Seeking advice on the reason for the low outlet temperature of the regenerator in lithium bromide refrigerators

In the morning, it was found that the temperature at the outlet of the regenerator was low; it should normally be around 80-90°C, but in the morning it was in the high 40s°C. After inspection, the manufacturer suspected that hot water was not circulating in the regenerator. No blockage was found after disassembling the heat exchanger. I don’t know what the reason is. Please help analyze the reason
Hot water flows through the tube side of the regenerator, while lithium bromide solution flows through the shell side. Under normal conditions, the hot water inlet is around 100°C, while the outlet temperature is in the high 80s.
The hydrophobicity is fine; then check whether the flow rate of the solution pump is normal. It’s also possible that there is a leakage between the high-temperature and low-temperature exchangers
Holes, abnormal vacuum levels, insufficient hot water flow – all of these can be suspected as potential issues. The simplest approach is to check whether the refrigerant level has increased and whether there are any changes in its concentration. The above information is provided for reference only
