AN ENERGY PERFORMANCE TEST APPARATUS AND TEST METHOD WHICH CAN CONTROL ACCURATELY THE SCHEDULES OF VARIABLE FLOW RATE AND VARIABLE CALORIE FOLLOWING THE REAL USAGE PATTERN

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. 본 발명은, 실사용 패턴을 반영하여 일정 사용기간 동안의 주어진 출수량, 목표열량을 정밀하게 구현할 수 있는 온수기 에너지성능 시험장치에 있어서, 실사용 패턴을 구현하기 위하여 데이터베이스에 기록된 사용패턴 및 시험순서에 따라서 온수기 시료로 입출수 되는 유량과 열량을 제어 및 공급하는 배관구성부; 상기 유량과 열량을 제어하기 위하여 상기 온수기 시료의 입출수단에 설치되는 온도센서, 입수유량계, 출수유량계를 포함하고, 상기 온수기 시료로 입출수 되는 유량의 차이 및 바이패스되는 유량을 관측 및 제어할 수 있는 열량 유량 감지부; 및 상기 실사용 패턴을 지정하여 저장하거나 불러오기 또는 편집할 수 있고, 최종 실사용 패턴에 연동되고, 상기 배관구성부의 제어밸브 및 상기 온수기 시료로 공급되는 에너지원 공급을 조절
