Definitions

1. An evaporator coil is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air.
2. An evaporator coil is comprised of a series of coils filled with refrigerant.
3. An evaporator coil is a series of piping containing chilled refrigerant from the air conditioner (at a low pressure).
4. The Evaporator Coil is located in the indoor unit and is also referred to as the Indoor Coil.
5. The evaporator coil is mounted in the plenum or main duct junction above the furnace.

Outdoor Coil

1. It then goes to the outdoor coil, which acts as the evaporator coil.

Blower Wheels

1. The blower wheels are arranged to draw return air from the passenger compartment into the duct 19 and then through the evaporator coil.

Evaporator Coil 17

1. A condensate pump, generally referenced 50, is mounted in front of the evaporator coil 17 in coaxial alignment with the blower wheels 20.

Condensor Coil

1. Having the condensor coil in the same air path as the evaporator coil produces warm, dehumidified air.

Indoor Evaporator Coil Switches Roles

1. When the heat pump is enabled, the indoor evaporator coil switches roles and becomes the condensor coil, producing heat.

Condenser Coil

1. The air conditioning coil is positioned between an pre-cooler or evaporator coil and a re-heater or condenser coil.

Operation

1. Test: If the evaporator coil can be exposed, inspect it for frost build up after about 30 minutes of operation.

Replacing

1. Replacing a condenser without replacing the evaporator coil will, in about 95% of the cases, cause a mismatch.

Compressed

1. The refrigerant is compressed and run through a series of tubes to remove as much heat as possible, then piped to an evaporator coil as a warm liquid.

Liquid Refrigerant

1. Expansion Valve - reduces the pressure of liquid refrigerant which cools it before it enters the evaporator coil.
2. A metering device which dispenses liquid refrigerant into an evaporator coil.

Repeat

1. As the refrigerant cools down, it changes back to its liquid state and is pushed back to the evaporator coil to repeat the process.

Means

1. Hot gas bypass warms the evaporator coil and is an effective means to dry the coil.

Unit

1. To more clearly show the component parts of the unit, the evaporator coil 17 of the unit is located directly in front of the condenser coil 15.

Clean

1. To avoid this problem, check your evaporator coil every year and clean it as necessary.
2. Install an access door in the furnace or duct to clean the evaporator coil.

Fan

1. An air handler and blower unit which provides a fan to blow building air across or through the evaporator coil.

Dirty

1. Dirty evaporator coil Over time, the evaporator coil will become dirty.

Ductwork

1. Air is cooled at the evaporator coil and distributed around the house via ductwork.

Airflow

1. Technicians can increase the airflow by cleaning the evaporator coil or increasing the fan speed, but often some modification of the ductwork is needed.

Condensate

1. A drip pan is positioned beneath the evaporator coil and is arranged to pass the collected condensate into the sump of a pump housing through an inlet port.

Humidity

1. Inside, the refrigerant is drawn across the evaporator coil and humidity is removed and the air is cooled.

Moisture

1. As the air passes over the coil, any moisture in the air condenses on the evaporator coil and then runs off into a drip tray where it is drained away.
2. As the air passes over the evaporator coil and cools, moisture in the air condenses and drains off as condensate.

Cooling

1. This process moves heat (absorbed by the evaporator coil inside the cooling or refrigerated area) through the condenser coil and into outside air (or water).

Indoor Air

1. View products Evaporation Coils As indoor air passes through the indoor or evaporator coil, humidity is removed, which creates ‘cooler’ indoor air.

Home

1. After leaving the evaporator coil, the cool, dehumidified air is pushed back into the home.
2. The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling the home.
3. Inside the home is the air handler, and within this unit resides the evaporator coil.

Air Conditioning

1. Drip pan - A pan shaped to collect moisture condensing on an evaporator coil in an air conditioning of refrigeration system.

Filter

1. With normal air flow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity.

Air Filter

1. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil.

Cooling Mode

1. If the single indoor coil is being used in the cooling mode, the unbalanced condition will tend to increase the level of superheating in the evaporator coil.

Heating

1. The reversing valve directs the flow of compressed gas to the condenser coil for air conditioning or to the evaporator coil for heating.

Dehumidifies

1. The evaporator coil cools and dehumidifies the air by converting liquid refrigerant into a gas, which absorbs the heat from the air.

System

1. Dust can clog the evaporator coil, reducing the heat transfer, efficiency, and life of the system.
2. If the system is left running the indoor evaporator coil could turn into a block of ice and no air flow will come out of the vents.

Indoor Section

1. In an AC system, those components consist of the condenser (outdoor section) and the evaporator coil (indoor section).
2. The indoor section includes an evaporator coil, an evaporator fan and a scroll for directing indoor air flow.

Split System

1. Evaporator Coil - The coil that is inside your house in a split system.

Part

1. Usually, one part of the system is located inside (evaporator coil) and the other is located outside your home (condenser coil).
2. EVAPORATOR COIL - Part of split system air conditioner or heat pump indoors.

Clogged

1. With airflow across the evaporator coil in air conditioner troubleshooting you need to check the filter to make sure it is not clogged with dirt or debris.
2. If it is not, either the evaporator coil is not working properly or the drain line is clogged.

Indoor Coil

1. The evaporator coil, or indoor coil, is often described as the "cold" coil because it provides indoor cooling.
2. One additional factor that affects the efficiency of your air conditioning or heat pump system is your indoor coil (also called an evaporator coil).

Freon

1. Cooling takes place when a cold liquid (-20 degrees F. boiling point), such as Freon, passes through an evaporator coil.

Outdoor Unit

1. The refrigerant lines that run from the evaporator coil to the outdoor unit are checked in the same manner.

Temperature

1. The evaporator coil temperature is below the dew point temperature when in operation.
2. Thermostatic Expansion Valve: A metering device that limits the amount of Freon allowed into the evaporator coil as a  function of pressure and temperature.

Compressor

1. A simple stylized diagram of the refrigeration cycle: 1) condensing coil, 2) expansion valve, 3) evaporator coil, 4) compressor.

Warm Air

1. As the warm air is passed over the evaporator coil, it no longer retains the level of moisture as it can at its higher temperatures.
2. In cooling mode, a fan draws warm air from inside through a filtration system and over the evaporator coil.
3. As warm air passes over the indoor evaporator coil, it can no longer hold as much moisture as it carried at its higher temperatures.

Blower

1. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house.
2. An air handler is comprised of an evaporator coil and a blower, which circulates cooled or heated air throughout your home.
3. Make sure the blower is turning the proper RPM’s so that it pulls (or pushes) the proper amount of airflow across the evaporator coil.

Cool Air

1. Air conditioning and heat pump systems use refrigerant in the evaporator coil to cool air as it passes by.

Furnace

1. The outdoor cabinet is located next to the home and the evaporator coil is located inside the home, above or near the air handling unit (furnace or blower).
2. The very fist metal box on the top of the furnace is called the PLENUM. If you have air conditioning the evaporator coil is installed in this plenum.
3. Therefore we have to raise the evaporator coil 6" above the furnace on rails & then check the airflow.

Evaporator

1. Evaporator Coil The evaporator is located inside the air handler unit and is where the refrigerant vaporises and absorbs heat.

Pump

1. Refers to an air conditioner or heat pump that is combined with indoor components, such as an evaporator coil inside and a condenser coil outside your home.
2. Refrigerant Lines Two copper lines that connect the outdoor air conditioner or heat pump to the indoor evaporator coil.
3. When the heat pump is enabled, the indoor evaporator coil switches roles and becomes the condenser coil, producing heat.
