Packaged terminal air conditioner is one of the most widely used types of air conditioners. If Packaged terminal air conditioner is silent operation and elegant appearance, the main reason behind popularity. Let's look at the various parts of these units.

Packaged terminal air conditioner has two main parts: an indoor unit and an outdoor unit. The outdoor unit contains split AC, such as compressor, condenser, expansion valve and other important components. Let's take a closer look at these parts:

1. Compressor:

Compressor is the most important part of any air conditioner. Before sending it to the condenser, it compresses the refrigerant and increases its pressure. The size of the compressor varies according to the required air conditioning load. Air-tight compressors are used in most domestic Packaged terminal air conditioner. In such a compressor, the motor for driving the shaft is located inside the sealing unit and is not visible outside. External power must be supplied to the compressor for compressing refrigerant, and in the process, a lot of heat generated in the compressor must be removed in some way.

2. Condenser:

The condenser used in the outdoor unit of the Packaged terminal air conditioner has one or more rows of condenser coil according to the sizes of the air conditioning unit and the compressor. The tonnage of more air conditioners and compressors is more coil turns and rows. High-temperature and high-pressure refrigerant from the compressor enters the condenser, where heat must be discarded. The pipes are made of copper because of the high heat transfer rate. The condenser is also covered with aluminum fins so that the heat of the refrigerant can be removed at a faster rate.

3. Condenser cooling fan:

The heat generated in the compressor must be thrown out, otherwise the compressor will become too hot for a long time and its motor coil will burn, resulting in complete breakdown of the compressor and the entire air conditioner. In addition, the refrigerant in the condenser coil must be cooled so that its temperature becomes low enough to produce a cooling effect after expansion. The condenser cooling fan is a common fan with three or four blades and is driven by a motor. The cooling fan is located in front of the compressor and on the condenser coil. As the fan blades rotate, it absorbs ambient air from the open space and blows it through the compressor, condenser and aluminum fins to cool them. Hot air is returned to the open space and the circulation of air is not hindered.

4. Expansion valve:

Expansion valves are usually copper capillaries with several turns of coils. In large-capacity Packaged terminal air conditioner, thermostatic expansion valve operated automatically by electric power is used. High-pressure and medium-temperature refrigerant leaves the condenser and enters the expansion valve, and its temperature and pressure suddenly drop.
