This PDF file contains detailed diagrams, specifications, and tips for technicians and service providers.As you know, 404A was used in a variety of applications including vending machines. In the early 2010's there was a push from a variety of companies, including Coca-Cola, to switch their vending machines away from 404A and over to R-744 Carbon Dioxide. ... Suffice to say, a transcritical system and a high operating pressure system means two ...Take a voltage reading at the compressor’s terminals, and check measured amps with the manufacturer’s amp curve for the pressure readings and voltage taken. Make sure it is within the range (±5 percent) for the pressures and voltage recorded. Rule 5. Record the condensing and evaporating pressure of the system.

The application limits of R448A and R449A reach down to approximately -40°C only, due to the lower vapour pressure, while R404A and R507A reach down to -45°C. The upper limits are the same. The discharge gas temperature of R448A and R449A is up to 20 K higher than that of R404A, but lower than e.g. that of R407A and R407F.

refrigerant is 404a. tev is a bfse aa zp. charge is 1/2 lb past clear sight glass. liquid line is subcooled by suction gas. condenser coil is clean. discharge pressure is 300psig. Liquid line is 114 degrees at sight glass....97 degrees at tev inlet after subcooler. discharge temp 198 degrees.R290 refrigerant is used on a smaller scale in AC units and heat pumps in homes and in industrial refrigeration. In 2011, the EPA said that small amounts of propane could be used in stand-alone retail refrigerators and freezers. Comparing R-290 systems to R-22 and R-134a systems of the same size, R-290 systems use 40 percent less refrigerant.The difference with a R-744 application is that its operating temperatures can exceed the critical point temperature. Carbon Dioxide's critical temperature is just under eighty-eight degrees Fahrenheit. That eighty-eight degrees mark can easily be at or below the ambient temperature and when this occurs is when a transcritical system is required.cylinder pressure requirement of 400 psig rating (DOT 4B400 or DOT 4BW400) NOTE: Avoid storing R-410A where temperatures will exceed 120° F.
