空调维修方法介绍

空调不制热的原因一、制冷系统故障
The cause of the air conditioning without heat and the failure of the refrigeration system
1.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。过检测系统运行时的压力,会发现低压侧压力上升,高、低压压差下降。
1. one-way valve leakage. The difference between the high and low pressure differential of the refrigeration system, the increase of the temperature of the outdoor heat exchanger and the reduction of the heat obtained from the outside result in insufficient heating capacity. After testing the pressure of the system, it will be found that the pressure at the low pressure side rises and the difference between high and low pressure drops.
2.化霜控制器失灵。济南空调维修使空调无法及时转入化霜运行状态,则会出现热泵制热时蒸发器结霜现象,影响空调制热的热交换效率,导致制热量不足、甚至停机。济南空调维修应着重观察化霜感温器件是否错位、触头粘边或接触不良,风机叶轮打滑或风道阻塞,电磁阀或启动继电器失效。
The 2. frost controller is out of order. In Ji'nan, the air conditioning can not be transferred to the defrosting state in time, then the evaporator frosting occurs when heat pump is heated, which affects the heat exchange efficiency of the air conditioning heat, resulting in insufficient heat production and even shutdown. Ji'nan air conditioning maintenance should focus on whether the defrosting device is misplaced, the contact is sticky or the contact is bad, the fan impeller slips or the duct is blocked, and the solenoid valve or the starting relay is invalid.
3.制冷剂不足。可简单的进行自测来辨别是否漏氟。
3. the refrigerant is insufficient. A simple self-test can be used to determine whether or not to leak fluorine.
4.四通阀串气。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。
4. four pass valves to cross the gas. The heat pump type air conditioner switches the refrigeration and heating state through the four way valve. Some of the refrigerants that should be involved in the heat exchange are returned directly from the compressor outlet to the return pipe at the four pass valve, which leads to the decrease of the refrigerant involved in the heat exchange and the decrease of the heat exchange efficiency, resulting in the insufficient heat production.
