The water tank is designed to be separated from the machine body and is double-layer. It will not drip due to condensation caused by internal and external temperature difference. It can be interlocked with the refrigeration system, it will not be humidified during refrigeration to prevent serious frosting of the fan.
Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate the compressor line is disconnected, the fuse is blown, the thermal relay acts, the high-voltage switch acts, the compressor is locked, the line is falsely connected or loose. Fault phenomenon: it stops in a short time after the drying motor, and the environment
Bytca.Once there are impurities in the controlled atmosphere storage system, it will affect the sealing performance of suction and exhaust valve plates and valve seats, which will seriously affect the refrigeration capacity of the controlled atmosphere storage.
The service life of polyurethane cold storage insulation material foam is: besides the basic performance of the initial stage of polyurethane foam, the deterioration of foam performance is also a very important index. When the white material is prepared, 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, but generally disappears after a few days,BytcaHow much is the fruit and vegetable storage, and then maintains the stable performance of cold storage insulation materials for a long time.
.General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)
The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.
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.
The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.
Check whether the compressor phase current is stable.
Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.
For more, please check.Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low, but it has a great impact on the cost of quick freezing warehouse and later use cost. The electricity bill is often an important expenditure item in the later stage. The design scheme of the show can greatly reduce the power consumption of the quick freezing warehouse. The selection of the back sunny side of the quick freezing warehouse the selection of the thickness of the thermal insulation board should be appropriate, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips,BytcaMedical cold storage, such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.
Where do you need to build the refrigerator, the size of the refrigerator or the storage capacity (size, storage capacity, ton, 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, it is the selection of raw materials, such as refrigeration compressors refrigeration units, industrial cooling fans / pipe slots, coolers, doors, temperatures and other refrigeration equipment.
Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.
During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than 40 & plusmn; 2kg/m3.
Honesty and mutual benefit.Some cold bridge prevention measures shall be taken at the joints between polyurethane insulation boards.
Protective fence shall be set around the door of the controlled atmosphere storage with eye-catching signs.
Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.
Bytca.There are many kinds of cold storage. According to the material, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is 0.5mm and 0mm, without color requirements; The thickness of salted steel plate is 0.5mm, without color requirements; The thickness of PE paint baking board is 0.5mm, 0.8mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the 150 mm storage plate is 150 mm, and the thickness of the vertical plate is 160 mm and 100 mm, which is suitable for the insulation conditions of - 25 ℃ ~ - 45 ℃; 100mm storage plate: the thickness of the ceiling plate is 100mm and the thickness of the vertical plate is 110mm, which is suitable for the thermal insulation conditions of 0 ℃ ~ - 25 ℃. The thickness of the ceiling plate and the vertical plate of 60mm storage plate is 60mm, which is suitable for the thermal insulation conditions above 0 ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = 900mm, heaven and earth plate width WB = 980mm, vertical angle plate W1 = 790mm, W2 = 840mm, W3 = 740mm and W4 = 880. The dimensions of non-standard plates are different from those of Wa,BytcaConstant temperature medical cold storage, WB and W4.
The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed, the butt joint shall be filled with foaming material, and the 80mm wide color steel plate shall be sealed at the butt joint with pull riveting.
In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials 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. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.
