Can I read Thermostatic Expansion Valve Superheat Calculation on EtoBox?
Thermostatic Expansion Valve Superheat Calculation by Rajesh Shah is a document available to read on EtoBox.
What is Thermostatic Expansion Valve Superheat Calculation about?
The document discusses the degree of superheat in a refrigeration system using R12 as the refrigerant. Given an evaporator temperature of 4°C and a spring resistance of 60 kPa, the expected superheat is calculated to be 5°C. However, with a 22 kPa pressure drop in the evaporator, the actual superheat is calculated to be 7.1°C, indicating an externally equalized thermostatic expansion valve would be preferable to reduce superheat.
