Optimal Performance

Regardless of the system level being designed, the unit controls become critical not just in making every level operate reliably but in facilitating optimal performance. UCP2 provides more capability and more intelligence to make this operation/ optimization possible:

Chiller Level

•Factory mounted water temperature sensors

•Variable speed drive for those installations in which the chiller is operating at part load conditions a significant percentage of the time and where cold condenser water is available.

•Hot gas bypass for those process installations where the chiller will need to respond quickly to sudden load increases.

•ASHRAE Guideline 3 Report incorporated into the Chiller Report and Printer Report. Guideline 3 aids operators in managing refrigerant assets.

Chiller Plant Level

•Heat recovery — to take advantage of waste heat from the chiller for heating applications.

•Heat pump — for those applications in which heating is the primary mission of the chiller and cooling is a waste product (requiring an endless source of heat such as a well or lake water).

•Free-cooling — for use in those parts of the country where cold condenser water is available to eliminate the need to operate the compressor.

•Variable flow — for applications where either the condenser water or the system water flows must vary.

•Ice-making — for demand charge avoidance or for additional capacity needs and where no cooling requirements exist for considerable periods of time.

•Low condenser gpm for chiller plant optimization.

•Cooling tower reset based on head pressure for tower optimization.

•Low evaporator fluid temperature for process applications.

•kW demand limiting for those installations where avoidance of demand charges is more critical than maintaining capacity.

•Chilled water reset (based on return water temperatures or ambient temperature or based on a 4-20 mA signal) for those installations where energy savings is more critical than maintaining design leaving chilled water temperature at part loads.

Applied Systems

•Low evaporator fluid temperature for cold air/humidity control applications.

•Variable fluid flow where evaporator flow is modulated by a device outside the control of the chiller or the chiller plant.
