Know about the VRF HVAC

The HVAC controlling system is used for heating and cooling purpose with the help of dampers, fitted in the duct to redirect and adjust the air to particular areas.

This gives the facility to generate customized temperature for a definite zone which will automatically increase the efficiency and convenience.

Facility Management also provides services for variable refrigerant flow system with the motive to offer better efficiency with optimum utilization.

The VRF HVAC technology has been widely used by facility services providers to deliver features such as efficient use of energy, installation ease, and control over temperature to their customers.

Countries like China, Europe, Japan is already using VRF systems for efficient energy utilization, but now from the last 5 to 10 years, this technology has become popular in the US also.

VRF HVAC is becoming the topmost choice of users over conventional air conditioning systems because of its outdoor condenser and indoor fan coil units.

It uses several small air handlers to pump out the air. All that handlers can be controlled individually and can be piped again to one system. Its name VRf points to its capability to manage the quantity of refrigerant passing to each of these tiny handlers. This eliminates the need of one huge and noisy unit for pumping out the air to whole space.

The VRF is not only used for cooling purpose but it also has the ability to provide heat, and even both features can be used simultaneously as per the need of the area.

It detects the current conditions and its variable speed compressors works according to it to achieve the efficiency of the energy.

This technology has a vast domain of applications, it can be used in medical facilities as well as at office premises also.

VRF is able to provide the full range variable capacity of delivering a specific amount of conditioning according to the zone demand.

Energy usage fluctuations are one of the major challenge faced by commercial buildings. It is because of the absence of a variable capacity compressor that helps to achieve temperature satisfaction through the traditional system.

VRF is majorly concerned with the load conditions.

Integrated controls and sensors can be used with VRF systems for measuring the load requirement as per the individual cooling and heating zones. The compressor is said to be the heart of VRF that manage its speed to sustain the desired temperature.

Why VRF attracts the facility managers?

Installation of VRF  offers multiple benefits to the facility managers.

The target of managers is to achieve lower utility bills, and VRF system helps them to achieve this by giving leverage to increase energy efficiency. It provides almost 25%  increment in the performance of energy as compared to a conventional HVAC system.

It becomes possible with the utilization of inverter compressor technology used with least ductwork demand.

Originally, this technology was used to deliver flexibility in design but now it also provides excellent control to give personalized comfort to its users.

It offers the following facilities to its occupants:

Energy Efficient: VRF HVAC system is designed in such a way that it to deliver a specific amount of cooling and heating needed for the current condition which leads to consuming less energy. It takes the heat from the cooling process and then reuses it the region where heat is required.

Avoid Noise: VRF HVAC system provides smooth functioning because it uses small indoor air handlers that are quiet than common systems and its noise causing condensing component is generally fixed externally.

Ability to provide both heating and cooling facility simultaneously: The VRF system is smart enough to capture the heat at the time of the cooling process and reuse it at the time of the heating process and both the operations can be performed simultaneously.

Consistent service: VRF system first analyses the precise requirement of a particular zone and then send the refrigerant according to it because of which the humidity of each zone can be controlled in a consistent manner.

Downtime is least: There is less wear and tear on the components of because VRF HVAC system because it runs only when it is required and in partial load conditions. 696

Independent air handlers: In VRF HVAC system if something goes wrong with any one of the handler then it will not affect the working of others.

Needs less space: There is no need for ducts in VRF system and its indoor handlers are also small that’s why it doesn’t require large space.

Advanced Controls: IT can be controlled via mobile phones which allows a user to control the temperature of each zone through a just single touch on the mobile screen. It has built-in controls that eliminate the need for purchasing the costly building management software.

Customer’s Experience: There is a college named as Johnson Country Community College situated in Overland Park. They have recently inaugurated a new academic building on their campus. To achieve 100 % renewable energy at the campus by 2050, they have decided to use VRF systems. This VRF system is installed at three different spaces of the college premises and definitely, the output will be in their favor very soon.

VRF technology is rapidly becoming the choice of users. Everyone wants to utilize the benefits of VRF system even facility managers are trying to use it so that they can provide energy-efficient solutions to their customers and ultimate motive is to generate lower monthly bills with the help of efficient utilization of energy.
