There are many kinds of cold storage. According to the material， it can be divided into color steel plate， stainless steel plate and salted steel. Among them， color steel plate has strong anti rust ability， but stainless steel plate has strong anti rust ability， while salted steel has both beautiful appearance and anti rust ability. According to the layout， it is divided into flat plate and wave plate. The former is flat after the surface material is formed， and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials， the thickness of stainless steel is .mm and mm， without color requirements; The thickness of salted steel plate is .mm， without color requirements; The thickness of PE paint baking board is .mm， .mm ivory white， titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm， and the thickness of the vertical plate is mm and mm， which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm， which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm， which is suitable for the thermal insulation conditions above ℃. In fact， it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate， including standard plate vertical plate width wa = mm， heaven and earth plate width WB = mm， vertical angle plate W = mm W = mm， W = mm and W = . The dimensions of non-standard plates are different from those of Wa， WB and W.

Padre portEvaporator which is not only an exchanger for refrigeration and cooling， but also a very important device. Its task is cooling. It is mainly used for refrigeration and heat absorption in cold storage. During long-term operation， the fins of the evaporator will also be covered with dirt， most of which are pasted by some sundries of the product，Padre portHow much does it cost to install a small cold storage， plus dust and other things， but reaching a certain thickness will affect the cooling， resulting in poor refrigeration. Normally， it should be cleaned with special cleaning agent for the evaporator.
General quick-frozen warehouses are mostly cooled by refrigeration mechanisms， so as to absorb the heat in the warehouse， so as to achieve the purpose of cooling and reduction.
ChancreIn order to prevent damage to the cold storage， it is necessary to lay some foam on the floor of the cold storage tank.
The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel， which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.
Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices， and the product quality is relatively large. However， it is not high-quality or good goods. This is the result of long-term cooperation.
The ground insulation of small， medium and large cold storage is different， which is closely related to the purpose， storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done， otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance， what is the difference between the ground insulation of small， medium and large cold storage? How to do better?
Before the warehouse is fixed with angle aluminum， it shall be sealed with glass glue and fixed with angle aluminum with solid pull Mao. The distance between pull rivets is mm. The distance between the upper and lower sides of the door is mm.
What should be considered in building a cold storage? In these aspects， food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage， meets the needs of refrigeration technology，Padre portCharge for cold storage， convenient production，Padre portHow much is the general cold storage installation， energy saving and cost reduction. What problems should be considered in the construction of food cold storage?
middlemanEmergency measures during the use of the medical cold storage project， it may also encounter power failure or power failure. In fact， most medical cold storage projects will be equipped with emergency equipment， so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal， the cold storage door should be closed in time， So as not to expose more air conditioners， resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit， the system cooling system will also be turned on. When the temperature returns to normal， it will be automatically turned off.
Core tip: in the cold storage project， only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation， and is not prone to failure， convenient use and management and long service life.
Fire retardant， flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than ℃， and it will decompose only at higher temperature. In addition， polyurethane forms carbon deposits on the surface of the foam， which helps to isolate the foam below. It can effectively prevent flame spread.
During the use of cold storage， attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate， which will seriously reduce the local thermal insulation performance of the storage body.

The stacking and arrangement of cargo stacks in the controlled atmosphere warehouse have a great impact on the air circulation. A basic principle of air flow is to take the path with low resistance to obtain large air flow. If there is a dead corner caused by stacking obstruction and air circulation is difficult， there shall be gaps between the cargo stacks and between the cargo stacks and the wall. The stacking arrangement of the cargo stacks shall be coordinated with the ventilation arrangement.
The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is， under the unfavorable local temperature and humidity conditions， it can bear various internal and external combined loads such as wind force self weight and normal collision， and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
Padre portMore and more people begin to build cold storage， and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.
Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface， that is， the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials， while the ground needs to be insulated separately. At present， the common operations in the market are: laying the ground with XPS extruded board， and then pouring concrete or reinforced concrete.
If there is more air or refrigerant oil in the evaporator， the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube， if there is more air in the heat transfer tube， the heat exchange area of the evaporator will be reduced， the heat transfer efficiency will be significantly reduced， and the decline rate of warehouse temperature will be slowed down.
