Latest Technology Bringing Forth Super-efficient Cooling & Heating Technology to HVAC Systems

VRF / VRV is the latest in technology bringing forth super-efficient cooling and heating technology to HVAC systems. A reason for the increase in efficiency is that the refrigerant cooling/heating coil is in the space. VRF/VRV can be used in a home (using a split-ductless system) or in large commercial buildings with many zones. They can even cool some zones while heating others simultaneously! VRF/VRV allows for precision heating or cooling. That is why they are popular with hotels, dormitories, hospitals, office buildings, and apartment buildings. Because the refrigerant is Read More...

R-407A in Low and Medium Temperature Refrigeration

R-407A is a proven replacement for R-22 in supermarket systems. It can be used in both medium temperature and low temperature direct expansion systems. Medium Temperature Performance R-407A capacity relative to R-22 will be slightly higher, while the energy efficiency will be slightly lower. R-407A is higher in energy efficiency than R-404A. The table below shows the evaporator performance of R-407A and R-404A relative to R-22. The data is derived from laboratory tests and calorimeter data. Condition R-22 R-407A R-404A 20°F Evaporator Temp COP (Evap) 100% 97% 90% 105°F Condenser Temp Capacity 100% 102% 100% 20°F Read More...
