Parts of Air Conditioner Circuit and Temperature Unit

Air conditioner circuit

  • A closed loop made up of an evaporator coil, a compressor, a condenser coil, and an expansion valve is how an air conditioning system operates.
  • Heat from the air within a structure is absorbed by the refrigerant, which then radiates it outside.

Parts of an air conditioning system:

Evaporator Coil: This internal component, which is exposed to the air being forced over it by the air handler or blower fan, is in charge of absorbing heat from the air.

Compressor: The air conditioning system’s compressor is its brains. In order to be pumped throughout the system, it compresses the refrigerant and increases its temperature and pressure.

Condenser Coil: This component, which is outside the building, is in charge of dissipating the heat that the refrigerant in the evaporator coil has absorbed. As the refrigerant cools and condenses into a liquid, the heat is released into the ambient air.

Metering Device: The air conditioning system’s high pressure and low pressure sides are separated by the metering device. And is made to keep the low side of the system’s refrigerant flow at a particular pace. If the metering device is defective or utilised with a capacity that is insufficient the evaporator will get an improper flow of refrigerant. Expansion Valve: The expansion valve controls the flow of refrigerant into the evaporator coil and is situated between the evaporator coil and the compressor.

The basic processes in an air conditioner circuit’s operation are as follows:

  • The refrigerant is compressed by the compressor, increasing its temperature and pressure.

  • The heated, high-pressure refrigerant is delivered to the condenser coil, where it condenses into a liquid and radiates heat into the ambient air.

  • After passing through the expansion valve, when its pressure and temperature are lowered, the liquid refrigerant continues to flow.

  • After entering the evaporator coil, the cool, low-pressure refrigerant absorbs heat from the air being blasted over it by the blower fan.

  • The cycle is restarted when the refrigerant goes back to the compressor.

    A thermostat regulates the air conditioner circuit by detecting the indoor air temperature and instructing the air conditioning system to switch on or off as necessary to maintain the desired temperature.

What is the need of inverting and non inverting temperature in working of air conditioner

  • The compressor, which is in charge of compressing the refrigerant gas in the air conditioning system, is related to the inverting and non-inverting temperatures in an air conditioner.
  • An air conditioner’s cooling operation depends heavily on the compressor.
  • The temperature of the refrigerant gas at two distinct times during the compressor cycle is referred to as the inverting and non-inverting temperature.
  • The temperature where the refrigerant gas transforms from a gas to a liquid is known as the inverting temperature.
  • The non-inverting temperature is typically lower than this one. The temperature where the refrigerant gas transforms from a liquid to a gas is known as the non-inverting temperature. Usually, this temperature is lower than the temperature that inverts.
