How much Power does an Air Source Heat Pump Consume?

Since the power consumption of an air source heat pump is related to many factors, and the normal power consumption of an air source heat pump is a situation of heating hot water under the condition that the waste heat of the air can be used, so we must first understand the power consumption of the air source heat pump if it can work according to its principle. To this end, you can understand the following four points.

Working principle of air source heat pump

The air source heat pump can use the energy in the air and is an energy carrier. The air source heat pump can absorb some low-temperature heat in the air, and then after the medium is processed, it is compressed by the compressor and heated up, and finally the heat exchange is realized by exchanging heat with water through the heat exchanger. Therefore, if the air source heat pump can use waste heat, it is very efficient. Compared with ordinary electricity, if the same amount of electricity is consumed, the hot water that the air source heat pump can produce is 4 to 6 times that of ordinary electricity.

Rated power of air source heat pump

For household air source heat pumps, the rated power is generally within a certain range. For example, the power of the air source heat pump with a water tank below 200 liters in the market is generally about 440w. The power of the air source heat pump with a water tank of 200L to 300L is generally 500w. Therefore, the actual input power of the air source heat pump is not high, and the difference is not very large.

Power consumption of air source heat pump

Since the air source heat pump has very high requirements for the waste heat in the air, it is very energy-saving to heat hot water in summer. But it is much worse in winter. For example, in the high temperature season in summer, using an air source heat pump to heat a box of water generally takes about an hour, so the power consumption at this time is less than 1 kWh. But in the winter when the temperature is very low, it takes more than two hours or even three hours, and some even longer. In this case, heating a box of water may require 1.5 kWh of electricity, and some even 2 kWh of electricity.

Example

For example, each of us needs to use 50 liters of hot water every day. If there are four people in our family, then the hot water required every day is 200 liters. So at this time, we calculate the power consumption of the air source heat pump based on 200 liters. For example, if we use an air source heat pump to raise tap water from 15℃ to 55℃, then it is basically around 1.5 kWh, which is less than one yuan. From this, we can see that the power consumption of the air source heat pump is also very low.
