Delphi announced the launching of Delphi MCHX Outdoor Heat Pump Coil. The coil operates outdoors in an air-sourced heat pump system, and functions as a traditional condenser in cooling mode and as an evaporator in heating mode. It is up to 50% lighter, 30% smaller in volume, 100% recyclable, provides up to 40% less refrigerant usage and uses a unique and efficient defrost process.

Additionally, in the past, using an indoor micro channel coil with an outdoor copper tube and fin coil caused a significant charge imbalance, which required more refrigerant usage and loss of efficiency. Now OEMs can end the compromise in performance by using Delphi's micro channel technology both inside and outside so the charge imbalance is eliminated and the system performs optimally with a lower refrigerant charge. Delphi's innovative approach virtually eliminates the traditional inefficiencies of the heat pump coil just by applying its micro channel technology and its 100-plus years of automotive cooling system engineering know-how.

The Delphi MCHX(R) family uses brazed aluminum construction and is based on the micro channel technology, which consists of three components: a flat micro channel tube, fins and two refrigerant manifolds joined together in a single coil. The 'channels' provide more fluidity, cohesion and efficiency than round tubes.
