Multi-split Air Con Systems

Operating in the same way as the 'split' system, the 'Multi-split' system enables a number of indoor units to be individually controlled from a single outdoor condenser.

Up to four units can be operated in cooling only or heat only form.

'Multi-split' systems offer an ideal way to treat a number of areas whilst minimizing the space required for outdoor units.

Growing end user demand for air conditioning systems that are reliable, flexible, easy to install and yet superior in terms of comfort and control, makes VRF systems the ideal candidate for many applications such as offices, hotels, theatres, shops and hospitals.

Why VRF?

VRF systems are ideal for variable load applications, as their design is based on inverter technology. This adapts the speed of the variable-speed compressor to the varying thermal loads in a building. The Pulse Modulating Valve (PMV) in each unit controls the exact amount of refrigerant to be injected into each indoor unit.

In addition, two temperature sensors and a pressure sensor permanently control the amount of superheat, ensuring a safe operation. The pressure sensor also helps to balance the refrigerant flow. With VRF outdoor units, indoor units, Y-joints, headers and controls are all part of a single package.

Easy Installation

• Outdoor unit has a small footprint
• High piping network design flexibility - Y-joints and headers can be interconnected in any sequence
• Only 20 mm separation needed between two adjacent outdoor units
• Outdoor unit fitted with a heat exchanger drain pan
• Up to 135% overload
