In the sales process of refrigerated display freezers, we often meet some customers blindly pursue cheap prices, but ignore the truth that a point of price is a point of goods. Today, we will simply explain to you how to judge the merits of a refrigerator.
First, look at appearance. Ensure that the design of the refrigerator is reasonable, the color of the supermarket refrigerator is relatively satisfactory, the surface is smooth, flat, no scratches and shaking. The interior structure must be soft, free of cracks and small bubbles, balanced everywhere, and free of odor and timing. The round exterior of the refrigerated display cabinet door should be flat, the parts should be firm, the cabinet door should not tilt, and the gap between the rotating shaft and the pin should be thoroughly paired. The foam liquid will not leak in the contact part of the beverage cabinet door, refrigerated display cabinet and door barrier
Second, run checks. The main engine is powered on. The door near the edge of the door in the refrigerated display case will close on its own due to the magnetic adsorption when the door closes, so no gaps should be found. Then check the refrigeration compressor. After switching on the power supply, check the cooling effect and observe the cooling speed of the freezer under no-load condition.
Third, check the status of the refrigerated display cabinet. 5 minutes after starting, check whether the refrigerated display cabinet has reached the predetermined temperature, and check whether the refrigerator is shut down and touch the condenser of the supermarket refrigerator by hand. To feel hot, the sooner you develop a fever, the better. When opening the cabinet door, you need to feel cool as long as you touch the evaporator.Even if the refrigerated display cabinet door is closed for about 20 minutes or so, part of the condenser is already very hot, open the drink cabinet door and look at the evaporator. The evaporator must have thin frost. If the frost is uneven, or if it is not found in some parts, the refrigerator in the refrigerated display case does not behave well.
Fourth, temperature controller. When the thermostat is adjusted to the shutdown part, the cold compressor must be shut down immediately. To strong cooling component adjustment, refrigeration compressor should continue to run; Run immediately for a while, and then turn itself on and off during that interval. The ambient temperature in the freezer should not exceed 5°c. This place is mainly to check whether the temperature control is accurate control compressor shutdown power saving.
The fifth listen to sound. As soon as the refrigeration compressor starts to start, the refrigerated display cabinet will shake slightly and produce working noise, but it cannot produce more than 45dB noise. This is equivalent to hearing only a slight clicking sound at a distance of about 1 meter in a quiet indoor environment. There can be no sound in the distance.Touching the freezer by hand does not require a very noticeable vibration.
Sixth, the speed of after-sales response is also a factor that affects its cost. With the business expansion of the manufacturer, sales freezers are all over the country, and after-sales teachers are all over the country. Whether the coordination response is timely or not, the maintenance price is getting higher and higher with the rise of labor costs.
Finally, to sum up with you, the expensive refrigerated display cabinet is not necessarily the most profitable, and the price is proportional to the quality.
