Specific embodiments
[0018] The utility model will be further described below in conjunction with specific embodiments, and the illustrative embodiments of the utility model and the description are used to explain the utility model, but not as the limitation of the utility model.
[0019] Embodiment 1
[0020] It includes installation platform 1, water supply pipe 2, equipment room 21, heat pump 3, circulation pipe 31, water tank 4, hot water outlet pipe 41, meter 411, return pipe 42 and temperature detector 43, installation platform 1 is connected with water supply pipe 2, and water supply pipe 2 is responsible for introducing external water source into the system.The liquid in water supply pipe 2 can be shunted to multiple heat pumps 3 through pipeline for warming, and the water purification mechanism is arranged on the pipeline of water supply pipe 2, so that the water quality before entering heat pump 3 is ensured to be clean, the influence of impurities on heat pump and subsequent pipeline is avoided, thereby prolonging the service life of the system and improving the working efficiency.
[0021] The front side of installation platform 1 is equipped with equipment room 21, and an intelligent control console is arranged in the inside, the intelligent control console is regarded as the "brain" of the whole system, the running state of each component is monitored and managed in real time, the heating power and circulation mode are dynamically adjusted according to the actual water demand, the energy utilization efficiency is further improved, and unnecessary energy consumption is reduced.The intelligent control system can also record and analyze historical data to provide optimization suggestions for users.
[0022] A plurality of energy-saving air heat pumps 3 are installed on installation platform 1, and each heat pump 3 is connected with a water tank 4 through two circulation pipes 31, the liquid in water supply pipe 2 is first shunted into each heat pump 3, and the heat pump 3 utilizes the heat in the air to warm the liquid, and the energy-saving air heat pump 3 design significantly reduces the high energy consumption problem caused by traditional electric heating or gas heating, and improves the energy efficiency ratio of the system, and each heat pump 3 corresponds to a water tank 4, so that the hot water supply of each region is independent and accurately controllable.
[0023] Each water tank 4 is connected to the corresponding heat pump 3 through two circulating pipes 31, forming a closed hot water circulation loop. The liquid in the water tank 4 is transmitted to the water use area through the hot water outlet pipe 41, and the hot water transmitted to the water use area is returned through the return pipe 42, realizing hot water circulation. The hot water outlet pipe 41 and the return pipe 42 are both wrapped with thermal insulation material, effectively reducing heat loss and maintaining the stability of hot water temperature. When the hot water use in the water use area stops for a period of time, the flow meter 411 will monitor the stop of water flow and automatically shut down the circulating pump to reduce the energy consumption of idling and further save energy.
[0024] The water tank 4 is provided with a plurality of temperature detectors 43, the detection probes of which are all inserted into the water tank 4 and in contact with the liquid therein, monitoring the water temperature change in real time. These temperature data are fed back to the intelligent control console, ensuring that the water temperature is always maintained within the set range, both ensuring the quality of hot water supply and avoiding energy waste caused by excessive heating. The pipe of the hot water outlet pipe 41 on the water tank 4 is provided with a flow meter 411 for monitoring the water flow. When the water flow is detected to stop for a period of time, the circulating pump is automatically shut down to prevent additional energy consumption caused by idling.
[0025] Among them, as shown in Figures 1-3 The installation base 1 is provided with a mounting seat 5 on one side of the rear part, and the mounting seat 5 is fixed with a filter tank 53 for purifying water quality. The filter tank 53 is provided with a plurality of filtering components, which can effectively remove impurities, suspended solids and harmful substances in water. The water flow in the water supply pipe 2 first flows through the filter tank 53, and in this process, impurities are intercepted by the filter material, ensuring that the water entering the subsequent system is pure. This not only protects the heat pump 3 and other pipeline equipment from corrosion and blockage, but also prolongs the service life of the system and improves the overall working efficiency.
