Explain how an evaporator can dehumidify the air

But another advantage to an evaporator is dehumidification. When air passes through an evaporator, its temperature is reduced below the dewpoint temperature, causing moisture to condense out of the air. That moisture is the humidity in an occupied space.

What is the main purpose of an evaporator?

The evaporator removes heat from the area that is to be cooled. The desired temperature of cooling of the area will determine if refrigeration or air conditioning is desired.

How does an evaporator work in a refrigerator?

The evaporator is located inside a refrigerator and is the part that makes the items in the refrigerator cold. As the refrigerant turns from a liquid into a gas through evaporation, it cools the area around it, producing the proper environment for storing food.

What happens to air flowing through the evaporator?

As refrigerant travels through the evaporator, it absorbs heat from the air. As it absorbs heat, it vaporizes. If the system operates according to design, the refrigerant will be 100% vapor as it nears the exit of the evaporator. Before leaving the evaporator, the vapor continues absorbing heat, becoming superheated.

How do you dehumidify the air?

How does air conditioning dehumidify the air?

Air Conditioners Can Dehumidify When your AC is running, it passes air over its coils. These coils cool the air, which separates the moisture from the air. As the cooled air is piped into your house, the moisture collects in the AC and drains out.

What is the function of the evaporator and where is it located?

The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.

What evaporator means?

evaporator (plural evaporators) A piece of equipment used to evaporate the solvent from a solution. The part of a refrigerator that absorbs heat by evaporating a refrigerant.

What are the two main functions of the evaporator coil?

The evaporator coils help in the occurrence of the process of heat transfer, and as a result a cold surface created. The blower attached with your air conditioner, moves the air and also creates the cool conditioned air which decreases the temperature inside your house or any other building.

Where is the evaporator located in a refrigerator?

Evaporative coils are located on the bottom or back of the fridge, depending on the model. To best understand what the coils do, you have to understand the process a fridge goes through to cool your food. The fridge uses a chemical refrigerant to cool the unit.

How does an evaporator get cold?

As the AC runs, the compressor pulls cold, low-pressure liquid refrigerant through the tubing in the evaporator coil. Before entering the evaporator coil, the refrigerant passes through the expansion valve. This valve relieves pressure from the liquid refrigerant, which rapidly cools it.

How does an evaporator work in a chiller?

The evaporator functions as a heat exchanger such that heat captured by the process coolant flow transfers to the refrigerant. As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces.

What can reduce airflow across an evaporator?

A dirty air filter will certainly restrict the airflow across the evaporator. Every system inspection, regardless of the system issue, should include checking the air filter and changing it if required.

How does the temperature drop across an evaporator respond to reduce airflow?

Anytime the evaporator coil sees reduced airflow across its face, there will be a reduced heat load on the coil. No airflow will cause a lot of the refrigerant in the coil to remain a liquid and not vaporize. This liquid refrigerant will travel on past the evaporator coil and eventually get to the compressor.

Does the evaporator transfer heat?

Evaporator is a heat exchanger that transfers heat from the process fluid into the refrigerant causing a phase change - evaporation.

Can you dehumidify naturally?

5. Improve Airflow/Ventilation. As one of the simplest solutions to naturally dehumidify your home, you can open doors and windows to circulate air. In conjunction with this method, you can place fans in the most humid areas of your home to keep the air moving.

What machine takes the humidity out of the air?

A dehumidifier removes moisture from the air, helping prevent mould. They mostly work by drawing air in, then filtering and cooling it to condense moisture. It's then reheated before warmer and dryer air is released.

What device takes humidity out of air?

A dehumidifier is an appliance that takes moisture out of the air in your home.

Do air conditioners humidify or dehumidify?

Yes, an air conditioner does dehumidify your home. Condensation forms on a coil within the indoor unit as the AC system runs, as moisture from the air condenses and drips to a drainage system beneath it. However, it's certainly not the most cost-effective way to go about dehumidifying.

How fast does an AC dehumidify?

The more air moves over the coil, the more water condenses out and gets carried away. It takes about 15 minutes of runtime before you start getting serious dehumidification of the air, so oversized systems will not dehumidify well.
