Program Objective

The objective is to develop the participant's ability to recognize cost saving measures in HVAC equipment/operation and then to implement the right changes to effect these savings. Measures to be explored include low up-front-cost O&M procedures and fast payback equipment modification projects.

Additional objectives include showing the participants the latest on measurement instrumentation/techniques for measuring and improving HVAC efficiency.

An additional objective is to update participants on the status of existing and new refrigerants including handling, recovery and the purchase/retrofit of new equipment.

Resource Materials

Each participant will receive a computer program on a floppy disk in a user-friendly format for IBM compatible computers. This program will evaluate the performance of a chiller of other refrigeration device. Participants can easily study effect of changes such as changing condensing or evaporating conditions, load, etc. The program determines system efficiency for all common refrigerants. THE VALUE OF THIS COMPUTER PROGRAM IS $100 IF BOUGHT SEPARATELY FROM BEI!

Each participant will be provided a textbook which will serve as a valuable resource guide after attending the course. This book of more than 200 pages contains numerous charts, illustrations, and background writing to make HVAC savings easy to master. THE VALUE OF THIS TEXTBOOK IS $25 IF BOUGHT SEPARATELY FROM BEI.

Upcoming Boiler Efficiency Institute, LLC Courses

(HVAC Courses $695 each) These are held May - September. South Carolina courses are available to state residents only and are offered at a reduced rate.
