In recent years user expectations of air conditioning systems have significantly changed. Not only do they expect zone heating and cooling, but also demand a range of services that optimise’s room comfort and reduces energy and maintenance costs, combined with maximised simplicity and operating flexibility. The air conditioning system must be energy-efficient, versatile in installation and functionality, flexible in programming and use, reliable and easy to use. There are more and more requests for central and precise management of the system, permitting accurate and personalised calculation of the energy consumption.
VRF systems are the perfect answer to all these requirements: and are increasingly used as an alternative to traditional water based heating and cooling systems. Variable refrigerant flow benefits from the advantages of direct expansion linked to inverter control and the most sophisticated electronic control. This technology has many advantages, from the air conditioning system design to the installation and operation phase.
The wide range of indoor units makes VRF the most flexible choice to satisfy any building requirement. SMMS heat pumps provide cooling and heating, and SHRM units providing simultaneous heating and cooling – both unique, energy-efficient and versatile.
The right system for you?
There are many factors that will influence the decision on what system and products are right for you; from the size and use of the building to the degree of control you need over the climate.
With split-type air conditioning, the condenser unit that houses the motor, fan and other components, is mounted outside the building or the area being cooled, this ensures quiet operation for the indoor inverter unit. The units can be located up to 20 metres apart.
Smaller units are ideal for smaller rooms and locations. For commercial applications the range extends up to larger more powerful models: the bigger the indoor unit, the bigger the external condensing unit required. Multi splits systems allow up to five indoor units to be connected to one outdoor unit. With heat-pump technology, split systems can provide room heating as well as cooling, which is often an economical alternative to central heating systems.
