Definition and related terms of compressor wine cabinet

1) direct cooling: the direct cooling compressor wine cabinet is a natural heat conduction refrigeration mode, which reduces the temperature inside the cabinet through the natural convection of low temperature on the evaporator surface, so that the temperature difference inside the cabinet tends to be consistent, but it cannot be completely uniform. The temperature near the cold source point is low, and the temperature far from the cold source point is high. Compared with air-cooled compressor wine cabinet, direct-cooled compressor wine cabinet will be quieter because of less fan stirring. 2) Air cooling: the air-cooled compressor wine cabinet separates the cold source from the air in the cabinet, and the cold air in the cold source is pumped out by a fan and blown into the cabinet for stirring. The built-in fan promotes air flow and benign circulation, ensuring the uniform and stable temperature in different spaces in the wine cabinet.

3) Single temperature: Single temperature means that there is only one temperature zone in the wine cabinet, and the internal temperature is consistent.

4) Double temperature: Double temperature means that the wine cabinet is divided into two temperature zones and two parts: the upper part is the low temperature zone, and the temperature control range of the low temperature zone is generally 5 ~12℃; The lower part is a high temperature zone, and the temperature control range of the high temperature zone is 12~22℃.

5) Frequency conversion: the frequency conversion compressor can be divided into two parts, one is the frequency conversion controller, which is what we often call the frequency converter; The other part is the compressor. The principle of frequency conversion controller is to convert alternating current in power grid into square wave pulse output. By adjusting the German frequency of the square wave pulse (that is, adjusting the duty ratio), the speed of the motor-driven compressor can be controlled. Because frequency conversion can adjust the refrigeration capacity, the refrigeration capacity of the wine cabinet can be well matched with the load of the wine cabinet to avoid unnecessary energy consumption; When the refrigeration required by the wine cabinet is small, the compressor can run at a low speed, which reduces the number of times the wine cabinet is started.

6) Temperature zone: The temperature zone is an area with relatively consistent temperature. Wine cabinets can be divided into single-temperature wine cabinets, double-temperature wine cabinets and multi-temperature wine cabinets, of which the first two are more common.

7) Temperature control range: The temperature control range is the range of the lowest temperature and the highest temperature that the refrigeration system can control constantly.
