During production in the production workshop, the unit weight of Pu warehouse board shall not be less than the unit weight required by the project, not less than & plusmn; kg/m.Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, because the temperature difference inside and outside the board is large, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.ArthurMeasure the power supply voltage according to the technical requirements for fluorine filling and commissioning of refrigeration system.The importance of regular oil discharge, descaling and air discharge in the refrigeration system of the warehouse.Hajdunanas,The ground insulation of small, medium and large cold storage is different, which is closely related to the purpose,ArthurInstallation cost of fresh-keeping cold storage, 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,ArthurPrecautions for medical cold storage, medium and large cold storage? How to do better?There are many application scenarios of cold storage which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?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.

Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.The location of fresh-keeping warehouse installation shall be in a stable and convenient place; (if it is a local fruit farmer, it should be installed near the fruit source)There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, and maintain good natural ventilation. 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.Where is good, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example, at present, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment, it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.With the rapid development of modern commerce, the original cold storage for the purpose of product storage can no longer meet the rapid, accurate and small batch circulation needs of modern commodities. Therefore, the logistics center cold storage cold chain for the purpose of product distribution came into being and developed rapidly, playing a more and more important role in the commodity circulation chain. What are the characteristics of the rapid development of cold storage construction?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 ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).

During the early operation of the refrigeration unit, carefully observe the oil return of the compressor and keep it clean. If it is found that the oil level is not clean enough or the oil level drops, replace it with new oil in time, so as to avoid bad compressor and reduce the service life of the compressor.Marketing Department,Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.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.In the process of realizing your dream, you must remove all the influences. It is very important to recognize that when these beautiful refrigerators are built in the villa room,In fact, there are some unique installation skills when installing the cold storage? The cold storage installed according to these skills is often short in both effect and quality, and the specific installation skills of the cold storage will also make some relatively detailed introduction for you in the following article. When installing the cold storage, you should install it from the corner first. Later, and tighten the angle iron parts until there is a hole on the insulation boardThermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m make a hole in the middle of the insulation board, the thermal conductivity is only . ~ .w / (m.k), which is the lowest among all thermal insulation materials at present.Initial stage of cold storage equipment
