Scott Process Chillers Cooling Systems - Scott Process

A chiller is a compressor based cooling system that is similar to an air conditioner except it cools and controls the temperature of a liquid instead of air. The other main components to a chiller are a temperature controller, a recirculating pump and a reservoir. Operation and setup is simple. Fill the reservoir with fluid to be recirculated ...

Feb 10, 2020 CHILLERS Provide chiller packages with centrifugal compressors, or screw compressors, and water cooled condensers. Design the chiller plant with at least two chillers if the total capacity is more than 400 tons. Size one chiller for 1/3 of the load and the other chiller for 2/3 of the load. Include equipment KW/Ton and APLV values in a selection criteria.

Control sequences for chilled water systems - Consulting

Jan 20, 2012 The fan speed increases in response to the duct static pressure controller. As more air is moved across the cooling coil, a discharge controller begins to modulate the two-way chilled water valve open. As the chilled water valve begins to open, the chilled water differential pressure transmitter senses a drop in system pressure.

The Importance of Balancing Valves in Chilled Water ...

Jul 07, 2014 An unbalanced system cannot meet its specific cooling load; occupant comfort is therefore not achieved.

Using Control Valves To Optimize Cooling Water System ...

Mar 01, 1998 Note that even with a reduction in efficiency, power consumption is 6.5 kW before the control valve is installed and 3.5 kW afterward, a 46% energy reduction. At a treated water cost of $0.50/1000 gal. and energy cost of $0.05/kWh, annual savings total $7190. The figure assumes a 10% water loss from blowdown evaporation.

Chiller Energy Performance Parameters - HVAC GUIDELINES

Nov 26, 2021 It is a measure of chiller output (cooling) Divided by Input (Electric Power), Typical Valves are 2-4. COP= Cooling Effect Produce (KW)/ Power Input (KW) iKW/TR. It is a ratio of power input to compressor divided by tons of cooling produced, Lower the iKW/TR indicates higher efficiency. iKW/TR is used as a reference energy performance indicator.
