Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, loading and unloading platform, etc.Eskipulas,If the warehouse is relatively small and you want to transform a miniature fruit fresh-keeping warehouse, you should ensure that the height in the warehouse is at least meters, because the top of the cold storage and the top of the warehouse should reserve a height of at least cm.Cold storage is fireproof, flame retardant and high resistance. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other special products, 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.Jaszbereny,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.In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.
As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.The door hinge, door handle and anti-theft lock of the door of the freezer shall be greased on time according to the specific situation.Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.Free consultation,General quick-frozen warehouses are mostly cooled by refrigeration mechanism with low gasification temperature (ammonia or Freon)Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface,EskipulasTea cold storage, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, 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 the goods in and out and operation management are not as convenient as single-layer cold storage; With the development of the floor load capacity the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance, the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.
Thermal insulation performance of thermal insulation materials for food cold storage the requirement of polyurethane thermal insulation materials for cold storage is thermal insulation performance, and the quality of thermal insulation performance cannot be observed before it is really put into use. It is too late to observe the difference between power consumption. In this large number of experimental tests, strict material selection is carried out in order to achieve this goal: using structural amine ether to reduce thermal conductivity and improve thermal insulation effect; Reduce the water content of various raw materials and formulas as much as possible to avoid deterioration of thermal insulation performance caused by water foaming; Polyether: the product of a large processed factory after strict postprocessing is compared with the polyether of small factory without postprocessing. The foam cell has high uniformity of foam pores and thin wall of foam holes and its heat preservation performance is obviously better than that of ordinary foam with thick wall and big hole. The use of the tasteless amine catalyst can effectively adjust the balance between foaming and gel reaction, so that the interlayer skin of the sprayed coating is thinner which is beneficial to the performance of the thermal insulation material of the cold storage. Ordinary polyester polyols are not used.Good quality,The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done, otherwise the temperature in the cold storage often fluctuates frequently due to poor insulation performance, which affects the quality of stored goods. So,EskipulasPrice of cold storage installation, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?The volume of the controlled atmosphere warehouse the size of the controlled atmosphere warehouse shall be calculated according to the volume occupied by the storage products stacked in the controlled atmosphere warehouse, plus the aisle between rows, the space between the stack and the wall and ceiling, and the gap between the packaging. After determining the capacity,EskipulasHow to make a small cold storage, the length and temperature of the controlled atmosphere warehouse shall be determined. The design of the controlled atmosphere warehouse shall also consider the necessary auxiliary buildings and facilities, such as workshop Packing and sorting room, tool warehouse and loading and unloading platform, so that the quality of controlled atmosphere warehouse can be guaranteed.The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.Eskipulas,Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice a reasonable design scheme should be given according to local conditions. For example, the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation. - 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.Commissioning cold storage. After all parts of the cold storage are installed and connected the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.
