US Patent:

6904967, Jun 14, 2005

Filed:

Jul 2, 2002

Appl. No.:

10/186754

Inventors:

Melvin D. McLaughlin - Baltimore MD, US

International Classification:

F25B029/00

US Classification:

165201, 165 481, 165 45, 165 47, 165254, 165257, 622387

Abstract:

A system and method for structure heating, ventilation, and air conditioning (HVAC) that uses a heat exchanger to transfer heat between the structure and a subsurface storm water discharge chamber system is disclosed. Coils for heat management exchange are located in permanently collected runoff within a storm water management system beneath the frost line; the use of coils located within the retained runoff allows for improved heat exchange over coils placed within soil. Also described are a sensing device and feedback loop for HVAC control, to improve efficiency at ambient temperatures near the subsurface temperature.

Appl. No.:

09/352761

Inventors:

Melvin D. McLaughlin - Baltimore MD 21207

International Classification:

F24D 1100

US Classification:

165236, 165 45, 165 481, 62260

Abstract:

A system for providing heat conduction for a structure, comprising: a storm water management system located below a frost line and located near the structure, wherein a predetermined level of liquid is maintained within the storm water management system; a first heat exchanger located within the storm water management system, the first heat exchanger located such that the first heat exchanger is continuously immersed within the liquid maintained within the storm water management system; a connecting line connected to the first heat exchanger; and a second heat exchanger connected to the connecting line, wherein the second heat exchanger is associated with the structure and directly transfers heat with the structure; wherein the second heat exchanger transfers heat with the first heat exchanger via the connecting line.
