Two very important components in the cooling system are the evaporator and the condenser coil. The following introduction will help you understand how these coils work?

When the refrigerant circulates between the indoor unit and the outdoor unit of the cooling system, it will change from liquid to gas and back to liquid again; when the evaporator turns the refrigerant into gas in the indoor unit, it will absorb heat ; When the gaseous refrigerant is compressed back to the liquid in the outdoor unit, it releases heat, the cycle then repeats, and the heat capture and release continue.

Evaporator and condenser coils are an important part of the heat transfer process. They are usually made of copper, which makes heat transfer easy. They usually include fins or blades that increase the surface area of heat movement.

The evaporator coil contains the system refrigerant that converts from liquid to gas. The refrigerant moves through the expansion valve and enters the evaporator coil. The expansion valve reduces the pressure of the refrigerant and becomes a gas. Heat transfer occurs in these coils, creating a cold surface. The blower moves the air over the cold surface to produce cooling air to cool your home. The gaseous refrigerant moves to the outdoor unit.

The condenser coil in the outdoor unit contains refrigerant when it returns to a liquid state. The compressor increases the pressure on the gas, condensing it into a liquid. When the refrigerant changes state, it releases the heat it contains. The heat is dispersed into the outside air. The liquid refrigerant returns to the internal cycle to start again.
