Winter is coming, what air source heat pump units should pay attention to to prevent cold wavesThe temperature has generally cooled since October, and people have begun to add clothes and feet, and they can't help but sigh that winter is coming. So, the question is, what should be paid attention to to prevent cold wave in the air source heat pump unit? Let's take a look together.
This matter is particularly important!
The operating cost of the air source water heater is not high. Whether it is commercial equipment or household heating and cooling equipment, it cannot be powered off when it is out of service or when no one is in use. Because the air source heat pump unit is equipped with antifreeze protection function, the normal operation of the compressor can be guaranteed The air source unit does not form frost in cold weather so that the unit can operate normally.
2. Precautions for shutdown.
If the user is not at home for a long time and the air source heat pump needs to be shut down for a long time, the user needs to drain the water in the pipeline of the unit to prevent the pipeline from freezing when it stops running. After the water is discharged, the power supply must be cut off and a protective cover , The protection pipeline will not have any cold problems during the period of shutdown, and then conduct a comprehensive inspection of the air source water heater system when it is running to ensure that there is no malfunction.
3. Pipe insulation.
In winter, the ambient temperature is relatively low, not only the water temperature of the air source water heater or ordinary hot water, but the temperature drops extremely fast. If adequate insulation measures are not taken, the pipes of the air source water heater will easily freeze. Air source water heater pipe insulation mainly uses thermal insulation cotton or polyurethane foam. Small pipe diameters are generally insulated with thermal insulation cotton, and large pipes are insulated with polyurethane foam.
Before winter really comes, as long as the above corresponding measures are taken, the current air source heat pump technology can completely deal with the above problems!
