The purpose of this paper is to report calculations of the vapor pressure and heat of vaporization (sublimation) for propane and propene for the temperature interval from 50 K to the respective normal boiling points. The calculation represents a numerical integration of the Clapeyron equation. Physic...
structure of a compressor of an air conditioner is provided to hold the pressure of refrigerant discharged from a compressor in a normal level by supplying and compressing some or whole of the refrigerant to the compressor again if the pressure of the refrigerant is lower than a normal value. ...
