Copper tubes with aluminum Cooling evaporator coil

Short Description:

Cooling evaporator coil is suitable for various refrigerants such as R22, R134A, R32, R290, R407c, R410a etc. The air conditioner’s evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat from the air inside the home. That is, it’s where the cold air comes from. It is often located on the inside of the AHU. It works with a condenser coil to complete the heat exchange process that produces cool air.

Description

The cooling evaporator coil for freon consist of copper tubes with Aluminum fins or copper fins housed in a sheet steel frame. The freon is supplied and discharged through headers with connections extended through the access side of the air handling unit. The evaporator coil is full of evaporated refrigerant that the compressor pumps to the metering device as a liquid then into the evaporator. The air that is pushed through the coil from the blower fan will move over the coil where the refrigerant in the evaporator will absorb the heat.

Keeping the evaporator coil clean and well-maintained is crucial to maintaining the efficiency of your system. Dirty coils can increase the energy use of the AC unit by up to 30 percent. Poorly maintained coils can also cause other problems with the system, such as poor cooling performance due to reduced heat transfer, frozen coils, and an overheating compressor.

Cleaning must be performed cautiously, as the aluminum fins are vulnerable to damage. If the filters of the unit are maintained according to the instructions, the cleaning interval will be every 3rd year, but more frequent examination is recommended.
