Actually, VRV and VRF are two different terms for the same HVAC technology. Based on Inverter technology compressors, the first VRV HVAC systems were invented by Daikin during the early 1980's. As a technology leader in the HVAC industry, Daikin registered the VRV term (which stands for Variable Refrigerant Volume 1) as an official trademark.

Strategies to control the spread of these diseases are outlined in another guideline. 3. The spread of airborne infectious diseases via droplet nuclei is a form of indirect transmission. 34 Droplet nuclei are the residuals of droplets that, when suspended in air, subsequently dry and produce particles ranging in size from 1–5 μm.

An air conditioner’s evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. That is, it’s where the cold air comes from. The evaporator coil is located inside or near the air handler where the blower fan is. Evaporator coils are made from copper, steel, or aluminum because these
With the indoor and outdoor design conditions selected, the design process then requires the calculation of the summer heat gains and winter heat losses. To maintain satisfactory indoor conditions, air supply and extract flow rates are determined based on a number of considerations, including the need to offset these gains and losses.
