VRV/VRF Solutions for Commercial Air Conditioning

VRV/VRF air conditioning systems are gaining popularity around the globe, especially in large urban areas where building space is at an all-time high. As opposed to having one massive, noisy central unit, a VRV/VRF system is adaptable to separate zones, helping to maintain a constant and comfortable internal environment.

Yet, before we get ahead of ourselves, what exactly are VRV/VRF systems and what is the difference between them?

Variable Refrigerant Volume (VRV) is a multi-split type air conditioning system that uses refrigerant as the cooling and heating medium to connect a singular outdoor condensing unit to numerous indoor units.

Variable Refrigerant Flow (VRF) is another type of air conditioning system and it is essentially the same as VRV. However, VRV is copyrighted by Daikin, whereas VRF is developed by Fujitsu.

Due to the fact that VRV/VRF systems can function with indoor units being up to 100m at a distance from one another, they are commonly implemented in commercial buildings. In such large spaces, these systems serve to direct airflow to each room and floor where the indoor units are connected. They use highly advanced technology to gently increase or decrease power, thereby reaching the desired temperature more rapidly and sustaining individual zone control. What this means is that the rooms or floors within the building can operate at different temperatures during different times of the day.

Utilising the power of AC technology

When contemplating whether to implement a VRV/VRF air conditioning system, there are definitely many benefits to take into consideration.

First and foremost, VRV/VRF systems are compatible with different types of indoor units. They come in multiple forms and sizes, making them suitable for most spaces.

Just the same, when it comes to volume, as many as 1000 indoor units can be installed on a single premise. Due to internal and external factors, such as heat emitting equipment and changes in outdoor temperatures, some areas of a building may require cooling, while at the same time, other areas may require heating. Having said that, the large volume of units does not have to be chaotic, seeing as how each unit can be controlled individually.

Last but not least, while it is only natural to assume that having all of the units running at the same time would increase energy consumption, the opposite is true. Due to the air conditioning inverters, considerable energy savings by 20 to 30% can be achieved. Therefore, VRV/VRF systems minimise or eliminate the need for expensive ductwork and offer higher efficiency.

To sum up, the key benefits of VRV/VRF air conditioning systems include:
•Precise temperature control;
•Superior comfort;
•Rapid and simultaneous response to heating & cooling requirements;
•Energy efficiency;
•Easy installation;
•Low noise operation;
•Flexible & modular designs;
•Easy to use, state-of-the-art controls

Delivering a seamless experience

The fundamental rule for implementing VRV/VRF air conditioning systems is hiring the right professional aircon experts to help with the installation process. Their expertise and knowledge are the only way to deliver systems that quick to install, easy to use, and add to the lifespan of the benefits they offer.

The bottom line is that VRV/VRF systems are a highly flexible and energy-efficient alternative to traditional heating, ventilation, and air conditioning (HVAC) systems. They are ideal for maintaining comfortable temperature control and, because the installation process is simpler than that of traditional HVAC systems, there is no need to deal with the hassle of a mess and weeks of construction.

Perhaps the best part is that these systems are highly reliable and require little (annual) maintenance. Even though the initial cost of installation may be quite costly, the potential for saving on energy bills, in the long run, is significant.
