Description

Technical Field

[0001] This utility model relates to the field of water heaters, and in particular to a space-energy water heater with intelligent temperature control. Background Technology

[0002] A solar water heater is a device that collects solar radiation and converts it into heat energy through a solar collector. It is widely used in homes, businesses, and industries to provide hot water. The main advantage of solar water heaters is that they utilize renewable solar energy, effectively reducing dependence on traditional energy sources and providing energy-saving and environmental benefits. Traditional solar water heaters typically include a collector, a storage tank, and a piping system to convert solar energy into hot water through heat exchange.

[0003] In existing technologies, the working efficiency of solar water heaters is affected by climate conditions. When there is insufficient solar radiation on cloudy, rainy, or winter days, their hot water supply capacity decreases and they cannot stably meet the hot water supply demand around the clock. In addition, traditional solar water heaters cannot perform temperature control regulation, making it difficult to meet users' requirements for a constant water temperature.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a space energy water heater that can provide hot water around the clock, is energy-saving and environmentally friendly, and has intelligent temperature control.

[0006] To achieve this objective, the present invention adopts the following technical solution: a space energy water heater with intelligent temperature control, comprising a solar collector, heat exchange pipeline, insulated water tank, frame, condenser coil, evaporator, compressor, liquid storage tank and expansion valve;

[0007] The heat exchange pipeline is located inside the solar collector and connected to the insulated water tank. The solar collector is used to heat the water flow in the heat exchange pipeline, and the heat exchange pipeline is used to transport the heated water flow to the insulated water tank.

[0008] The top of the frame is provided with an exhaust chamber, the top of the exhaust chamber is provided with an exhaust fan, the evaporator is located on both sides of the exhaust chamber, the evaporator is provided with refrigerant pipes, and the exhaust fan is used to draw external airflow into the refrigerant pipes for heat exchange.

[0009] The outlet end of the refrigerant pipeline is connected to the compressor through a first pipeline. The refrigerant pipeline is used to transport the low-pressure gas in the evaporator to the compressor for compression to form high-pressure, high-temperature gas. The outlet end of the compressor is connected to the condenser coil through a second pipeline.

[0010] The condenser coil is located inside the insulated water tank. The discharge end of the condenser coil is connected to the liquid storage tank through a third pipe. The condenser coil is used to exchange heat between the high-temperature and high-pressure refrigerant gas and the water in the insulated water tank, and to condense the refrigerant into a liquid state.

[0011] The top of the storage tank is connected to the expansion valve via a fourth pipe, and the outlet of the expansion valve is connected to the evaporator via a fifth pipe. The expansion valve is used to deliver low-temperature, low-pressure liquid refrigerant to the evaporator.

[0012] The insulated water tank is equipped with a temperature sensor, which is used to detect the temperature of the hot water in the insulated water tank.

[0013] Using the above technical solution, in the intelligent temperature-controlled space energy water heater, the solar collector includes a heat collection frame, a heat absorption plate, and a transparent cover.

[0014] The heat exchange pipeline is located inside the heat collection frame, and the heat absorption plate is placed on the heat collection frame. The heat absorption plate is used to absorb solar energy and transfer it to the heat exchange pipeline. The transparent cover plate is placed on the surface of the heat absorption plate to seal the heat collection frame.

[0015] Using the above technical solution, in the intelligent temperature-controlled space energy water heater, the heat exchange pipeline is arranged in a serpentine bend within the heat collection frame.

[0018] Using the above technical solution, in the intelligent temperature-controlled space energy water heater, the tilt angle between the solar collector and the horizontal plane is 40-60°.

[0019] The above-mentioned intelligent temperature-controlled space energy water heater also includes a controller, and the temperature sensor is electrically connected to the controller.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This utility model's solar collector heats flowing water using sunlight and then transports the heated water to an insulated water tank for storage, reducing heat loss. The exhaust fan and evaporator absorb heat from the outside air, converting low-pressure gas into high-pressure, high-temperature gas. This gas then exchanges heat with the water in the insulated water tank via the condenser coil, heating the water and causing the refrigerant to condense into a liquid state. The expansion valve reduces the pressure and temperature of the refrigerant, transporting the liquid refrigerant to the evaporator to prepare for the next heating cycle. A temperature sensor electrically connected to the controller monitors the water temperature in real time, activating the heat pump system to heat the water when the temperature is too low, thus avoiding energy waste and improving the water heater's energy efficiency.

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 6 As shown in the figure, this utility model embodiment provides a space-energy water heater with intelligent temperature control, including a solar collector 1, a heat exchange pipeline 2, an insulated water tank 3, a frame 41, a condenser coil 42, an evaporator 43, a compressor 44, a storage tank 45, and an expansion valve 46; the heat exchange pipeline 2 is located inside the solar collector 1 and connected to the insulated water tank 3, the solar collector 1 is used to heat the water flow in the heat exchange pipeline 2, and the heat exchange pipeline 2 is used to transport the heated water flow to the insulated water tank 3; the solar collector 1 can absorb sunlight and convert it into heat energy to heat the water flow in the heat exchange pipeline 2, and the heated water flow is transported through pipelines to the insulated water tank 3 for storage to reduce heat loss and make it available when needed.

