Small self contained air conditioner

Types of small self-contained air conditioners

The small self-contained air conditioner is an independently functioning indoor cooling unit that uses refrigerant to absorb internal heat. Unlike central HVAC systems that depend on external compressors to cool spaces, self-contained units house all their components within one cabinet.

• Small self-contained air conditioner units:

  Self-contained air conditioners are compact units that house all of the air conditioning components in one space, including the evaporator, condenser, compressor, and expansion valve. The unit then releases the internal heat externally by itself.

• Portable air conditioner:

  Portable A/Cs have the same parts in a self-contained unit and come with wheels for maneuverability. These units require ventilation through an exhaust hose that connects to a window or another opening. Additionally, some portable air conditioners have a dehumidification mode that allows them to drain moisture from the air through a hose or an internal reservoir.

• Through-the-wall air conditioner:

  TTW self-contained A/Cs are designed for wall mounting, where the entire unit fits through the wall. The front and rear sections are flush with the wall. Because of this, TTW indoor units can provide a better aesthetic and take up less space compared to window models. TTW air conditioners are often used in commercial buildings, hotels, and multifamily housing.

• Packaged terminal air conditioner:

  PTACs are self-contained A/Cs often used in hotel rooms and apartment buildings. They are larger, floor-mounted units that provide heating and cooling. PTACs are similar to TTW air conditioners in design but are installed through the wall between two separate rooms. Moreover, like most self-contained air conditioners, PTACs also use refrigerant to cool and heat space.

  Drain holes are available to remove any condensed water formed during the cooling process. There can be one or two drain holes, depending on the design and application of the indoor AC unit.

• Functionalities

  Functionality is a critical specifications factor as it defines what an AC unit can do beyond just cooling. Many self-contained units also provide heating. Special models include dehumidifiers and units with both cooling and heating.

Maintenance

Small self-contained air conditioners require minimal maintenance, but periodic inspection and cleaning of critical parts ensure optimal performance, efficiency, and longevity. Some tips are given below.

• Inspect the air filter every month and clean or replace it if needed. A clean air filter allows sufficient air to pass through the indoor unit.
• Clean the condenser and evaporator coils every 3-6 months to remove dirt and debris.
• Check the indoor and outdoor units for any obstructions, like plants or debris, to ensure adequate airflow.
• Inspect the drain port for clogs or debris to allow condensate water to pass freely.
• Lubricate the fan and blower motor's moving parts to reduce wear and tear.
