Description

Technical Field

[0001] This invention relates to the field of solar and air-source heating technology, specifically a combined solar-air-source coupled small-scale commercial pressurized hot water system. Background Technology

[0002] Currently, the mainstream heating equipment in the hot water sector mainly includes solar water heaters, electric water heaters, and gas water heaters. Electric water heaters, due to their ease of installation, lack of environmental influence, rapid heating, and good heat retention, occupy a major market share. However, they are also criticized for their small hot water volume and high operating costs. The emergence of air source heat pump water heating systems precisely addresses these shortcomings, better meeting people's needs for hot water systems. Traditional air source heat pump water heating systems suffer from problems such as inability to meet large water volume demands, inconsistent component quality and cumbersome connections, constantly exposed pumps and pipes, lack of warranty on accessories, inconvenient installation, scale and corrosion in pipes, and complex control switches. Summary of the Invention

[0003] The purpose of this invention is to provide a combined solar-air energy coupling small commercial pressurized hot water system to solve the problems mentioned in the background art. This invention systematically couples the functions of various components, which can not only meet the usage scenarios of all seasons and all weather, but also realize pipe-to-pipe connection through the integrated Water Easy Module, which facilitates maintenance and installation. The simple control logic makes the operation process simpler, more efficient and safer.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a combined solar-air-source coupled small commercial pressurized hot water system, comprising a series-connected all-glass heat pipe pressurized single unit system, an air-source water heater, and a water tank, wherein a water-effort module is coupled between the all-glass heat pipe pressurized single unit system, the air-source water heater, and the water tank, and the water-effort module comprises an integrated silicon phosphate crystal tank, a circulation pump, and a booster pump;

[0005] The air source water heater is connected to the water tank by an outlet pipe and a return pipe, and the circulation pump is installed on the return pipe.

[0006] The water tank is connected to the water terminal through the water supply pipeline. The water tank is equipped with an automatic sensing level gauge, and the booster pump is installed on the water supply pipeline. The all-glass heat pipe pressure single-unit series system is connected to the water supply pipeline, and the silicon phosphate crystal tank is installed on the water supply pipeline.

[0007] The automatic sensing level gauge senses the water level in the water tank. When water needs to be added, tap water enters the water replenishment pipeline, and calcium and magnesium ions in the water are removed by the silicon phosphate crystal tank. The water then enters the all-glass heat pipe pressure single-unit series system, where it is heated by solar energy. The hot water is then temporarily stored in the water tank and supplied to the water terminal.

[0008] If the circulating heating temperature is insufficient, start the circulating pump and air source water heater to circulate and heat the hot water in the tank until the water temperature in the tank reaches the usage temperature;

[0009] Start the booster pump, and the hot water in the tank will be supplied to the water terminals along the water supply pipeline.

[0010] Based on a large water tank, the system ensures a high-flow, long-term supply of hot water. It reduces operating costs, generates hot water quickly, is easy to connect and install, and saves space. The overall system has high compatibility and is easy to maintain, protecting pipes and valves while simplifying operation, allowing for flexible management in service, use, and after-sales support.

[0011] The all-glass heat pipe pressurized single-unit series system enables automatic water replenishment of the water tank, storing a certain amount of hot water and increasing the hot water storage capacity of the entire system.

[0012] In good weather, the all-glass heat pipe pressurized single-unit series system preheats tap water, increases the initial water temperature in the tank, reduces the time for circulating heating, and lowers the cost of using air source heat pumps.

[0013] The large-capacity water tank, paired with the air-source heat pump water heater, meets users' needs for large water volumes and flow rates. Furthermore, the use of the adaptable WaterEasy module makes the overall system more efficient and energy-saving.

[0014] As a further embodiment of the present invention, the WaterEasy Module includes an integrated housing, which further includes a water supply check valve, a water supply ball valve, and a water supply filter installed on the water supply pipeline. The water supply check valve is installed on the water supply pipeline between the silicon phosphate crystal tank and the all-glass heat pipe pressurized single-unit series system, and the water supply ball valve is installed on the water supply pipeline at the inlet end of the silicon phosphate crystal tank. The WaterEasy Module integrates a circulation pump, a booster pump, and a silicon phosphate crystal tank, facilitating rapid installation by technicians in various complex terrains without the need to consider complex pump and pipeline connections, significantly reducing installation time. It also greatly saves installation space and facilitates transportation and handling.

