Bingham, G A

This patent describes a heat pump heating and/or cooling system containing freon-type fluid. The system includes above-ground components and an earth-type heat exchanger unit disposed during use of the system entirely below ground level. The improvement described includes a cylindrical coil assembly having cylindrical fluid-conducting coils extending in substantially concentric relationship to each other about the central axis of the assembly. Each of the coils is formed of heat conductive and corrosion resistant tubing. The tubing of each coil is of different diameter than the tubing of each other coil; a conduit interconnects the coil assembly and the above-ground system components, during operation of the system, conducting the fluid to and from fluid-conducting coils of the assembly.
