Chiller Plant Design Fundamentals

This is a primer course for advanced chiller plant design courses.  It covers the basics of the components such as pumps, piping, cooling towers etc. that are used to construct a chiller.

Overview of Constant Flow Chiller Plant Design

This course takes the design through the pros and cons of single chiller, parallel, series and series counterflow chiller plant design.  It compares operating cost as well as performance.

Overview of Variable Flow Chiller Plant Design

We will focus on primary/secondary and variable primary flow chiller plant design as influenced by ASHRAE Standard 90.1.  The material will cover pros and cons, design parameters and control issues.  Next we will discuss low delta T syndrome.  We will explain what it is and why it happens.  Then we will discuss how to correct it.

Courses will be continued upon on March 2, 2012 when Kent W. Peterson, ASHRAE Distinguished Lecturer presents technical session on Optimizing Central Chilled Water Systems.

Lunch & Presentation 12:00 pm – 1:30 pm – West Auditorium

Variable Refrigerant Flow Systems

The seminar will discuss the concept of multiple outdoor inverter driven compressors serving numerous indoor units while varying the refrigerant flow to meet individual zone requirements.   The concept has been successfully applied for more than 20 years in Europe and Asia and is rapidly gaining acceptance in North America. A typical VRF system uses ductless indoor units, but new applications can apply ducted indoor fan coils and even water cooled applications. A comparison will be made between simple chilled water systems and VRF hybrid applications. Finally, energy savings will be compared to more conventional systems.

Utah ASHRAE December 2^nd Tech Session/Lunch Meeting/Food Drive

Date:               Friday, December 2^nd, 2011

Location:        Intermountain Medical Center/Doty Family Education Center

5121 S. Cottonwood St. (100 West), Murray, UT

Time:              Technical Session (Classrooms 3, 4, and 5) – 9:30 am – 11:30 am

Lunch & Presentation (West Auditorium) – 12:00 pm – 1:30 pm

Presenter:      Dan Int-Hout, Chief Engineer – Krueger / ASHRAE Distinguished Lecturer

Technical Session 9:30 am – 11:30 am – Classrooms 3, 4, and 5

Topic #1 – “Basics of Air Distribution”

The basic physics of air distribution must be fully understood before one can properly select components for a project. This lecture will cover:

•           Understanding Terminology

•           ADPI (Air Diffusion Performance Index)

•           Proper Diffuser Selection

•           Common Product Groups

–    Well Mixed (Inductive) Air Distribution

–    Non Inductive Air Distribution

•           Value of Diffuser Selection

Topic #2 – Hospital Operating Room, Laboratory and Clean Room Air Distribution

Air flows in Hospital OR’s, laboratories and clean rooms are special cases, which require an understanding of the special needs in rooms with patients on an operating table, rooms with fume hoods, and in clean rooms, with much higher airflow rates.  All have different needs and require special considerations and equipment.

Lunch & Presentation 12:00 pm – 1:30 pm – West Auditorium

Methods of Effective Room Air Distribution

In order to meet the increased expectations of building occupants, designers must be aware of the conflicts between first cost economics, occupant productivity and life cycle costs. Buildings that do not meet the needs of the occupants often result in expensive redesign or worse, result in lawsuits against all parties involved. First, we need to understand the rules:

1.   LEED: 2009 is out, and many are not aware of some significant changes that have resulted in air distribution, IAQ and Comfort.

2.   Thermal Comfort: Determining optimum occupant comfort strategies. ASHRAE Standard 55 has been revised.

3.   Acoustics: Accurately predicting end use environments. A new classroom acoustical requirement needs to be understood.

4.   IAQ: The changing face of ASHRAE Standard 62.1, and upcoming developments.

I will briefly cover pros and cons of all 4 methods of air delivery:

-     Overhead air distribution

-     DV (Displacement Ventilation)

-     Underfloor Air Distribution (UFAD)

-     Chilled Beams and the DOAS Fan Box
