Description

Technical Field

[0001] The present invention relates to the technical field of solar energy and air energy heating, and in particular to a combined solar energy and air energy coupled small commercial pressurized hot water system. Background Art

[0002] Currently, the mainstream heating equipment in the hot water sector is primarily solar water heaters, electric water heaters, and gas water heaters. Electric water heaters dominate the market due to their ease of installation, environmental resistance, rapid heating, and excellent insulation. However, they are also criticized for their low hot water output and high operating costs. The emergence of air-source water heating systems addresses these shortcomings, further satisfying consumers' expectations for hot water systems. Traditional air-source water heating systems cannot meet large water volume demands, suffer from inconsistent component quality and cumbersome connections, and have long-term exposure to water pumps and pipes, lack warranty on accessories, are difficult to install, suffer from scale corrosion within the pipes, and have complex control switches. Summary of the Invention

[0003] The purpose of the present invention is to provide a combined solar-air-energy coupled small commercial pressurized hot water system to solve the problems raised in the above-mentioned background technology. The present invention systematically couples the functions of various components, which can not only meet the use scenarios of all seasons and all weather, but also realizes pipe-to-pipe connection through the integrated Shuiyifang module, which is convenient for maintenance and installation, and uses simple control logic to make the operation process simpler, more efficient and safer.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: a combined solar-air coupled small commercial pressurized hot water system, comprising a full-glass heat pipe pressurized single-unit series system, an air-energy water heater, and a water tank; a Shui Yi Fang module is coupled between the full-glass heat pipe pressurized single-unit series system, the air-energy water heater, and the water tank; the Shui Yi Fang module includes an integrated silicon-phosphorus crystal tank, a circulation pump, and a booster pump; A water outlet pipe and a water return pipe are provided between the air energy water heater and the water tank, and a circulation pump is provided on the water return pipe; The water tank is connected to the water terminal through a water supply pipeline. An automatic induction liquid level gauge is installed in the water tank, and a booster pump is installed on the water supply pipeline. The all-glass heat pipe pressure-bearing single-unit series system is connected to a water supply pipeline, and a silicon phosphorus crystal tank is installed on the water supply pipeline. The automatic induction liquid level gauge senses the liquid level in the water tank. When water replenishment is needed, tap water is input into the water replenishment pipeline, and the calcium and magnesium ions in the water are removed by the silicon phosphorus crystal tank. The water then enters the all-glass heat pipe pressure-bearing single-unit series system and is heated by solar energy. The hot water is then temporarily stored in the water tank for use by the water terminal. When the circulating heating temperature is not enough, start the circulating pump and the air energy water heater to circulate and heat the hot water in the water tank so that the water temperature in the water tank reaches the use water temperature; Start the booster pump and the hot water in the water tank is supplied to the water terminal along the water supply pipeline.

[0005] Based on a large water tank, the system ensures high-flow, long-term hot water supply. This reduces operating costs, quickly generates hot water, and is easy to connect and install, saving space. The overall system is highly coordinated and adaptable, allowing for easy maintenance. This protects piping and valves while simplifying operation, allowing for flexible control throughout service, use, and after-sales service.

[0006] The all-glass heat pipe pressure-bearing single-unit series system realizes automatic water replenishment of the water tank, stores a certain amount of hot water, and increases the hot water storage capacity of the entire system; In good weather, the all-glass heat pipe pressurized single-unit series system preheats the tap water, increases the initial water temperature in the water tank, reduces the cycle heating time and reduces the cost of air energy use.

[0007] The large-capacity water tank and air-energy water heater meet the user's needs for large water volume and high flow rate. At the same time, the use of adaptive Shuiyifang modules makes the overall system more efficient and energy-saving.

[0008] As a further embodiment of the present invention, the Shui Yi Fang module includes an integrated housing, which is further equipped with a water supply check valve, a water supply ball valve, and a water supply filter, which are installed on the water supply pipeline. The water supply check valve is installed on the water supply pipeline between the silicon-phosphorus crystal tank and the all-glass heat pipe pressure-bearing single-unit series system, and the water supply ball valve is installed on the water supply pipeline at the inlet end of the silicon-phosphorus crystal tank. The Shui Yi Fang module integrates a circulation pump, a booster pump, and a silicon-phosphorus crystal tank, making it easy for installers to quickly install in various complex terrains without having to worry about how to connect the complex water pump pipeline, greatly reducing installation time. This can significantly save installation space and facilitate transportation and handling.

[0009] As a further solution of the present invention, the integrated housing also houses a return water filter and valve on the return water line. These valves, filter, and circulating pump are arranged sequentially along the return water line. A tee is located at the outlet of the circulating pump, which is compatible with either a side-discharge air-energy water heater or a rear-discharge air-energy water heater. The integrated installation of the piping and valves allows for independent troubleshooting of the pump, valves, and piping, quickly identifying the source of any problem. The rational layout of the circulating pump, booster pump, and silicon-phosphorus crystal tank saves space for piping connections and maximizes hot water supply.

