SalaberrydeValleyfieldInstallation of small cold storageIndustry Research Report

Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.

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, 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.

SalaberrydeValleyfield.Clean the bearing and replace the oil in the centrifugal pump, and the vibration of the shaft.

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.

.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, the drainage problem must be considered, and the following 8 points should be paid attention to during redesign and installation.

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.

The temperature is too high,SalaberrydeValleyfieldBuy cold storage installation, the condenser is blocked in the cold storage, the compressor is overloaded, there is a lack of refrigerant, the low pressure is too low, the air intake is too large, 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.

Meteorological elements include local average temperature, relative temperature and summer monsoon frequency.

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, 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.

Good quality.When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.

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.

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.

Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel, unloading platform, etc.

Industry management.1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north,SalaberrydeValleyfieldInstallation price of small cold storage, the drainage pipe shall be insulated).

The area of wires in the conduit shall not exceed 50%.

Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be 10 ~ 12 seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; 1TR time relay is broken (relay unit).

SalaberrydeValleyfield.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,SalaberrydeValleyfieldIt costs a lot to install the cold storage, while the ground needs to be insulated separately. At present, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.

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, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.

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.
