Daikin VRV Revolution: When it comes to contemporary heating, ventilation, and air conditioning (HVAC) systems in commercial or large residential spaces, the revolutionary name, giving confidence to professionals as well as customers, is Daikin VRV. That's simply something we'd never seen before, and now here it is available in this sophisticated yet very effective means of customizing comfort for all the zones in a building. And, if the name is familiar, but you can’t quite wrap your head around what it entails, this article will introduce you to the basics of Daikin’s Variable Refrigerant Volume system. 

What is Daikin VRV Technology? 

VRV is the abbreviation of Variable Refrigerant Volume. It’s a technology that Daikin created and trademarked in the early 1980s. It’s also called VRF (Variable Refrigerant Flow) by other manufacturers, but it is the same system. 

Fundamentally, a Daikin VRV system is a commercial world-renowned heating, ventilation, and air conditioning (HVAC) technology. It consists of one outdoor unit (or a multi-split system with many indoor units) connected to multiple indoor units through a network of refrigerant lines. It is capable of dynamically adjusting the volume of refrigerant that is provided to all zones, resulting in perfect independent temperature and humidity control throughout the system. 

How Does the VRV System Work? 

The secret of the VRV system lies in that it utilizes an inverter-driven compressor. While conventional compressors can either be on full power or off (that’s how all the issues with stop-start occur, as it consumes a lot of energy), the inverter compressor in VRV systems has variable speed. 

Demand Sensing - Individual room units sense the actual room temperature and switch from heating to cooling and vice versa as demand changes. 

Volume Setting: The indoor unit issues this demand signal to the outdoor unit. 

Vari-flow: The capacity, the inverter compressor of the outdoor unit varies and modulates by varying the amount of refrigerant flowing through pipes connecting chambers of the system. 

Accurate Delivery: Only the necessary amount of refrigerant is provided to precisely maintain the set temperature - no undercooling or overcooling of the room. 

This continual modulation of capacity, which is commonly coupled with technologies (such as Daikin’s VRT: Variable Refrigerant Temperature) to further maintain peak performance, means the system always runs at maximum efficiency and over time this can result in significant energy savings. 

Key Benefits for Your Building 

There’s a reason businesses like offices, hotels, hospitals among other commercial buildings strongly favor the VRV system. The advantages run deeper than simple cooling of a room: 

Unrivaled Energy Efficiency 

By matching the unit to the building at precise capacity, use of inverter technology eliminates the waste of frequently cycling on and off and full-blast operation. This equates directly to less cents out of your pocket and a smaller carbon footprint, being the environmentally responsible choice. 

Attention to Comfort with Zoning 

It could be the number one differentiator. All rooms or zones attached to the same system can be controlled separately. That means that one office can be tuned to a cooler temperature while the adjacent conference room, in which more people generate heat, gets the maximum amount of cooling. In fact, some VRV models can offer cooling in one zone and heating in another at the same time – making for happy campers! 

Design and Installation Flexibility 

Multiple style selection. For various room styles and designs, a large selection of indoor units — wall mount, ceiling cassette, and concealed ducted type AC can be adopted to match the needs. The system includes small-diameter refrigerant piping instead of large ductwork for easier installation and saving precious ceiling or wall space. One outdoor unit can be connected to multiple indoor units, minimizing the external space required for installation. 

Quiet Operation 

As the compressors are placed in the outdoor unit, there are hardly any potential sources of noise indoors, so with indoor units operating at an extremely quiet level it guarantees an undisturbed workspace whether in a highly active office, hotel or home. 

Conclusion 

Daikin VRV life systems are the industry's first air-cooled system that delivers all the benefits of traditional VRV in a smarter, smaller, lighter package. They have an unmatched ability to provide individual comfort control and the flexibility in design, ensuring that each room is equipped with superior conditioning. Daikin VRV is a system that offers energy efficiency, flexibility and a customized air conditioning solution that supports you to have greener options for HVACR with the utilization of an optimized refrigerant.
