Military Ship Refrigeration Equipment Application

  Military industry, referred to as military industry, is an industrial aspect related to the army or war (combat readiness). In China, military-industrial enterprises mainly refer to industrial departments and factories that mainly serve national defense construction and directly provide the troops with weapons and equipment and other military supplies.

  The military industry is the core of the country's manufacturing industry, representing the country's advanced technological capabilities and equipment manufacturing capabilities. The development of the military industry has greatly driven the progress of the country's science and technology and industry. Taking the United States as an example, 90% of the technology in the US aviation industry comes from the technology transfer of military aircraft. Information technology, marked by computers and the Internet, was originally developed for military purposes. Due to the strong market demand, it has caused a blowout development after being transferred to civilian use, which has promoted the transformation of the entire society.

  In the process of development, China's military industry has formed an industrial pattern of "small core, large cooperation, and integration of the army and the people". This industrial system highlights the main business, strengthens the foundation of military products, improves the utilization rate of resources, and forms an overall optimization.

  ◆Small core: The development and production capabilities of major projects such as system design, key technologies and system integration, as the main body of the development of the military high-tech enterprise group, form a "small core".

  ◆Large cooperation: General supporting and processing capabilities should be based on the layout of the whole society, and form a "grand cooperation" based on the foundation of the national economy.

   Integrating the army and the people: On the one hand, the non-system-level production enterprises in the original military industry system will gradually enter the capital market through the asset operation platform of the group company, and use the power of the capital market to further expand and become stronger; On the one hand, some private enterprises with technological advantages will gradually enter the ranks of supporting product suppliers.

   Mainly used in refrigeration and low temperature occasions: superconductivity, controlled thermonuclear reaction, launch vehicle cooling test, missile launch system cooling, low temperature radiation test of reactor materials, recovery of reactor fission gas by cryogenic adsorption and liquefaction distillation, deuterium Cryogenic distillation extraction, etc.

  The purpose of ship refrigeration is to realize the refrigerated transportation of goods and provide cold source for ship air conditioning.

  On ships, refrigeration technology is widely used in refrigerated cargo transportation, food refrigeration, fish preservation, natural gas liquefaction and storage and transportation, refrigerated container "cold chain" transportation, and air conditioning in ship cabins. Ship refrigeration includes offshore fishing vessels, commercial refrigerated vessels, refrigerated cargo holds of marine transport vessels and cold storage for ship meals. In addition, there are refrigeration of marine engineering ships and storage and transportation of liquefied natural gas.

  Fisheries refrigerated vessels usually form a fleet with offshore fishing vessels. Onboard refrigeration units cool, freeze, process and store the catch for the vessel and other vessels in the fleet. As a link in the food cold chain, commercial refrigerated ships complete the transfer of various aquatic products or other refrigerated foods and ensure the necessary transportation conditions for food during transportation. The refrigerated cargo hold on the transport ship is mainly responsible for the storage and transportation of imported and exported food. The ship's food cold storage provides all kinds of refrigerated food for the crew to meet the must-haves of the crew's life during the ship's voyage. In addition, various types of ship refrigeration units also provide the crew with the cold drinks and food they need to live on board. In order to ensure the combat effectiveness of ships and adapt to long-term concealed diving, ammunition storage, etc., refrigeration technology is also widely used.