[0010] As a further solution of the present invention, the integrated box is also provided with a water supply valve, a water supply filter and a water supply check valve arranged on the water supply pipeline. The water supply valve, water supply filter, booster pump and water supply check valve are arranged in sequence along the water supply direction. A water flow switch is provided at the water outlet of the booster pump, and the water supply valve is a universal ball valve.

[0011] As a further solution of the present invention, the integrated box is made of sheet metal, with silencer cotton installed on the inner wall of the integrated box. An electric control box and control panel are installed on one side wall of the integrated box. The electric control box contains a controller and leakage protector. Wire holes are provided on the upper side wall of the integrated box. External wires are electrically connected to the controller and leakage protector through the wire holes, and the controller is connected to the control panel for communication. The addition of silencer cotton and shock-absorbing pads reduces noise and resonance during operation, improves thermal insulation, and reduces heat loss. The integrated electric control box facilitates the connection of power and communication lines, and also facilitates control switches and maintenance by technicians.

[0012] The integrated box has built-in handles on both sides, and a mounting base is provided inside the integrated box. The mounting base is equipped with a shock-absorbing pad. The booster pump and circulating pump are installed inside the integrated box through the mounting base to reduce resonance and ensure the level of the booster pump and circulating pump.

[0013] As a further embodiment of the present invention, the water tank is an insulated water tank. The water tank is connected to the all-glass heat pipe pressure-bearing single-unit series system at a water inlet. An automatic sensing liquid level gauge is set at the water inlet. The automatic sensing liquid level gauge is a float level gauge. The water inlet is also provided with a water temperature sensor. A circulating water inlet, a water supply port, and a circulating water outlet are provided on one side of the water tank from top to bottom. The circulating water inlet is connected to the water outlet pipeline. An electric heating rod is provided on the insulated water tank between the water supply port and the circulating water outlet. An exhaust hole is provided at the top of the water tank. A sewage outlet is provided at the bottom of the water tank. A sewage outlet is provided at the sewage outlet. A sewage pipeline is provided on the sewage pipeline. A sewage valve is provided on the sewage pipeline. The all-glass heat pipe pressure-bearing single-unit series system can efficiently transfer energy from solar energy or other heat sources to water. The heat pipe has high heat transfer efficiency and can quickly transfer heat to the water in the water tank, reducing heat loss. When solar energy or other heat sources are insufficient, the electric heating rod can automatically start to provide auxiliary heating for the water in the water tank, ensuring the continuity of hot water supply and meeting the hot water needs of users in different weather conditions.

[0014] The float level gauge can monitor the water level in the water tank in real time. When the water level is lower than the set value, the water filling port will be automatically opened to replenish water, ensuring that there is always enough water in the water tank to avoid system operation failures caused by insufficient water level.

[0015] The bottom of the water tank is equipped with a sewage pipe and a sewage valve to conveniently control the sewage operation, regularly discharge impurities and dirt in the water tank, prevent the water quality in the water tank from deteriorating, and extend the service life of the tank water.

[0016] As a further embodiment of the present invention, the silicon-phosphorus crystal tank is horizontally arranged, with a feed port at the top of the tank, which is fitted with a threaded feed cap. This port provides a convenient channel for adding silicon-phosphorus crystals, increasing feeding efficiency. The threaded feed cap ensures a tight seal, effectively preventing foreign matter from entering the tank and preventing moisture or leakage of the silicon-phosphorus crystals, thereby ensuring their quality and effectiveness.

[0017] As a further embodiment of the present invention, a mounting bracket is provided at the bottom of the housing of the air-energy water heater and Shuiyifang module. The bracket comprises a support frame, which includes horizontal and vertical braces, each of which has an elliptical hole containing a sliding nut. Six lifting legs are provided at the bottom of the support frame, with diagonal braces located between the legs and the vertical braces. This allows for adaptability to various uneven floor conditions. During installation, the height of the legs can be adjusted to ensure the overall horizontal placement of the equipment, preventing unstable operation or damage due to tilted ground.

[0018] Compared with the existing technology, the beneficial effects of the present invention are as follows: the system includes a full-glass heat pipe pressure-bearing single-unit series system, an air-energy water heater and a water tank; a water-yifang module is coupled between the full-glass heat pipe pressure-bearing single-unit series system, the air-energy water heater and the water tank; the water-yifang module includes an integrated silicon phosphorus crystal tank, a circulation pump and a booster pump; A water outlet pipe and a water return pipe are provided between the air energy water heater and the water tank, and a circulation pump is provided on the water return pipe; The water tank is connected to the water terminal through a water supply pipeline.

