It is another thing to deliberately undersize and cut every corner on installation in order to be “competitive”. It is one thing to design a job as economically as possible and yet correctly. Too many systems are designed to “meet a competitive situation”. Dehydration through deep vacuum, acid removing dryers, and filters can help any system, but high discharge temperature, caused by an improperly designed system, is virtually impossible to correct. The competent service technician can do much to minimize these reactions. We want a chemically stable and trouble-free system. The last thing we want a refrigeration system to do is create chemical reactions. There is plenty of pressure and heat, and at times, there is more than he or she knows what to do with. He or she has reactive materials in abundance - refrigerant, oil, cellulose, copper, oxygen, moisture, acid, etc. The refrigeration service and installation person has a great chemical reactor at his/her disposal. Often, the chemist must supply great quantities of heat to accomplish the reaction. He/she uses equipment to search for better ways to make a reaction proceed swiftly and more completely. Heat, pressure, and reactive chemicals are the tools of the chemist to create reactions.
