Résumé

This paper presents results from the integration of a microchannel heat exchanger (MCHEX) into a conventional R410A reversible air-to-water heat pump system. The overall goal of the investigation is to achieve an easy integration of the MCHEX into the baseline unit and an efficiency increase in both heating and cooling modes. The baseline unit was tested to establish operating conditions for properly designing the MCHEX into the heat pump system. The new system, equipped with the MCHEX, shows very encouraging results in terms of refrigerant charge reduction (nearly 50% versus baseline unit) and efficiency gain (about 15%) for cooling mode. Tests performed in heating mode demonstrate similar frosting characteristics to the baseline unit and successful draining of the condensed humidity.
