When the cold storage is built, the diffusion of water vapor and the infiltration of air shall be prevented. When outdoor air invades, it will not only increase the cold consumption of the cold storage, but also bring moisture into the warehouse. Moisture condensation will damp the heat insulation structure and freeze and damage the cold storage structure. Therefore, it is necessary to set moisture-proof and heat insulation layer, professional cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, sell well at home and abroad, and have a long service life! Products lead the wire industry. Welcome to inquire, so that the cold storage building has good sealing, moisture-proof and steam isolation performance.It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.Harlem,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, the temperature will rise. For this reason, 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.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.Nkoteng,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,HarlemCold storage engineering installation design, 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,HarlemWhich is a good place to install fruit and vegetable cold storage, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation cold storage installation, fruit fresh-keeping cold storage cold storage construction, medical cold storage, complete products, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However, the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.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.

Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.The electrical contacts shall compress the wire connector and the main wire connector of the motor, which shall be clamped with a wire clamp, and tin shall be hung if necessary. - precautions for floor installation of cold storage: the floor shall be installed flat, the drainage pipe shall be insulated).Superior quality and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north,During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, and each top warehouse plate shall be riveted in two rows; If the lifting point type is adopted, the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.

Improper adjustment or blockage of throttle valve, too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease, and the decline rate of warehouse temperature will also slow down.Manufacturing cost, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.Daily maintenance and management of fruits after Warehousing: timely the temperature and humidity in the cold storage, strictly control the temperature in the cold storage, timely eliminate the bad gas in the cold storage, and adjust the temperature and humidity of the cold storage according to the different requirements of different fruits on the storage environment. If long-term drying will affect the color of the fruit, consider using a humidifier to adjust the humidity in the cold storage. - precautions for vertical plate of cold storage: vertical plate displayHarlem,In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.
