VRF systems by Mitsubishi Electric India are a range of sustainable and cost-effective air conditioning solutions that provide efficient cooling and are well-suited for residential as well as commercial applications.
VRF (Variable Refrigerant Flow) is a technology that controls the amount of refrigerant needed by the indoor units of air conditioning systems. This mechanism of individually controlling several electrical units, like ACs located throughout the building, makes the technology of VRF ideal for appliances with varying loads. Moreover, to the required comfort provided and the design flexibility, the VRF system also provides energy savings and cost-effective installations.
Mitsubishi Electric India offers a wide range of VRF systems for varied applications. In general, VRF systems can be categorised based on the number and type of compressors they use.
Single Variable Speed Compressor
This system has a high-capacity scroll compressor. The same compressor starts and runs when there is a demand. When the compressor fails, no redundancy is available.
Variable Speed & Fixed Speed Compressor
This is a two-compressor system, where the inverter-driven compressor starts and ramps up until maximum capacity is reached. At this time, the inverter-driven compressor ramps down and fixed speed compressor starts.
Multiple Variable Speed Compressors
This system provides the major advantages of a VRF system. A system, with multiple variable speed compressors, provides greater backup capabilities. In case of one compressor failure, the system continues to operate at 67% of its initial capacity and comfort will be maintained in the space until the failed compressor is replaced.
Mitsubishi Electric India’s VRF systems are counted among the most popular types of air conditioning systems available today, thanks to the numerous advantages they come with:
Better Control
A VRF system provides controlled heating and cooling supply without swings in the room temperature. Unlike conventional systems, in a VRF system, the compressor speed can be varied. It means the compressor doesn’t switch on or off, rather operates on for longer periods. The indoor fan coil is supplied with the refrigerant flow and once the set point is achieved, the refrigerant flow is adjusted to keep the room temperature stable. The indoor unit fan speeds can be modified, in addition to having different set points, providing additional comfort in the room.
Flexibility
A major advantage of the VRF system is the flexibility provided by varied product offerings. There is a variety of fan coils in different shapes and sizes to suit any application.
People who are purchasing VRF systems for the first time should keep in mind that all systems don’t have the same piping capabilities; however, an extended piping capability may maximise the application flexibility.
Cost-Effective
Unlike traditional systems which require large pipes, pumps, and boilers, the installation of a VRF system is cost-effective. The outdoor units are not only lightweight but also small, saving on construction and installation costs.
Saves Energy
VRF systems save energy by varying the speed of the compressor and matching the system output to the load as closely as possible. Moreover, the energy losses incurred by the VRF systems are not the same as the energy losses by the systems that move the conditioned air through ducts do, however, the difference in the design of the outdoor units may affect the degree of efficiency achieved.
Compact Size
The compact size of the outdoor unit limits the footprints of the VRF systems allowing the installation of applications in limited spaces, such as on crowded rooftops or in tight mechanical closets.
