Abstract

The bulb of a thermostatic expansion valve (TXV) is basically a temperature-pressure converter. It senses the temperature at the outlet of the evaporator, and the substance in the bulb (charge) generates the corresponding saturation pressure inside the bulb. The aim of the work presented in this paper is to develope a dynamic model that describes the system and thereby predicts the pressure in the system. The work will therby also question the rules of thumbs and instead use the model to predict the impact of changes.
