How To Maintain An Air Source Heat Pump？

Entering the heating season, the air energy heat pump has entered the normal operation stage, and by the influence of cold air, snowfall in the north of China, rain and temperature in the south, in such a cold environment, if you do not do a good job in time to prevent freezing measures, it is very easy to lead to the air energy heat pump unit freezing, affecting the user's normal heating. So what are the methods to prevent freezing of air energy heat pump in winter?
1. pipe insulation
When the ambient temperature reaches freezing point, the air heating unit water temperature drops particularly fast, if the hot water pipeline and the return pipe does not do insulation measures, it will accelerate the consumption of heat, air heating unit pipe insulation is mainly used in insulation cotton or polyurethane foam two kinds of small pipe diameter are generally insulated with insulation cotton insulation, large pipe with polyurethane foam insulation.
2. host do not just power off
Air energy heat pump water heaters and heating units in the winter outdoor temperature is low will start the automatic anti-freeze protection function.
The right way: when you don't need the host to work, set the set temperature of the unit to low, so that the unit to ensure that the antifreeze function can work, so that you can effectively solve the problem of energy waste and unit antifreeze.
3. When not in use, the water should be drained in a timely manner
If the air heat pump unit does not run in winter or need to be shut down for a long time, such as: frequent power outages, the unit is shut down at night, winter vacation, winter unit is not often used, the unit, pump, outdoor piping should be emptied of all the water, in order to prevent the unit from freezing, and cut off the power supply, set the protective cover. When running again, please make a full inspection of the system before starting the machine.
4. add antifreeze
In winter, when it is inconvenient to drain the unit and there is a possibility that the water and electricity may be cut off, the whole air energy heat pump heating system must be added and supplemented with antifreeze, and it must be based on the low temperature of the local area as an important parameter for the selection of antifreeze.
5. Don't pile up debris around the host
Poor ventilation will affect the machine heating effect, so pay attention to more cleanup, but also note that the host fan blowing out the cold air, if the front of the debris blocking, will affect the cold air dispersion, which will lead to insufficient heat in the air, affecting the heat transfer effect. Therefore, the front of the fan is good within meters can not have obstructions, too close may also send the cold air back to the host.
6, the correct pipe thawing method
If you find that the air water heater pipe has frozen but not yet cracked, do not knock the pipe or splash hot water on the pipe, you should wait for its natural melting.
Doing a good job of anti-freezing maintenance of the air energy heat pump can not only avoid the loss caused by the machine freezing, but also extend the service life.
