The problem of ground source heat pump electricity fee is answered online.

2 1 a month in winter and 8 yuan in summer. Pay the fee together all year round, that is, if your home 100 square meter, it will be 2900 yuan for the whole year. Fan: You should mean the fan of the end diffuser, about 30-50w. It's on all day, and it's only 2 degrees at most. If there is frequency conversion or temperature control, it may be less. But the main energy consumption is actually the host of ground source heat pump and the circulation of air conditioning water.

As to whether centralized operation is more cost-effective, we can roughly calculate that one year's cooling needs 120 days, heating needs 100 days, and one day 10 hours (that is, annual cooling 1200 hours and heating 1000 hours), and the area is still/. One square cooling and heating load is calculated as 50W (which is already very large), the energy efficiency ratio of air conditioning in summer is calculated as 2.5(cop), and the energy efficiency ratio of heat pump air conditioning in winter is calculated as 2. So your annual cooling load is 6000kW, electricity consumption is 2400kWh, heating load is 5000kW, and electricity consumption is 2500kWh. The annual electricity consumption is 4900kW. According to the average 0.5 yuan/kWh of residential electricity consumption (including valley electricity), your annual electricity bill is about 2,450 yuan. However, this price is based on the premise that your whole family should always turn on the air conditioner, so the calculated 2450 is on the high side. In other words, the annual air conditioning cost 1500 yuan is reasonable. However, if the ground source heat pump is used and installed uniformly in the community, the purchase cost of air conditioning can be saved. According to the area of 80 yuan/square, it is the initial investment of 8,000 yuan. So it really depends on what kind of situation you belong to.

If I were you, I would use ground source heat pump in the community. . . Don't buy your own air conditioner. . .
