Moreover, polyurethane does not produce harmful gas at high temperature.The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.cholecystitis,Air tightness test: system air tightness test, also known as leak detection process, is the last link of commissioning. This work can be divided into pressure, vacuum and ammonia filling leak detection stages.Polyurethane 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.ZagrebThe 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, the deterioration of foam performance is also a very important index. When the white material is prepared and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, 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.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, plus the row to row corridors, 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, packaging and combing room, special tool warehouse, loading and unloading platform, etc.

In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M,cholecystitisInstallation of cold storage, and the polyurethane top storage plate (mm thick) has a span of m.The valve temperature sensing package shall be fastened at the evaporator outlet with a metal clamp for mm & mdash; mm, tightly wrapped with double-layer insulation.The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time,It will still decrease. The humidification amount will decrease by % at degrees.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.Cold storage board, compressor, and other components in the cold storage can reasonably adjust the evaporation and condensation temperature, so as to improve the reduction of power consumption and reduce the production cost. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage, quality assurance, professional, timely supply and high cost performance. It has become the preferred brand for many wire products. Welcome to buy! Save more resources.

During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.Market trendDuring the installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process, so as to waste resources and increase the cost.The gap between the cooling fan and the storage plate shall be greater than the thickness of the cooling fan.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.cholecystitis,It is required to set up a special tally room (area), and the temperature of the tally area is usually controlled at ~ + ℃.Artificial refrigeration keeps the room at a constant temperature. The walls, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, which can save land; When the storage capacity is the same,cholecystitisFruit preservation cold storage installation company, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc.