The all-glass heat pipe pressure-bearing single-unit series system is connected to a water supply pipeline, and a silicon phosphorus crystal tank is installed on the water supply pipeline. Based on a large water tank, the system ensures high-flow, long-term hot water supply. This reduces operating costs, quickly generates hot water, and is easy to connect and install, saving space. The overall system is highly coordinated and adaptable, allowing for easy maintenance. This protects piping and valves while simplifying operation, allowing for flexible control throughout service, use, and after-sales service.

[0019] The all-glass heat pipe pressure-bearing single-unit series system realizes automatic water replenishment of the water tank, stores a certain amount of hot water, and increases the hot water storage capacity of the entire system; In good weather, the all-glass heat pipe pressurized single-unit series system preheats the tap water, increases the initial water temperature in the water tank, reduces the cycle heating time and reduces the cost of air energy use.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1 Please see the attached Figure 1 -Attached Figure 9 A combined solar-air-energy coupled small commercial pressurized hot water system includes a full-glass heat pipe pressure-bearing single-unit series system 3, an air-energy water heater 2 and a water tank 4. A Shui Yi Fang module is coupled between the full-glass heat pipe pressure-bearing single-unit series system, the air-energy water heater and the water tank. A mounting frame 9 is provided at the bottom of the box body of the air-energy water heater 2 and the Shui Yi Fang module. The mounting frame includes a support frame, which includes a horizontal support 902 and a vertical support 901. Both the horizontal support and the vertical support are provided with an elliptical hole 903, and a sliding nut is provided in the elliptical hole. Six lifting legs 905 are provided at the bottom of the support frame, and a diagonal support 904 is provided between the lifting legs and the vertical support.

[0026] The Shuiyifang module includes an integrated silicon phosphorus crystal tank 503, a circulation pump 801 and a booster pump 703; The water tank is connected to the water terminal 701 through a water supply pipeline. An automatic induction liquid level gauge 401 is installed in the water tank. A booster pump 703 is installed on the water supply pipeline. The all-glass heat pipe pressure-bearing single-unit series system is connected to a water supply pipeline 5. The silicon-phosphorus crystal tank 503 is installed on the water supply pipeline 5. The silicon-phosphorus crystal tank 503 is horizontally disposed, with a feed port 402 at the top. A threaded feed cap is provided at the feed port. The cap is opened to periodically check the remaining silicon-phosphorus crystals. When the remaining silicon-phosphorus crystals are insufficient, the silicon-phosphorus crystals are replenished from the feed port.

[0027] The water tank 4 is an insulated water tank. The place where the water tank is connected to the all-glass heat pipe pressure-bearing single-machine series system is set as a water supply port. The automatic sensing liquid level gauge 401 is set at the water supply port. The automatic sensing liquid level gauge senses the liquid level in the water tank. The automatic sensing liquid level gauge is a float level gauge, which senses the water level.

[0028] When the water level is lower than the set water level, the water tank 4 needs to be replenished with water. The integrated box is also provided with a water replenishment one-way valve 504, a water replenishment ball valve 501 and a water replenishment filter 502 arranged on the water replenishment pipeline. The water replenishment one-way valve is arranged on the water replenishment pipeline 5 between the silicon-phosphorus crystal tank 503 and the all-glass heat pipe pressure-bearing single-machine series system, and the water replenishment ball valve is arranged on the water replenishment pipeline at one end of the silicon-phosphorus crystal tank inlet.

[0029] Open the water supply check valve 504 and the water supply ball valve 501, and input tap water into the water supply pipe 5. The tap water passes through the silicon phosphorus crystal tank to remove calcium and magnesium ions in the water, and then enters the all-glass heat pipe pressurized single-unit series system to be heated by solar energy. The hot water is temporarily stored in the water tank 4 and used by the water supply terminal 701; Example 2 A water temperature sensor 403 is also provided at the water filling port, and the water temperature sensor detects the water temperature of the water tank in real time.

[0030] One side of the water tank is equipped with a circulating water inlet, a water supply inlet, and a circulating water outlet from top to bottom. The circulating water inlet is connected to the water outlet pipeline. An electric heater 405 is installed on the insulated water tank between the water supply inlet and the circulating water outlet. When the water temperature sensor detects that the water temperature in the water tank is not up to standard, the electric heater 405 turns on to heat the water, raising the water temperature in the water tank. When the water temperature reaches the set temperature, heating stops, and the hot water is temporarily stored in the water tank for use by the water terminal 701.

[0031] Example 3 An exhaust hole 402 is provided on the top of the water tank 4. When the water tank is in use, hot water generates steam. When the steam pressure is too high, the steam is exhausted through the exhaust hole.

