Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.
Aruba.The exhaust temperature of the compressor in the fresh-keeping warehouse can be read out from the thermometer on the exhaust pipeline. It is related to the adiabatic index, compression ratio and suction temperature of refrigerant. The higher the suction temperature, the greater the compression ratio, the higher the exhaust temperature, and vice versa.

.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m3, the thermal conductivity is only 0.018 ~ 0.024w / (m.k), which is the lowest among all thermal insulation materials at present.
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.
In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, according to the height of the cold storage, make a hole in the middle of the insulation board behind the angle iron parts

The wholesale evaporator of the fresh-keeping storehouse is used as a cold absorber for the wholesale of the fresh-keeping storehouse. The wholesale evaporator of the fresh-keeping storehouse is installed in the room of the cold-keeping storehouse, connected to the low-pressure end of the compressor, and has been installed for all kinds of cold-keeping storehouses with high prices nationwide for a long time. The cold-keeping storehouse is installed, constructed, fruit fresh-keeping cold-keeping cold-keeping cold-keeping, medical cold-keeping cold-keeping cold-keeping, The refrigerant dissipated by the compressor is used for evaporation and gasification, and instantly becomes low temperature and low pressure through the throttling device, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials, it is necessary to carry out the hygienic disinfection of cold areas regularly.
consumption.The construction of small cold storage is widely used in life such as food industry, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.
During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.
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.
2. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room 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, a button switch shall be added next to each refrigeration compressor.
technical service.No matter whether the food cold storage or quick-frozen storage is in use and relevant signs shall be set. If the mechanical panel is set in the main room, 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.
However, not all controlled atmosphere reservoirs can choose to adjust with a large depth, which still needs to be determined according to the actual needs of fans and places. We can adjust the energy-saving effect of the control fan from the production design link, so that the energy-saving effect of the hot air fan will be significantly improved.
Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, and the following 8 points should be paid attention to during redesign and installation.
Aruba.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.
1 - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.
Compression refrigerator is commonly used. It is mainly composed of compressor, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.
