Because polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.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,Villa Canales How many square meters are installed in the cold storage, 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.Villa Canales The fresh-keeping storehouse is generally composed of maintenance structure and refrigeration equipment. It is mostly cooled by compressor, and the gasification temperature is very low as coolant, so that it can evaporate under low pressure and mechanical conditions, such as food industry so as to achieveThe construction of small cold storage is widely used in life, manufacturing industry, etc. since cold storage is so widely used, do you know cold storage? Especially the construction process and steps of cold storage. Understanding the construction process and steps of cold storage is helpful for all links of cold storage maintenance.Vukovar,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.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, and the temperature will disperse which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.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.

Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.After the welding of the whole system, the air tightness test shall be carried out, and the high-pressure end shall be filled with mp nitrogen. Nitrogen charging MP at low pressure end. During pressurization, conduct leak detection with soapy water,Villa Canales Cold storage manufacturer installation, and carefully inspect all welded junctions, flanges and valves, so as to keep the pressure from falling off after the completion of simplicity.Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, and can bring harmful gases such as carbon oxide out of the warehouse during storage.Sincere service,The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, 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, 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.In order to prevent damage to the cold storage, it is necessary to lay some foam on the floor of the cold storage tank.It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.

With the increasing use of cold storage, cold storage board as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.How many?,Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.The high temperature and high pressure of the compressor of the wholesale condenser of the fresh-keeping warehouse as the heat sink and heat exchanger needs to be dissipated and heat exchanged through the condenser, mainly to condense the refrigerant. The high-pressure temperature can reach Baidu, and the temperature will drop to degrees after condensation.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition, it shall be conducive to production, construction and dry ceremony.Villa Canales ,It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator, which has the advantages of low temperature resistance, low energy consumption and long service time, It can effectively save the operation cost of cold storage.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.
