空调管道压力不正常怎么解决

来源: 日期:2017-12-21 发布人:admin
济南空调维修厂家提醒各维修人员空调压力只和制冷剂的类型有关和空调大小是没关系的,R22制冷剂低压0.4—0.6MP高压1.6—1.9MP正常情况下吸气压力为0.35-0.55MP,排气压力在1.30-2.20MP之间,测压力一般是测的空调机组的吸气压力,如果环境温度高一点,压力就应该高一点,环境温度低一点,低压压力也适当低一点。
Ji'nan air conditioning repair air-conditioning manufacturers to remind the pressure of each maintenance personnel only and is related to the type and size of air conditioning refrigerant is never mind, R22 0.4 - 0.6MP 1.6 high pressure refrigerant low pressure and suction pressure 1.9MP under normal circumstances is 0.35-0.55MP, the exhaust pressure is between 1.30-2.20MP, the pressure is generally the suction pressure air conditioning unit test, if the ambient temperature is high a little pressure should be a little higher, the ambient temperature is low, low pressure is appropriate to a low point.
空调制冷系统下吸气压力升高的原因如下:
The reasons for the increase of suction pressure in the air conditioning refrigeration system are as follows:
1、电子膨胀阀开启过大;
1. The expansion valve of the electronic expansion valve is too large.
2、室外环境温度过高;
2. The temperature of outdoor environment is too high.
3、系统中有空气或氟过量;
3. There is an excessive amount of air or fluorine in the system.
4、室外风扇电机转速过低或不运转;
4. The speed of the outdoor fan motor is too low or not running.
5、压缩机吸排气效率降低;
5, the efficiency of the suction and exhaust of the compressor is reduced.
制冷时的运行压力正常值约为0.4~0.5MPa,制热时的运行压力约为1.5~2.1MPa,平衡压力正常值约为0.7~0.9MPa。压力随温度升高而增大,随温度降低而减小,如在冬天平衡压力可能降至0.5MPa。在额定工作电压下,制冷时单相空调正常的运行电流每1P约为4A,三相空调则每3P约为4A。制热时运行电流会增加0.5~2A。
The normal operating pressure of the refrigeration is about 0.4 ~ 0.5MPa, the operating pressure of the heat production is about 1.5 ~ 2.1MPa, and the normal value of the balance pressure is about 0.7 ~ 0.9MPa. The pressure increases with the increase of temperature and decreases with the temperature decreasing, as in the winter, the balance pressure may be reduced to 0.5MPa. Under the rated working voltage, the normal operating current of the single phase air conditioner in the refrigeration is about 4A per 1P, and the three-phase air conditioner is about 4A per 3P. The running current will increase by 0.5 ~ 2A when the heat is made.
