Frequently Asked Questions (FAQs)
Why study air conditioning and refrigeration?
HVAC or heating, ventilation and air conditioning is a highly versatile industry, with plenty of job opportunities and a competitive salary.
To pursue a career as a mechanic in this field is to challenge yourself every day working in new builds and renovations in commercial, residential and industrial settings.
If you are mechanically minded, enjoy practical work, and love working in different settings then this field might be for you.
What is difference between refrigeration and air conditioning?
In refrigeration, the apparatus supplies thermal energy from one place to a place of higher temperature whereas, in air conditioning, the thermal energy is taken from the air in order to cool the air.
Is refrigeration the same as air conditioning?
A major difference between refrigeration and air conditioning is the point of supply for the gases. Refrigeration systems have gas installed in a series of tubes. … Gases built into air conditioning units cool air that circulates through the unit; the unit then redistributes the cooled air through the room.
How long does it take to become a refrigeration mechanic?
To be certified as a Refrigeration/Air Conditioning Mechanic, you usually need to complete a three- to four-year apprenticeship program. Once you successfully complete the required on-the-job training, technical training and exams, you are awarded a journeyperson certificate.
What does an air conditioning engineer do?
Air conditioning engineers install, service and maintain systems and equipment which maintain the quality, temperature and humidity within buildings. The work of an air conditioning and refrigeration engineer may involve: Undertaking preparatory work. Inspecting, testing, certificating and commissioning.
What are the four stages of refrigeration?
The refrigeration cycle contains four major components:
- The compressor,
- The condenser,
- Expansion device, and
- evaporator
Refrigerant remains piped between these four components and is contained in the refrigerant loop. The refrigerant begins as a cool vapor and heads to the first component: the compressor.
What is the basic principle of refrigeration?
The refrigeration cycle is based on the long known physical principle that a liquid expanding into a gas extracts heat from the surrounding substance or area. (You can test this principle by simply wetting your finger and holding it up).
What are the applications of refrigeration?
Refrigeration has many applications, including 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.
What impact does air conditioning have on human life?
Sudden changes in temperature and humidity affect the respiratory system. It has a drying effect on skin and mucous membranes. It adds to ambient noise, contributing to noise pollution. The air circulation can transmit infectious respiratory diseases.
What is refrigerated air conditioning?
A refrigerated air unit is a type of air conditioning system that is not only popular, but also reliable for keeping your home at tolerable and comfortable temperatures. Refrigerated air conditioning takes air from a particular room and runs it over cool evaporative coils
How long does it take to become an AC technician?
Role Requirements for HVAC Professionals
Today, most HVAC technicians begin by taking courses at a technical school or community college. Shorter programs may last only six months and result in an HVAC technician certificate, while longer programs can last up to two years and result in an associate degree
How long does it take to become a certified HVAC?
An HVAC degree is typically completed at a trade school or community college, and it takes on average two years to complete. However, some schools offer accelerated programs that can be completed more quickly. Other schools offer a job-ready certification that can be completed in as little as 15 weeks.
