lithium bromide absorption refrigerator uses lithium bromide solution as absorbent and water as refrigerant, and uses water to evaporate and absorb heat under high vacuum to achieve the purpose of refrigeration. So what are the advantages and disadvantages of lithium bromide absorption refrigerator? Let's briefly introduce the advantages and disadvantages of lithium bromide absorption refrigerator

· Advantages of lithium bromide absorption chiller

1. It takes heat energy as power, consumes less electric energy, and has low requirements for heat source. It can use all kinds of low potential heat energy, waste steam and waste heat, such as saturated steam with gauge pressure higher than 20KPa (0.2kgf/cm2), hot water with high dry temperature of 75 ℃, geothermal energy and solar energy, which is conducive to the comprehensive utilization of heat sources. It has good power saving and energy-saving effect and good economy

2. The whole unit has no other moving parts except the shielded pump with very small power, which has low vibration, low noise and quiet operation

3. With lithium bromide solution as the working medium, the machine operates in a vacuum state, which is odorless, non-toxic, explosion-free, safe, reliable, pollution-free, and conducive to meeting the requirements of environmental protection

4. Wide adjustment range of cooling capacity. With the change of external load, the unit can carry out stepless adjustment of cooling capacity within the range of 10% - 100%. Even under low load operation, the thermal efficiency hardly decreases, the performance is stable, and it can well adapt to the requirements of load changes

5. Strong adaptability to changes in external conditions. For example, the standard external conditions are: steam pressure 5.88 x 105Pa (6kgf/cm2) gauge pressure, cooling water inlet temperature 32 ℃, and refrigerant water outlet temperature 10 ℃. The actual operation shows that it can operate stably within the wide range of steam pressure (1.96 ~ 7.84) x 105Pa (2.0 ~ 8.0kgf/cm2), cooling water inlet temperature 25 ~ 40 ℃, and refrigerant water outlet temperature 5 ~ 15C

6. Easy installation and low requirements for installation foundation. The vibration of the machine is small during operation, so there is no need for special foundation, and only static load can be considered. 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 steam, water and electricity as required

7. Simple manufacture, convenient operation and maintenance. In addition to shielding pump, vacuum pump, true space and other auxiliary equipment, almost all of the units are heat exchange equipment, which is relatively easy to manufacture. Since the unit has stable performance and strong adaptability to changes in external conditions, the operation is relatively simple. The maintenance of the unit is mainly to maintain its air tightness

· Disadvantages of lithium bromide absorption refrigerator

1. In the presence of air, lithium bromide solution has strong corrosivity to ordinary carbon steel. This not only affects the service life of the unit, but also affects the performance and normal operation of the unit

2. The unit operates under vacuum. Air is easy to leak in. Even if a small amount of air is leaked, the performance of the unit will be seriously damaged. Therefore, the refrigerator requires strict sealing, which adds difficulties to the manufacture and use of the machine

3. The heat removal load of the unit is large, because the condensation and absorption process of refrigerant steam are heat removal processes. In addition, the requirements for the quality of cooling water are also relatively high. In places with poor water quality, special water quality treatment should be carried out during use, otherwise the normal performance of the unit will be affected
