Embodiment 1

[0034] Example 1: No water flow regulator or pressure regulator

[0035] Under the condition that the pressure in the cold water chamber is 4.5 bar and the volume flow rate of cold water is 8.6 L / min, the output temperature is 36.8°C. When the pressure in the cold water chamber drops to 1.5 bar and the volume flow rate of the cold water drops to 0 L / min, the outlet water temperature rises to 44°C, a rise of 7.2°C.

Embodiment 2

[0036] Embodiment 2: Set the water flow regulating device and the pressure regulating device, the hot water remains unchanged, and the pressure of the cold water changes

[0037] Table 1: Example 2 Pressure settings:

Embodiment 3

[0043] Embodiment 3: Set the water flow regulating device and the pressure regulating device, the cold water remains unchanged, and the pressure of the hot water changes

[0047] Table 4: Example 3 test results:

[0048]

[0049] The above exemplified tests show that through this embodiment, when the water level of the water mixer is kept constant, the pressure of the cold and hot water is changed within the range of 2 to 5 bar, and the temperature of the cold and hot water is fixed at 30 degrees Celsius and 60 degrees Celsius respectively, the outlet water temperature is between In most cases, it is kept at about 39.2±1.5°C.

[0050] This embodiment provides a system for keeping the outlet water temperature of the cold and hot water mixing system substantially constant when the upstream inlet water changes unexpectedly. This system is especially beneficial in environments such as apartment complexes o...

Abstract

A system for the regulation of water supply temperature, particularly in a domestic setting where multiple users are connected to a common water supply is provided. The system comprises a water mixingchamber with separate inlets for hot water and cold water from a hot water chamber and a cold water chamber respectively, and an outlet for the mixed water. The system includes a pressure regulatingdevice comprising a pressure release valve connected to the water mixing chamber and the outlet. When the pressure at either the hot water inlet or the cold water inlet of the mixing chamber decreases, a portion of the mixed water about to exit the outlet is recirculated to the mixing chamber by the pressure release valve of the pressure regulating device; the temperature in the water mixing chamber is thus maintained within a desired temperature range.

Description

technical field [0001] The invention relates to a cold and hot water mixer system, especially the water temperature adjustment of a household cold and hot water mixer system. Its envisaged use is in particular for regulating the temperature of shower water in environments such as apartment complexes or hotels where several users are connected to the same water supply. Background technique [0002] Consistent water temperature is difficult to achieve when more than one user is connected to a single water source. This problem is often encountered where multiple showers are connected to a single water source. Typically, users set the water temperature of their showers to a desired level. When a subsequent user turns on a shower or other faucet connected to the same water source, the temperature of the water at the previous user's location suddenly increases or decreases. Also, this problem recurs every time a subsequent user turns on the shower. As a corollary, the closing ...
