A new kind of HVAC system is emerging in the Indian commercial building space conditioning market. This new system utilizes variable refrigerant flow (VRF) or variable refrigerant volume (VRV) technology and uses an evolved heat-pump technology with heat recovery systems and sub-cooling built in, which increases effectiveness and efficiency. The use of this evolved technology makes these systems a good option for certain kinds of commercial construction projects that require high levels of flexibility when it comes to occupant comfort or for retrofit projects.
VRF/VRV systems require slightly different considerations for completion of the insulation portion of the project, and include challenges that mechanical insulation contractors will have to overcome. There are many considerations that are important when designing the project, selecting the insulation materials and methods, estimating the project, buying the materials, and planning labor requirements.
