A refrigerant exchanges heat with an open recirculating cooling water loop inside of the HVAC machine. The cooling water loop then releases the waste heat to the atmosphere in a cooling tower. This last exchange occurs in a second heat exchanger called the condenser. Normally these heat exchangers are both shell and tube units. Water on the tube side, refrigerant on the shell side.
Read MoreThere is a common misconception that closed cooling and heating systems require less maintenances and service attention when compared to other open cooling systems. This common misconception is based on the fact that closed systems operate routinely and the water is not visible. This is completely untrue.
Closed HVAC systems operate as the primary contact point for air in climate control systems, and they provide direct cooling of data processing equipment and process machinery. If proper water treatment programs and maintenance servicing is not carried out, the consequences could be catastrophic. These problems can sometimes occur quickly without much warning.
The operating efficiency of Open recirculating cooling water loop systems depends upon keeping the two heat exchangers clean and corrosion-free. Chemenergy places this as a major goal when preparing water treatment solutions for open recirculating cooling water loops. Protecting the system's piping is also essential to running an efficient system.
Chemenergy will prevent the following from occurring in an open recirculating cooling water loop:
- Loss of water quality & Purity
- Loss of flow- Water losses
- Dissolved oxygen
- Microbiological problems / contamination
- Tube and shell heat exchanger corrosion
- Tube and shell degradation and reduction of lifetime
- Protection of water from loop to cooling tower
Chemenergy can offer prevention programs of operating and water-realted problems that can occur in your open recirculating cooling water loop system. Without the proper care and servicing, open recirculating cooling water loops will experience performance and operational problems resulting in shut-downs, increased production downtime, asset destruction, and loop lifetime reductions.
