Refrigeration and Air Conditioning

This Refrigeration and Air Conditioning Certificate program will teach you the different forms of heating, ventilation, and air conditioning technology. Refrigeration and Air Conditioning systems provide cooling to residential and commercial buildings. You will study the fundamental principles that determine how they operate, the basic components of Refrigeration and Air Conditioning systems, and their environmental requirements.

The main purpose of using air conditioning and refrigeration is to lower the temperature of a particular area compared to the surroundings. The application of these can be seen in various domestic and industrial appliances such as ACs and Refrigerators.

Refrigeration is the process of removal of unwanted heat from a selected object, substance, or space and its transfer to another object, substance, or space. Naturally, thermal energy is seen flowing from a hotter place to a colder place.

Air conditioning is the process of treating and distributing air to control temperature, humidity, and air quality in selected areas. For temperature and humidity control, air is moved over chilled or heated coils and/or a spray of water at a controlled temperature. Direct water sprays also remove dust and odors. Other air cleaning systems may include mechanical separation, adhesion, screening, filtration, or static attraction, depending on the type of air contaminants encountered and the required air quality.
