When the cold air strikes, remember to take the following antifreeze protection measures for our air source heat pump. Do a good job of inspection to keep you comfortable and warm and extend the service life of the heat pump.
1. Ensure normal power supply
In the cold season, in order to ensure the normal operation of the heat pump circuit, it must be guaranteed to be powered on normally. When the heat pump water path is unobstructed, as long as there is no power outage or power failure, the antifreeze function can be activated by plugging in the air source heat pump plug. Even if the heat pump is in the off state and not put into use, this function will automatically take effect. Otherwise, if the heat pump circuit is not powered on in cold weather, the antifreeze function of the equipment will fail to cause the equipment to freeze and will not be covered by warranty.
Some users have asked: Why is their heat pump still rotating when the outdoor unit is turned off? This is because when the ambient temperature is below 4℃, the air source heat pump will automatically start the antifreeze function. This phenomenon just verifies the statement that "as long as there is no power outage, the heat pump plug will have an antifreeze function, including when the heat pump is turned off."
2. Pay attention to pipe insulation
Winter pipe insulation is very important for the operation quality of heat pumps. When the external ambient temperature is too low, the water temperature in the exposed pipes will drop rapidly. If insulation measures are not taken, the pipes will easily freeze and cause damage to the pipes. Therefore, standardizing pipe insulation measures is a necessary measure to ensure the stable operation of air source heat pumps in winter. In addition, if the pipes are frozen, do not use boiling water to melt the ice. Sudden heat is easy to explode. You should wrap the frozen part with a wet towel, and then slowly pour warm water to melt the ice, or use other heating equipment to bake and melt the ice.
3. Drain the water when the heat pump is not in use
If the air source heat pump is not running in winter or needs to be shut down for a long time, such as: frequent power outages, heat pump shutdown at night, winter holidays, and winter heat pumps are not often used, the water in the heat pump, water pump, and outdoor pipes should be completely drained to prevent the heat pump from freezing, and the power supply should be cut off and the protective cover should be put on. When running again, please conduct a comprehensive inspection of the system before starting.
4. Notes on ice treatment
When the main unit, water pump, pipes, etc. are frozen, do not use boiling water to melt the ice directly. Sudden heat can easily cause the copper pipe to burst. You can wrap the frozen part with a wet towel, and then slowly pour warm water to melt the ice, or use a heating device (such as heating tape) to dry and melt the ice. When the evaporator and the outside of the copper pipe are frozen, do not hit them with sharp objects. Use warm water to slowly inject to melt the ice.
5. Maintenance of the surrounding environment
The air source heat pump needs to absorb heat from the low-temperature air. The more heat it absorbs from the air, the more energy-saving the air source heat pump is. The amount of heat absorbed is related to the surrounding environment of the heat pump. Therefore, ensure that the air around the heat pump is smooth. Regularly remove debris and snow around the air source heat pump, and ensure that the bottom drainage is unobstructed to avoid ice in the drain pipe blocking the drainage channel of the heat pump.
If the heat pump is affected by the surrounding environment, such as debris on the evaporator fins, etc., it is necessary to regularly maintain the heat pump and clean the stains on the heat pump. After maintenance, the heat pump will not only improve energy saving, but also reduce the failure rate.
Seek professional help
The heating season is coming, and cold air will frequently visit. Users of air source heat pumps can refer to the above content to make corresponding specific inspections of the air source heat pump. At the same time, you can also call professional heat pump experts for help.
