Here we go again. I keep reading threads about CO2 and all of the mis-information out there on the subject of CO2. This is not a new refrigerant. If you use it as a low temperature secondary fluid the pressures are around 220-240 PSIG operating pressure. If you use it as a secondary medium temp fluid your operatng pressures are around 400-440 PSIG. AND dont forget its .50cents a lb. There are about 25 system using CO2 as a secondary low temp fluid in the USA. There is one Cascade system using low temp CO2/glycol medium tmep. And 2 systmes located in the south that use CO2 as a medium and low temp refrgerant None of these systems are used in transcritical operation. If you are really intrested in how these systems work, HP will be conducting training classes around the country. I will post all up comming classes for those who want to come. It is not a Sales class. See the infor on the upcomming classes in Atlanta in March. My opinon is Ammiona is also a future option for supermarkets. I start taking my first Ammiona class on Monday.
Hill Phoenix is having an upcoming Regional Training Program in Atlanta GA. This class is geared to the service tech and the installers, our goal is to teach in an open format all things secondary (glycol and CO2). The training is open to anyone intrested in learning this new technology. The classes are as follows:
March 16th 8:00-5:00 Sencondary glycol installation startup and troubleshooting. Great class for mech and tech
March 17th 8:00 - 12:00 Geroge Fischer pipe (Plastic refrigeration pipe glycol only) This class will certifiy you in the installation of GF piping.
March 17th 1:00 - 5:00 Compact Chiller Modules. Secondary system the use about 50 - 80 lb of HFC for the entire mediuim temp rack (Very Kool)
March 18th 8:00 - 1:00 CO2 installlation, Startup, and Troubleshooting.
