If your air source heat pump has some unusual phenomena, don't rush to report it. Because these phenomena may not be real faults, let's learn how to deal with them together.
1. The compressor does not start?
If you find that the compressor is not running, it may not be that the machine is damaged. Check these two points:
1) Is the protection device activated? Under continuous power supply, the air source heat pump restarts immediately after shutdown, the fan runs normally, but the compressor does not run immediately. This is the compressor startup delay protection function, which avoids frequent compressor startup and protects the compressor. Just wait for about 3 minutes;
2) Sometimes it is because of compressor overheat protection. At this time, you need to find out the heat cause and restart the machine. Excessive water outlet temperature will also cause the compressor to not run. At this time, you need to reset the water temperature;
3) The default temperature difference of the heat pump startup is 5 degrees. The actual water temperature is 5 degrees lower than the set temperature before the compressor starts to work. Pay attention to check the set temperature and startup temperature difference;
4) The newly installed air source heat pump compressor does not start to work. You need to check the common end and linkage (if you do not use linkage, you need to short-circuit the common end). The heat pump does not start when it is turned on. The icon on the panel keeps flashing. This is the preheating protection function of the inverter household heat pump. It is powered on and maintained. It will start automatically after the preheating time is sufficient.
2. The air source heat pump makes noise from time to time?
During the defrosting process of the air source heat pump, the four-way valve and the solenoid valve are switched. During the operation of the heat pump, the heat exchanger will make some noises when it expands and cools slightly, and when the refrigerant flows. Don't worry, this is a normal phenomenon.
3. The fan does not run?
If the fan does not run, first check whether the fan blades are stuck by foreign objects, and then check whether the power cord of the fan is in poor contact, or whether the plug with the motherboard is loose. If so, plug the plug tightly. Finally, if the heat pump is in the defrosting process, the fan will not move, just wait until the defrosting is over.
4. Frosting of the heat exchanger?
When running in winter, because the surface temperature of the heat exchanger is lower than the ambient temperature, and the surface temperature of the heat exchanger is lower than 0℃, the surface of the heat exchanger will frost, affecting the heat exchange effect, but it doesn't matter, the air source heat pump has an intelligent defrosting function, so the air source heat pump will defrost regularly.
5. The cooling and heating effects are not good?
First, when it is found that the air source heat pump is not cooling or heating well or does not heat or cool, eliminate the following situations first:
1) Check whether there are foreign objects blocking the air inlet? It is possible that there are too many debris blocking the machine, which affects the air's ability to absorb heat from the air, resulting in a decrease in the operating efficiency of the air source heat pump. After cleaning the surrounding debris, the heating efficiency of the air source heat pump will immediately increase;
2) During the peak period of electricity consumption, the power supply voltage will be unstable, and it will not reach the normal voltage required for the operation of the heat pump. The compressor cannot work normally, and the refrigerant pressure is insufficient, which will cause the air source heat pump to not cool or have poor cooling effect. This phenomenon is more likely to occur when a large number of electrical appliances are running at the same time during high temperatures;
3) The heat pump has not been cleaned for a long time, such as a lot of dust adsorbed on the finned heat exchanger, and the air source heat pump has poor heat exchange effect when working, resulting in poor heating effect.

Finally, remind everyone to clean and maintain the air source heat pump regularly and keep the heat pump well ventilated, which will help the normal operation of the air source heat pump and provide a cool and comfortable environment. If you have other questions or need more help, please feel free to contact the professional maintenance personnel of the heat pump.
