1、空氣預冷：空氣預冷方法具有空氣溫濕度易調節、可用于各種食品冷卻冷藏運輸、設備造價低等優點。

1. Air precooling: air pre cooling method has the advantages of easy adjustment of air temperature and humidity, and can be used for various kinds of food cooling, refrigeration, transportation and low equipment cost.

2、水預冷：利用水將被冷卻食品從初始溫度降至到所需要的終點溫度的方法稱為水預冷方法。

2. Water pre cooling: the method of using water to cool the cooled food from the initial temperature to the desired end point is called water precooling.

3、真空預冷：依據水隨壓力降低其沸點也降低的物理性質，將預冷食品置于真空槽中抽真空，當壓力降低到一定數值時，食品表面的水分開始蒸發，吸收汽化潛熱，使食品自身被冷卻的方法就是真空預冷方法

3, vacuum pre cooling: Based on the physical properties of water is reduced with the decrease of pressure the boiling point, the pre cold food in a vacuum tank vacuum, when the pressure is reduced to a certain value, the food surface water evaporates, absorb the latent heat of vaporization, the food itself is cooling is vacuum pre cooling method

大多數冷庫安裝業內人士認為冷庫的溫度越低越好，冰存物的保存期限可以延長，但有時應依據各種物品所需要的保存溫度而定，以蔬果類，過低的儲藏溫度易導致凍傷發生，而肉類產品溫度低可保存較長時間。

Most industry insiders believe that the cold storage installation and the lower the temperature, the ice storage preservation period can be extended, but sometimes should be based on various items to save depending on temperature, with low temperature storage Vegetable & Fruit, easily lead to the occurrence of frostbite, and low temperature meat products can be preserved for a long time.

冷庫以經濟與能源觀點來考慮，就應以保存時間長久來選擇低溫冷庫儲藏溫度，如肉類在-18°C下可儲存4-6個月，在-23°C下可存儲8-12個月，因為肉類在5個月內就要到消費者手上，所以有時會考慮是否選擇-23°C的保存溫度，因此，冷庫安裝必須依存物的商品命周期，與其有效的保存環境來選擇合適的保存溫度。

In cold storage energy and economic perspective, it should be stored a long time to choose the low temperature cold storage temperature, such as meat in -18 ~ C can be stored in 4-6 months, -23 ~ C can be stored for 8-12 months, because going to the hands of consumers of meat in 5 months, so sometimes considered whether the choice of -23 DEG C temperature, therefore, must depend on the cold storage installation commodity life cycle, and the effective preservation of the environment to select the appropriate storage temperature.
