Performance du transfert de chaleur d'un évaporateur à microcanaux pour une application avec pompe à chaleur.

Heat transfer performance of a minichannel evaporator for a heat pump application.

Résumé

Minichannel heat exchangers (MCHE) are used in automobile applications due to their low weight and high compactness. Those MCHE are just gaining interest in stationary application and they have a great potential for low heating capacity heat pumps to be installed in "passive houses" where the heating demand is 3 to 5 times lower than in the current new individual houses built in European countries. This paper compares the existing correlations developed for mini and macrochannel evaporators. A comparison is performed between rectangular minichannels whose hydraulic diameter varies between 0.6 and 1.2 mm, and a conventional round tube heat exchanger. The comparison also includes two refrigerants: R1234yf and R134a.
