Theoretical Analysis of a Passive Heat Pipe Heating and Cooling System.

摘要

A totally new concept which combines both a heat pipe and a flat plate solar collector for daytime solar water heating and nighttime water cooling has been studied theoretically. Since the heat pipe is a passive heat transfer device,the entire system requires no pumps or auxiliary power for its operation. This makes the system reliable and should require very little maintenance. This system with a collector area of 400sq ft can meet both winter space heating and summer space cooling requirements. For a typical winter day it can provide about 8000lbs/day of hot water at 140F or about 530,000Btu/day. For a summer day it can provide about 4000lbs/day of chilled water at 45F or about 100,000Btu/day for space cooling.
