How long is the most appropriate time for the air source heat pump to start up and run every day?
For many new users of air source heat pumps, how long the start-up time is appropriate is a relatively entangled issue. Many new users think that they can meet the hot water or heat demand and can be turned on for 24 hours, so that the heat pump unit produces a large amount of heat and the unit selection is small , The initial investment is also small, is this really the case?
Through actual tests, under the condition of fixed input power, the heat production of the unit changes with the ambient temperature and the temperature of the outlet water. By extending the start-up time, the heat production can be increased theoretically, but this will increase the failure of the unit in the long term. Rate and service life. It is recommended that the operating time of the air source heat pump be within 15 hours a day, so as to ensure the normal operation of the unit and the service life of the unit, and reduce the risk of the unit failure affecting the user's use effect and reinvestment.
So, what are the problems when the air source heat pump is turned on for a long time?
1.Increasing unit failures. The air source heat pump is an energy-saving electrical component. Through the input of electric energy, the compressor is driven to work, and the air flows through the fin heat exchanger through the motor blades, so that the low-temperature refrigerant can absorb the heat in the air to produce heat; The principle can be drawn that if the compressor and the motor work for a long time, it is easy to cause problems such as heating of the coil and hardening of the circuit. Therefore, the chance of burning the compressor and the motor increases when the compressor and the motor are turned on for a long time.
2. Shorten the service life of the unit. The life of the air source heat pump is generally 15 years. Long-term operation can easily cause failures or breakage of various components. Such frequent maintenance can easily shorten the service life of the unit.
