Energy Efficiency Testing Laboratory for Electric Water Storage Heaters 4 / 8/ 10 Stations
The equipment is mainly used for testing the electrical storage water heaters. 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.
Can be designed according to the following standards:
► IEC 60379
► IEC 60335-2-21
► Other standards
Types of UUT :
Electric Water Storage Heaters
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)
(Test software for reference, final language will be in English)
The constant water supply tanks are alternately supplied with water, and the two water supply tanks share a set of refrigeration equipment. When the water temperature of one water tank reaches a set value, the water tank performs water supply test, and the other water tank performs water storage and water temperature control; Test equipment, each set of three test stations, each set of a separate set of water supply systems, with independent pressure, flow, temperature data acquisition system; in the middle of the test room is dedicated to the pulsating pressure test station, all There is a return water branch at the test station. The purpose of the branch is to ensure that the water temperature in the test pipeline is consistent with the water temperature in the tank to reduce the impact of water temperature fluctuations on the test results.
The system is divided into three parts: test room, water supply room and console. The test room has strict temperature and humidity requirements and is realized by computer room air conditioner. The water supply room is mainly equipped with large equipment such as water supply system, water storage tank, water supply pump and cold water. The water tower of the refrigeration system is installed outside the test chamber; the above chambers are all separated by insulation storage panels, two doors are opened, doors and sides are opened with glass windows, drainage grooves are provided under the indoor floor, and drainage is passed through the building drainage ditches; It is installed on the outer side of the chamber, including the control cabinet and control computer. It is the data collection, data processing and control center of the system.
