The unique energy-saving technology of the cascade air source heat pump just meets the market demand and uses the free heat in the air to heat, to achieve the effect of energy saving and reduce the operation and management costs. Now let's introduce how to maintain a cascade air source heat pump in detail. I hope the following information will be helpful to you.
Here is the content list:
Is water circulation maintenance of air energy heat pump troublesome
Maintenance method
Maintenance of the cascade air source heat pump is focused on water quality and the outdoor environment. Water quality is affected by raw water and scale, if the impurities in raw water are too much, it is easy to cause the blockage of the pipeline system. If a lot of scales are produced in the process of use, it will also affect the transfer of heat and cause blockage. However, the generation of scale requires temperature conditions. The hot water of air energy heat pump heating will not exceed 55℃, and the floor heating is generally within 50℃. In summer, the water temperature is only about 10℃, so the hidden danger of scale is reduced. As for raw water treatment, it can be removed and intercepted using water purifier purification and filter filtration to minimize the content of impurities in the water, so it is recommended to clean the indoor water cycle once every 2-3 years. The influence of the outdoor environment mostly comes from dust, wool, fume, and so on the influence of the outdoor heat pump main fin. Covering the surface affects the heat transfer ability of the fin. Regular flushing can improve energy efficiency and reduce the failure rate. The maintenance of the heat pump main engine needs professional personnel to do, the cleaning time can be determined according to the degree of host dirt.
Pipe insulation and anti-freezing. In winter, the outdoor temperature is relatively low, so the hot water pipe and the return water pipe should be tightly wrapped with thermal insulation foam or polyurethane foam. The small pipe diameter is generally used with thermal insulation foam, and the large pipe is wrapped with aluminum foil tape for heat insulation, to prevent the hidden danger of freezing in the main engine pipe of the cascade air source heat pump. Defrosting water discharge. The air source heat pump has a large number of defrosting water discharges when heating, defrosting water pipe position should be designed reasonably, in use should be timed, and timely clean up of defrosting water. If the defrosting drainage pipe is not properly treated, it may cause the defrosting water to reach the ground and freeze quickly in cold weather. This will not only bring inconvenience to the user's travel but also cause damage to the unit.
Therefore, in this case, the user had better clean up in time, and with the help of after-sales personnel to deal with drainage problems, and eliminate hidden dangers. Do not power off at will. Users are likely to turn off the mainframe to save power during the day when temperatures are high or when they are away from home. This is the wrong thing to do. Notice that the air source heat pump unit is heat transfer through the water as the carrier. If the power is off when used in a low-temperature environment, the main engine is likely to be frozen. The correct method should be to set the temperature of the unit to the lowest level when the main engine is not required to work so that the unit can ensure the anti-freezing function, to effectively solve the problem of energy waste and anti-freezing of the unit. In areas below 0℃ in winter, when there is no one at home for a short time, the unit can be set to run at the lowest temperature. It is not recommended to frequently power off the air source heat pump, to avoid freezing the equipment or causing pipeline failure.
The daily maintenance of the cascade air source heat pump is particularly important.
