Larger air-conditioning systems are usually known as either VRV or VRF systems depending on the manufacturer.
Daikin invented the technology over 30 years ago and named it VRV (Variable Refrigerant Volume); other manufacturers use the name VRF (Variable Refrigerant Flow), but the systems run in much the same way.
If you are looking at installing an air-conditioning system with more than 4 or 5 indoor units or require heat recovery (see below), then a VRV or VRF system will usually be the recommended solution.
Both systems have cooling and heating functions but some models within the range have the ability to recover either heating or cooling from one area and use it in another. For example, in winter, in a glass building with one side south-facing and the other north-facing, the people who are getting the sun may be too warm and the people in the shade too cold.
Using a heat recovery system, the excess heat from the south-facing side can be used to heat the north-facing side; the opposite would occur in cooling mode in the summer. This is a cost-effective and environmentally friendly method as the heating or cooling energy that would otherwise have been wasted is instead reused in an area where additional and costly cooling or heating would otherwise have been required.
If you are looking to cool a number of rooms or possibly an office or hotel, then Maximum has the expertise to design and install a system that will meet your requirements.
