系统压力的概念
Concept of system pressure
制冷系统压力是制冷剂R22在空调管路中循环到不同位置所对应的压力，由于R22是在气液之间循环变化的，伴随着吸热和放热，所以外界环境的温度对其有明显的影响，一般情况下，环境温度高，压力值变大，环境温度低，压力值变小。
The pressure of the refrigeration system is the pressure corresponding to the refrigerant R22 circulating to different positions in the air conditioning pipeline. As R22 circulates between gas and liquid, along with heat absorption and heat release, the temperature of the external environment has a significant impact on it. Generally, when the ambient temperature is high, the pressure value increases, while when the ambient temperature is low, the pressure value decreases.
制冷系统在运行时可分高、低压两部分。
The refrigeration system can be divided into high and low pressure parts during operation.
高压段为压缩机的排气口至节流阀前，这一段称为高压压力；
High pressure section refers to the section from the exhaust port of the compressor to the front of the throttle valve, which is called high pressure;
低压段为节流阀出口至压缩机的吸气口这一部分，这一段称为低压压力。
Low pressure section refers to the section from the outlet of throttle valve to the suction port of compressor, which is called low pressure.
平衡压力是指压缩型托辊 吸水树脂 天津水处理设备 邯郸断桥铝门窗 唐山防水 检查井模具 沟盖板模具机不工作时，高低压平衡时的压力；
Balance pressure refers to the pressure when high and low pressure are balanced when the compressor is not working;
三个压力的测量都是在室外机气阀的维修口上，制冷运转时为低压压力；制热运转时为高压压力；不工作时为平衡压力。
The three pressures are measured at the maintenance port of the air valve of the outdoor unit, and they are low pressure during refrigeration operation; High pressure during heating operation; When not working, it is the balance pressure.
