The production and application of lithium bromide refrigerator are developing day by day, and its design scheme is becoming more and more perfect. In recent years, it is widely used in China's industry. However, the design of extraction system and internal thermal insulation layer of most lithium bromide refrigerators in China is not ideal. This paper puts forward some suggestions for improvement, Punoke vacuum technology suggests the application of vacuum system in lithium bromide refrigerator to ensure the normal operation of the refrigerator.

Lithium bromide refrigerator is an environment-friendly refrigerator, which has no destructive effect on the atmospheric ozone layer. In addition, it needs to use punook vacuum system in the process of manufacturing, commissioning and operation. As for why it is selected, let's follow the editor to understand the characteristics of punook vacuum system in lithium bromide refrigerator.

First of all, we must understand what is lithium bromide refrigerator. Lithium bromide refrigerator, namely lithium bromide absorption refrigerator, uses lithium bromide aqueous solution as working medium, in which water is refrigerant and lithium bromide is absorbent. Lithium bromide is a salt, white crystal, easily soluble in water and alcohol, non-toxic, stable chemical properties and will not deteriorate. When there is air in lithium bromide aqueous solution, it has strong corrosivity to steel. Lithium bromide absorption refrigerator can only be used for air conditioning equipment and cold water preparation in production process because water is refrigerant and evaporation temperature is above 0 ℃. This refrigerator can use low-pressure steam or hot water above 75 ℃ as heat source, so it plays an important role in the utilization of waste gas, waste heat, solar energy and low-temperature potential heat energy.

Advantages of vacuum system in lithium bromide refrigerator

1. Easy installation and low requirements for installation foundation. Since the vibration during operation is very small, there is no need for a special base. It can be installed indoors, outdoors, on the ground floor, on the floor or on the roof. During installation, it is only necessary to make general leveling and connect air and water pipes and power supply.

2. Simple manufacture, convenient operation and maintenance. In addition to shielding pump, vacuum pump, vacuum valve and other auxiliary equipment, almost all of the units are heat exchange equipment, which is easy to manufacture. Because the vacuum pump system has stable performance and strong adaptability to the changes of external conditions, the operation is relatively simple. The maintenance of vacuum pump system is mainly to maintain the required air tightness.

3. With heat energy as power, it does not need to consume a lot of electric energy, and the requirement for heat energy is not high. It can use all kinds of low potential heat energy, waste gas and waste heat, which is conducive to the comprehensive utilization of heat source, so the operation cost is low. If all kinds of waste gas and waste heat are used for refrigeration, a large number of cold sources can be obtained without spending operation cost, which has good power-saving and energy-saving effect and high economy.

4. With lithium bromide solution as the working medium and the refrigerator running in vacuum, it is odorless, non-toxic, non explosive, safe and reliable. It is known as a pollution-free refrigeration equipment, which is conducive to meeting the requirements of environmental protection.
