As a new type of clean and environmentally friendly heating equipment, air source heat pumps have received strong support from the coal-to-electricity coal-fired boiler reconstruction project in the north in the past two years, which is one of the reasons for the rapid popularization of air source heat pumps. Many people use air source heat pumps but have some wrong ways to save power, so that air source heat pumps are capped with “electric tigers” and “power consumers”.
If your home’s air source heat pump is an “electric tiger”, you need to reflect on whether your use method has a few misunderstandings about energy saving. How to save electricity when use heat pump?
Myth # 1: Heat pump save energy by heating right now when need?
Some consumers turn on the temperature control when they need it, and turn it off when they go out, thinking that this will save power, but in fact it will consume more energy. The underfloor heating system is a low-temperature operation system. Generally, the hot water coils for underfloor heating are laid in the concrete, so the floor radiant heating system has good heat storage. In this case, the use effect of the underfloor heating system is lagging. That is, it takes a certain amount of time for the temperature of the room to reach the set temperature after the system is turned on, and the room temperature does not drop rapidly after the system is turned off, and it takes a long time to reduce the temperature. Frequent switching not only fails to save energy, but also increases the operating cost of the heating system. At the same time, frequently turning on or off the heating system will also reduce the service life of the floor heating system.
The correct way: You can lower the temperature by a few degrees in the less commonly used room. When you leave the house for a long time, you only need to reduce the temperature of the thermostat by a few degrees. However, it should be noted that if there is equipment in the room or the pipeline is afraid of frost damage, it must still be opened to a certain temperature to prevent the equipment or pipeline from freezing and cracking.
Misunderstanding 2: The higher outlet water temperature, the better
In order to increase the indoor temperature quickly, many users will set the outlet water temperature of the air source heat pump to be higher than 41 ° C (the standard outlet water temperature when the unit is sent for inspection). According to the experts from Linsam’s air-energy heat pumps, each 1 ° C rise in the temperature of the water from the air-source heat pump will decrease the heating capacity by 1% to 2%. In the case of similar conditions such as the envelope structure, the higher the water temperature, the lower the efficiency, and the power consumption of the air source heat pump heating system will increase accordingly.
Air source heat pumps are energy-saving and environmentally friendly equipment. There is nothing wrong with this. The key is that you have to use them correctly. Anyway, this is what you often call “power consumers.” Only the correct use of the pump can perfectly reflect the advantages of air source heat pumps. Heating equipment saves 200% of electricity.
