Re: [EnergyPlus_Support] Can simulate the energy consumption of VRVsystem

[li yuandan <liyuandan2000@xxxxxxxxx>]

Thanks for your reply.
You are correct, the VRV system is a air-to-air DX
system. However,it is different from other
conventional DX system.
Generally,VRV system uses 2 compressor. One constant
speed compressor, the other is a variable-speed
compressor. VRV is also a multi-dx system. The most
common configuration is one outdoor unit (with 2
compressors) serves about 6,8 or much more indoor
units.
