Title: FLUID PRESSURE CALIBRATION IN CLIMATE CONTROL SYSTEM
Abstract:
A method for selecting a fluid pressure of a fluid supplied to a plurality of terminal units in a climate control system includes adjusting the fluid pressure over a range over fluid pressures; determining a terminal unit efficiency for each terminal unit over the range of fluid pressures; determining a range of combined terminal unit efficiencies over the range of fluid pressures; identifying a range of bottom terminal unit efficiencies over the range of fluid pressures; and selecting a selected fluid pressure at which (i) a combined terminal unit efficiency is within a first threshold of a combined terminal unit efficiency limit and/or (ii) a bottom terminal unit efficiency is within a second threshold of a bottom terminal unit efficiency limit.
