【 Weak current College 】 refrigerator inspection points to note in the seven-Power By 【 China power house network 】
Check refrigerator to follow from the outside and inside. First appearance, in determining the refrigerator model is correct, you can observe the color is out of the fridge, smooth, flat surface, non-scratch touch and loose. Lumen requires smooth, no cracks and bubble, no uneven situation, no smell and severe acne, etc. Box and door around the Assembly should be straight, not skewed door firmly, and its axis of rotation and the gap between the shaft pin with good. Door, Cabinet and costume opening, contact Department, foaming liquid not leaking.
Power on after press experts suggest that can be used to test by seven survey of "internal" in the fridge.
First, check the door. Closed door close to the door frame is due to the magnetic strip of suction and closed automatically, should not have the slit.
Second, the compressor. When the power is switched on, the refrigerator will immediately start into the running state; cut off power supply when the refrigerator unplanned; again, in a second compressor should be able to start up and running.
Third, the "hybrid". Compressor starts after the refrigerator will vibrate and produce running noise, noise should not be higher than 45 DB, i.e., in a quiet environment, you can only hear the hum of the compressor minor, at about one metre from the fridge, the distance should be can't hear the sound. Touch the box, there should be clear of vibration.
Fourth, inspection lamps. Open the refrigerator door, box light, door close completely turned off, lamp off.
Fifth, refrigeration. Refrigerator running 5 minutes after startup, fingered fridge condenser (on both sides in the refrigerator or back), there should be a feeling of heat, and so hot that the sooner the better; open door of the refrigerator, fingered evaporator, due to the cold sensation; close the door for 20 minutes or so, condenser parts is very hot, open door closer evaporator, above should have a thin layer of uniform cream, ifevaporation of Frost is not uniform or a site not Frost, the refrigerator cooling performance is poor. Consumers can put in the fridge for a few cups of cold boiled water after the refrigerator to the "frozen" status, by freezing time, efficiency to test the ability of frozen refrigerator and compressor performance.
Sixth, the temperature control. When the thermostat adjustment in the stop position, the compressor should be immediately stopped; transferred to the strong cold location, the compressor should be running go; refrigerator running for some time, should be able to press a certain interval automatically open, stop, at this point, the cool temperature should not exceed 5 ° c, freezing room temperature should reach the stars; General compressor start times per hour must not be more than 6 ~ 9 times.
Seventh, the examination of whether the fridge starts after two hours whether automatic shutdown or no downtime, cold storage room temperature is not greater than 10 ° c, frozen indoor temperature from-5 ° c or below.
Preservation is also a large refrigerator performance critical indicators, you can put in the refrigerator a few apples, two days after the observation of fresh apples, although this can not be timely arrival of the goods, but at least you can prevent consumers from foresight.
