If piping or indoor unit fan coil locations need to be revised, the VRV Xpress will recalculate pipe sizes and refrigerant charge automatically. If a room has more than one VRV system serving it thus more than one refrigerant circuit

R32 Common Questions - AIRAH
www.airah.org.auConsequently, if an accidental release of R32 refrigerant occurs from a cylinder or piping, the velocity will be too high to ignite near the release point and the concentration will be too low where the velocity becomes low enough. So, ignition of R32 is difficult even if it is attempted intentionally.
REFRIGERANT PIPING INTRODUCTION - RSES
www.rses.orgREFRIGERANT PIPING By: Cecil R. Visger, Past International Piping INTRODUCTION In recent years, manufacturers of condensing units have more and more gone to motor-compressor units and direct-drive compressors, which means that the compressors are turning at motor speeds. These relatively high-speed compressors
STUDYING THE VARIABLE REFRIGERANT VOLUME (VRV) …
inis.iaea.orgVariable Refrigerant Volume (VRV) system is a multi-split type air conditioner. VRV has also been referred as Variable Refrigerant Flow (VRF) that uses variable refrigerant flow control to provide customers with the ability to maintain individual zone control in each room and floor of a building. The compressor unit is

www.trane.comThe units described in this manual use R410A refrigerant which operates at 50 to 70% higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are painted with "pink" color to indicate the type of refrigerant and may contain a "dip" tube to allow for charging of liquid refrigerant into the system. For
