What is a VRV System?

Updated: Sep 11, 2023

VRV systems or variable refrigerant volume is a technology called HVAC which is basically utilized as a medium for heating and cooling. The Daikin Industries Ltd back in the year 1982 invented the technology which uses ductless styled mini splits. Such kind of a refrigerant is used by various air conditioners in their outdoor condensing units. They help circulate the air inside the building via more than one indoor unit installed at different points. You can install the VIRV systems in your large rooms or commercial places. You need to install some ducts on your roof or ceiling, and you will get the utmost comfort along with your preferred temperature from these ducts.

Basic Working of a VRV Systems VRV systems comprise an air conditioner inverter which is installed in them. This helps in adding the DC inverted with the compressor unit. This aids in supporting a continuously changing the speed of the motor which will generate fresh and cool air flow in your rooms. So, when the machine operates at different speeds, these units work using a basic rate which not just helps saving energy but also save your overall electric consumption bill. This heat recovery technology of the VRV system will help you to regulate the heat or temperature of your rooms. The load of the compressor is benefitted with the heat recovery taking place internally. You can save up to 55% of your energy consumption by installing VRV system. This has been proven by the experts that if you want to have a better grip over the overall indoor temperature of an entire home or office buildings then you must install the VIRV systems in your home. Main format of Use of VRV systems The VRV systems come in two different formats and these are the double pipe or three pipe-based systems. HR or heat recovery systems possess competencies for heating specific zones and also cooing some other zones. This can be made possible using three pipes in this design. However, not all brands support heating and cooling at the same time simultaneously. Reputed brands such as Daikin are using functional VRV systems for their customers. Units which do not use a three-point system perform the operations using a two pipe system and a BC or branch circuit controlled where evaporator zones are created in separate indoor spaces. So, the heat which is extracted from one single zone can be used for cooling another zone. So, the heating unit in a VRV system here is using a condenser and offers a sub-cooled liquid in a line and is used this for cooling. This is a great cost saver initially as it offers a zoned control of thermal units in a building and increases energy efficiency as well. So, since the community is heating some are cooling and this can reduce energy consumption. VRF or VRV – are they same? Often, we tend to get confused between a VRV system and a VRF. You must understand that they are two separate terms used on the basis of the same HVAC based technology.  VRV or variable refrigerant volume and it is a trademark patent of Daikin. VRF or variable refrigerant flow is used by any other dealer or company who specializes in the HVAC systems. So basically, they are two varied kinds of names given to the same options made by different manufacturers. Research must be made for any professional who is venturing out in this field as an expert air conditioner repair or dealer. Remember that the customer is spending money based on the guidance of the consultant and then a thorough understanding of the VRV system is going to be immensely helpful.
