For a long time I thought VRF systems had to do with radios or TVs, and it sounds too much care about VHS or boombox frequency.
I did not feel what VRF even stood for until recently. I had fun little ideas care about truly rabid ferrets or vicious rabbits farting. In reality VRF absolutely stands for variable refrigerant flow plus it has to do with Heating, Ventilation, plus A/C, but these systems provide off extremely efficient heating plus air in commercial buildings. What the plan does is change the amount of refrigerant flowing through the system; Different areas of a large building can have heating while others have cooling. It is sort of care about Heating, Ventilation, plus A/C zone control, however separate from the numerous units. It is just a plan of pipes stretched over a large space plus all altered by a single truly powerful system. The reason for it is that heating plus air demands in large spaces change throughout the morning, then you have people coming in plus out adding plus taking away heat. The sun changes position throughout the morning. There is also lighting plus office equipment that emit heat… A VRF plan can handle the changes plus alters its workload in accordance to them. An section is never too warm or too cold, no matter what the internal plus external factors are. The equipment is so efficient that it can even take the excess heat from a single section plus distribute it to another location that truly needs it. I feel that it can be added onto as well. You can add more indoor units that link to the same outdoor unit.
