The compressor is the heart of the system and is located within the Outdoor Unit which can be an air or water-cooled VRF system. The Outdoor Unit will serve multiple indoor units with each VRF manufacture limiting...
Calculating Cooling Load
What exactly determines the size of the heating and air conditioning system and the required amount of air (CFM) to be delivered to the space? in this article we'll show you what goes into calculating the cooling...
Is your building too dry inside, thereby providing life sustaining low humidity levels for the Coronavirus or other viruses to live?
Researchers at Yale identify low Relative Humidity as a potential culprit in sustaining the...
Refrigerant Recovery Speed
Using the 80/20 rule, where we assume that 80% of the refrigerant recovered will be in vapor form and 20% will be recovered in liquid, we have created the following chart....
Manufactures VRF Piping Layout Drawings
The VRF Piping Layout is highly engineered by the VRF manufactures software to design the pipe sizes to meet the capacities and conditions required, including ASHRAE 15. The pipe sizes are affected by capacity, pipe lengths and...
