Summary

Mini-channel heat exchangers (MCHE) are used in automobile applications due to their low weight and high compactness. Those MCHEs have just gained interest in stationary applications 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 the current new individual houses built in European countries. This paper compares performance and efficiency of a low-capacity heat pump (< 2 kW) with mini-channels as evaporator and condenser (mini-heat pump MHP) and an existing heat pump (EHP). This MHP is based on a third heat exchanger that will ensure an important part of a passive house heating demand. A numerical model of a heat pump is presented in order to achieve this comparison.
