Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC&R) is primarily used to provide and control thermal comfort and regulate a fitting indoor air quality. The HVAC industry manages indoor environments and CCS supply installation and maintenance for all components including chillers and boilers.
Heating refers to the convection-, radiation-, or conduction-based transfer of heat, through an air or water distribution system, generating warmth.
Ventilation is the deliberate movement and replacement (processing) of air in any space to improve its qualities (e.g. temperature, oxygen/CO2 levels, moisture/damp, odour, airborne particles and bacteria, pressure, stagnation). The many variables which CCS can control via ventilation mean each system is unique to the internal and surrounding ecology of a structure.
Air Conditioning (Aircon, AC, A/C, Cooling) is sometimes generalised to refer to the entire HVAC system, or any form of technology that modifies the condition of air.
Refrigeration systems function to remove heat from a place where it is not wanted and reject it into another place where the heat is unobjectionable. Refrigeration systems are closed systems; that is, they are sealed from the atmosphere. The most popular and efficient refrigerant process utilises mechanical compression [AIRAH DA02].
2007-8 estimates indicated that the installed base of non-residential HVAC systems in Australia:
• Consumes 9% of electricity produced in Australia, and more than 3.6% of Australia’s greenhouse gas emissions.
• Creates more than 55% of electrical peak demand in commercial business district buildings.
• Consumes billions of litres of water per annum in cooling towers.
• Is part of an industry worth $7 billion per annum that employs more than 95,000 people.
HVAC&R is a sector that plays an intrinsic role in everything from keeping our food fresh to making our interior spaces comfortable, if not habitable. You can always visit CCS Group’s many successful projects to see more of what HVACR really entails.
