HVAC systems work by absorbing and cooling warm air, evaporating it, and distributing it through fans. They also produce warm air through combustion gases. Some HVAC systems intentionally use outside air for heating and cooling, such as Dedicated Outdoor Air Systems (DOAS). Understanding these dynamics helps optimize indoor air quality and system efficiency.
HVAC systems have an average lifespan of 10-20 years, with commercial systems lasting 15-30 years. Factors affecting their longevity include coastal regions, environment, and unit size. Regular maintenance, including inspection, replacement, lubrication, and cleaning, is crucial for extended system life. Regular maintenance extends the lifespan, reduces repair costs, and enhances indoor air quality.
The HVAC compressor is a crucial component in heating and cooling systems, compressing refrigerant to create high-pressure, high-temperature gas. It works by absorbing heat from the evaporator coil, converting it into a low-pressure gas, and then converting it back into a low-pressure gas. There are various types of compressors, including screw, centrifugal, rotary, scroll, and reciprocating compressors. Understanding compressors helps optimize system performance.
Comprehensive information about air conditioning ( AC Systems ) mechanisms, Types and AC components and AC functions.
Conditioning air means simultaneously controlling temperature, humidity, and cleanliness to make a living and working space comfortable. Various air conditioning ( AC Systems ) mechanisms exist today, from the simple split system to the most complex central air conditioning systems.
The main aim of air conditioning is to create thermal comfort and obtain quality fresh indoor air.
Our mission is to change people’s lives. We do that by working within our community to create a positive change.
