Variable Refrigerant Flow (VRF) Systems

All VRF systems provide energy savings by varying compressor speed and matching the output of the system as closely as possible to the load. In addition, VRF systems do not experience the same energy losses as systems that move conditioned air through ductwork. However, differences in design the available in

One of the Fundamental Series - Trane

The resulting hot, high-pressure refrigerant vapor (C) enters the condenser where heat is transferred to ambient air, which is at a lower temperature than the refrigerant. Inside the condenser, the refrigerant vapor condenses into a liquid and is subcooled. This liquid refrigerant (D) then flows from the condenser to the expansion device.

The next step is to account for the pressure drop attrib-utable to fittings in each refrigerant line. For simplifica-tion, counting 90˚ elbows is sufficient for estimating line sizes. For each refrigerant line, and from plans or schematics, count the number of elbows in each refrigerant line and record the number on Line 4 of Table V.
