Variable Refrigerant Flow & Volume
Variable Refrigerant Flow (VRF) also known as Variable Refrigerant Volume (VRV).
These types of systems consist of a number of air handling evaporator units (possibly up to 48) connected to a modular external condensing unit or multiple units.
The refrigerant flow is varied using either an inverter controlled variable speed compressor, or multiple compressors of varying capacity in response to changes in the cooling or heating requirement within the air conditioned space.
- Applications vary from home, office, retail, hotel, luxury apartments, industrial, new and retrofitted buildings
- A sophisticated control system enables switching between the heating and cooling modes in more sophisticated versions, the indoor units may operate in heating or cooling mode independently of others.
- This latter arrangement offers potential energy savings when heating and cooling are required simultaneously in different zones.
- This type of system requires no internal plant room space and offers great flexibility through the many types of air handling units available.

What our clients have to say
Arranged a service & got the best report on our air conditioner including photos, the technician explained the cost of repair and corrosion in the unit and that it would be better to replace the system, I went ahead with their recommendations for a new Mitsubishi Electric system and WOW its quiet and efficient. As for their workmanship I could not fault it, they arrived on time, even had their own vacuum cleaner and vacuumed up after they had finished, wished all trades personnel were like that! Keep up the good work Hills and will be recommending you.

Very professional and meticulous, the installers were a pleasure to work with and we highly recommend them to everyone. They made sure we understood what was going on and instructed on the workings of the system installed.
Tanya Thu, Castle Hill
Great work guys on fixing the A/C temperature issues in my office, my office staff are more than happy.
Also the cleaning of the grilles WOW they look like new certainly will have you back to service it again.
