Improvement of the cooling heating changeover Continuous operation during oil recovery Sound level reduction of branch selector unit No system interruption in mode changeover With most VRF systems when changing an indoor unit from cooling to heating the heating operation for the full system is shut down The system pressure must equalize in the hot gas line which causes disruption to all units in heating The heating is then started for the full system and each indoor unit has to go through a hot start the indoor unit coil has to be at approximately 93 F before the fan starts to avoid cold drafts This sequence of operation can take approximately 10 minutes With the new branch selector unit BSVQ_P only the indoor units changing trom cooling to heating will shut down and only those will go through a hot start causing no system disruption and only six minutes of downtime for the indoor unit changing operation mode The changeover time can be shortened depending on the pipe length from the branch selector unit to indoor unit by simply reprogramming the indoor unit range 3 10 minutes Traditional VRF Model EV EV CD CD mr ll M Wy C gt H II C gt H j Om O lt lam jo lt 4 l l I M MA M Oe De EV EV cD C I I I Fanor i AA 4 FAN gi eis Heating interruption 10min No system memunton Iml EV EV EV EV CD CD ir CD 6D I I I I I S IA S
