Working Of Window Air Conditioner

Deemed as the simplest form of air conditioning system, the working of a window AC is anything but complicated. All the parts are assembled in an aluminum casing, which easily fits into the window frame with a little adjustment.

The AC incorporates a double shaft fan motor on which, two fans are mounted, one on the evaporator side and another on the condenser side. The location of the evaporator side would be where the room is, whereas the condenser side will be located on the opposite side so as to ward off the heat. The front panel of the unit sports adjustable louvers, which could be either vertical or horizontal.

The ‘Vent’ can be seen at the panel of the AC, which is responsible for providing fresh air to the users. The mechanical vent is a lot cheaper than its electronic counterpart. A thermostat is mounted on the return air of the AC, which controls ON/OFF operation of the compressor during operation.

As soon as the room temperature is achieved, the compressor shuts down and evaporator blower fan comes into use that sucks air from the room. After that, the discharging of conditioned air takes place, which delivers cool and dehumidified air into the room. The air mixes with the room air to bring down the temperature and humidity level.

The fresh air gets into the room from outside, courtesy of the damper. The fresh air is mixed with return air before it passed over to the cooling coil and air filter. The role of the air filter is to ensure the cooling coil remains clean so as to perform the task of heat transferring efficiently. The cooling coil is mounted in front of the evaporator.

This is the reason as to why air filter is cleaned frequently because it can only work efficiently if it is in good condition. Some window air conditioners are capable of keeping the room warm during winters, which they do with the help of a built-in heat pump unit. There is a reversing valve, which is used to accomplish this task, which reverses the flow of refrigerant during heating operation.

Advantages Of Window Air Conditioner

Window air conditioners have more advantages over split counterparts. Let’s start off with the most common one, i.e., the price.

Price: Window air conditioners cost a lot less than split air conditioners, so if your aim is to stay cool inside your house or office and you don’t have any issue with a unit being installed in place of a window, then a window AC is the best choice for you. Money saved is money earned, so you can use that money to buy some other product that you think is necessary for your house/office.

Energy Saver: An AC is going to consume more energy than a fan when you compare different types of air conditioners, the window air conditioner will consume the least amount of energy. Therefore, a window AC is less likely to give you cold sweats.

Installation: Window Air Conditioners are easier to install compared to mini split ACs or central conditioning systems. You don’t have to worry about space for an AC, plus there is no need to drill holes in the wall too. Quick and easy installation is what you get with a window AC.

Durability: When it comes to hardware-related complaints, then those are more common in split Air Conditioners. I’m writing from my personal experience that I’ve not heard much complaints regarding window air conditioners.

People have been using these machines for years and have not experienced any major issue. However, I won’t rule out exceptions, as sometimes, the piece could be faulty, which may change the entire perception towards window air conditioners, but nothing of that sort has come into my notice so far.
