Air conditioning (AC) technicians work with cooling systems to ensure proper installation, maintenance and repair. Becoming an AC technician usually involves completing a heating, ventilation, air conditioning and refrigeration (HVAC-R) degree program and/or an apprenticeship.What is refrigeration in air conditioning? Refrigeration is the process of lowering the temperature of a substance below that of its surroundings and includes production of chilled water for air conditioning or process applications.What are the four stages of refrigeration?
The refrigeration cycle contains four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components and is contained in the refrigerant loop.Is refrigerant liquid or gas?
A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle. In most cycles it undergoes phase transitions from a liquid to a gas and back again. Many working fluids have been used for such purposes.What is the safest refrigerant? Refrigerants are given indexes on what their potential effect on global warming and ozone depletion are, and ammonia is the only one that appears not to cause either of these. Ammonia is toxic and flammable, but when used in systems designed with modern technology, it is a safe refrigerant to use.What type of gas is used in air conditioners? Freon is a colorless gas that is also known as R-22. Dupont trademarked the name Freon. CFCs have been used in refrigeration and aerosol cans for many years, but in 1974, a researcher at the University of California hypothesized that CFCs were destroying the ozone layer.HVACR technicians work mostly in homes, schools, hospitals, office buildings, or factories. Their worksites may be very hot or cold because the heating and cooling systems they must repair may not be working properly and because some parts of these systems are located outdoors. Working in cramped spaces and during irregular hours is common.When installing or repairing air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery, and recycling of refrigerants. The regulations include those concerning the proper handling and disposal of fluids and pressurized gases.Some HVACR technicians sell service contracts to their clients, providing periodic maintenance of heating and cooling systems. The service usually includes inspecting the system, cleaning ducts, replacing filters, and checking refrigerant levels.Other workers sometimes help HVACR technicians install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, ductwork may be installed by sheet metal workers, electrical work by electricians, and pipework by plumbers, pipefitters, and steamfitters. Boiler systems are sometimes installed by a boilermaker.
