鮮肉柜可以分為水冷卻式、風冷式、水和空氣聯合冷卻式三種類型，其實這三種類型是有很大的區別的，存儲的食物不同，溫度范圍不同、工作原理不同。

　　1.水冷卻式：是以冷藏柜中的冷藏器用水作為冷卻介質。超市鮮肉柜使 高溫高壓的氣態制冷劑冷凝的設備。

　　2.風冷式：利用空氣作為冷卻介質向發電機定子和轉子繞組以及定子鐵心進行冷卻的系統。該系統通常有開式通風和閉式循環兩種冷卻方式。

　　3.水和空氣聯合冷卻式：冷凝器采用水和空氣聯合冷卻方式的冷凝器包括淋水式冷凝器和蒸發式冷凝器兩大類。在這兩類冷凝器中，制冷劑在管內冷凝，冷卻水噴灑在傳熱管外。在淋水式中，制冷劑放出的熱量大部分依靠空氣自然對流帶走，少量的熱量是由水的汽化吸熱帶走。

　　如超市中的冷柜大多是風冷式的。風冷式冷柜都是微孔式送風設計，冷柜里面還有超大蒸發面積銅管，制冷速度快，不易風干能夠充分保證食物中的水分和營養物質，食物的保鮮展示效果好。這種鮮肉柜一般用來保存熟食或者新鮮的肉類。存儲飲料的鮮肉柜常用冷凝器是一個制冷劑向外放熱的熱交換器。自壓縮機經油分離器來的制冷劑蒸氣進入鮮肉柜冷凝器后，將熱量傳遞給周圍介質水或空氣，自身因受冷卻凝結為液體，從而使得鮮肉柜內部溫度降低，達到保存飲料的效果。
 

　　Fresh meat cabinet can be divided into three types of water cooling, air cooling, water and air combined cooling. In fact, the three types are very different. The stored food is different, the temperature range is different, and the working principle is different.

　　1. water cooling type: refrigerating water in refrigerated cabinet is used as cooling medium. Supermarket fresh meat cabinet to make high temperature and high pressure gas refrigerant condensing equipment.

　　2. air-cooled type: air cooling system is used to cool generator stator and rotor windings and stator core. The system usually has two ways of cooling: open ventilation and closed cycle.

　　3. water and air combined cooling type: condenser adopts water and air combined cooling mode condenser including two types of water condenser and evaporative condenser. In these two types of condensers, refrigerant condenses in the tube and the cooling water sprays outside the heat transfer tube. In sprinkling water, most of the heat released by refrigerant is carried away by natural convection, and a small amount of heat is taken away by vaporization of water.

　　For example, most of the refrigerators in the supermarket are air-cooled. The air-cooled refrigerator is the design of microporous air supply, and there is a large copper tube in the refrigerator, which is fast in cooling speed and not easy to dry. It can fully guarantee the moisture and nutrients in the food, and the preservation of the food is good. This kind of fresh meat cabinet is usually used to preserve cooked food or fresh meat. The fresh meat cabinet used for storing drinks is usually a condenser which is used to heat the refrigerant outwards. After the refrigerant steam from the compressor through the oil separator enters the condenser of the fresh meat cabinet, the heat is transferred to the surrounding medium water or air, and the temperature of the inside of the fresh meat cabinet is reduced because of the cooling condensation, thus the effect of the beverage is saved.
