What is a freezer, what’s a display cabinet? Cold cabinet as the name implies is a cabinet with refrigeration, freezing, preservation of freshness, and display cabinets are display cabinets with display function. Of course, does not have the refrigeration function of the counter is also called display cabinets, this article says the display cabinets are with refrigeration function, please do not get confused.
First of all, we understand the principle of refrigeration: compressor compression of high-temperature and high-pressure gases generated by the external fan will be discharged through the heat, high-temperature and high-pressure gases through the cooling into a room temperature liquid (external heat dissipation is not good, the cooling is still high-temperature gases), the liquid through the expansion valve expansion and decompression into the inner machine evaporator heat absorption (which then produces a cold gas), the inner machine circulating fan will be cooled and transported to the specified Position, after evaporation of low-pressure low-temperature gas and back to the compressor compression, so the cycle.
In addition to the refrigeration system, the cold cabinet also has a heat preservation system, electronic control system, mechanical structure system. Thermal insulation system is to isolate the cabinet and cabinet air circulation, to prevent leakage of cold air; electronic control system is based on the required cabinet temperature to control the operation of the compressor or liquid solenoid valve, the temperature does not reach the set temperature, the compressor works to output the cold source, the temperature reaches the work will stop. That is, energy saving and to achieve the required temperature of the goods (too high or too low temperature is not good for the storage of goods); mechanical structure is the rationality of the manufacturer’s product design, aesthetics, humanization, applicability of the sum.
How to categorize the display cabinets, refrigerated cabinets and how to distinguish between them? (Refrigeration) display cabinets can be roughly categorized as follows: vertical cabinets, horizontal cabinets. Vertical cabinets can be divided into elevated cabinets, half-height cabinets, open and with glass forms of cabinets, such as refrigerators, fruit air curtain cabinets, vegetable cabinets, yogurt cabinets, beverage cabinets. Horizontal cabinets can be divided into island cabinets, counter cabinets, such as dumpling island cabinets, fresh cabinets, cake cabinets.
(Refrigeration) display cabinets can be roughly categorized by temperature as follows: single-temperature cabinets, such as refrigerated cabinets, freezers, such as 2-8 ℃ refrigerated fruits, vegetables, beverage cabinets, -18 ℃ frozen ice cream, dumplings, cabinets; dual-temperature refrigerated cabinets, such as mother and father cabinets, double-temperature refrigerators
(Refrigeration) display cabinets can be broadly categorized by product as follows: fruit cabinets, vegetable cabinets, cake cabinets, milk cabinets, cake cabinets, fresh cabinets, beverage cabinets, dumpling cabinets, deli cabinets, medicine cabinets.
Restaurant freezers have the following equipment: ice machines, refrigerators, workstations, wine coolers.
Convenience store coolers have the following equipment: ice cream machine, juice machine, hot chocolate machine, beverage cabinet.
