Description

Technical Field

[0001] This utility model relates to the field of building hot water supply technology, specifically to a hot water control system for villas, which is particularly suitable for solving the problems of water temperature fluctuations, uneven water pressure, and energy waste in scenarios with multiple water usage points. Through the synergistic effect of a dynamic balancing distributor, a phase change thermal storage unit, and a mixing valve, this system has the advantages of energy efficiency, high efficiency, and rapid output of constant-temperature hot water, belonging to the field of hot water control technology for villas. Background Technology

[0002] Traditional villa hot water systems often use a central water heater with a circulating pump for water supply. However, this system has several problems. When multiple water outlets are turned on simultaneously, uneven water distribution causes sudden drops in water temperature in some areas, especially at distant outlets where it takes a long time to run cold water before hot water is available. Furthermore, conventional heat storage methods, such as electric water heaters, suffer from large storage tanks, significant heat loss, and high energy consumption, failing to meet users' needs for instant hot water. Therefore, there is an urgent need for a more efficient heat storage villa hot water system to improve water comfort and reduce overall energy consumption. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A hot water control system for villas includes a central water heater, a dynamic balancing manifold, a phase change thermal storage unit, a mixing valve, and the dynamic balancing manifold itself. The dynamic balancing manifold has an inlet and several outlet branches. The inlet of the dynamic balancing manifold is connected to the outlet of the central water heater. Each outlet branch of the dynamic balancing manifold is connected in series with the phase change thermal storage unit and the mixing valve. The mixing valve and the cold water inlet of the central water heater are both connected to the water supply pipe. The dynamic balancing manifold has a built-in flow sensor and an electric regulating valve, which automatically adjusts the valve opening based on real-time water pressure and flow feedback from each branch to ensure balanced water pressure at multiple water points. The mixing valve mixes hot and cold water and adjusts the outlet water temperature in real time to achieve rapid output of constant-temperature hot water.

[0005] Furthermore, the phase change thermal storage unit includes a shell, a heat exchanger, an electric heating rod, and phase change thermal storage material. The heat exchanger is located inside the shell, with its two ends connected to an inlet pipe and an outlet pipe, respectively. The electric heating rod is located inside the shell, which is filled with phase change thermal storage material. The electric heating rod is connected to mains power to heat the phase change thermal storage material. The phase change thermal storage unit completes thermal storage before the user uses hot water, ensuring that the user can use hot water immediately upon application.

[0006] Furthermore, the phase change thermal storage unit is also equipped with a temperature sensor to collect the temperature of the phase change thermal storage material in the phase change thermal storage unit. When the temperature of the temperature sensor is less than or equal to the set value, the electric heating rod is connected to the mains power to heat the phase change thermal storage material and complete the thermal storage, so that the user can use hot water immediately. When the temperature of the temperature sensor is greater than or equal to the set value, the electric heating rod is disconnected from the mains power.

[0007] Furthermore, the space between the phase change thermal storage unit shell and the phase change thermal storage material is filled with thermal insulation cotton to prevent the phase change thermal storage material from transferring heat to the shell.

[0008] The beneficial effects of this utility model are:

[0009] This invention utilizes a dynamic balancing manifold to adjust the flow rate of each branch in real time, and combines this with the constant-temperature heat release characteristics of a phase change thermal storage unit to achieve stable water temperature and balanced pressure at multiple water points. This invention solves the problem of large water temperature fluctuations in traditional villa hot water systems and meets the need for rapid output of constant-temperature hot water from remote water points.

[0013] The present invention will be further described below with reference to the accompanying drawings;

[0014] like Figures 1 to 2 This utility model discloses a hot water control system for villas, comprising a central water heater, a dynamic balancing distributor 1, a phase change thermal storage unit 2, a mixing valve 3, and the dynamic balancing distributor 1. The dynamic balancing distributor 1 has an inlet and several outlet branches. The inlet of the dynamic balancing distributor 1 is connected to the outlet of the central water heater. The phase change thermal storage unit 2 and the mixing valve 3 are connected in series on each outlet branch of the dynamic balancing distributor 1. The mixing valve 3 and the cold water inlet of the central water heater are both connected to the water supply pipe 9. Each water point (such as shower, washbasin, etc.) obtains hot water through the mixing outlet of the mixing valve 3.

[0015] The dynamic balancing manifold collects water pressure and flow data of each branch in real time. When multiple water points are turned on at the same time, the dynamic balancing manifold dynamically adjusts the opening of the electric regulating valve of each branch to ensure that the water pressure of each branch is balanced.

[0016] like Figure 2 As shown, the phase change thermal energy storage unit 2 includes a shell 4, a heat exchanger 5, an electric heating rod 6, a temperature sensor 8, and an insulation layer 7. The shell 4 is filled with phase change thermal energy storage material (such as paraffin or inorganic salts). The heat exchanger 5 is located inside the shell, with its two ends connected to an inlet pipe and an outlet pipe, respectively. The electric heating rod 6 is located inside the shell, which is filled with phase change thermal energy storage material. The electric heating rod is connected to mains power to heat the phase change thermal energy storage material. A 10-50mm thick layer of insulation cotton 7 is provided between the shell 4 and the phase change thermal energy storage material. The insulation cotton 7 is made of centrifugal glass wool with a density of 10kg / m³ and a thickness of 30mm to reduce heat loss to the outside and ensure thermal energy storage efficiency.

[0017] During the heat storage stage of the phase change thermal storage unit 2, when the temperature sensor 8 detects that the temperature of the phase change thermal storage material is lower than the set value, the electric heating rod 6 is turned on to heat the phase change thermal storage material to the set value using the mains power, thus completing the heat storage preparation.

[0018] During the heat release phase of the phase change thermal storage unit 2, when the user uses water, the dynamic balance water distributor 1 distributes the water flow to the corresponding branch. When the water flows through the heat exchanger 5, it absorbs the latent heat released by the phase change thermal storage material, quickly rises to the preset temperature, and outputs constant temperature hot water through the mixing valve 3.

[0019] The mixing valve has a temperature regulation function, allowing users to quickly obtain hot water at the desired temperature (e.g., 38℃) by adjusting the hot and cold water mixing ratio. Since the phase change thermal storage unit 2 continuously provides a stable supply of hot water, the mixing valve 3 does not require frequent adjustments to maintain a stable outlet water temperature.

[0020] The operating principle of this invention is as follows: When two shower rooms in the villa are opened simultaneously, the dynamic balancing water distributor 1 detects water pressure fluctuations at both locations and automatically adjusts the opening of the corresponding branch valves to ensure balanced water flow in both lines. The phase change heat storage unit 2 transfers the stored heat energy to the water flow through the heat exchanger 5, keeping the hot water temperature constant. The mixing valve 3 mixes the hot and cold water and outputs hot water at a suitable temperature, which users can use immediately without waiting for the water to heat up.

[0021] The above embodiments are merely illustrative of the technical solutions of this utility model, and not intended to limit it. Those skilled in the art can adjust the specific parameters or structures according to actual needs, and such adjustments should be covered within the scope of the claims of this utility model.
