How To Enable The Cascade Air Source Heat Pump

The cascade air source heat pump unit is equipped with a high degree of automation. Proper use of the air source heat pump and regular checks of unit status during use are very important for improving the efficiency and service life of the equipment. Here we talk about the correct use of air-source heat pumps and daily maintenance from several aspects.

Re-enable precautions

After the cascade air source heat pump unit has been out of service for a long time, to ensure stable operation of the heat pump system, check the system thoroughly before restarting. Thoroughly inspect and clean the unit. Clean the piping system. Check water pumps, regulating valves, and other equipment of the system. Check that all wire connections are tight. If the parts on the unit are damaged and need to be replaced, the corresponding manufacturer of the unit should be contacted (or a professional HVAC company to provide services for you) for replacement, should use the brand of original factory accessories, and not randomly replace any different parts. For safety's sake, remember to power off before disassembly. Before the air source heat pump unit starts heating in winter, add a certain amount of antifreeze in the water circulation loop to prevent freezing of the circulating liquid in winter. Before starting, the air source heat pump can not be piled around debris. Generally speaking, there should be at least 80 centimeters of distance around the main engine, and there should be no blocking objects within 2 meters of the front of the fan.

System pipeline inspection

Check whether all the valves of the cascade air source heat pump are open. If the division is done, check whether the electric heating actuator of each way is normal, the most intuitive is to see whether the flowmeter on the diversity collector has flow. It is suggested that the floor heating system should choose the diversity collector with a flowmeter as far as possible, to facilitate later debugging and maintenance. Switch the indoor temperature control to the heating mode, and set the temperature higher than the real-time indoor temperature. Wait for 2 ~ 3 minutes to observe whether the electric heating actuator is started or whether the flow meter has flow. The water system pipeline is affected by the sun and rain for a long time, and the insulation layer may be damaged. Please check and maintain regularly to avoid affecting the unit's performance.

In addition, if the cascade air source heat pumpunit is not used often or is out of service in winter, all water in the unit, water pump, and outdoor pipeline should be emptied to prevent the unit from freezing and cutting off the power supply. You can also fill the main engine and the end with some nitrogen to prevent corrosion of the pipeline from contacting the air.
