polyurethane does not produce harmful gas at high temperature.
Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.
kelowna.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.
The refrigeration equipment in the fresh-keeping environment of the quick-frozen warehouse mostly adopts the single-stage compression refrigeration system, which can be ceiling type. If the number of warehouses is small and the volume does not exceed 500 cubic meters, the refrigeration mode of the warehouse machine can be considered. If there are a large number of warehouses the mode of multiple heads in parallel can be considered.
.Frozen and refrigerated storage began to change to shelf and pallet storage to complete the goods according to & ldquo; First in first out & rdquo; It is conducive to improve the quality of commodity storage and reduce loss.
Compression refrigerator is commonly used. It is mainly composed of compressor, 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.
The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, so as to facilitate the use of concrete to cover the connector in the future.
Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.
The suction pressure of fresh-keeping storehouse remains unchanged, and when the exhaust pressure increases, the exhaust temperature increases; If the exhaust pressure remains unchanged, when the suction pressure decreases, the exhaust temperature also increases. Both cases are caused by the increase of compression ratio of fresh-keeping warehouse. Too high condensation temperature and exhaust temperature of fresh-keeping warehouse are unfavorable to the operation of compressor, which should be prevented. Too high exhaust temperature will dilute the oil and even carbonize and coke, which will worsen the compressor conditions of the fresh-keeping warehouse.
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.
analysis.During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.
The height of the warehouse, the horizontal and vertical of the warehouse shall be designed according to the refrigeration, refrigeration equipment, transportation and stacking conditions. The selection of insulation board is very important for Guangdong cold storage. At present, the vast majority of cold storage use polyurethane insulation board. What are the characteristics and advantages of polyurethane insulation board?
The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.
The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.
ranking.Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storage, set the parameters on the refrigerator. During use the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include 100mm, 120mm, 150mm, 175mm and 200mm polyurethane thermal insulation boards, color steel tiles, stainless steel plates, salt thick steel plates, polyurethane spraying etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble, and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases, and it is also easy to deform and damage the appearance.
If the engineering design of logistics cold storage should bear the important responsibility of low-temperature storage and transportation, in addition to paying attention to the planning of the above basic functions, KFC refrigeration suggests that enterprises can also configure the classification, scale, unpacking, packaging, etc. of large packaging, product portfolio packaging, trademark, label pasting and supporting tools according to business needs So as to better improve the quality of refrigeration distribution center and realize greater value return.
Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid without hollow feeling, load-bearing, antifreeze, moisture-proof, etc.
kelowna.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.
Clean and professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage have stable performance, safety, reliability and maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.
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, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.
