RECYCLED MATERIAL FOR EXISTING PIPE CONDUIT, METHOD FOR LAYING HEAT EXCHANGER USING THE SAME, AND SEWER PIPE EXHAUST HEAT UTILIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a recycled material for an existing pipe conduit that can efficiently lay a heat exchanger simultaneously with the repair of the existing pipe conduit.SOLUTION: A sewer pipe exhaust heat utilization system 1 includes a recycled material 3 for an existing pipe conduit; a heat pump 4 connected to heat exchanging passages 11 of the recycled material 3 for the existing pipe conduit; a heat storage device 5 storing thermal energy taken out by the heat pump 4; and an air conditioner 7 for heating and air-conditioning in a house 6. The recycled material 3 for the existing pipe conduit is provided on the inner wall surface 2a of a sewer pipe 2 to repair a damaged part. The recycled material 3 for the existing pipe conduit is integrally provided with the heat exchanging passages 11 allowing the flow of a heat transfer medium. The heat exchanging passages 11 of the recycled material 3 are connected to the heat pump 4 and the air conditioner 7 through exclusive piping 12, 13.
