[0047] Instructions for use of the device: This device can realize energy efficiency testing of general commercial gas appliances, including but not limited to gas stoves, gas water heaters, ovens, etc. It is mainly used for energy efficiency testing of general commercial gas appliances.
[0048] The basic testing process for a commercial gas appliance is as follows:
[0049] S1. Turn on the control device 5 and preheat the gas appliance 2 to be tested. The first temperature acquisition device collects the ambient temperature of the test space of the gas appliance 2 in real time. When the test environment reaches a preset temperature range and maintains that temperature stable, the energy efficiency test begins.
[0050] S2. Accurately weigh the test medium using a high-precision weighing device, record its initial mass, and place the weighed test medium into a preheated commercial gas appliance;
[0051] S3. The gas consumption data collection device collects and records the gas flow data in real time; the collected gas flow data is fed back to the control device 5 in real time, and the control device 5 records the gas consumption and test time;
[0052] S4. The first temperature acquisition device and the second temperature acquisition device respectively acquire the test environment temperature and the target position temperature of the gas appliance to be tested in real time. The control device 5 records the test space environment temperature and the target position temperature of the gas appliance to be tested in real time per unit time, and forms a temperature rise curve.
[0053] S5. When the second temperature acquisition device detects that the temperature at the target position of the gas appliance to be tested has reached a preset temperature, the test medium is immediately removed, the removed test medium is weighed, and the remaining mass is recorded; the control device 5 stops timing after the test medium is removed and records the cumulative gas consumption and the test time;
[0054] S6. After the first temperature acquisition device detects that the test environment temperature has returned to the specified temperature, repeat steps S2 to S5 and perform at least 6 cycle tests. In each cycle test, the control device 5 records in real time the gas consumption, gas pressure, temperature change, mass change and other data parameters of the test medium during the test period; based on the recorded data, the actual energy efficiency of the product is calculated using a formula, and the test ends.
