Comparison to Other Systems

In comparison to other cooling systems, the MTN Fresnel Solar 330 kW Cooling System stands out for its utilization of a double effect absorption cooling system, which allows for higher temperature heat input and increased water production. This unique feature sets it apart from conventional cooling systems that rely on single effect absorption or other technologies.

By using mirrors to focus sunlight onto a central absorber tube, the system is able to generate water at 180 degrees, which is then transferred to a chiller for cooling. This method not only improves efficiency but also reduces energy consumption.

However, it is important to note that the MTN system also requires backup units in the form of electric chillers, indicating that there may be limitations to relying solely on solar energy for cooling.

Nonetheless, the use of concentrated solar energy and the implementation of a double effect absorption cooling system demonstrate the system’s advantages in terms of efficiency and increased water production.

Storage and Backup

Storage and backup systems play a crucial role in ensuring continuous cooling operation and energy efficiency in solar cooling installations. Integration methods, such as the use of tanks for storing chill water, provide a backup solution in case of system downtime. These storage tanks allow for energy storage during maintenance or other issues, helping to save energy and maintain a consistent cooling process.

Additionally, the heat recovery system collects the heat generated by the concentrated solar power (CSP) system and transfers it to the chiller, further enhancing energy savings. Safety mechanisms, including pressure switches and transducers, are in place to ensure the smooth operation of the storage and backup systems.

The recirculation system acts as a backup measure to ensure continuous cooling even if the generated water falls below the set point, contributing to the overall efficiency and effectiveness of the solar cooling system.

Overall, the integration of storage and backup systems in solar cooling installations enhances energy efficiency and ensures uninterrupted cooling operation.
