With the northern heating season approaching, the user who has installed the air heating heat pump, do not rush to turn on the air heating heat pump first, before turning on the air heating heat pump, you need to do the following checks to ensure stable operation throughout the heating season, comfortable heating.
1// Check power supply
Check the power switch and equipment wire wiring whether there is loose, should be wired firmly; power cord and controller signal whether aging or damage, such as the need for timely replacement.
2// Clean up debris around the main unit
Clean up the debris around the host, keep the host around to leave enough distance, so as to ensure the heat transfer effect of the unit, if too close is likely to send the cold air back to the host, the indoor temperature can not realize the setting, the unit will keep running, increasing costs. When the air source heat pump unit failure users do not have to worry too much, remember not to arbitrarily control the unit panel, timely contact with the manufacturer to avoid the deepening of the fault.
3// Power on standby
Before starting the machine, it must be connected to the power supply standby (power on and off), so that the compressor warms up for 24 hours before starting the machine, otherwise there will be damage to the compressor may be caused.
4// Comprehensive inspection of piping, mainframe, pumps, filters
Wait before starting the machine, fully check the pipeline, host, pump, filter, etc.. See whether there is water leakage in the pipeline; whether the host, water pump, end of each filter is dirty and clogged and needs to be cleaned; whether the valves of each pipeline are open; whether the fluorine pressure table is in the normal range (more than 0.5Mbar) and so on. If the floor heating has been used for more than 3-5 years, and the last heating season heating is not good, you can consider cleaning the floor heating, remember to find a professional floor heating cleaning personnel door-to-door service, and beware of personal operation caused by improper damage.
Special tip: If you are using underfloor heating for the first time, as the underfloor heating will be pressure tested with gas pumped inside during renovation to see if there are any leaks, it is important to let out the gas inside before you use the underfloor heating for the first time.
5// The temperature should not be adjusted too high
The temperature should not be set too high after the air heat pump is turned on, because too high will overload the compressor, consume energy and affect the service life of the host. When turning on, it is recommended to set the temperature a little higher than the expected temperature, so that the warm air quickly reach the expected temperature, and wait until the temperature feels appropriate and then adjusted down to low airflow or energy-saving mode, in order to reduce energy consumption and noise. Heating to ensure that the indoor temperature to reach about 20 ℃ can be, this temperature is also the best temperature of the human body sense, is conducive to good health.
6// The unit circuits must be guaranteed to be properly energized in winter
①Short-time shutdown
If the unit is not running for a short period of time, make sure that the power supply to the unit and pump is not disconnected to prevent the water system from freezing.
②Long downtime
If the unit is not used for a long time need to pay attention to the following issues: 1. check the unit for leaks, must ensure that there is refrigerant in the unit; 2. such as the ambient temperature is lower than 0 ℃, and in the event of a prolonged power outage, should be all the water in the system in a timely manner, to prevent the water system from freezing, if the water can not be all discharged, it should be added with the appropriate antifreeze; 3. turn off the unit as well as the power supply of the water pump.
③Precautions for a long shutdown and restart of the unit
1. Refill the system with water, while opening the exhaust valve to exhaust air, close the exhaust valve after filling with water; 2. Turn on the power, check the flow rate as well as the water system for leakage; 3. The unit must be energized for 24 hours to warm up the compressor before it is allowed to start running.
7// Important tips for winter frost protection of air source heat pumps
①Keep energized
Please don't cut off the power when it is out of use or no one is using it for a short time, because the units are all set with anti-freezing protection function, in the normal operation of the unit or the circulating pump is running normally, in order to ensure that the unit does not freeze the circulating pipeline in the cold weather, so that the unit can run normally, so the water temperature can be appropriately adjusted downward to achieve the purpose of saving electricity. (It is recommended that the water temperature can be set to 25-30℃ when it is not used for a short period of time, so as to save electricity and prevent freezing).
②Pipe insulation
Adequately do a good job of pipe protection measures, please pay attention to check whether the pipe insulation wrapping is in place to avoid pipe freezing and blockage. (Air source water heater pipe insulation can be used insulation cotton and polyurethane foam two, small pipe diameter are generally used insulation cotton insulation, large pipe with polyurethane foam insulation).
③Ice treatment
If you find that the air source heat pump pipes have frozen but not yet cracked, do not knock the pipes or pour hot water on them, but wait for them to melt naturally.
