How the evaporator and condenser coils work together ?

The evaporator and condenser coils inside a central air conditioner or heat pump make it possible for these systems to complete the heat exchange process, which is the basis of refrigerated cooling and, in the case of heat pumps, heating. The coils form a loop and, even though they’re continuous, each has a different function.

The role of the Evaporator Coils:

Located inside the blower compartment or air handler, the Evaporator Coils holds the chilled refrigerant that the compressor moves into it. As the air from the blower fan moves over the coil, the cold refrigerant removes the heat from your home’s air. The refrigerant becomes warmer and travels to the condenser coil outdoors. With a heat pump, the process reverses in the winter and the Evaporator Coils expels heat from the refrigerant into your home, instead of absorbing it and taking it outdoors. Most heat pumps have auxiliary heating elements that are part of the Evaporator Coils components to supply heat when temperatures fall below a certain point.

Katariyaa produces a large variety of Evaporator coils for all segments of the HVAC & R industry. We specialise in detailed custom design to meet the exact end-use requirements.

The Importance of a Clean Evaporator Coil

The efficiency of your system depends on the cleanliness and regular maintenance of your evaporator coil. Your AC unit's energy consumption can rise by up to 30% due to dirty coils. Poorly maintained coils can also result in additional issues with the system, including frozen coils, an overheated compressor, and poor cooling efficiency because of limited heat transmission.

At Katariyaa Coils, efficiency and durable life are the insignias of all refrigeration and air conditioning systems. With this in mind, our Evaporator coils will be strongly constructed, incorporating advanced heat exchange technology that will guarantee reliability of operation and energy efficiency. We also provide customized solutions to cater to specific needs, enabling our clients to reap the benefits of customized products to meet their specific cooling requirements.
