Outdoor Air Source Heat Pump Advantage Winter Maintenance Inspection

Release Time：2021-07-21

Outdoor air source heat pump requires the outlet water temperature of the heat pump to be higher than regular. As we all know, the higher the outlet water temperature of the heat pump unit, the more heat it needs, but the thermal efficiency decreases instead. The regular air source heat pump water heater has a certain working condition. Under the circumstances, the thermal efficiency is relatively high when the outlet water temperature is 40 ℃, between 3 and 5. Once the temperature reaches 50 ℃, the thermal efficiency becomes very low, below 3, some even less than 2, outdoor air source heat pump at the beginning of the design to fully take into account the problem of thermal efficiency, if the heat pump technology can not solve the problem of thermal efficiency, then, as an alternative new energy in energy saving there is no what air source heat pump advantage.
For ordinary heat pumps, the outlet temperature can only be controlled within 60 ℃. Beyond this temperature range, the service life of the equipment will be greatly shortened. Moreover, during operation, the failure rate will become very high, affecting normal production and life. When the outlet temperature of outdoor air source heat pump is within 85 ℃, the equipment is still stable and the thermal efficiency is still so high. When the outlet temperature of outdoor air source heat pump is within 60 ℃, it is more energy-efficient than ordinary heat pump, moreover, it can expand the use range of temperature and save energy at 60 ℃-85 ℃, thus becoming an indispensable alternative energy equipment in future industrial production.
Whether the operation of air source heat pump equipment is stable and design selection and technical matching is closely related, outdoor air source heat pump, first of all, according to the found working fluid to carry out various tests, when all kinds of indicators can meet the requirements of outdoor air source heat pump, according to the characteristics of the working fluid to select the required compressor type.
As the weather gets colder and colder, the user's air energy heat pump is also in a busy working state, so the daily maintenance and inspection of the air energy heat pump is also an important method to ensure the normal operation of the unit.
For the daily maintenance of air energy heat pump, users need to pay attention to check whether the key of the controller is sensitive, whether there is a fault, whether there is a problem with the air source heat pump parameters, switch state and load output at various temperatures, whether the voltage of the unit is normal, whether the water in the unit pipeline is emptying, whether there is water leakage, whether the valve is open, whether the water pressure is normal, and whether there is sound when starting, whether the parameters of the unit are normal during operation, although these are small details, it is also very noteworthy.
Another is the maintenance of the main structural components of the air energy heat pump, especially whether the connection terminals are not firmly fastened, rust and burn black. Another is whether the fin heat exchanger is dirty and blocked. If it exists, it should be cleaned in time to avoid affecting the heat exchange effect.
