The power consumption of air source heat pumps under normal circumstances is very low. It can be said that it is the lowest power consumption appliance in all our homes. But its actual use effect is often not the case. Some friends even reported that the power consumption in winter is very high. This shows that the power consumption of air source heat pumps is greatly affected by the environment.
1. Increased power consumption in winter.
The increase in power consumption of air source heat pumps in winter is the most common situation. This is because the outdoor temperature is low in winter, and the air source heat pump can use very little waste heat. At this time, the advantages of air source heat pumps cannot be reflected. The most fundamental reason is that the water output of the air source heat pump is less than the demand for hot water. The working time of the heat pump is doubled. As the ambient temperature decreases, the heat exchange capacity of the air source heat pump also decreases. For example, when the ambient temperature is below 5°C, the power consumption will increase greatly, and the outlet water temperature will also decrease. Therefore, when selecting, you must pay attention to the applicable temperature of the air source heat pump.
2. The evaporator inside the air source heat pump is dusty, or in areas with poor water quality, the condenser is scaled.
Whether it is dust accumulation on the evaporator or scaling on the condenser, the heat exchange area will be greatly reduced. After the heat exchange area is reduced, the power consumption will increase. Because the heat generated cannot be used. When the situation is serious, the high pressure protection of the compressor may also occur.
3. Unreasonable settings during use.
The unreasonable settings during use mentioned here generally refer to the high water temperature we set. For example, the water temperature is set at 70℃. In this case, we start to replenish water after using up part of the hot water. However, the hot water temperature after replenishment is still high, basically reaching above 50℃. This will cause the air source heat pump to work at a high temperature all the time, resulting in a sharp drop in efficiency and increased power consumption.
4. The water tank or pipe insulation does not meet the requirements, resulting in a serious increase in power consumption.
Because the hot water generated by the air source heat pump must be stored in the water tank, and when we use it, we transport water from the water tank to our room through pipes. Therefore, in this process, if the hot water has a poor insulation effect, it will exchange heat with the outside world. Especially in winter, the heat dissipates quickly. This causes the air source heat pump to reheat the hot water, which consumes a lot of electricity.
5. Many friends have installed circulating water at home, which is what we call circulating hot water, or hot water with a return water system.
Whether it is circulating hot water or a return water system, in the process of continuous circulation, the circulating pump will first increase the power consumption. In addition, when the hot water is circulating, it will inevitably exchange heat with the outside world, and the water temperature will drop. These will also increase the power consumption of the air source heat pump.
