Do residents need to charge extra electricity every month for collective heating in buildings?

Residents who collectively heat buildings have to pay extra every month. Community collective heating is central air conditioning, but it also needs a lot of electricity, and the equipment at the end uses its own electricity. Property fee is only a cost of heat and energy. The indoor temperature is only 40 degrees, even with central air conditioning. The indoor temperature of central air conditioning requires 60 degrees, and the return water temperature is 50 degrees. With central air conditioning, there is no need for heating, which increases the initial investment in vain, takes up a lot of space for building pipes and wells, and makes the interior more complicated. If you are worried about the poor heating effect at low temperature, you can increase the heat supply of the fan coil in the design. With central air conditioning, there is no need to set up radiators or floor heating. When the indoor temperature is only 40 degrees, it is best to use secondary heating, gas boiler and electric heating.
