During the installation of polystyrene storehouse, the Perpendicularity Error of wall plate shall be corrected while the top storehouse plate is installed. The length of the top warehouse plate shall be mm shorter than the surface of the wall plate. After the installation of the top warehouse plate, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.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.Stropkov,Whether the warehouse can drill through the wall. The construction and installation of cold storage shall be like the installation of air conditioner, and the external unit shall be connected with the unit in the cold storage.The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.Chinhoyi,Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes, and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner, which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Another reason is that there are many refrigerants in the system. In this case, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, special tool warehouse, loading and unloading platform, etc.

Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.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.For water-cooled units, the turbidity of cooling water shall be frequently,StropkovInstallation of cold storage works, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.reformWall and floor fixtures shall start at corners. According to the plate layout drawing, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt drill a hole at the corresponding elevation in the middle of the plate width. When drilling, tighten the angle iron the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line,StropkovHow much is the cold storage, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, 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.The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, 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 resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.

Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.High quality brand,No matter whether the food cold storage or quick-frozen storage is in use, it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.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.The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.Stropkov,Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, and the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course,StropkovInstallation price of cold storage, more important is the choice of refrigeration system. For example, at present the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment, it is necessary to calculate the data for the installation of cold storage, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room
