Description

<p>This paper constitutes Part 1 in a series of studies on preheating hot water supply systems using a palisaded heat exchanger combined with plastic pipes and hot spring water. The palisaded heat exchanger was newly developed, and the initial plan was for it to utilize hot springs as a sustainable source of energy and solve the corrosion or clogging problem in metal plate heat exchangers. The exchanger consists of two units that sandwich each other alternately. The units consist of eight or nine panels connected by horizontal pipes. The panels are formed by thermal fusion bonding between 40 narrow longitudinal pipes and upper and lower horizontal header pipes with bored holes. Heat exchange is initiated by soaking the exchanger in a tank with hot spring water or waste hot water. The width, height, and depth of the prototype exchanger are 893, 1023, and 560 mm, respectively. The overall heat transmission coefficient of the exchanger is 65-73 W/(m2·K). Though this value is less than that of the metal plate or tube-type heat exchanger, the exchanger appears to work well when heat recovery from the following types of springs is carried out: springs that corrode metal because of the low pH value and springs with plenty of suspended solids, such as waste hot water from the spa facilities.</p>
