Freezing indoor unit

Freezing indoor unit – Function and principle of operation of the indoor unit

The indoor unit is a very important part, helping the air conditioner to operate smoothly. So what do you know about this part of the chiller? Join us to learn about the function and the principle of operation of the air conditioner indoor unit in the article below.

The freezer indoor unit is a dense woven aluminum foil that covers the outside of a copper tube that contains refrigerant inside. The indoor unit absorbs the heat in the air when the fan is drawn through it. The air passing through the indoor unit will be at a low temperature and clean, it works to cool the indoor space.

Functions and operating principles of the freezer indoor unit

True to its name, the air-conditioning unit has the function of cooling and cooling the air passing through it. Air temperature after being absorbed into the indoor unit will be transferred to the outdoor unit to be pushed out. Accordingly, the heat is not lost, but only transferred from the room out through the air conditioner.

The operating principle of the indoor unit is as follows:

The indoor fan will run on a signal light when the afternoon is on. The temperature in the room at this time will usually be high, so the sensor will protect the temperature you set in the controller. At this time, the circuit board supplies power to the heater to make the fan and block work.
The vapor refrigerant passes through the capillary when the block is active. When passing through the liquid, the vapor will turn into a liquid due to the difference in pressure. Then refrigerant will be pushed into the indoor unit; The indoor fan will suck the cold air out into the room.
This process is repeated until the set room temperature is reached. At this time the heat sensor and the board will cut off the power to the heater; Block fan stopped working. If the room temperature rises, it will repeat the above cycle.
