Building in Climate Zone 6, where cold temperatures should be expected, Dana is weighing his options for aheating and cooling system, and it’s narrowed down to either an air-source or a ground-source heat pump.
Both systems have their advantages. Air-source devices are much less expensive to install. Ground-source heat pumps don’t lose as much efficiency in very low temperatures. And there’s a hybird option–ductless mini-splits, which are a type of air-source heat pump that use a central condensor to serve several fan-coil units.
Dana在GreenBuildingAdvisor问答论坛上的帖子提出了许多答复。有些人由于其较低的天气效率而偏爱地面源路线,并且因为它们可以更精确地控制条件空气。
Others like air-source devices, and particularly the ductless minisplits, because of their lower initial cost, and ease of repair and maintenance.
