After the ambient temperature is below 0℃, the heating circulating water has the risk of freezing without heating, which can easily freeze the pipes and the heat pump main unit. If you leave home for a short period of time (within 3 days), you can set the temperature of the unit to the lowest, at this time the air energy heat pump will run at low load, the operation of energy consumption is also the lowest, but must not cut off power to the heat pump unit, because the air energy heat pump has antifreeze protection function, if there is a power failure, the heat pump host can not start the anti-freeze protection function, which will lead to pipe freezing and cracking and heat pump host is frozen. If no one is at home for a long time, you can empty the water of the air heat pump heating system to reduce the low-temperature environment on the pipes and heat pump host damage, of course, if in the southern region, you can not empty the circulating water in the pipes, direct power failure is also feasible, the temperature in the southern region is not enough to cause the pipes to freeze and crack and heat pump host freezing.
During the normal operation of the air heat pump, pay attention to the issue of condensate discharge, especially condensate drainage from the heat pump host is very close to the installation, in the low temperature environment air heat pump condensate freezing will be faster, and then extended to the heat pump host internal, resulting in condensate in the heat pump host internal will also freeze, and then damage the heat pump host parts. At this time, you need to promptly clean up the drainage environment around the condensate drainage pipe, to keep the condensate drainage smooth, and after icing will not affect the work of the heat pump host, you can also raise the height of the heat pump host and the ground when installing the heat pump host, you can also put insulation materials and heating devices on the condensate pipe to prevent the condensate pipe from freezing.
After the heating season, you can give the air energy heat pump heating system maintenance, clean up the scale and impurities in the pipes, and clean up the dust and lint on the heat pump mainframe to improve the efficiency of the heat pump mainframe. If the air energy heat pump is only used for heating, you can turn off the unit, you can also empty the heating water in the pipeline; if the air energy heat pump also comes with a fan coil, in the summer time, you can provide comfortable air conditioning effect for the room, but you need to do a good job of cleaning and disinfection of the fan coil before use.
