Title:
SYSTEM FOR PRODUCING HEAT FOR DOMESTIC HOT WATER OR CENTRAL HEATING
Document Type and Number:
WIPO Patent Application WO/2022/172867
Kind Code:
A1
Abstract:
The present application relates to a system (100) for producing domestic hot water and heat for central heating comprising a heat generator (1) for obtaining heat from a heat source, the heat generator having a generator outlet port (1.1) and a generator return port (1.2); a central heating circuit (3) having a heating feed port (3.1) and a heating return port (3.2); and a tank (16) having an inlet port (7), an upper port (8) and a lower port (9), the tank (16) containing a fluid which is a heat storing fluid, and the inlet port (7) being configured to feed the heat storing fluid (15) into the tank (16). The heat generator (1), the central heating circuit (3), and the tank (16) are fluidly connected in series so as to allow the fluid (15) to flow from the heat generator (1) via at least one of the central heating circuit (3) and the tank (16) back to the heat generator (1), and the system (100) further comprises a first three-way valve (4) fluidly connected to the heating feed port (3.1) and the heating return port (3.2) and configured to selectively let the fluid bypass, or flow through, the central heating circuit (3); a second three-way valve (6) fluidly connected to the first three-way valve (4), the generator return port (1.2), and the inlet port (7), and configured to selectively let the fluid bypass, or flow through, the tank (16) via the inlet port (7); and a third three-way valve (10) fluidly connected to the upper port (8), the lower port (9), and the generator return port (1.2), and configured to set a relative proportion by which the fluid flows through the upper port (8) and the lower port (9), respectively, to the generator return port (1.2).
