Zusammenfassung: | The present invention relates to an energy performance test device for a water heater, capable of accurately obtaining target calories and a provided water discharge rate for a predetermined usage period by applying a real usage pattern. The energy performance test device for a water heater includes: a pipe forming unit controlling and supplying the calories and the flow rate of water inducted into and discharged to a water heater specimen in accordance with a test order and a usage pattern recorded in a database to perform the real usage pattern; a calorie flow rate sensing unit observing and controlling the flow rate bypassed and the difference of the flow rate inducted into and discharged from the water heater specimen, wherein the calorie flow rate sensing unit includes a discharged water flowmeter, an injected water flowmeter, and a temperature sensor installed in an inducting and discharging unit of the water heater specimen to control the calories and the flow rate; and a control unit storing, importing, or editing the real usage pattern by designating the real usage pattern and linked to a final real usage pattern. The control unit also can control the supply of an energy source supplied to the water heater specimen and a control valve of the pipe forming unit and can control the water supply pressure and the temperature of a constant-temperature water bath in accordance with a water induction setting condition. The control unit also comprises a control calculation unit and a database calculating calories of the discharged water of the water heater specimen and controlling the obtained data and operating a temperature and humidity sensor in an air conditioning room and temperature and pressure sensors of the constant-temperature water bath and the pipe forming unit. The control unit controls a power supply to the water heater specimen and controls the flow of the pipe forming unit using the control valve to follow the real usage pattern provided from the database based on calorie flow rate information transmitted from the calorie flow rate sensing unit.