[0026] The mounting seat 5 is provided with a constant pressure tank 54 on one side close to the filter tank 53, which mainly adjusts the water inlet pressure to ensure the stability of the water pressure in the system. The filter tank 53 and the constant pressure tank 54 are connected through a connecting pipe 55, and the filtered water flow flows into the constant pressure tank 54 through the connecting pipe 55. The constant pressure tank 54 is provided with a pressure regulating device inside, which can automatically adjust the water pressure according to the actual demand, so that it is maintained within a stable and suitable range. This stable water pressure avoids system failure or efficiency decline caused by water pressure fluctuation, ensures smooth and continuous water supply to the heat pump 3, and further improves the running stability of the system.
[0027] The connecting pipe 55 is not only a bridge between the filter tank 53 and the constant pressure tank 54, but also a key channel from the constant pressure tank 54 to the heat pump 3. The water flow adjusted by the constant pressure tank 54 directly flows into the heat pump 3 through the connecting pipe 55. Since the constant pressure tank 54 has ensured the stability of water pressure, the heat pump 3 can more efficiently perform heating operation when receiving water source, reducing energy waste and equipment loss caused by unstable water pressure. In addition, stable water pressure also helps to improve the working efficiency of the heat pump 3, reduce the heating time, and thus realize faster hot water supply.
[0028] Embodiment 2
[0029] Based on embodiment 1, as shown in Figures 1-3 The front part of the mounting seat 5 is provided with a dosing tank 51 for storing and providing necessary water treatment agents (such as disinfectants, scale inhibitors, etc.). The dosing tank 51 is provided with a connecting pipe 55 connecting the dosing tank 51 with the subsequent pipeline system. The agents in the dosing tank 51 can be accurately injected into the water flow through the connecting pipe 55, ensuring uniform distribution of the agents and improving the effect of water quality treatment.
[0030] One end of the dosing pipe 52 is connected with the constant pressure tank 54, and the other end is connected with the dosing tank 51 through the connecting pipe 55. The dosing pipe 52 is provided with a metering pump 521. The metering pump 521 can accurately control the injection amount of the agents according to the data feedback by the monitor 541. When the water flow passes through the constant pressure tank 54, the monitor 541 will detect the water quality parameters (such as pH value, residual chlorine concentration, etc.) in real time and transmit the data to the metering pump 521. Based on these data, the metering pump 521 can automatically adjust the injection amount of the agents to ensure that the water quality always meets the standard and avoid the problem of excessive or insufficient use of agents. This intelligent control mechanism not only improves the precision of water quality treatment, but also reduces the waste of agents and reduces the operating cost.
[0031] The monitor 541 is installed on the constant pressure tank 54 and is signal connected with the metering pump 521. The monitor 541 monitors the water quality parameters of the water flow in the constant pressure tank 54 in real time and feeds back the data to the metering pump 521. This closed-loop control system makes the agent injection process more accurate and can adjust the agent dose in time according to the actual water quality change to ensure that the water quality is stable and meets the requirements. In addition, the monitor 541 can also record the historical data of water quality change and provide detailed water quality report.
[0032] In addition, as shown in Figure 1 and Figure 4As shown, the heating element 6 is arranged on the pipeline of the return water pipe 42, which ensures that the hot water flowing back to the water tank 4 always maintains a proper temperature, and the return water in the return water pipe 42 will flow through the heating element 6 to be heated before returning to the water tank 4. The heating element 6 can heat the return water to a set temperature, which not only ensures the temperature consistency of the return water, but also avoids the problems of energy waste and heating efficiency reduction caused by the too low temperature of the return water.
[0033] Specifically, the heating element 6 works in linkage with the whole hot water circulation system through an intelligent control system, and when the return water temperature is lower than the set value, the heating element 6 will automatically start the heating function to ensure that the return water reaches the ideal temperature before entering the water tank 4. This design effectively prevents the temperature fluctuation caused by the mixing of cold and hot water, and at the same time, reduces the working load of the water tank 4 and the heating element, reduces the situation of frequent start and high load operation, and the heating system in the water tank 4 does not need to start heating from a lower temperature, thereby reducing the energy consumption, and the high-efficiency heating capacity of the heating element 6 also shortens the heating time required by the subsequent heat pump 3.
[0034] The above is only an embodiment of the present application and is not used to limit the present application. Any equivalent replacement within the principle of the present application shall be included in the protection scope of the present application. The contents not described in detail in the present application belong to the prior art known to the person skilled in the art.
