The goal is to control the temperature of indoor air, why is water used for heating and cooling? Hydronic HVAC&R systems have many performance advantages: –

• Water has a higher density and specific heat capacity than air. As a result, hydronic piping requires less space than air ducts.
• Blowing air vertically to upper floors is difficult, inefficient and impractical. Pumping water through hydronic pipes is much simpler.
• Air ducts can spread dust, mould and other harmful substances which may affect our health. On the other hand, hydronic HVAC&R systems have a separate air handler for each area.

The world of refrigeration extends far beyond more visible applications such as domestic fridges, ice rinks or supermarket display cabinet chillers. Refrigeration is present in a broad range of sectors. It plays an often-overlooked role in healthcare, energy and the environment. Its significant contributions to society also underscore its economic importance. In Australia, the refrigeration industry is estimated to contribute about 1.7 per cent to the national GDP.

At the heart of the HVAC & R system is to supply power, and uninterrupted electricity flow enabling the air conditioning system to operate and run at its optimal level. Electrical and mechanical fault finding performed by our skilled Technicians is essential to extending the life and maintaining the air conditioning system. Having trained Technicians ensures that we adhere to Industry Appliance Standards and with Occupational Health and Safety Act practices.

The thermal transfer of heating and cooling through air, water and refrigeration distribution systems. This can be in the form of convection, conduction, or radiation-based. Most homes in Australia will need to be heated during the course of a year. Depending on the climate, heating and/or cooling can account for 20 to 50 per cent of energy used in Australian homes.

Most of the refrigeration and air conditioning plant relies on some form of an automatic control system to maintain environmental conditions within the conditioned space. The HVAC&R Technician is highly skilled and knowledgeable when fault finding, and repairs are required, this is done through the automatic control systems and can vary due to its complexity.

Once considered a luxury, air conditioning has become an essential facet of everyday living. More than four million Australians use at least one air conditioning unit in their homes.

The operational airflow variables are adjustable and programmed to create design comfort for conditions, including volume, temperature, humidity, pressure, air movement and air quality set points or targets within the occupied space.
