VRV Air Conditioning Systems

What is a VRV Air Conditioning System?

A VRV system air conditioner is the most energy efficient way to bring the comfort of conditioned air to your family home, office complex or multi-level building. It is the system widely chosen by large hotels, hospitals and multi-level buildings housing a large number of occupants.

The VRV system, meaning Variable Refrigerant Volume or Variable Refrigerant Flow (VRF) regulates the flow of refrigerant according to the temperature of the space to be cooled.

Comprising an outdoor unit and an indoor unit, the VRV system is able to provide air at a consistent and comfortable temperature to the space to be cooled or heated. By varying the refrigerant flow and maintaining an air temperature within a close range, a steady room temperature is reached more rapidly and with less energy.

One outdoor VRV unit can serve one or many indoor units or several outdoor units can be coupled to serve many indoor units depending on the building type, function and number of occupants.

One critical component that enables it to work successfully is the Digital Thermal Expansion (DTE) valve. This valve senses the refrigerant gas temperature flowing in the circuit and maintains air, that is entering the room, is delivered at a constant temperature generally within +/-0.5° of the set temperature.

The other important feature of the VRV system is the “Inverter” compressor. The compressor self-regulates its workload according to signals from the DTE valve. The compressor supplies sufficient refrigerant to keep the room temperature at a constant level with the added benefit of reducing cyclical energy demand with associated fluctuating energy requirements.

Why is a VRV Air Conditioning System better?

A VRV system air conditioner is much quieter and is automatically responsive to applied heat loads from changing air temperature characteristics or increased occupant numbers.

Some of the many benefits include:

  • More consistent comfort levels for all occupants within a given work space.
  • Ability to independently vary comfort levels in different zones
  • Maintains a close temperature range and a more consistent energy demand.
  • Energy costs are may be optimised using a reverse cycle heat recovery function. This allows heat to be removed from high solar loaded areas to other parts of the same building that may otherwise require supplemental heating.

How can we help find the best VRV Air Conditioning System for you?

The most suitable VRV system for your use depends on a number of factors including the building function, internal volume, number of doors and windows and the number of anticipated occupants.

We, at Alliance Climate Control can design a system to meet your needs, bringing together the best products from VRV technology.

We will visit your site or work with your architectural team to determine the best mix of outdoor and indoor units, whether it be a family residence, hospital or multi-level, multi-function building.

We will also be there with you during the installation and commissioning process to make sure the selected unit will deliver your absolutely satisfaction before sign-off.

I was extremely impressed with Alliance Climate Control (ACC). They were very professional and provided me with comprehensive detail and quotes before commencing any jobs. Joshua came out and serviced our main unit and a separate unit, and I was most impressed with Joshua's product knowledge, technical ability and customer service. I would use ACC again without ANY hesitation. Strongly recommended!

I cannot rate Alliance highly enough. It’s always tricky trying to find the right business to choose for the first time and after reading all the positive reviews online I booked right away. Jake was absolutely brilliant in his first visit, recommended great solutions that fit within my budget and was extremely professional and lovely to deal with. Today Jake and Kody serviced our aircon unit and completed an eco clean and it’s like new! Thank you both, really appreciate all your work and will definitely use your services again.

Sam, Rob,Shadi and Adam were part of the installation team that have just left .. They were a delight to have in the house.Rarely do you get a company that under promises and over delivers. I have to say that the experience from our first call in for a repair quote to the final installation of a new Actron system was terrific.We had a thorough explanation of the repair and replace options . When we decided to go for the full replacement , we were taken through the options very clearly and thoroughly. Thanks for that Josh and Michael. The system is in,, the house is cool and and any debris taken away and the working space was vacuumed. All with a minimum of fuss.There is an obvious pride in the workmanship and a genuine sense of teamwork . The guys seemed to really enjoy working for the company and with each other . (Grumpy tradesmen are a pet hate of mine...)A premium product at a reasonable price . Thanks guys.

