In a 3-pipe gas defrost system, where is the defrost condensate liquid returned to?

In a 3-pipe gas defrost system, the defrost condensate liquid is returned to the Low Temperature Refrigeration System (LTRS). This design allows for the efficient handling of the condensate generated during the defrost cycle. By directing the condensate back to the LTRS, the system can utilize this liquid in the refrigeration cycle, thereby enhancing its overall efficiency.

Returning the defrost condensate to the LTRS aids in maintaining the proper temperature and pressure conditions necessary for the refrigeration process. Moreover, it helps in managing the moisture that accumulates during defrosting, which is vital in preventing potential operational issues like ice buildup or system inefficiencies.

The choice to return to the LTRS rather than other system components, such as the High-Pressure Receiver (HPR), Intercooler, or Low Temperature Re-circulated Liquid (LTRL), is based on the need for effective temperature management in the refrigeration system during the defrost cycle. This ensures that the system continues to operate smoothly while optimizing resource use.
