Problems encountered in extreme situations of air source heat pump application

Release Time：2021-07-21

As the name implies, air energy heat pump is a water heater that uses the energy in the air to generate heat energy. It can provide the whole family with different hot water needs 24 hours a day, high water pressure and constant temperature, and can consume less energy to complete the above requirements.
Air source heat pump water heater is a high degree of automation equipment, the use of regular unit status inspection, if the unit can be long-term effective maintenance and maintenance, the operation reliability and service life of the air source heat pump unit will be unexpectedly improved.
It can produce domestic hot water at home, and at the same time, it can also release air-conditioning like air-conditioning to meet various refrigeration needs of the kitchen, and it can also achieve dehumidification in local spaces such as balconies, storage rooms, garages, etc. to prevent items from becoming moldy and deteriorated or to dry clothes quickly.
Therefore, for the air source heat pump, it is necessary to regularly check whether the power supply of the unit and the wiring of the electrical system are firm, and whether the electrical components in the unit are abnormal in operation. If there is any abnormal situation of the air source heat pump, it should be repaired and replaced in time. The waterway filter installed outside the unit should be cleaned regularly to ensure the water quality in the system is clean, so as to avoid the damage of the main unit due to the dirty filter.

Traditional air source heat pumps operating at minus 10-25 degrees may appear:
The unit cannot defrost: in frequent rain and snow weather and low temperature, the defrosting ability of the unit is easily weakened. As the suction of the unit is too small, the air density that can be inhaled by the air source heat pump is reduced. As time accumulates, the thickness of the cool layer is getting higher and higher. Therefore, the unit will reduce the circulation amount of refrigerant and the overall heating capacity due to the decrease of air conversion capacity.
Compressors are prone to failure: the exhaust temperature rises rapidly, and the working fluid is overheated. When the working fluid is overheated, the thermal conductivity of the working fluid in the condenser decreases sharply. At the same time, the temperature of the lubricating oil rises and the viscosity drops, which affects the compressor. Normal lubrication, followed by different technologies involved in the two.
