空调维修必须明白三个压力

来源: 日期:2017-11-29 发布人:admin
济南空调维修系统的三个压力即:平衡压力、高压压力、低压压力;这三个压力是空调维修的重要参数。
The three pressure of Ji'nan air conditioning maintenance system: balance pressure, high pressure pressure and low pressure pressure; these three pressures are important parameters for the maintenance of air conditioning.
三个压力是制济南空调维修冷剂R22在空调管路中循环在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 three pressure is Ji'nan air conditioning maintenance refrigerant R22 cycle corresponding to the different positions of the pressure in the air conditioning pipeline, because the R22 is in a cycle of change between gas and liquid, with heat, so the temperature of the environment has an obvious influence on the. In general, the temperature of the environment is high and the pressure value becomes larger. The temperature of the environment is low and the pressure value becomes smaller.
平衡压力是指压缩机不工作时,高低压平衡时的压力;高压压力是指排气压力或冷凝压力;低压压力是指吸气压力或蒸发压力。三个压力的测量都是在室外机气阀的工艺口上,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 balance pressure refers to the pressure when the compressor is not working, and the high pressure is the exhaust pressure or the condensation pressure; the low pressure is the suction pressure or the evaporation pressure. The three pressure measurement is on the process port of the outdoor machine valve. When refrigerating is running, it is low pressure, and the high pressure is high when running.
济南空调维修制冷学的蒸发是指沸腾,因此蒸发温度就是沸点,冷凝是指一定压力下的R22在饱和状态气变液的过程,所以冷凝温度也是沸点。R22在不同压力下对应不同的沸点,如表所示为R22的蒸发压力和蒸发温度的一一对应关系。制冷学空调制冷设计的工况条件是:室外环温35℃,室内温度27度,蒸发温度+5℃,蒸发压力0.48MPa。所以空调标准制冷低压力为0.48MPa。
The evaporation of Ji'nan air conditioning maintenance refrigeration is boiling, so the evaporation temperature is boiling point. Condensation refers to the process of R22 under certain pressure in saturated state, so the condensing temperature is also boiling point. R22 corresponds to different boiling points under different pressures, as the table shows the one-to-one correspondence between the evaporation pressure and the evaporation temperature of the R22. The working conditions of refrigeration design of refrigeration air conditioning are: outdoor ring temperature 35 C, indoor temperature 27 degrees, evaporation temperature +5 C, evaporation pressure of 0.48MPa. So the low pressure of air conditioning standard refrigeration is 0.48MPa.
空调制冷管路设计相对压力制冷状态下低压压力是平衡压力的一半,所以平衡压力为0.96MPa。
The design of air conditioning refrigeration pipeline is about half of the pressure in the condition of relative pressure refrigeration, so the balance pressure is 0.96MPa.
