What occurs in an evaporator?

What occurs in an evaporator?

The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it.

Which component does refrigerant evaporate?


How do I know if my evaporator coil is frozen?

Signs That You Have a Frozen Evaporator Coil

  1. Check for ice around the outdoor refrigerant line.
  2. Look around your air handler for condensation and moisture.
  3. Is your condensate drain pan full or overflowing?
  4. Open up your air handler and inspect evaporator coil for ice and/or condensation.

What is the possible cause of an evaporator coil icing?

Low system airflow is one cause of coil icing, and a clogged filter definitely reduces airflow. When system airflow drops below specs, refrigerant circulating through the coil can’t extract sufficient heat energy. As the coil continues to condense water, ice inevitably forms on freezing coil surfaces.

How do I access my evaporator coil?

To access the coils, remove the evaporator coil access panel. To remove the access panel, remove the metal tape that seals the panel. Next, remove the screws that secure the access panel of the evaporator coil to the air handler.

How often should you clean your evaporator coils?

To minimize energy usage and reduce utility costs, the A/C coils should be cleaned at least once a year. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your air conditioning system by over 30 percent.

Where is a evaporator coil located?

Inside the home, the evaporator coil, sometimes referred to as the cooling coil, is located on the air intake side of the fan coil or the outlet side of the furnace. Its job is to remove heat from indoor air so the blower fan can return cool, refreshing air to the home.

How do I keep my evaporator coil from rusting?

How to Prevent Coil Corrosion

  1. Having an anti-corrosive coating applied on the coils once they’re clean.
  2. Installing a whole-house air cleaner on your HVAC system to capture and eliminate airborne VOCs.
  3. Rinsing down your outdoor unit with the hose every month to limit the buildup of potentially-harmful debris.

Can a evaporator coil be repaired?

In order to replace the coil and fix your evaporator coil leak, a technician will need to recover the remaining refrigerant gas, and solder in a new coil after dismantling the air conditioner. A filter / drier must also be added or replaced to absorb moister and contaminants.

What is the difference between an evaporator coil and a condenser coil?

While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid.

What is the most expensive part of an air conditioner?

air compressor

What are the 4 basic components of aircon?

Most people see their central air conditioners as overly complex devices that only a seasoned HVAC technician can understand. In reality, the average air conditioner can be broken down into four main components: the evaporator coil, compressor, condenser coil, and expansion valve.
