Appliance Performance Test Lab measuring Energy Efficiency for Electrical Water Storage Heaters
Standard:
IEC 60335-2-21 Safety of household and similar electrical appliances–Particular requirements for storage water heaters
GB 21516 Minimum allowable values of energy efficiency and energy efficiency grades for electrical storage water heaters
Application:
Performance Test Chamber for Electrical Water Storage Heaters. The equipment is mainly used for testing the heat storage type electric water heater. Appliance Performance Test Lab
Feature:
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.
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)
Main configuration:
| No. | Item | Description |
| 1 | Test chamber | Inner space size: L6000mmXW4000mmXH2600mm.( customizable) Temperature: 20 °C ± 2 °C. Humidity range: 60%. |
| 2 | Sample mounting bracket | Quantity: 2, installed in the test room, arranged on both sides, each test stand as a set of test devices, equipped with a water supply device. Each mounting station test station: 3, each test position is equipped with a test board. |
| 3 | Water supply room | Inner space size: L3000mmXW4000mmXH2600mm. Environmental control mode: convection and temperature control are carried out by using a ventilation window and an exhaust fan. |
| 4 | Storage tank | Quantity: Two, can set parameters independently, work independently, or work alternately. Inner space size: L1800mmX W800mmX H1750mm. |
| 5 | Refrigeration unit | Type: shell and tube type water-cooled chiller. Press brand: Copeland compressor. |
| 6 | Constant temperature and constant pressure water supply line pipe | Quantity: 2 channels, each corresponding to a test rack, with independent water supply, water pressure, flow, water temperature control and data acquisition system. |
| 7 | Pulse pressure test pipe | Quantity: 1 channel, located in the middle of the test room, with independent water supply, water pressure control and data acquisition system. Pulse frequency: 1-60Hz. |
| 8 | Control cabinet | Temperature control system: The water temperature control is realized by heating or cooling. The two storage tanks alternately control the temperature, and the water temperature is precisely controlled by PID control technology. |
