What is the current maturity level of lithium bromide heat pump energy-saving technology in China? Seek successful examples of using heat from 95-degree condensate water for recovery. Recently, I was working on a plan to improve the energy efficiency of a system that uses condensed steam as a heat source. On average, 5 cubic meters of condensate at 95 degrees Celsius are generated per hour, and this liquid needs to be cooled to below 40 degrees Celsius for use in industrial water supply purposes. Several solutions were considered: 1. Using a cooling tower – this approach is not cost-effective, as it results in waste of thermal energy. 2. Using air-cooled or finned heat exchangers – this involves high costs, increased maintenance requirements for fans and pumps, and again, thermal energy is wasted; however, it is a viable option. 3. Using a heat pump cycle with lithium bromide, where the recovered thermal energy is used to generate hot water, while the cooled condensate is used for industrial water supply. In fact, there are very few successful cases of such systems in use in China at present, and there is no reliable data available regarding investment costs, operational costs, or the economic viability of these systems. Using the mature product lines available from foreign companies comes at an extremely high cost, which is unaffordable. Dear experts, if you have any successful examples, please share your knowledge with us.
I am the client; I am currently conducting a feasibility study on the technical solution. Once the feasibility is approved by my boss, it will be necessary to find companies responsible for design and installation to carry out the work. If any experts have proven solutions, I would appreciate it if you could share them.
In summary, the following 3 points should be taken into consideration: 1. The design technology and processes are highly mature, with numerous practical applications; we should avoid those solutions that are still under verification, as we don’t want to serve as test subjects； 2. Economical maintenance and repair costs ； 3. Operating costs such as electricity fees are low; investment depreciation costs are considered last, allowing for a larger initial investment.
Amateurs watch the excitement, while experts focus on the details. Although there are many listed companies, there are very few applications of lithium bromide heat pump technology. Or could you recommend a few? Thank you.
I’m busy on a business trip for inspections; I’ll get in touch with you later.
