Purus has evolved from its sister company Direct Diesels Ltd – we had been asked to get involved with other aspects of temperature control – we in 2004 set up Purus to specialize in air conditioning and air filtration in all aspects of domestic and industry.
The principle of air conditioning is to absorb energy in one place and release it in another place.
The process requires an indoor unit, an outdoor unit and copper piping to connect both. Through the piping the refrigerant flows from one unit to another. It is the refrigerant that absorbs the energy in one unit and releases it in the other.
As with all air conditioning systems the principle remains the same whereby the heat is removed from one area and replaced with chilled dry air and the hot air is expelled, normally to the outside atmosphere. As you can see from this typical example of a air conditioning system, the ambient air is drawn over the condensor that can best described as a ‘radiator’ as seen on motor vehicles but instead of water running through the system it contains a refrigerant gas.
On its journey around the system it has three main stages; the evaporator contains the sub-cooled refrigerant and air blows through its veins to release the chilled dry air into the room, the condenser contains the high temperature gas that once again air is blown through the veins collecting the heat as it passes through and this is then expelled outside.
Our units are both heat and cool option advantages of heating with the system can be a quick response to temperature and humidity levels.
