%,而其输入总功率仅为普通空调的67.5%,能效系数COP为4.45,远高于普通空调的2.85;供暖时,其供暖量为3 407.82W,比普通空调略低,输入总功率约为普通空调的82.15%,能效系数COP为3.93,比普通空调高了0.56,节能效果显著。
In order to save energy, an energy-saving experiment of ordinary household direct-expansion water source air conditioner is proposed and designed. The research on the energy-saving experiment is given. The air-intake and exhaust pressure, , Cooling / heating capacity, COP and other parameters, and compared with ordinary household air conditioners. The results show that the cooling capacity is 3 593.61W when compared with the normal air conditioners, which is about 5.4% more than the normal air conditioners, while the total input power is only 67.5% of that of the ordinary air conditioners. The coefficient of efficiency 4.45, far higher than the 2.85 for normal air conditioners; when heating, the heating capacity is 3,407.82W, which is slightly lower than that of ordinary air conditioners. The total input power is about 82.15% of that of ordinary air conditioners, and the coefficient of efficiency coefficient COP is 3.93, which is higher than that of ordinary air conditioners 0.56, energy-saving effect is remarkable.
