The 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, 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.
If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.
USA.Mark the name on each filter.
During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.
.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.
Wall and floor fixtures shall start at corners. According to the plate layout drawing, transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, drill a hole at the corresponding elevation in the middle of the plate width. When drilling, the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, tighten the angle iron, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels, foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.
The cold storage shall be regularly overhauled and maintained so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.
The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.
After evacuation fill the refrigerant into the liquid storage to 70% of the standard filling volume & mdash; 80% by weight, then run the compressor and add gas from low pressure to sufficient volume.
Before the acceptance and delivery of the project, the board surface shall be wiped clean. If there is any scratch, it shall be treated. There shall be no obvious scratch on the board surface.
technological innovation.The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, it needs to be checked in time.
Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.

The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, it needs to be checked in time.
Discount.More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.
The electrical contacts shall compress the wire connector and the main wire connector of the motor, which shall be clamped with a wire clamp, and tin shall be hung if necessary.
There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.
USA.Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project, we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and 0mm galvanized standard floor plate.
Acid disinfectant can be used for mold removal and disinfection of quick-frozen warehouse.
We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R11 gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.
