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: Heating, Ventilation & Air-Conditioning
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.

Parts of Refrigeration Systems. Refrigerator Parts: Condenser
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 Conditioner
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.
What Is Mechanical Engineering? HVAC, Manufacturing Technology, CAD Design & Thermodynamics Introduction
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 Conditioner System: One of the Most Popular Air Conditioners
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.
Working Principle of Refrigerators: What is Refrigeration?
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.
Packaged Air Conditioner: Capacity Control System
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.
How Does A Refrigerator Work: Components of Refrigeration Cycle
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: Direct Expansion and Chilled Water
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.
How Air Conditioning Works to Maintain Comfort Condtions and Control Temperature, Humidity and Air Flow Rate
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.
Working of Dehumidifier: A Great Alternative to Air-Conditioners in High Humidity Areas
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 Important Role HVAC Design Plays In Choosing An Office Or Home HVAC System
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.
Parts of Refrigerators and Air Conditioners: Compressors, Types and How They Work
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.
Factors that Affect HVAC Design: Heat Load Calculations
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.
Air Conditioner Parts and Refrigerator Parts: Evaporator
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.
