Overview of Chiller Compressors
This online engineering PDH course provides comprehensive information on the chiller compressors. It addresses the key issues pertaining to the chiller compressor selection and their applications. The practical considerations and assessment criterion are also discussed in brief.
In HVAC industry, the refrigeration machine that produces chilled water is referred to as a "chiller". The majority of installations operating worldwide are based on the vapor compression chillers that use mechanical energy in the form of electric motor to drive the cooling cycle. The vapor compression chiller packages are generally classified by 4 types of compressors namely centrifugal, reciprocating, screw and scroll.
This 4 PDH online course is applicable to HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Operating principle of reciprocating, screw, centrifugal and scroll compressors
- Key advantages, disadvantages, limitations and drawbacks of various refrigeration compressors
- Efficiency ratings of various chiller options on peak load and part load
- Factors affecting the efficiency of chiller compressors
- Types of refrigerants used/recommended
- Heat rejection options - air cooled vs. water cooled chillers
- Reliability, maintenance, field serviceability of various chiller options
- ARI standard 550/590 performance standard for defining part load performance ratings - IPLV vs. NPLV
- Importance of peak load and part load analysis in determining the overall capacity and number of chillers
