AI Technical Summary

Technical Problem

There is a need for alternative heat sources to replace gas combination boilers in small-scale residential and commercial facilities, as heat pumps are large, expensive, and require significant space and time to generate hot water, while existing systems waste energy and water due to inefficiencies in flow rates and temperatures.

Method used

A centralized water supply system with a control module using machine learning algorithms to manage flow rates and temperatures, incorporating heat pumps and electric heating elements, and thermal energy storage to optimize hot water delivery to multiple outlets, with sensors and processors for real-time adjustments.

Benefits of technology

Reduces energy and water consumption by optimizing hot water supply through precise temperature and flow rate control, eliminating the need for large storage tanks and reducing installation complexity and cost, while ensuring immediate hot water availability.

Abstract

The household hot water supply system includes a cold water inlet (302) for receiving cold water from a water supply source, a hot water outlet (304) connected to supply hot water on demand to a household hot water outlet operated by the user, a heat exchanger (308) for heating water using a high-temperature fluid received from a high-temperature fluid source (306), an electric heater (326), a heat storage device (342) for storing heat, a circulation pump (320) for sending water from the heat storage device (342) to the heat exchanger (308), and the heat exchanger (308) if sufficient high-temperature fluid is received from the high-temperature fluid source (306) to enable heating of water in the heat exchanger (308) using thermal energy from the high-temperature fluid. The system includes a controller (340) for controlling the operation of the system to provide hot water to the hot water outlet (304) by using heated water, or using water from a heat storage device (342) if the heat storage device (342) has enough heat stored in it to supply hot water, or by passing water from a heat exchanger (308) to the hot water outlet (304) via an electric heater (326) controlled to heat the water passing through it, and if it is determined that the hot water at the hot water outlet (304) is at a higher temperature than desired, to pass cold water from a cold water inlet (302) through to mix with the hot water and lower the temperature of the mixed water passed to the hot water outlet (304).
