VRF Systems and Industries

What is Variable Refrigerant Flow?

Variable Refrigerant Flow (VRF) or Variable Refrigerant Volume (VRV) is a ductless HVAC system that can run at a high capacity on a large scale. HVAC consultants design HVAC systems depending on the project requirements in an industrial project. 

VRF systems use a refrigerant as a heating and cooling medium. The system can be with one or multiple condensing units. 

When the HVAC consultants are a part of the design from the start under the "Total Design" philosophy, the resultant design is optimised. 

Advantages of VRF 

The MEP consultants consider the multiple advantages of the VRF system. Some of them are as follows:

1. Simultaneous heating and cooling or various parts of the industry.
2. Occupants can customise the temperature.
3. Multiple-speed compressor settings.
4. Customisable as per space availability. 
5. Less noisy when compared with the old technology HVAC systems.
6. Easy installation.
7. Energy-efficient.
8. Better air quality as compared to the conventional HVAC systems.
9. Modular and expansion is easy.
10. Maintenance and operation is easy.
    
    

Types of VRF

Typically, the VRF systems are of the following types. The industrial HVAC consultant chooses for one of them.

1. Cooling Only VRF System: This system keeps the place cool by removing heat from the area. Heating is not a part of this system. 
2. Heating or Cooling VRF: This is a central climate control equipment. It provides a choice between heating and cooling. It has a furnace and an air conditioner. The user can set it for heating or cooling.
3. Heating and Cooling VRF System: This offers cooling and heating simultaneously and is useful in a large area. The setting can be kept different for different areas.
   
   

To conclude, HVAC consultants decide on the VRF system based on the project requirements, energy efficiency and cost. Additionally, the consultant has to consider the maintenance and operational costs.

Subsequently, the HVAC consultant has to design a VRF system based on the requirements of the project, equipment available, local weather conditions and budget.