[0015] As a further embodiment of the invention, the integrated housing also includes a return water filter and a return water valve installed on the return water pipeline. The return water valve, return water filter, and circulation pump are arranged sequentially along the return water direction. A tee is provided at the outlet of the circulation pump, which is compatible with side-discharge or rear-discharge air source heat pump water heaters. The integrated installation of pipelines and valves allows for individual troubleshooting of the pump, valves, and pipelines, quickly identifying the root cause of problems. The rational layout of the circulation pump, booster pump, and silicon phosphate crystal tank saves space for pipeline connections, resulting in a larger hot water supply.

[0016] As a further embodiment 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 installed 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 outlet of the booster pump and the water supply valve is a universal ball valve.

[0017] As a further embodiment of the present invention, the integrated enclosure is made of sheet metal, with sound-absorbing cotton added to the inner wall of the enclosure. An electrical control box and control panel are located on one side wall of the integrated enclosure. The electrical control box contains a controller and a leakage current protector. A wiring hole is provided on the upper side wall of the integrated enclosure, through which external wires are electrically connected to the controller and leakage current protector. The controller is communicatively connected to the control panel. The addition of sound-absorbing cotton and vibration-damping pads reduces noise and resonance during operation, improves insulation, and reduces heat loss. The integrated electrical control box facilitates the connection of power and communication lines, and also makes it convenient for controlling switches and for technicians to perform maintenance.

[0018] The integrated housing has built-in handles on both sides and a mounting base inside. The mounting base is equipped with shock-absorbing pads, and the booster pump and circulation pump are mounted inside the integrated housing via the mounting base. This reduces resonance and ensures the booster pump and circulation pump are level.

[0019] As a further embodiment of the present invention, the water tank is an insulated water tank. The connection point between the water tank and the all-glass heat pipe pressurized single-unit series system is designated as a water inlet. An automatic sensing level gauge (float level gauge) is installed at the water inlet. A water temperature sensor is also installed at the water inlet. One side of the water tank, from top to bottom, has a circulation inlet, a water supply inlet, and a circulation outlet. The circulation inlet is connected to the outlet pipe. An electric heating rod is installed on the insulated water tank between the water supply inlet and the circulation outlet. An exhaust vent is located at the top of the water tank, and a drain outlet is located at the bottom. A drain pipe with a drain valve is installed on the drain pipe. The all-glass heat pipe pressurized single-unit series system can efficiently transfer energy from solar energy or other heat sources to the water. The heat pipe has high heat transfer efficiency, quickly transferring heat to the water in the tank and reducing heat loss. When solar energy or other heat sources are insufficient, the electric heating rod can automatically activate to provide auxiliary heating for the water in the tank, ensuring a continuous hot water supply and meeting the user's hot water needs under different weather conditions.

[0020] The float level gauge can monitor the water level in the tank in real time. When the water level is lower than the set value, it will automatically open the water inlet to replenish water, ensuring that there is always enough water in the tank and avoiding system malfunctions caused by insufficient water level.

[0021] The bottom of the water tank is equipped with a drain pipe and a drain valve to facilitate the control of the draining operation, regularly remove impurities and dirt from the water tank, prevent the water quality from deteriorating, and extend the service life of the water tank.

[0022] As a further embodiment of the present invention, the silicon phosphate crystal container is horizontally positioned, with a feeding port at the top and a threaded feeding cap at the feeding port. Feeding through the feeding port provides a convenient channel for adding silicon phosphate crystals, resulting in high feeding efficiency. The threaded feeding cap ensures the sealing of the feeding port, effectively preventing external impurities from entering the container and avoiding moisture or leakage of the silicon phosphate crystals, thus guaranteeing the quality and performance of the silicon phosphate crystals.

[0023] As a further embodiment of the present invention, the air source heat pump water heater and the WaterEasy module have a mounting frame at the bottom of their housing. The mounting frame includes a support frame, which comprises horizontal and vertical supports. Each horizontal and vertical support has an elliptical hole with a sliding nut inside. Six lifting legs are located at the bottom of the support frame, and diagonal braces are provided between the lifting legs and the vertical supports. This adapts to various uneven ground conditions. During installation, adjusting the height of the legs ensures the entire device is placed horizontally, preventing instability or damage due to ground tilt.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: The system includes a single-unit series system with pressure bearing of all glass heat pipes, an air source water heater and a water tank. A water-effort module is coupled between the single-unit series system with pressure bearing of all glass heat pipes, the air source water heater and the water tank. The water-effort module includes an integrated silicon phosphate crystal tank, a circulation pump and a booster pump.

[0025] The air source water heater is connected to the water tank by an outlet pipe and a return pipe, and the circulation pump is installed on the return pipe.

[0026] The water tank is connected to the water terminal through the water supply pipeline. The water tank is equipped with an automatic sensing level gauge, and the booster pump is installed on the water supply pipeline. The all-glass heat pipe pressure single-unit series system is connected to the water supply pipeline, and the silicon phosphate crystal tank is installed on the water supply pipeline.

