In the hot summer days, air conditioners and electric fans are essential household appliances for summer heat. What is the quality of this type of product? Recently, the Jiangsu Provincial Quality Supervision Bureau conducted a supervision and spot check on household air conditioners and electric fan products. The results of the spot checks showed that the air conditioner pass rate was close to 80%, and the electric fan pass rate was close to 95%.
The results of the spot check showed that 8 batches of the 35 batches of air conditioners were unqualified. The unqualified items involved cooling capacity, cooling power consumption, heat pump heat generation, heat pump heating power consumption, energy efficiency ratio, and protection against live parts. 6 indicators.
According to experts, the energy efficiency ratio refers to the ratio of cooling capacity to effective input power when the air conditioner is performing cooling operation under rated working conditions and specified conditions. This sampling found that the energy efficiency ratio of 8 batches of products was unqualified. In the spot check, it was also found that one batch of products failed to pass the protection items that touched the live parts, and there was a risk of leakage.
How to choose air conditioner? Expert suggestion: Generally calculate the cooling power of the air conditioner according to the cooling capacity of 200 watts per square meter of the housing area. For a room of about 10 square meters, a wall-mounted air conditioner with a cooling capacity of 2,500 watts can be used; for a living room or room of more than 30 square meters, a floor-standing air conditioner with a cooling capacity of more than 5,000 watts is required.
The supervision and spot check report of electric fan and air conditioner fan products showed that among the 34 batches of spot check products, 32 batches were qualified, and the pass rate was 94.1%. The unqualified items are four indicators of stability and mechanical hazard, mechanical strength, power connection and external cord, and air volume.
The spot check found that the two batches of product stability and mechanical hazard items were unqualified, and there was not enough protection for the fan blades. The floor fan base was not stable enough and was prone to dumping. In addition, there are 1 batch of products with unsatisfactory mechanical strength items, and the fan net cover is not strong enough to easily touch the fan blades during use, posing a hazard.
Expert suggestion: consumers should check the appearance of the electric fan when purchasing the fan, there should be no burrs or sharp edges; press the knob switch, it should be fixed firmly, flexible operation, clear pronunciation; check various screws, should No looseness. If you have the conditions, you can try it out. Listen to whether the motor is noisy during operation, see if the motor is shaking, and smell if the motor has a pungent smell after running for a while. After the electric fan has been running for half an hour, touch the motor casing with your hand to see if the temperature is too high. If it is hot, the motor is too hot and should be carefully purchased.
Semiconductor Stud Devices are mainly used for rectifying and switching
By using the unidirectional conductivity of the diode, alternating direction alternating current can be transformed into pulse direct current in a single direction.
Applications for Medium power switching and DC power supplies.
