Abstract

The paper aims to compare and choose the most suitable criteria equation for the computation of the convective heat transfer coefficient on the refrigerant side of the evaporator. The comparison is carried out by considering a given air handling unit equipped with a specific evaporator operating with refrigerant R134a. A mathematical model is given. The results obtained for criteria equations available in the work of Shah (1982), Gungor and Winterton (1987) and Kandlikar (1999) have been compared. The first criterion equation of Shah (1982) is selected because it leads to a value for the evaporator pipe length close to the one measured on the air handling unit and also it can be applied for a wider range of refrigerants used in the field of air conditioning.
