Description

Performance evaluation method of vehicle water heater The present invention relates to a method for evaluating the performance of a water heater for a vehicle, and more specifically, to a method for evaluating the performance of a water heater for a vehicle in which a performance test device is connected to the water heater to evaluate the performance of the water heater, and the test results obtained from the performance test device are transmitted to a program so that an operator can verify them. A vehicle water heater is a device that improves engine efficiency by maintaining the interior temperature even in cold weather or extreme climates, and helps improve fuel economy by enabling faster engine startup and minimizing fuel consumption. It also warms the air inside the vehicle and prevents condensation from forming on the windshield due to the temperature difference between the inside and outside, thereby preventing the driver's visibility from becoming obscured while driving. These types of vehicle water heaters include coolant heaters that utilize coolant heated by the engine, and systems using a heat source other than the engine, such as fuel combustion heaters, electric water heaters, and electric air heaters; these are applicable not only to general passenger cars but also to military vehicles and campervans. Such vehicle water heaters may fail to maintain optimal performance due to issues such as aging from prolonged use, necessitating periodic inspections. However, currently, there is no systematic method in place to evaluate the performance of vehicle water heaters. FIG. 1 is a flowchart of a method for evaluating the performance of a hot water heater for a vehicle according to an embodiment of the present invention, and FIGS. 2 to 10 are detailed explanatory diagrams illustrating in detail a method for evaluating the performance of a water heater for a vehicle. Hereinafter, the technical concept of the present invention will be explained in more detail using the attached drawings. The attached drawings are merely examples illustrated to explain the technical concept of the present invention in more detail, and therefore the technical concept of the present invention is not limited to the form of the attached drawings. FIG. 1 is a flowchart of a method for evaluating the performance of a hot water heater for a vehicle according to an embodiment of the present invention, and FIGS. 2 to 10 are detailed diagrams explaining in detail the method for evaluating the performance of a hot water heater for a vehicle. A method for evaluating the performance of a vehicle water heater according to an embodiment of the present invention includes, as illustrated in FIG. 1, an equipment connection step (S100), a circulation pump operation step (S200), an information input step (S300), a water heater inspection step (S400), and an inspection result verification step (S500). The equipment connection step (S100) means the step of connecting the hot water heater to the performance test equipment. Hot water heaters are heat exchangers widely used in electric vehicles, industrial heat exchangers, instantaneous water heaters, and water purifiers; they are also essential components of electric vehicles for battery temperature control, vehicle heating, and thermal management. The most important aspects in the design of such hot water heaters are cost-effectiveness and control performance; from a thermal perspective, control performance refers to the heater's short operating time, while cost-effectiveness refers to lightweight design. To evaluate the performance of such a hot water heater, the hot water heater is placed around the performance test equipment, and then the hose of the hot water heater is connected to the piping of the performance test equipment as shown in Fig. 2, and then the power line of the hot water heater is connected to the wire of the performance test equipment as shown in Fig. 3. The circulation pump operation step (S200) means the step of operating the circulation pump included in the hot water heater while the hot water heater is connected to the performance test equipment. A circulation pump is operated to preheat the hot water heater while the hot water heater subject to performance evaluation is connected to the performance test equipment. Specifically, as shown in FIG. 4, the valve of the hot water heater located between the hose of the hot water heater and the piping of the performance test equipment is opened, and then, as shown in FIG. 5, the circulation pump of the hot water heater is driven so that the hot water heater operates to heat the hot water. The information input step (S300) refers to the step of inputting information and inspection time of the hot water heater into a program stored on a server using a terminal. A performance test program stored on a server is executed using a terminal such as a mobile phone, smartphone, PC, or tablet PC, and as shown in FIG. 6, a hot water hea