Alliance is easily the most professional team of air-con technicians I have used. I had Jake Perri come out to my apartment today, he was punctual, easy going and extremely professional. I live in an apartment and my external unit is locked in cage, which we were unable to access it as the building manager was dealing with a fire alarm, Jake (wanting to make sure the job get's done before XMAS) actually was able to climb over the fence to ensure that he was able to complete his review of the unit, found the root cause and stayed on the phone to the manufacturer for 30 + mins to ensure he could source the replacement piece,I highly recommend the team at Alliance and Jake in particular - extremely helpful blokeCheers,

I recently had Alliance CC install a Mitsubishi multi-split system in our apartment in October 2019 with three heads and one compressor on the balcony. Kirk came out to do an initial quote (for free) a short while back and unlike the others, he provided an extremely detailed quote including exact parts, specifications and pricing. The documentation was able to be submitted easily to our strata/owners corp for quick approval as it was well documented, and approval came quickly. In the lead up to accepting the quote, Kirk and James were very helpful and supportive as I asked for advice on exactly what specification I needed for my small apartment without overspending since I had a tight budget.On the day, I met Hayden, Shadi, Thomas, Corey and Connor who were extremely professional in how they interacted with myself as well as the building manager. They were well organised, had all the tools they needed and were able to be left on their own to do everything properly. The quality of the installation was excellent with the colour-matching and method they ran wires and pipes throughout the apartment looking as seamless as possible (refer to photos below). This was a pretty large job given the limitations in our apartment's strict strata/by-laws and the floorplan. One month later, everything is working perfectly and I have no complaints, and am also glad that we right-sized the compressor unit.The only negative I'd have (which is nitpicking) is that whilst they offer to clean up after themselves and in fairness, go above and beyond what most tradies would do (eg mopping the floor), there was still dust and mess everywhere behind doors/walls/etc... and even though they used their own drop sheets to cover things, unfortunately they didn't fully cover some key furniture such as our baby's cot and our bed resulting in a lot of drilling dust being everywhere. Whilst a minor complaint, it was still frustrating since it meant we had to spend the evening cleaning up and washing linen before we could sleep. To Alliance's credit again, when I did have concerns over an area of the plaster which hadn't set properly, Kirk offered to come out straight away and he fixed it immediately, and also found a few spots I had missed and cleaned it with their industrial vacuum. This instant response to feedback was a surprise and I appreciated this.So all in all, I would highly recommend Alliance for others looking for an air conditioning installation especially a complex one. The all in one quote for both supply and installation means you have a single point of contact both now and in the future (should something go wrong), their quotes are detailed and specific (so you can easily get strata approval) and they stand by the quality of their work and are willing to fix anything which isn't 100%. As far as I can tell, the work was all done to a very high standard without any shortcuts and the end result is one that I'm happy to look at everyday. The professionalism demonstrated by all of their staff both from a sales perspective and the team actually doing the installation should be commended and left a very positive impression on me.I would also mention the reason why we chose Alliance over the competitors which were cheaper is that the detailed quote they provided was clearly itemised and they had a 'no surprises' approach which I really appreciated. The quote was exactly what we paid and there was no deviation/cash-grab at the end. The big box retailers who had their recommended installers come out tended to give very rough back of the envelope quotes which didn't inspire confidence that there wouldn't be a surprise later on especially on things such as piping/wiring lengths, proposed routes, and the need for a pump given the length of distance. These are things which none of the other installers even considered or mentioned and I suspect would've been an awkward situation during the installation if it turned out we needed them.

We would like to thank Ilce, Adam, Thomas and Corey. They installed our aircon and did a fantastic job. We were worried about which tradie to hire. But Ilce and the team were professional, polite and awesome. They did a great job and I would recommend them to anybody.

The Team’s led by Kirk and Hayden did an amazing job! In what was a very difficult and unusual layout in our house, the team found a way to get the tricky install in place and looking and working fantastically. The whole team including, Jake, Ilce, Shane, Adam and Corey the sparky, worked extremely hard over two full days to implement our system, this was over multiple level and included high above ground work. From start to finish they had a Say.Do & Can.Do approach from quote to completion. The owners should be proud to have team with such a customer centric approach.

We had a couple gentleman from Alliance Climate Control, Sam and Adam come around to install our ducted Air Conditioning System over the weekend. They did an amazing job and had it up and running in no time at all. Sam and Adam were very friendly and professional, they kept everything very clean and tidy while they were working. The Air Conditioning is running great just in time for the hot weather to come. Thanks Alliance, Sam and Adam for the work you did.