[0027] Based on a large water tank, the system ensures a high-flow, long-term supply of hot water. It reduces operating costs, generates hot water quickly, is easy to connect and install, and saves space. The overall system has high compatibility and is easy to maintain, protecting pipes and valves while simplifying operation, allowing for flexible management in service, use, and after-sales support.

[0028] The all-glass heat pipe pressurized single-unit series system enables automatic water replenishment of the water tank, storing a certain amount of hot water and increasing the hot water storage capacity of the entire system.

[0029] In good weather, the all-glass heat pipe pressurized single-unit series system preheats tap water, increases the initial water temperature in the tank, reduces the time for circulating heating, and lowers the cost of using air source heat pumps.

[0030] The large-capacity water tank, paired with the air-source heat pump water heater, meets users' needs for large water volumes and flow rates. Furthermore, the use of the adaptable WaterEasy module makes the overall system more efficient and energy-saving.

[0031] The WaterEasy module integrates a circulating pump, a booster pump, and a silicon phosphate crystal tank, facilitating rapid installation by technicians in various complex terrains. It eliminates the need to consider intricate pump piping connections, significantly reducing installation time.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0043] Please see the appendix Figure 1 -Appendix Figure 9 A combined solar-air-source coupled small commercial pressurized hot water system includes a series-connected all-glass heat pipe pressurized single-unit system 3, an air-source heat pump water heater 2, and a water tank 4. A WaterEasy Module is coupled between the all-glass heat pipe pressurized single-unit system, the air-source heat pump water heater, and the water tank. The bottom of the air-source heat pump water heater 2 and the WaterEasy Module is provided with a mounting frame 9. The mounting frame includes a support frame, which includes a horizontal brace 902 and a vertical brace 901. Both the horizontal and vertical braces are provided with elliptical holes 903, and sliding nuts are provided in the elliptical holes. The bottom of the support frame is provided with six lifting legs 905, and diagonal braces 904 are provided between the lifting legs and the vertical braces.

[0044] The WaterEasy module includes an integrated silicon phosphate crystal tank 503, a circulation pump 801, and a booster pump 703.

[0045] The water tank is connected to the water terminal through the water supply pipeline. The water tank is equipped with an automatic sensing liquid level gauge 401 and a booster pump 703 is installed on the water supply pipeline. The all-glass heat pipe pressure single-unit series system is connected to the water supply pipeline 5, and the silicon phosphate crystal tank 503 is installed on the water supply pipeline 5.

[0046] The silicon phosphate crystal tank 503 is horizontally positioned, with a feeding port 402 at the top and a threaded feeding cap at the feeding port. The feeding cap is opened, and the remaining amount of silicon phosphate crystals is periodically observed. When the remaining amount of silicon phosphate crystals is insufficient, additional silicon phosphate crystals are added through the feeding port.

[0047] The water tank 4 is an insulated water tank. The connection between the water tank and the all-glass heat pipe pressure single-unit series system is set as a water inlet. An automatic sensing level gauge 401 is set at the water inlet. The automatic sensing level gauge senses the water level in the tank. The automatic sensing level gauge is a float level gauge.

[0048] When the water level is lower than the set water level, water tank 4 needs to be replenished. The integrated box is also equipped with a water replenishment check valve 504, a water replenishment ball valve 501 and a water replenishment filter 502 installed on the water replenishment pipeline. The water replenishment check valve is installed on the water replenishment pipeline 5 between the silicon phosphate crystal tank 503 and the all-glass heat pipe pressure single-unit series system, and the water replenishment ball valve is installed on the water replenishment pipeline at one end of the inlet of the silicon phosphate crystal tank.

[0049] Open the water supply check valve 504 and water supply ball valve 501, and tap water enters the water supply pipeline 5. The tap water passes through the silicon phosphate crystal tank to remove calcium and magnesium ions from the water, and then enters the all-glass heat pipe pressure single-unit series system to be heated by solar energy. The hot water is temporarily stored in the water tank 4 and supplied to the water terminal. Example

[0050] A water temperature sensor 403 is also installed at the water inlet to monitor the water temperature in the tank in real time.

