Due to the increasing progress of science in the field of mechanical installations, especially air conditioning, the best choice now for managers and investors is VRF or Variable Refrigerant Flow systems, which due to their good performance, low cost, ease and speed. In installation, they are a good option for apartments, hotels, banks, hospitals, companies, shopping malls and so on.
These air conditioners are actually very useful for controlling the load and changing it in an instant, and its design is based on digital inverter technology. A Pulse Modulating Valve valve in each unit controls the exact amount of refrigerant that must be sent to that environment. In fact, VRFs are advanced types of multi-split systems without channels that allow more indoor units to be connected to each outdoor unit and provide additional features such as simultaneous heating and cooling, heat recovery and the possibility of piping over long distances. Providing heating and cooling by a fully integrated system with the control system increases the coefficient of performance of COP heating and EER cooling. In this system, like the conventional ventilation system, there are not many ducts, or like the multi-split system, there is no need for piping to each separate unit, and only parallel refrigeration piping is done, one of which is the refrigerant return line and the other.
The following are some of the reasons why consulting engineers are so widely used to use these systems:
Feel more comfortable in people
Most of its COP is in cooling and heating and its high performance
No need for many channels
Possibility of piping at long and convenient distances in high-rise projects
Possibility of installing indoor units of different types of shortcomings, wall, ceiling, floor and…
Central controller and use of environmentally friendly R 410 a refrigerant
No need for engine room and maintenance technician
Simultaneous heating and cooling
No need to consume water
