The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.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,An air duct is generally set in the vegetable cold storage. The air flow from the upper air duct mouth blows to the wall and the lower product line, returns to the middle, is absorbed by the lower part of the evaporator, and the evaporator drains and returns to the air duct again.The insulation board of the cold storage adopts polyurethane double-sided color steel plate. The main effect of this cold storage insulation board is good sealing performance, insulation effect and moisture-proof effect, so as to ensure the refrigeration effect of the cold storage. The electric cold storage door is adopted for the cold storage door, and the cold storage management personnel can timely and effectively open and close the door when entering and leaving, so as to avoid the loss of refrigeration capacity of the cold storage.Kongens Lyngby,Cold storage is fireproof, flame retardant and high resistance. Professional 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.Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, so we try to use screw parallel units. The great advantage of this unit is that it can turn on all equipment,MatiguaFruit preservation cold storage installation company, just like the shift at work, so that the compressor can work and rest in turn.
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?After the installation of the controlled atmosphere storage, which plays a key role in the use of the controlled atmosphere storage.The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.High value,Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.During installation, the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.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.
The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced,MatiguaInstallation of drug cold storage, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.Installation requirements,Moreover, polyurethane does not produce harmful gas at high temperature.The logistics cold storage project in the tally area belongs to the type of cold storage with frequent goods in and out and large quantity. Therefore, in order to keep the temperature fluctuation in the warehouse small, especially low-temperature logistics refrigerators, usually set up a special tally area according to business needs, and the temperature of the tally area is generally ~ ℃. In addition, a transfer room will be set in the logistics cold storage to avoid the loss of refrigeration capacity caused by frequent opening and closing of the cold storage door, or unqualified temperature and serious frosting.During the installation of cold storage board in cold storage, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process,The overall construction achievements of the cold storage project have been put into use and the service life can reach years.Cold storage, compressor overload, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
