In-pipe installed wastewater heat recovery system "Heat Liner Method"
A method for utilizing unused clean energy "heat from sewage."
The "Heat Liner Method" is a technology that effectively utilizes the thermal energy of sewage, which has a stable temperature compared to outside air, for air conditioning, hot water supply, floor heating, and snow melting. Simultaneously with the rehabilitation of aging pipes, a heat exchange tube installed at the bottom of the pipe circulates antifreeze to transport heat to facilities for use as a heat source. In an era of aging infrastructure where sewer pipes constructed during the period of rapid economic growth are reaching their renewal phase, this technology realizes the effective utilization of untapped energy alongside the rehabilitation of sewer pipes. 【Features】 - Heat extraction is possible from small to medium diameter sewer pipes (less than Ø800mm). - The heat exchange mat is located at the bottom of the pipe, allowing for stable heat extraction. - Cost savings can be achieved by simultaneous construction with pipe rehabilitation. - There is no obstruction to flow, and perforation of the installation pipe is possible. - The heat extraction section is designed to not come into direct contact with sewage, eliminating any odors. - Once installed, thermal energy can be utilized permanently (with a lifespan similar to that of sewer pipes, approximately 50 years). - It can be applied not only for air conditioning and hot water supply but also for water heaters, baths, floor heating, and snow melting (road heating and roof snow melting). 【Applications】 - Utilization of sewage thermal energy for air conditioning, hot water supply, snow melting, etc.
