SiquirresDesigRequirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, due to the good sealing of the quick freezing warehouse,LexingtonFayetteFrozen storage, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.
The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.
LexingtonFayette.The volume of cold storage the size of cold storage shall be calculated according to the volume occupied by the stacking of goods stored in the cold storage plus the corridor from row to row, the indoor space between the stack and the wall, and the gap between the ceiling and the packaging room. After determining the volume, the length width ratio of the cold storage shall be determined. When designing the cold storage, necessary auxiliary engineering buildings and equipment should also be considered, such as working intermediate, packaging and combing room, special tool warehouse and loading and unloading platform, so as to ensure the quality of the cold storage.
Goods in and out frequently, throughput
.Improper adjustment or blockage of throttle valve, the refrigerant flow is too large, the evaporation pressure and evaporation temperature also increase, and the decline rate of warehouse temperature will slow down; At the same time, when the throttle valve is opened too small or blocked, the refrigerant flow will also decrease, the refrigeration capacity of the system will also decrease,LexingtonFayetteProfessional installation of cold storage, and the decline rate of warehouse temperature will also slow down.
The combined cold storage door starts frequently or does not start for a long time,LexingtonFayetteCold storage and fresh storage, or does not stop for a long time, or stops before the storage temperature reaches.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.
The air suction surface of the condenser shall be kept more than 400mm away from the wall, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, the stored goods must be in strict accordance with the relevant regulations. The goods should have a certain distance from the ground and wall of the cold storage. When stacking the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be 100 cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.
It is built in the room. There shall be excellent drainage pipe standards around the cold storage, the soil temperature shall be low, there shall be interlayer under the cold storage, and good natural ventilation shall be maintained. Maintaining dryness is very important for the cold storage. In addition, before the construction of the cold storage the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.
These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, the cold storages using their white materials have significantly lower power consumption than those using other white materials.
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, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.
where.Relative humidity maintenance of quick-frozen warehouse: humidification of quick-frozen warehouse is very important, from centrifugal humidification to high-pressure micro fog humidification, gas-water mixed humidification, to the current ultrasonic humidifier. The utility model has the advantages of small particles, uniform humidification, no freezing and blocking, and no dirty blocking. The air conditioning humidifier we produce is specially designed for all kinds of vegetable and fruit quick freezing warehouses, which is essentially different from other humidifiers in the market: fully closed circulation, that is, take the gas in the warehouse, return to the warehouse through the humidifier and isolate it from the outside air.
Therefore, the cold storage also needs regular maintenance every year, so as to ensure its stable operation.
Moreover, polyurethane does not produce harmful gas at high temperature.
LexingtonFayette.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.
The evaporator surface is too thick or too much dust, and the heat transfer effect decreases: another important reason is that the heat transfer efficiency of evaporator is low, which is mainly caused by excessive frost or excessive dust on the evaporator surface.
After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage. Professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, advanced technology, strict testing, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.
