R-448A N40 Refrigerant PT Chart June 29, 2020 by Alec Johnson One of the very first steps when it comes to diagnosing your home air conditioner, refrigerator, or even your vehicle’s air conditioner is understanding the temperature and the current pressure that your system is operating at. ...
Use the following property data, flow chart and properties to help you understand the basics when working with refrigerants. Forane®PT chart Use this PDF for all your pressure/temperature needs. PT Chart (PDF) Forane®PT iPhone®App ...
The refrigerant must be a stable substance that will not decompose under the pressure and temperature of the refrigeration system. Less stable substances can swell, embrittle or dissolve plastics used in motor and system seals. Refrigerants should also not react chemically with lubricants and other ...
The temperature at which the vapor pressure of the liquid refrigerant equals the absolute external pressure of the liquid-vapor interface / The temperature at a specified pressure at which the first stable vapor forms above a liquid. From: Ludwig's Applied Process Design for Chemical and Petrochemi...
This app provides convenient access to refrigerant pressure/temperature (PT) charts as well as other physical properties for common refrigerants. Temperature can be displayed in degrees Celsius or Fahrenheit. Bubble and Dew Pressures are provided on the same line of the PT chart. User selectable set...
