Refrigeration

Audience: This program is excellent for the training of maintenance mechanics and electricians as well as multi-craft training needs. Request A Demo. Prerequisites : This program is designed for persons who are familiar with the principles of refrigeration theory, the basic operation of air conditioning and refrigeration systems, the proper use of hand tools and good safety practices. This program focuses on the principles involved in the refrigeration process, including methods of heat transfer, how substances change phase, and the relationship between pressure and temperature. It also shows the basic components of a refrigeration system and explains their functions. Description : This comprehensive DVD training program covers vapor compression equipment designs and refrigerants. This program focuses on various equipment designs typically used in air conditioning and refrigeration systems.

For an air conditioning system to operate with economy, the refrigerant must be used repeatedly. For this reason, all air conditioners use the same cycle of.

TEMPERATURE

Air conditioners use refrigeration to chill indoor air, taking advantage of a remarkable physical law: When a liquid converts to a gas in a process called phase conversion , it absorbs heat. Air conditioners exploit this feature of phase conversion by forcing special chemical compounds to evaporate and condense over and over again in a closed system of coils. The compounds involved are refrigerants that have properties enabling them to change at relatively low temperatures. Air conditioners also contain fans that move warm interior air over these cold, refrigerant-filled coils. In fact, central air conditioners have a whole system of ducts designed to funnel air to and from these serpentine, air-chilling coils. When hot air flows over the cold, low-pressure evaporator coils , the refrigerant inside absorbs heat as it changes from a liquid to a gaseous state. To keep cooling efficiently, the air conditioner has to convert the refrigerant gas back to a liquid again.

In other words, refrigeration means artificial human-made cooling [1] [2]. Heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir. The work of heat transfer is traditionally driven by mechanical means, but can also be driven by heat, magnetism , electricity , laser , or other means. Refrigeration has many applications, including, but not limited to: household refrigerators , industrial freezers , cryogenics , and air conditioning. Heat pumps may use the heat output of the refrigeration process, and also may be designed to be reversible, but are otherwise similar to air conditioning units.
