The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams, columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, etc., and the welded junction shall be moisture-proof and treated according to the drawing requirements.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.Nino,Before the warehouse is fixed with angle aluminum, it shall be sealed with glass glue and fixed with angle aluminum with solid pull Mao. The distance between pull rivets is mm. The distance between the upper and lower sides of the door is mm.The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.Waubzheh, 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 ground insulation of small medium and large cold storage is different, storage products and size of cold storage. Kuhua refrigeration reminds: ground insulation must be done which is closely related to the purpose, 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?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,NinoProfessional cold storage installation, 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.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.Vacuum test: after the pressure test of the fresh-keeping storehouse system is qualified, the vacuum leakage test of the fresh-keeping storehouse system can be carried out. The purpose is to improve the air tightness under the vacuum condition of the fresh-keeping warehouse and prepare the conditions for the ammonia filling of the fresh-keeping warehouse system.Polyurethane with good fire resistance and flame retardancy is a kind of refractory and self extinguishing material after adding flame retardant. In case of fire, it can be carbonized, unlike flow burning and flashover like extruded board, which can effectively prevent fire spread. In particular, it can be sealed as a whole after systematic fire prevention treatment to form non combustible products.total cost,Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.Another reason is that there are many refrigerants in the system. In this case, repair the found part, and then fill in sufficient refrigerant.For water-cooled units, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.
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.Installation works, height and warehouse temperature of the cold storage on the basis of safety science and rationality,NinoCold storage and freezing of drugs, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.Condensation pressure if the condenser has poor heat transfer, the condensation pressure will increase and the cooling power will decrease. For cooling, power consumption increases. If the configuration of the cooling system is too small, the heat transfer capacity will be insufficient, resulting in high condensation pressure.Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing,NinoGeneral cold storage installation, antifreeze, moisture-proof, etc.Nino,The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even in the work, the water temperature is lowSuggestions 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.
