空调不制热的三大原因

来源: 日期:2017-11-20 发布人:admin
一、制冷循环系统、控制系统故障。
Refrigeration cycle system and control system failure.
1、制冷剂不足。可简单的进行自测来辨别是否漏氟。
1, insufficient refrigerant. Simple self test to identify leakage fluoride.
2、四通阀串气。热泵型空调通过四通阀来切换制冷和制热状态。有部分本应参与热交换的制冷剂在四通阀处直接由压缩机出气管返回到回气管,导致参与热交换的制冷剂减少,热交换效率下降,从而引起制热量不足。
2, four valve leakage. The heat pump type air conditioner switches the refrigeration and heating state through the four way valve. Some refrigerants should be involved in the heat exchange and return to the trachea directly from the compressor outlet pipe at the four way valve, resulting in the reduction of refrigerant in the heat exchange and the decrease of the heat exchange efficiency, resulting in insufficient heat capacity.
3、单向阀漏气。制冷系统的高、低压压差下降,室外热交换器的温度上升,从外界获取的热量减少,导致制热量不足。
3, one-way valve leakage. The high and low pressure difference of the refrigeration system decreases, the temperature of the outdoor heat exchanger rises, and the heat from the outside decreases, which leads to the insufficient heat.
二、 使用不当
Two, improper use
1、济南空调维修在长期时候后没有及时的清洗滤网以及内部造成空气流通堵塞,一定程度上会影响空调的制热效果。
1, Ji'nan air conditioning maintenance in a long time after the timely cleaning of the filter screen and the internal air flow blockage, to some extent, will affect the heating effect of air conditioning.
2、蒸发器、冷凝器尘垢太厚,也会降低换热效果,导致制热能力下降,耗电量增加;制热温度设定过低。
2, the evaporator and the condenser dirt is too thick, will also reduce the effect of heat transfer, resulting in a decline in heating capacity, power consumption increases; the heating temperature is set too low.
3、空调房间门缝、墙洞未堵死,或是开窗开门频繁,造成室内热量流失等都会是无意间造成空调制暖不强劲的原因。
3, the air conditioning room door, the hole in the wall is not blocked, or open windows frequently caused by indoor heat loss will be inadvertently cause air conditioning heating is not strong.
三、环境因素冷暖型空调分热泵型、热泵辅助电热型和电热型三种产品,在制热量相等条件下,前两种耗电比第三种约小一半。
Three, environmental factors, air conditioning, heat pump type, heat pump assisted electric heating and electrothermal three kinds of products, in the same amount of heat, the first two kinds of power consumption is about half smaller than the third.
