The most common types of air conditioning systems.
Please click any of the following titles for more information on the different air conditoning systems
Where there is an individual outdoor (condenser) to every indoor air conditioning unit
Where between two and four indoor air conditioning units are served by one outdoor. Limitations are only one point of control – All units have to be within the same area as one unit is the master and dictates all functions of the others. Can be used for Open Plan or individual offices Many different formats available
Where between two and five indoor air conditioning units are served by one outdoor. Each unit is individually temperature controllable within the mode (heating or cooling) of the overall system.
25m maximum interconnecting services to the furthest indoor unit.
Can be used for Smaller multi occupancy areas or individual offices
Many different formats available
VRV/VRF Systems are the ultimate in air conditioning systems. They open up a whole new spectrum of options. Aura can drastically cut down on you condenser space; up to 64 indoor air conditioners can operate on the same outdoor unit. A small office can be air conditioned even though it is a hundred and sixty five metres away from the condenser unit. Inverter technology ensures operating costs are kept to a minimum and heat recovery systems can even simultaneously hear and cool.
Heat recovery plays an important part in today’s world of global warming and environmental consciousness, and with a VRV/VRF system; while the comms room is producing waste heat the sales office can be using it.
Two pipe systems give the benefits of VRV/VRF technology, but do not utilise hear recovery. The system can both heat and cool, but all units have to be in the same mode together (one room cannot have heating when the rest are in cooling or vice versa) Each unit can have its own controller and the temperature be individually set between 16 – 30 degrees and will operate within the constraints of the system mode. So on a cold winter’s day the VRV/VRF system would be in heating mod and each area would be heated to their own independently controlled temperature. The difficulty comes when most offices require heating, while some other offices require cooling, perhaps because the sun is shining through their window. This is where we upgrade to a three pipe VRV/VRF system.
These systems have all the capabilities of the two pipe version and also the added benefit fo being able to simultaneously heat and cool different areas. Every area has complete control of both, mode (cooling or heating) and temperature set level. When the system is require to provide both heating and cooling at the same time, it uses the very latest technology to perform heat recovery. This means that heat removed from an area needing cooling is transferred through the system and used to raise the temperature in the areas requiring heating. This gives these systems unparalleled levels of efficiency.
