Types of Air Conditioning Systems: Window, Split, Packaged and Central
An HVAC designer will recommend different types of air conditioning systems for different applications. The most commonly used are described in this article.
HVAC stands for Heating, Venitlation and Air-Conditioning. Within this topic you’ll find articles on how to choose the best air conditioner for your home or office, how refrigerators work, and all about designing a room for optimum ventilation.

In condensers the refrigerant gives up the heat that is has absorbed in the evaporator. There are three main types of condensers: air cooled condensers, water cooled condensers and evaporative condensers.
Window air conditioners are one of the most commonly used and cheapest type of air conditioners. To install one of these units, you need the space to make a slot in the wall, and there should also be some open space behind the wall.
Mechanical Engineering is one of the widest fields of engineering. It includes various fields like manufacturing processes, automobiles, thermal & hydraulic power plants, refrigerators & air-conditioners, aeroplanes, rockets, cryogenics, and much more.
Split air conditioners are used for small rooms and halls, usually in places where window air conditioners cannot be installed. However, these days many people prefer split air conditioner units even for places where window air conditioners can be fitted.
The process of refrigeration is used for many day-to-day applications. It is used to chill water, make ice and ice cream, keep your food fresh and a host of other purposes. Let us try to know the basics of the refrigeration process.
This article describes the arrangement of compressors in the package air conditioners with multiple compressors. It also describes the capacity control system in these units.
There are four important parts of a refrigerator: compressor, condenser, expansion valve and evaporator. Freon gas passes through all these parts continuously in the form of a cycle and undergoes various phase and temperature and pressure transformations. Freon acts as the media for transfer of heat.
Central air conditioning plants are used for applications like big hotels, large buildings having multiple floors, hospitals, etc, where very high cooling loads are required. The article describes various possible arrangements of central air conditioning plants.
Air conditioning is the process of maintaining comfortable conditions inside a closed space. It controls temperature, humidity, air flow rate and the cleanliness of air inside a room.
In many cases especially in places of heavy rainfall, the dehumidification carried out by air-conditioners is not sufficient because the moisture content of the air is extremely high. In such cases portable dehumidifiers are very useful and convenient to use.
The HVAC system selected haphazardly for your home or office can turn out to be insufficient or highly expensive. For achieving comfortable conditions at optimum costs, HVAC design for your home or office is important.
The refrigerating compressor is considered to be the heart of refrigeration and air-conditioning systems. The compressor compresses the refrigerant and consumes most of the power of refrigerating and air-conditioning units.
Heat is generated inside the room from various sources. Some of these include heat gained by the walls, heat entering from the windows, heat generated by the people, electrical equipments etc.
The refrigerant undergoes various changes throughout the vapor compression cycle and it is in the evaporator where it actually produces the cooling effect. The evaporator is usually a closed insulated space where the refrigerant absorbs heat from the substance or food to be cooled.
