摘要
A method and/or apparatus for at least one of: protecting the sub-surface metal refrigerant transport tubing of a DX heat pump system from corrosive sub-surface environments via a specially designed protective coating; efficiently insulating the sub-surface liquid refrigerant transport line in a DX heat pump system; and enhancing at least one of the convective heat transfer rate and the efficiency of at least a DX heat pump system; and where the outside diameter (OD) of a central containment core upon which to roll a spool of sub-surface refrigerant transport tubing is specially sized so as not to damage any tubing insulation and so as to avoid any S bends during ground loop installation.
