Refrigeration and Air Conditioning

Keeping refrigeration and air conditioning working is essential to the modern world.

Why is this skill important?

A refrigeration and air conditioning technician works on commercial, residential, public, and industrial projects, including transportation and storage. There is a direct relationship between the nature and quality of the product and service required and the resulting cost and price; therefore, this branch of engineering covers a wide range of products and services. It is also essential for the refrigeration and air conditioning technician to meet high and growing standards of service in order to comply with the requirements of the customer and maintain and grow the business. Refrigeration and air conditioning is closely associated with other parts of the construction and transportation industries at all stages and is equally affected by rapid change in these sectors, including growing environmental trends, and requirements.

The refrigeration and air conditioning technician generally works inside domestic, commercial, or public buildings during and after construction and production, and on projects of all sizes and types. He or she will plan and design, install, test, commission, report, maintain, fault find, and repair systems to a high standard. Work organization and self-management, communication and interpersonal skills, problem solving, flexibility and a deep body of knowledge are the universal attributes of the outstanding practitioner.

Whether the refrigeration and air conditioning technician is working alone or in a team, the individual takes on a high level of personal responsibility and autonomy. From ensuring a safe and reliable installation and maintenance service, in accordance with relevant standards, through to diagnosing malfunctions, upgrading and commissioning, and fault finding and correction, the skills of concentration, precision, accuracy, and attention to detail at every step in the process are crucial. Mistakes may be very expensive and damaging, while substandard work will significantly undermine the performance of the building or equipment that it is intended to serve.

The cold chain plays a significant role in modern global trade in all food commodities, and skilled refrigeration and air conditioning technician are crucial in this connection, as well as in supplying human comfort at home and in buildings. Reducing environmental impact by using environmentally friendly refrigerants (low GWP-refrigerants), minimizing leakage, and reducing energy consumption. Minimizing heat load and improving efficiency is an important part of this occupation’s contribution to a sustainable future on Earth, by reducing the consumption of fossil fuels like coal, gas and oil, in favour of electricity generation.
