How to maintain the temperature inside my zone at 24 ° C (comfort) during the day using VRF systems ?. My model has several spaces. I am new to Openstudio and I do not know how to implement VRF systems. Thanks a lot for the help.

Hi @danlopch. Welcome to OpenStudio. And to UnmetHours. I can't really help you with the VRF question, but the Title of the question should be short and general like 'Help getting started with VRF on OpenStudio', and the tags should be the name of the software you are using 'openstudio' plus a keyword or two from your question, preferably one that already appears in the tags list. In this case, 'vrf' works.

The VRF with DOAS measure in the online BCL would be a good place to start. It will add VRF cassettes to all of your zones, and connect them to condensing units. This measure also creates air-loops to provide moderated temperature outside air to all spaces. It may be helpful to run this measure and look at the VRF section under the "HVAC Systems" tab to see how it's all set up.

The temperature setpoint is introduced in the cooling set point schedule not in the system. Once you assign a thermal zone to a system (VRF) it will try to maintain the setpoint you have entered in the schedules. I will recommend this video. It is for an older version of OS but the methodology is the same.
