Can the chiller operate at partial load conditions and respond to changes in temperature and flow?

Yes. The chiller features a PID control in the PLC that looks at inlet hot water temperature, outlet chilled water temperature, and internal refrigerant temperature. It then evaluates the optimal time to open the hot water valve for regeneration of the desiccant during heating.

If chilled water outlet temperatures are too low, it will also turn off cooling water flow to the modules that are adsorbing, which almost immediately stops the cooling process. When chilled water temperatures rise, it will again turn on the cooling water flow.

During any mode of operation, the external pumps will see constant flow. There is no need for additional valves or special pump controls.

The chiller has 7 steps of capacity control capable of turning down to potentially 15% of its nominal rating.

The chiller assumes constant water flows, but it will respond to variable flow rates without hurting the machine. It is best if flow changes are made gradually so as to allow the chiller time to respond.
