Engineering Requirement

Chilling Plant requires an effective air-cooling system and for that Dry Expansion (DX) type of shell and tube heat exchanger plays a pivotal role. Our experienced equipment engineering services team was commissioned to validate the dry expansion heat exchanger thermal design, conduct thermal rating assessments, and optimize both internal design and volume considerations for the heat exchanger. Their objective was to ensure optimal heat exchange between refrigerant R134a and Saturated Air, fostering efficient air cooling while minimizing energy consumption.

Harnessing the capabilities of AspenTech’s Exchanger Design & Rating (EDR)™, Rishabh Pro Engineering worked on dry expansion evaporator thermal design.

The DX-Type Shell and Tube Heat Exchanger:
Characterized by its NEU TEMA-type configuration, the DX-type Shell and Tube Heat Exchanger was the cornerstone for facilitating dry-type evaporator thermal design between refrigerant R134a and Saturated Air within the Chilling Plant. The primary aim was to achieve superior heat transfer efficiency while minimizing energy consumption, thereby optimizing operational costs.
