What is the reason why the central air conditioner does not cool?

1. It is possible that the indoor unit and outdoor unit of the central air conditioner are not running. When encountering this problem, first check whether the air conditioner can operate normally. If it can't run normally, such as the compressor of outdoor unit. , need professional maintenance. The maintenance of central air conditioning is complicated. Never repair it at home to prevent other faults in the air conditioner.

2. It may be that the temperature adjustment is not appropriate or the doors and windows are not closed properly. If the doors and windows are not closed properly, the cooling effect of the central air conditioner will not work. At this time, you can adjust the temperature to the appropriate state according to the instructions, and then close the doors and windows.

It is possible that there is something wrong with the power supply and voltage. In these cases, you can buy a voltage regulator. With the voltage regulator, we are not afraid of the problem of insufficient voltage.

Does turning on a central air conditioner consume as much electricity as turning it on completely?

Turning on central air conditioning is not the same as turning it on completely. Because the power consumption is not equal. When you open a room, its heat load will be less, and the power consumption will naturally be less. If you choose to open more rooms, the heat load will increase and the electricity consumption will be more.

Central air conditioning refers to a large air conditioning system, which consists of a host and a terminal. The main engine is divided into water cooling unit and air cooling unit, and the terminal equipment is mainly composed of air conditioning unit and fan coil unit. There is also a Freon VRV air conditioning unit with refrigerant.

Central air conditioning is a kind of air conditioning, and its system consists of refrigeration system and air conditioning system. Its refrigeration principle is to use the cold energy provided by the air system to offset the heat generated indoors. If it is heating, it is to use the heat generated by the heating system to offset the temperature in the air.
