雪锐龙鲜肉柜冷柜如何按类型使用

时间:2018-06-23 15:27 作者:admin

  鲜肉柜可以分为水冷却式、风冷式、水和空气联合冷却式三种类型,其实这三种类型是有很大的区别的,存储的食物不同,温度范围不同、工作原理不同。

  1.水冷却式:是以冷藏柜中的冷藏器用水作为冷却介质。超市鲜肉柜使 高温高压的气态制冷剂冷凝的设备。

  2.风冷式:利用空气作为冷却介质向发电机定子和转子绕组以及定子铁心进行冷却的系统。该系统通常有开式通风和闭式循环两种冷却方式。

  3.水和空气联合冷却式:冷凝器采用水和空气联合冷却方式的冷凝器包括淋水式冷凝器和蒸发式冷凝器两大类。在这两类冷凝器中,制冷剂在管内冷凝,冷却水喷洒在传热管外。在淋水式中,制冷剂放出的热量大部分依靠空气自然对流带走,少量的热量是由水的汽化吸热带走。

  如超市中的冷柜大多是风冷式的。风冷式冷柜都是微孔式送风设计,冷柜里面还有超大蒸发面积铜管,制冷速度快,不易风干能够充分保证食物中的水分和营养物质,食物的保鲜展示效果好。这种鲜肉柜一般用来保存熟食或者新鲜的肉类。存储饮料的鲜肉柜常用冷凝器是一个制冷剂向外放热的热交换器。自压缩机经油分离器来的制冷剂蒸气进入鲜肉柜冷凝器后,将热量传递给周围介质水或空气,自身因受冷却凝结为液体,从而使得鲜肉柜内部温度降低,达到保存饮料的效果。

  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.
