Electric Water Heater Appliance Performance Test Lab IEC 60379

Energy Efficiency Test System Electric Water Heater Appliance Performance Test Lab IEC 60379

 
Product information:
The equipment is mainly used for testing the heat storage type electric water heater. The equipment not only provides test water with constant water temperature and constant pressure for testing, but also timely data recording of the test process, and can select and calculate relevant numbers and generate test reports; The equipment has two water tanks. The two water tanks have the same function. They can alternately supply water for normal temperature test. Both have 25%, 50%, 75%, and 100% tank water running functions. The water supply test is provided by normal temperature tap water heating and cooling; The water is pressed into the water supply pipe by the water pump, and then divided into two groups to supply two test stations in the test room to supply the sample test. The test water is not recycled; the whole system consists of three parts: the water supply room, the test room and the control cabinet. The test room is separated from the heat preservation library board, the ground is provided with a drainage ditch, and the control cabinet is located outdoors, and the indoor condition can be observed through the glass window.
The system requires two sets of control modes of PLC+ industrial computer. The PLC programmable controller is the lower computer, which is responsible for the execution of system control commands, computer data reading, test data acquisition and other functions. The computer is the host computer data setting and command transmission. Generate data curve, data collection, process preservation and test report generation; System should have compressor overheating, overcurrent, overpressure protection, adjustable over temperature alarm, fan motor overheat protection, anti-dry protection, water shortage protection, overflow Safety protection measures such as flow protection, power phase sequence and phase loss protection, leakage protection, overload and short circuit protection. Both the water tank and the pipeline need to adopt perfect insulation measures, and the water flow is continuously circulated to ensure that the water temperature fluctuation at the inlet of the laboratory test bench is not more than 0.5 °C/min during the work.

Standard:
IEC 60379 Methods for measuring the performance of electric storage water-heaters for household purposes.  Appliance Performance Test Lab

Test items:
1) Heating efficiency (power meter)
2) 24h inherent energy consumption (power meter, data acquisition card)
3) Hot water output rate (thermocouple, flow meter, data acquisition card)
4) Temperature hysteresis , Temperature difference (thermocouple, data acquisition card)

Features:
1) The mode of alternate operation of two water tanks may avoid excessive power of the chiller and increase the continuous water supply capacity of the normal temperature water.
2) At the same time, there are two water supply pipes with the same function, which can test the two stations at the same time.
3) The test room adopts computer room air conditioner, which can control temperature and humidity at the same time, and the data precision is high.
