Got a question for the Daikin guys out there... how does your VRV system maintain room setpoint?
My understanding is that indoor fan coil units (all of them) are basically constant volume. Yes, you can change the speed on the controller if you want, but you would have to do that manually. I'm also told that the EEV on the indoor units tries to maintain the same superheat on the suction line on the outlet of the various fan coils. According to Daikin service manuals, the outdoor units revs compressors up and down trying to maintain the same evaporator pressure. So, I'm confused... how can you maintain the same saturated suction, fan speed and superheat all the time? How does the system change/react on change in room temp?
Can somebody please help me connect the dots?
