| 摘要 |
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 exchange are located in permanently collected runoff within a storm water chamber 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.