[0051] The water tank has a circulating inlet, a water supply outlet, and a circulating outlet on one side, arranged from top to bottom. The circulating inlet is connected to the outlet pipe. An electric heating rod 405 is installed on the insulated water tank between the water supply outlet and the circulating outlet. When the water temperature sensor detects that the water temperature in the tank is not up to standard, the electric heating rod 405 is turned on to heat the water, causing the water temperature in the tank to rise. Once 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 user. Example

[0052] The top of the water tank 4 is equipped with a vent 402. During the use of the water tank, hot water generates steam. When the steam pressure is too high, the steam is released through the vent. Example

[0053] Water stored in a tank for extended periods is prone to bacterial and other microbial growth. The water also contains impurities such as sediment and rust, which gradually settle to the bottom of the tank. Over time, this sediment buildup not only affects water quality but also reduces the tank's effective volume, decreasing its actual water storage capacity.

[0054] The bottom of the water tank is equipped with a drain outlet, and a drain pipe 404 is installed at the drain outlet. A drain valve 441 is installed on the drain pipe.

[0055] The water in the tank is drained periodically by opening the drain valve 441, and the water in the tank is discharged along the drain pipe.

[0056] If the circulating heating temperature is insufficient, start the circulating pump and air source water heater to circulate and heat the hot water in the tank until the water temperature in the tank reaches the usage temperature;

[0057] When a water terminal needs hot water, the booster pump 703 is started, and the hot water in the water tank is supplied to the water terminal along the water supply pipeline. Example

[0058] The WaterEasy module includes an integrated housing 1, which is made of sheet metal. The inner wall of the housing is lined with sound-absorbing cotton, typically made of porous materials such as polyester fiber, glass wool, or rock wool. When sound waves enter the sound-absorbing cotton, they are reflected and refracted multiple times within its pores and rubbed against the fiber material, converting sound energy into heat energy, thereby reducing sound energy. This also reduces the noise generated by the pumps and valves operating within the integrated housing.

[0059] An electrical control box 102 and a control panel are located on one side wall of the integrated enclosure. The control box contains a controller and a residual current device (RCD). A wiring hole is located on the upper side wall of the integrated enclosure, through which external wires are electrically connected to the controller and RCD. The controller is communicatively connected to the control panel. The controller controls the opening and closing of various valves and pumps on the pipeline. During operation, the RCD determines whether there is a leakage by detecting the current difference between the live wire and the neutral wire. When the current difference reaches a set value (e.g., 30 mA), the RCD will cut off the circuit within a very short time (usually within 0.1 seconds), thus preventing electric shock.

[0060] The integrated box has built-in handles 101 on both sides for easy carrying and moving.

[0061] The integrated housing contains a mounting base 103, on which a shock-absorbing pad is installed. The booster pump and circulation pump are mounted inside the integrated housing via the mounting base. During operation, the vibrations generated by the booster pump and circulation pump are absorbed by the shock-absorbing pad, reducing vibration and noise. Example

[0062] The air source water heater is connected to the water tank by an outlet pipe 6 and a return pipe 8, and the circulation pump 801 is installed on the return pipe 8.

[0063] The integrated housing also includes a return water filter 802 and a return water valve 803 installed on the return water pipeline. The return water valve 803, return water filter 802, and circulation pump are arranged sequentially along the return water direction. A tee is provided at the outlet of the circulation pump, which is compatible with either a side-discharge or rear-discharge air source heat pump water heater. It connects to the side-discharge air source heat pump water heater through the tee, or to the rear outlet of the tee.

[0064] The air source water heater is connected to the water tank by an outlet pipe 6 and a return pipe 8. When the air source water heater is running, the hot water produced is transported to the water tank through the outlet pipe for temporary storage and supply to the water terminal.

[0065] The circulation pump 801 is installed on the return water pipe. When the water temperature sensor 403 detects that the water temperature in the water tank is not up to standard, the circulation pump 801 is started, so that the water in the water tank flows back to the air source water heater through the return water pipe for heating. The hot water is circulated into the water tank through the outlet water pipe until the water temperature in the water tank reaches the set water temperature. Then the circulation pump stops, and the hot water is temporarily stored in the water tank for use by the water terminal. Example

[0066] The water tank stores a large amount of hot water, and the water temperature has reached the usable temperature.

[0067] The integrated housing 1 is also equipped with a water supply valve 701, a water supply filter 702 and a water supply check valve 704 installed on the water supply pipeline 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 outlet of the booster pump 703 and the water supply valve 701 is a universal ball valve.

[0068] When hot water is needed at the water terminal, the water supply valve 701 is opened, and hot water flows to the water terminal along the water supply pipeline. The hot water first passes through the water supply filter 702, and then through the booster pump 703. The booster pump 703 automatically adjusts the output flow and pressure according to the water demand. When the water consumption increases, the booster pump 703 will automatically increase its speed and increase the output flow; when the water consumption decreases, the booster pump 703 will decrease its speed and decrease the output flow.

[0069] The 704 water supply check valve prevents hot water from flowing back into the water tank and provides one-way output for use by the end user.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