[0032] Example 4 If water is stored in a water tank for a long time, it can easily breed bacteria and other microorganisms. Water contains impurities such as silt and rust, which gradually settle to the bottom of the tank. Over time, this sediment accumulates, affecting not only water quality but also taking up the tank's effective volume, reducing its actual storage capacity.

[0033] A sewage outlet is provided at the bottom of the water tank, a sewage outlet is provided with a sewage pipe 404, and a sewage valve 441 is provided on the sewage pipe.

[0034] The water in the water tank is discharged regularly. The drain valve 441 is opened and the water in the water tank is discharged along the drain pipe.

[0035] When the circulating heating temperature is not enough, start the circulating pump and the air energy water heater to circulate and heat the hot water in the water tank so that the water temperature in the water tank reaches the use water temperature; When the water user terminal needs to use hot water, the booster pump 703 is started, and the hot water in the water tank is supplied to the water user terminal along the water supply pipeline.

[0036] Example 5 The Shuiyifang module includes an integrated housing 1, constructed from sheet metal. The inner walls of the housing are fitted with sound-absorbing cotton, typically made from porous materials such as polyester, glass wool, and rock wool. When sound waves enter the cotton, they are reflected and refracted multiple times within its pores, rubbing against the fibers and converting the sound energy into heat, thereby reducing the sound's energy and minimizing noise generated by the operation of the pumps and valves within the housing.

[0037] An electrical control box 102 and a control panel are located on one side of the integrated cabinet. The control box houses a controller and a leakage protector (RCD). Wire holes are provided on the upper side of the integrated cabinet, through which external wires are electrically connected to the controller and RCD. The controller is also connected to the control panel for communication. The controller controls the opening and closing of valves and pumps in the pipelines. During operation, the RCD detects leakage by detecting the current difference between the live and neutral wires. When the current difference reaches a set value (e.g., 30 mA), the RCD disconnects the circuit in a very short time (typically within 0.1 seconds), preventing electric shock accidents.

[0038] Built-in handles 101 are provided on both sides of the integrated box to facilitate the transfer of the integrated box.

[0039] The integrated box is provided with a mounting base 103, on which a shock-absorbing pad is provided. The booster pump and the circulating pump are arranged in the integrated box through the mounting base. During the operation of the booster pump and the circulating pump, the vibration generated is absorbed by the shock-absorbing pad, thereby reducing vibration and noise.

[0040] Example 6 A water outlet pipe 6 and a water return pipe 8 are provided between the air energy water heater and the water tank, and a circulating pump 801 is provided on the water return pipe 8; The integrated box is also equipped with a return water filter 802 and a return water valve 803 on the return water pipeline. The return water valve 803, the return water filter 802, and the circulation pump are arranged in sequence along the return water direction. The outlet of the circulation pump is provided with a tee, which is adapted to a side-outlet air-energy water heater or a rear-outlet air-energy water heater. The tee is connected to the side-outlet air-energy water heater or to the outlet air-energy water heater through the rear port of the tee.

[0041] A water outlet pipe 6 and a water return pipe 8 are provided between the air energy water heater and the water tank. When the air energy water heater is running, the hot water generated is transported to the water tank through the water outlet pipe for temporary storage and use at the water supply terminal.

[0042] The circulation pump 801 is arranged on the return water pipe; when the water temperature sensor 403 detects that the water temperature in the water tank does not meet the standard, the circulation pump 801 is started, so that the water in the water tank flows back to the air-energy water heater through the return water pipe for heating and heating. The hot water is circulated into the water tank through the outlet pipe until the water temperature in the water tank reaches the set water temperature. The circulation pump is paused, and the hot water is temporarily stored in the water tank for use by the water user terminal.

[0043] Example 7 A large amount of hot water is stored in the water tank, and the temperature of the hot water reaches the usage temperature.

[0044] The integrated box 1 is also provided with a water supply valve 701, a water supply filter 702 and a water supply check valve 704 arranged on the water supply pipe 7. The water supply valve 701, the water supply filter 702, the booster pump 703 and the water supply check valve 704 are arranged in sequence along the water supply direction. A water flow switch is provided at the water outlet of the booster pump 703, and the water supply valve 701 is a universal ball valve.

[0045] When a user needs hot water, the water supply valve 701 is opened, and hot water flows along the water supply pipeline to the user. The hot water first passes through the water supply filter 702 and then passes through the booster pump 703. The booster pump 703 automatically adjusts the output flow rate and pressure according to water demand. When water consumption increases, the booster pump 703 automatically increases the speed, increasing the output flow rate; when water consumption decreases, the booster pump 703 decreases the speed, reducing the output flow rate.

[0046] The water supply one-way valve 704 prevents the hot water in the water tank from flowing back, and the one-way output is used by the user terminal.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all points of view, the embodiments should be regarded as illustrative and non-restrictive.
