What is split ac?

Split ac consists of two parts, an inside unit and an outside unit. The inside unit contains the cooling coil, a blower and a filter and the outdoor unit houses the compressor, condenser coil and the expansion coil or capillary tubing.

The indoor unit is mounted on the wall of the room and the outside unit is installed outside of the required room. Both the unit are connected through a copper cable.

 Installation of split ac is easier as it does not require a long duct network. Multiple split unit can be installed using a single outside unit to cool multiple or a single large room.

  5. Voltas 1.5 Ton 3 Star Inverter Split AC (Copper 183VCZS White)

How Split ac works?

To answer the question of how a split ac works, a gas refrigerant is pumped through the cooling circuit of the unit which then pumped into the condenser unit by the compressor. Here the refrigerant turns into liquid. The liquid is then forced through the indoor evaporator coil or cooling compartment, at high pressure.

The fan of the indoor unit circulates the inside air to pass across the evaporator’s fins. The metal fins here exchange the thermal energy with the air around it. There the refrigerant turns back to gas or vapour, removing heat from the surrounding air. The cooled air is blown back to the house.

How to check AC gas level?

To check the gas level in AC is perfect or not, one can do a primary test himself. If one suspects the AC is not cooling down perfectly, he can keep his hand outside of the compressor. 

If it is throwing hot air then the gas level is ok, if not then the gas level has come down. Settling down of ice on the refrigerant line indicates a lower gas level. If the pipe between indoor and outdoor is sweat, that also indicates a low gas level.  If the machine of the indoor unit makes a hissing sound that means gas is leaking.
