任何一种形式的制冷系统,经过工艺设计和按装投产后,即成为一个既定的工作系统。它的机器与设备,是按一定条件下的有关数据进行计算选定的。但系统运行时,由于外界的气温、水温的相对湿度不一定与计算时所给定的数值相符,运行过程制冷剂各项参数也就与设计计算时的数值不一样。众所周知,制冷系统的运行参数就是制冷剂在系统内循环的状态参数包括:蒸发压力与温度、冷凝压力与温度、压缩机的吸气温度、
Any form of refrigeration system, after the process design and put into production, that is, to become a predetermined working system. Its machinery and equipment, according to certain conditions under the relevant data calculated selected. However, when the system is running, the relative humidity of the water temperature and the water temperature may not be consistent with the values given in the calculation. Therefore, the parameters of the refrigerant in the process of operation also differ from those of the design and calculation. As we all know, the operating parameters of the refrigeration system is the refrigerant circulating in the system state parameters include: evaporation pressure and temperature, condensing pressure and temperature, compressor suction temperature,
