Q:
What are some of the applications you have used refrigeration and air conditioning compressors for?
57 answers
Answers:
Air conditioning engineers broadly divide air conditioning applications into comfort and process. Comfort applications aim to provide a building indoor environment that remains relatively constant in a range preferred by humans despite changes in external weather conditions or in internal heat loads. Air conditioning makes deep plan buildings feasible, for otherwise they would have to be built narrower or with light wells so that inner spaces receive sufficient outdoor air via natural ventilation. Air conditioning also allows buildings to be taller since wind speed increases significantly with altitude making natural ventilation impractical for very tall buildings. Comfort applications for various building types are quite different.

I have encountered various types of air compressor in ships where they supply high pressure and low pressure ringmains and control and servo air to pneumatic control systems. I have selected and applied most types of refrigeration compressor from 1/2 HP up to 200 HP in a wide variety of applications including cacade and 2 stage systems, cold rooms, dx air conditioning, water/fluid chilling, all at temperatures ranging from -70ºC to +30ºC and with all CFC, HCFC, HFC and HC refrigerants.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of refrigeration and air conditioning compressors?
18 answers
Answers:
Yes, if the compressor supplier buys valves from a source other than Selco he runs the risk of having its unit fail for any assembly detail taken not into consideration. If the compressor fails so will the unit.
~Benjamin B, International Business, S.B.Campo, Brazil
