Lithium bromide absorption chiller
Thread Content
What are the temperature and pressure requirements for the inlet water in lithium bromide absorption chillers? Can steam condensate with a relatively high temperature be used with lithium bromide absorption chillers? ? ? How can it be done in practice? Could anyone give some advice! ! !
I can tell the original poster with certainty that, as a heat source, lithium bromide can generally work at temperatures up to 200°C; steam condensate is a suitable choice for use as a heat source. As for pressure, it is determined by temperature – pressure remains constant in this case. This technology is quite mature, and many manufacturers are involved in its development; one can approach these manufacturers for technical discussions. I have just completed a feasibility study on this topic recently
It should be possible; you should make a request to the manufacturer to see if they can meet the requirements. The current trend is to recycle low-temperature heat sources.
As long as you have a need for cold treatment, you can do this; we’re here to support you, no problem – just get in touch with the manufacturer!
To give a practical example, my company has four bromine dyeing units; two of them use 98-degree hot water, one uses 8 kilograms of steam, and another uses 130-degree hot water. So, there are many possible heat sources, with temperatures and pressures that can be adjusted. Different heat sources result in different structures within the units as well.:lol
It should be low-grade thermal energy or waste heat, not just low-temperature thermal energy
The so-called difference in structure refers to variations in the areas where high and low levels of heat generation occur, as well as in the areas used for waste heat utilization; since the temperature difference is small when using hot water, the required area is larger
What is all the cold energy generated by everyone used for? ? ?
Energy for lithium bromide chiller: Steam: usually 8, 6, 4 kilograms of steam or some value in between. Only Yantai Eiyo has this model for low-pressure steam. Direct combustion: Natural gas, gas, liquefied petroleum gas, oils, etc. Hot water: Temperature ranges from 140 degrees to 85 degrees. Regarding the 200-degree hot water mentioned, since the lithium bromide solution causes increased corrosion of the unit at 185 degrees, the temperature should also not exceed this value. Additionally, the high-temperature generator of the standard unit is made of copper tubes. If the temperature is above 140 degrees, it is necessary to consider replacing the copper pipes with stainless steel pipes, as stainless steel 316 can withstand high temperatures. 304 may not meet the requirements.
