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， the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project， we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature， attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment， use the volatilization of the refrigerant to immediately cool the air in the air， and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed， small heat conduction temperature difference and simple system software， so it is widely used.
Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area height and warehouse temperature of the cold storage on the basis of safety， science and rationality， from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.
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?
In use， the fresh-keeping warehouse must be maintained on time and scientifically. No matter how good the equipment is， without scientific use and maintenance its service life and effect will be discounted. Therefore， the fresh-keeping warehouse also needs to be maintained regularly every year， so as to ensure its stable operation.
The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator， which can effectively meet the refrigeration capacity of the refrigerator and ensure the refrigeration effect of the refrigerator. The refrigerator lamp adopts the special LED energy-saving lamp for the refrigerator， which has the advantages of low temperature resistance， low energy consumption and long service time， It can effectively save the operation cost of cold storage.
How much is itWatertight polyurethane rigid foam has low water absorption， good permeability to water vapor， and state of foam pores. It is not connected with each other， and the obturator rate is more than %. It is a dense microporous foam material， which is more dense than the surface of the air， and is not easy to permeate. It is an hydrophobic material.
The foundation of cold storage is affected by low temperature， it may even make the cold storage unusable. Therefore， in addition to the thermal insulation layer， the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading， unloading and transportation machinery and equipment. Therefore the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment， especially in the process of periodic freezing and thawing cycle， building structures are vulnerable to. Therefore， the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
Improper adjustment or blockage of throttle valve， too large or too small refrigerant flow: improper adjustment or blockage of throttle valve will directly affect the refrigerant flow into evaporator. When the throttle valve is opened too large， 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， and the decline rate of warehouse temperature will also slow down.
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， 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.
Pursuit of excellenceCold storage design steps: selection and preparation of cold storage location. According to the application characteristics， cold storage can be divided into sexual cold storage， retail cold storage and large-scale cold storage. When large-scale cold storage starts to build a planting area with more centralized hand supply，San jositoHow much is it to install a small cold storage， factors such as superior geographical location and contact with the market should also be taken into account. The cold storage should be located in a cool place without sunlight and frequent warm air. Small and medium-sized cold storage should be built in the room. cold storage
Fresh keeping storehouse is a building with artificial refrigeration to make the fixed space reach the specified temperature and facilitate the storage of goods. Fresh keeping warehouse wholesale can be widely used in food factories， dairy factories，San jositoSmall installation of freezer， factories， and so on. The following are the functions of the main parts of the fresh-keeping warehouse wholesale.
Cold storage is fireproof， flame retardant and high resistance. Professional cold storage installation， cold storage installation， cold storage construction， fruit preservation cold storage， old brands， price advantages and guaranteed quality. Polyurethane is a flame retardant self extinguishing material after adding flame retardant. Its softening point can be above degrees Celsius and will only be decomposed at higher temperatures. In addition， the ash formed on the surface of polyurethane will be in its foam， and this ash will help isolate the foam below. It can effectively prevent the spread of fire. Moreover， polyurethane will not produce harmful gas at high temperature.
San jositoThe installation of cold storage board is a link of the cold storage installation project. High price cold storage installation of various specifications， cold storage installation， cold storage construction， fruit preservation cold storage， medical cold storage. Waste merchants， industry， enterprises and power departments are welcome to visit and negotiate! The cold storage body and storage plate include: floor， vertical plate and ceiling plate. The installation of storage plates in different directions and precautions are as follows: enter the construction site， verify the construction situation according to the construction drawings， determine the equipment installation position， and then refer to the following specifications.
The type of cold storage to be built in the type of cold storage should be determined according to the type of circulating goods. For example， the cold storage that only circulates vegetables can only build a fresh-keeping cold storage， while the cold storage with refrigeration + freezing will be built if there are many types of circulating goods and great difference in storage temperature. As for the size of the cold storage it should be determined according to the type， quantity， frequency， cycle， whether to use shelf stacking and so on. For example， for fruits and vegetables packed in cartons， the storage capacity of -kg per cubic meter can be referred to， and the size of cold storage construction can be estimated in combination with the storage capacity rate of about .-..
