Chiller plant design manual

Tracer® Chiller Plant Control, p. 60 Trane Design Assist™, p. 62 Repeatable, simple yet flexible Tracer® chiller plant controls provide sequencing and advanced optimization strategies to reduce energy use, with intuitive dashboards that explain what the system is doing and why. Pump, valve and cooling tower controls.

Main Terminal Chiller Plant Study Page 5 of 15 operated so that the South cooling towers operate in conjunction with CH-1, 3 and 4 and the North cooling towers operate with CH The chilled water piping is currently configured in a very non-traditional layout. The largest chiller is currently identified as CH-.

The design of a chiller plant can greatly impact chiller performance. A popular system is to place the evaporators in series with the chilled water flowing from one evaporator to the next as shown in Figure 2. The system puts all of the condenser water through the condenser of the lag chiller (chiller producing the coldest. 4. The DeltaPValve® has the proven track record to back up the design approaches recommended in this manual. DO NOT USE this manual as a guide for the application of any other valves. 5. A number of articles are listed in the back of this manual. These reference highlight issues and expenses related to low delta T operations. of a chiller plant, providing optimized occupant comfort while helping to reduce energy usage and operating costs. The system includes a dedicated chiller plant controller and an extensive library of control programs, graphics, and energy dashboards that can be easily customized to meet the design and specifications of any chiller plant.

This manual examines chilled-water-system components, configurations, options, and control strategies. The goal is to provide system designers with options they can use to satisfy the building owners’ desires, but this manual is not intended to be a complete chiller-system design manual. Chiller Plant Design Guide initially discusses the components used in a chilled water system. It reviews various chiller plant designs explaining their operation, strengths and weaknesses. The purpose of this manual is to discuss various piping and control strategies commonly used with chilled water systems including variable flow pumping systems. Using This Guide This Guide initially discusses the components used in a chilled water system. It then reviews various chiller plant designs explaining their operation, strengths and weaknesses.
