OUTDOOR HEATING AND COOLING SYSTEM

摘要

A heat exchanging coil (21) is immersed in water (16) in a heating pod (20) heated over a fire (19) or other heat source. Flexible tubing (40) connected to the coil transmits heated water or other fluid under pressure from a water pump (35) in a reservoir (30) connected to the tubing. Loops of the tubing pass through various outdoor activity items including sleeping bags (50), tents (60), heaters (70), bowls (100), chairs (90), and a shower (122). The heated water is pumped intermittently in a continuously recirculating flow from the heating coil to the item(s) and back again through the heating coil. A timer (34) connected to the pump allows flow of the heated water bolus at any desired timed interval. Alternately, ice or snow or cold water may be used in the heating pod and the pump activate to circulate chilled water for cooling in conditions of extreme heat.
