During 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, so as to waste resources and increase the cost.
Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, cubic meter, frame, box); What products are stored in the built cold storage? The actual storage temperature, storage time and setting temperature can be indicated by specific regulations; If your cold storage becomes larger, you need to master your individual storage volume, the temperature of goods in and out of the warehouse, the frequency of opening and closing the door, etc. If this is clear, it is the selection of raw materials, such as refrigeration compressors, refrigeration units, industrial cooling fans / pipe slots, thermal insulation materials, coolers, doors, temperatures and other refrigeration equipment.
Naranjo.After the welding of the whole system, the air tightness test shall be carried out, and the high-pressure end shall be filled with 8mp nitrogen. Nitrogen charging 2MP at low pressure end. During pressurization, conduct leak detection with soapy water, and carefully inspect all welded junctions, flanges and valves, so as to keep the pressure from falling off after the completion of simplicity.
Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.
.It is suitable for the freezing processing and storage of food, and manual refrigeration to keep the indoor temperature constant. 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, the surface of the external wall of the cold storage is painted white or light color.
With the increasing use of cold storage, cold storage board, as an important structure of cold storage is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.
For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation, but its energy consumption is very large in the use of cold storage. How can we solve this problem?
Cold storage construction: which one is suitable for you? Which one is suitable for you?
Frozen and refrigerated storage begins to shift to shelf and pallet storage in accordance with & amp; amp; amp; ldquo; FIFO & amp; amp; amp; rdquo; This is conducive to improving the quality of commodity storage and reducing losses.
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, installation of cold storage,NaranjoWhat cold stores are installed, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other products, which have a complete variety, 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.
Packaging strategy.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,NaranjoCold storage large cold storage, 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 wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, the cold storage door should be closed in time, So as not to expose more air conditioners, the system cooling system will also be turned on. When the temperature returns to normal,NaranjoFresh vegetables and fruits cold storage, it will be automatically turned off.
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.
Recommendation and consultation.At ordinary times, users should check the sealing degree of the gap of the cold storage and notify the cold storage for maintenance in time if damaged parts are found.
Another point is the ground maintenance measures in the wholesale of large fresh-keeping warehouses., Because the wholesale floor of large-scale prefabricated fresh-keeping warehouse is also a thermal insulation board, there will be a lot of ice on the ground in the process of use, so when cleaning these ice layers, you should pay attention not to beat them with a hammer or shovel, because it will damage the thermal insulation board on the ground. If the thermal insulation board is damaged it will affect the thermal insulation performance of the wholesale of fresh-keeping warehouse.
Because polyurethane sheet has excellent thermal insulation performance, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.
Compression refrigerator is commonly used. It is mainly composed of compressor it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
Naranjo.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, condenser, 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.
Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.
