How to judge the quality of the freezer?

There are many kinds of freezers on the market, good or bad. The quality of the refrigerator should be considered from the following aspects:
1: Look at the appearance, model, capacity and external label of the freezer. The appearance of spraying depends on whether there are obvious scratches, scratches, paint peeling and uneven color phenomena, whether the surface is obviously uneven, and whether the door is installed.
2: it is to inquire about publicity materials and brand features. The publicity materials are superficial, the content is simple, and the validity period is short. The news released by the official website is generally the latest and updated. You can check some official news online or call for advice. Three: Ask about the brand and origin of the compressor. Compressor is the heart of the commercial freezer, which directly affects the refrigeration performance, noise, service life and energy consumption of the freezer.
Four: experience the feeling of using goods, as well as the feeling of after-sales service and market reputation. Pinch the door evenly; Open the door seal to see if there are screws, because the screws will rust; Then compare the width and thickness of the door seal to see if there is an air bag, because this will affect the sealing performance of the commercial freezer.
Five: close the freezer door hard, high-quality freezer, the sound of closing the door is generally thicker.
