- Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate， and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator， make the drainage pipe in advance， and make U-bend and silica gel outside the storage.
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， the heat transfer coefficient will be reduced. Similarly， 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，Padre portPrice and installation of cold storage project， and the decline rate of warehouse temperature will be slowed down.
Padre portThe selection of the refrigeration system of the controlled atmosphere storage is mainly the selection of compressor and evaporator. The refrigeration system is the core of the controlled atmosphere storage， which is mainly composed of compression system， condensation system， evaporation system and regulating valve. In addition， there are auxiliary parts such as fan， duct and instrument. The whole refrigeration system is a sealed circulating circuit in which the refrigerant circulates， The compressor is the heart of the refrigeration system， which promotes the circulation of refrigerant in the system. The function of the condenser is to remove the heat from the compressed gaseous refrigerant and condense it into liquid refrigerant; The cooling methods of the condenser include air cooling， water cooling and the combination of air and water. Air cooling is only used in the refrigeration equipment of small-scale air-conditioned storage. The role of the evaporator is to provide cooling capacity to the air-conditioned storage. The evaporator is installed in the air-conditioned storage. The blower blows the cooled air to all parts of the storage. The air duct of large-scale air-conditioned storage is commonly connected with the evaporator to extend the air supply distance，Padre portHow much is the design and installation of cold storage， Make the storage temperature drop and even.
Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.
AtlauPolyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.
The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can"t drop down or drops slowly. Now， resulting in poor thermal insulation and thermal insulation effect a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall，Padre portQuotation of cold storage， It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.
- floor installation of cold storage: first level the floor， then install the floor， select a beautiful floor and put it in a conspicuous place， which will seriously reduce the local thermal insulation performance of the storage body.
Pressure leak test: the system pressure leak test is the same as the blowdown work sample， which is required to be carried out by air compressor.
The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade， and pay attention to the waterproof of the lamp.
originalProper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.
How to maintain the refrigeration compressor in the cold storage in order to prolong its service life and reduce the occurrence of faults in the use process. The refrigeration compressor in the cold storage needs regular maintenance. Here we introduce the maintenance of the compressor in the cold storage.
There are many application scenarios of cold storage， which are different. For a long time， it provides various cold storage installation cold storage installation， cold storage construction， fruit preservation cold storage， medical cold storage， on-site settlement， honest operation， and has offices all over the country for long-term cooperation. Different purposes， functions and designs， so what needs to be understood in cold storage design?
Cold storage has strong stability. Polyurethane foam technology 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， the characteristics of the cold storage still do not separate and fall off from the carrier layer and remain stable under normal conditions.
StatisticsThe ultrasonic town is a patented technology with a shaped energy cover， which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?
The distribution box is installed horizontally and vertically， the ambient lighting is good， and the room is dry， which is convenient for observation and operation.
Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction)， the size changes often reflect bubble cracking or falling off， and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing， more emphasis is placed on the selection of high quality materials: special energy polyether compound use， so that the foam body mesh structure， greatly improving the foam low temperature resistance. At present， polyether commonly used in spraying materials contains a large number of functional components， and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage， and the reaction is complete， so that the polyether maintains a high reaction rate (that is， it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material， reduce the bubble closed hole rate， achieve the effect of stable size， but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.
Padre portCommissioning cold storage. After all parts of the cold storage are installed and connected， adjust the value of the cold storage， the cold storage can reach the predetermined temperature， and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge， as well as some after-sales training.
When installing polyurethane insulation board， ensure that its surface is smooth and flat without scratch and warpage.
Compression refrigerator is commonly used， which is mainly composed of compressor， condenser， throttle valve and evaporation pipe. According to the way of evaporation pipe device， it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe， it will directly absorb the heat in the warehouse and cool down.
