The system effectively reduces domestic energy consumption by harnessing and reusing waste heat from wastewater, providing a sustainable and efficient heating solution.
Abstract
Description
Title of the invention: Heat recovery system from wastewater for reducing domestic energy consumption
[0001] The present invention relates to an innovative system for recovering heat from wastewater from domestic sanitary installations. This system is specifically designed to capture and exploit the residual heat from the drainage of water from showers, sinks and washbasins, with the aim of reducing domestic energy consumption.
[0002] The heat recovery system comprises a plate heat exchanger specifically positioned in the wastewater discharge pipes. This plate is structured to optimize the contact surface with the circulating wastewater, consisting of a configuration of tubes or cloths organized to maximize heat exchange and recover the heat emitted by the wastewater.
[0003] In addition to the heat exchanger, the invention incorporates a heat accumulator. This accumulator is designed to store the recovered heat, thus allowing its prolonged conservation. It may be a thermal battery or a device
[0004] similar, ensuring heat retention for later use.
[0005] This device captures waste heat and transfers it to a distribution system to heat the interior of the house. A portion of the captured heat is also directed to a cold water preheater, thereby helping to reduce the amount of energy needed to heat domestic water.
Claims
Claims
1. A heat recovery system as described, comprising a plate heat exchanger installed in the wastewater drainage pipes and a heat accumulator, configured to recover heat from the wastewater, store it and transfer it to a distribution system to heat the interior of a house and preheat incoming cold water, thereby reducing household energy consumption.
2. A system according to claim 1, wherein said heat accumulator is a thermal battery or similar device for storing recovered heat for later use.
