供房间中全年性空气调节用的生活空调器(图1)的热力计算要分别地对每一种运行工况进行计算,并求解两种意义不同的问题。制冷工况是空调器的基本计算工况。在制冷工况中对于选定的蒸发温度t_0、冷凝温度t_R情况下,计算换热设备、压缩机和毛细管,并计算析湿系数ζ。该计算方法以及推荐的制冷剂工作温度的选择方法和析湿系数ζ已被许多作者十分详细地研究过。在制热工况中求解它的逆问题:当已知换热器表面面积和压缩机时,计算蒸发温度t_0、冷凝温度t_K、析湿系数ζ、供热能力Q_K和转换系数μ(供
The thermodynamic calculations of the air-conditioners for the air conditioning in the room (Figure 1) are to be calculated separately for each operating condition and to solve two different problems. The cooling condition is the basic calculation condition of the air conditioner. In the case of the cooling conditions for the selected evaporation temperature t_0, condensation temperature t_R, the heat exchange device, the compressor, and the capillary are calculated, and the dehydration coefficient ζ is calculated. The calculation method and the selection method for the working temperature of the recommended refrigerant and the dehydration coefficient have been studied in great detail by many authors. Solve its inverse problem in heating conditions: When the heat exchanger surface area and the compressor are known, calculate the evaporation temperature t_0, the condensation temperature t_K, the dehydration coefficient ζ, the heating capacity Q_K, and the conversion coefficient μ (for
