HoustonCold storage design and installation plant,

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, 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.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam,HoustonDesign of low temperature cold storage, the deterioration of foam performance is also a very important index. When the white material is prepared, the surface of some polyester materials can make the foam have better toughness and impact resistance, but it will become brittle after use for a long time in the cold storage, and will no longer resist impact and collision. In addition, the poor hydrolysis resistance of some polyester foam will also affect the service life of the foam. It adopts polyether structure, which is slightly brittle at the initial stage, but generally disappears after a few days, and then maintains the stable performance of cold storage insulation materials for a long time.Houston,Due to the slow cooling, all equipment will consume electric energy during operation. If the cooling is slow, the equipment will stop and cannot consume electricity, so the electricity charge will not be consumed. As a high energy consuming equipment, the daily power consumption of cold storage is relatively large. If the refrigeration effect is not good, the annual use cost will directly double several times. Moreover, if the equipment operates for a long time, the service life will be reduced accordingly, which is something users don't want to see.The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.Napier ,The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Cold storage construction: which one is suitable for you? Which one is suitable for you?Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.

Before the acceptance and delivery of the project,HoustonInstallation price of cold storage, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.For the installation of power distribution system, each contact shall be installed with wire number for maintenance.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.Where can I find it?,Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room quick freezing room, refrigeration room, channel, unloading platform, etc.The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and state of foam pores. It is not connected with each other and the obturator rate is more than %. It is a dense microporous foam material, and is not easy to permeate. It is an hydrophobic material.

When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.Quality assurance,When using the cold storage, try to keep the ground clean and professional cold storage installation,Ice cubes are always available in the cold storage. For small cold storage, the cost of using standby power supply or generator set is too high and the cost performance is low. In this case, some ice cubes must be always available in the cold storage. In case of power failure or refrigeration equipment failure, ice cubes can be used to maintain the temperature in the cold storage.Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.Houston, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, which can well meet the health needs.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operationCork board: cork board can be said to be a relatively primitive kind of cold storage. The thermal conductivity of cork board is relatively low, and it is easy to obtain, so it is not difficult to process, so it is generally used as the insulation board in some ordinary cold storage. If you want to pursue better thermal insulation performance, you have to look at the following materials.