[0034] The top of the frame 41 is provided with an exhaust chamber 410, and the top of the exhaust chamber 410 is provided with an exhaust fan 411. The evaporator 43 is located on both sides of the exhaust chamber 410. The evaporator 43 is provided with a refrigerant pipe 431. The exhaust fan 411 is used to draw external airflow into the refrigerant pipe 431 for heat exchange. The exhaust fan 411 can draw in external air and send it into the exhaust chamber 410, so that the low-pressure liquid refrigerant in the evaporator 43 can exchange heat with the external air. The refrigerant absorbs heat from the external air in the evaporator 43 and turns into a gaseous state, thereby realizing the conversion of heat energy.

[0035] The outlet end of the refrigerant pipe 431 is connected to the compressor 44 via a first pipe 51. The refrigerant pipe 431 is used to transport the low-pressure gas in the evaporator 43 to the compressor 44 for compression into high-pressure, high-temperature gas. The outlet end of the compressor 44 is connected to the condenser coil 42 via a second pipe 52. The condenser coil 42 is located inside the insulated water tank 3. The outlet end of the condenser coil 42 is connected to the liquid storage tank 45 via a third pipe 53. The condenser coil 42 is used to exchange heat between the high-temperature, high-pressure refrigerant gas and the water in the insulated water tank 3, and to cool the water. The refrigerant condenses into a liquid state; in the evaporator 43, the refrigerant absorbs heat from the outside air and is converted into low-pressure gas. This low-pressure gas is transported to the compressor 44 through the first pipe 51. The compressor 44 can compress the low-pressure gas into high-pressure and high-temperature gas, which greatly increases the temperature and pressure of the gas, thereby allowing the refrigerant to carry a large amount of heat energy. Then, the high-temperature and high-pressure gas from the compressor 44 is transported to the condenser coil 42 through the second pipe 52. After the refrigerant gas enters the condenser coil 42, the heat will be transferred to the water in the insulated water tank 3, heating the water through the heat exchange process. The refrigerant condenses into liquid refrigerant during the heat release process.

[0036] The top of the liquid storage tank 45 is connected to the expansion valve 46 via the fourth pipe 54, and the discharge end of the expansion valve 46 is connected to the evaporator 43 via the fifth pipe 55. The expansion valve 46 is used to transport low-temperature and low-pressure liquid refrigerant into the evaporator 43. The expansion valve 46 can reduce the pressure and temperature of the liquid refrigerant, making it a low-temperature and low-pressure liquid refrigerant, and then transport it to the evaporator 43 via the fifth pipe 55, thereby realizing the heat exchange cycle of the refrigerant and preparing it for the next heating cycle.

[0037] The insulated water tank 3 is equipped with a temperature sensor (not shown), which is used to detect the temperature of the hot water in the insulated water tank 3. The temperature sensor is electrically connected to the controller 47. The temperature sensor transmits the data to the controller 47 by measuring the water temperature in the insulated water tank 3. The controller 47 automatically adjusts the operating status of the heat pump system according to the temperature information provided by the temperature sensor. For example, when the water temperature is low, the controller 47 will activate the heat pump system or the solar collector 1 to heat the water to ensure that the water temperature reaches the preset value; when the water temperature is too high, the heat pump system will stop working to avoid overheating. This setting can optimize the energy-saving effect of the water heater and avoid energy waste.

[0038] like Figure 3As shown, the solar collector 1 further includes a heat collection frame 11, a heat absorption plate 12, and a transparent cover plate 13. The heat exchange pipe 2 is disposed within the heat collection frame 11, and the heat absorption plate 12 covers the heat collection frame 11. The heat absorption plate 12 is used to absorb solar energy and transfer it to the heat exchange pipe 2. The transparent cover plate 13 covers the surface of the heat absorption plate 12 to seal the heat collection frame 11. The heat absorption plate 12 is made of a material with good heat absorption performance, such as a black aluminum plate, and its surface is coated with a specific heat-absorbing coating, which can improve the absorption rate of solar energy. The heat absorption plate 12 can absorb solar radiation and convert it into heat energy, and then transfer the heat to the heat exchange pipe 2 through the heat absorption plate 12. The transparent cover plate 13 is located on the surface of the heat absorption plate 12, which can protect the heat absorption plate 12 from the influence of external environmental factors, such as rainwater and dust, while ensuring that sunlight can efficiently pass through the cover plate to irradiate the surface of the heat absorption plate 12.

[0039] like Figure 3 As shown, the heat exchange pipe 2 is arranged in a serpentine bend within the heat collection frame 11. The serpentine bend of the heat exchange pipe 2 can increase the path length of the water flow, thereby increasing its contact time with the heat absorption plate 12 and the surface area for heat exchange, thus improving the heat exchange efficiency of the solar collector 1.

[0040] Furthermore, the surface of the heat exchange pipe 2 is coated with a black chrome coating, which has good light absorption properties and can absorb sunlight to the maximum extent and convert it into heat energy.

[0041] like Figure 5 As shown, it further includes a gas-liquid separator 48, which is located between the compressor 44 and the condenser coil 42. The gas-liquid separator 48 is used to separate the gaseous refrigerant and liquid refrigerant mixed in the evaporator 43.

[0042] like Figure 2 As shown, the tilt angle between the solar collector 1 and the horizontal plane is 40-60°. In this embodiment, the tilt angle between the solar collector 1 and the horizontal plane is 50°. This setting can optimize the light receiving angle of the solar collector 1 to improve its heat collection efficiency.

[0043] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
