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, what is the difference between the ground insulation of small, medium and large cold storage? How to do better?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, special tool warehouse loading and unloading platform,The cold storage construction in the site selection undertakes the circulation of low-temperature goods. Therefore,chatelet How much does it cost to install a small cold storage, when selecting the site, priority should be given to the transportation convenience of the cold storage construction site, such as close to roads and railways. 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.The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.Canete,Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.Polystyrene foam: polystyrene foam is a new type of synthetic thermal insulation material. It is a kind of plastic with small density, light weight, strong heat insulation effect and excellent low temperature resistance. However, due to its cold shrinkage, it is not very convenient for installation.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, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing, firmness and frost resistance.No dirt shall be accumulated on the equipment of the fresh-keeping warehouse, otherwise the warehouse plate of the frozen warehouse will deform and endanger the thermal insulation characteristics, and keep the channels around the frozen warehouse unimpeded. Only by ensuring excellent heat removal and refrigeration can it be excellent. The place where the freezer is placed shall be kept dry,chatelet Preservation technology of vegetables in cold storage, clean, free of inflammables and ensure that there is no risk of cutting. Objects shall not be stacked in front of the air conditioning evaporator to prevent endangering the actual effect of refrigeration.Cold 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, 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 storageLet's see,All wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.Installation of refrigeration equipment. The refrigeration system of the cold storage includes evaporator and units outside the cold storage. All equipment shall be installed in accordance with the construction specifications, and corresponding protection measures shall be taken for the installed equipment.
When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, and the opening and drilling shall be carried out after review; The inlet hole, liquid inlet hole, return hole water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of mm and mm outside.Variable cost,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 general installation of air-conditioned storage will use air coolers for refrigeration. In this case, the temperature of such a controlled atmosphere reservoir may be too low. It is suggested that the unit can adjust the scale a little larger in the process of temperature setting.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm, the condensation temperature will rise by ℃ compared with the original temperature, and the power consumption will increase. When the refrigeration system is mixed with non condensable gas and its partial pressure reaches .mpa, the power consumption will increase by about . It can be seen that it is coldchatelet ,Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking,chatelet Cold storage board installation, every ℃ increase in the evaporation temperature of the cold storage can save energy by ~ . 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.Different food processing technical processes for the construction of cold storage are combined with local urban planning. The construction of cold storage is the design requirements and construction of cold storage, but also ensures its transportation facilities: within the construction scope, a reasonable overall layout, saves land and reduces costs.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, the refrigeration capacity of the system will also decrease
