Product Description

Introducing the NECH Series: Revolutionary Evaporative Condenser and Closed Cooling Tower
Product Model: NECH The NECH model stands out as a prominent type of evaporative condenser, renowned for its innovative mixed flow heat transfer system, characterized by a vertical cross-flow direction of both air and refrigerant steam. This pioneering design ensures that air moves seamlessly and uniformly through the condenser, greatly enhancing heat exchange efficiency and optimizing overall performance.

Advantages

 

· Revolutionary mixed flow heat transfer mechanism for superior condensation efficiency.
The ingenious vertical cross flow direction of air and refrigerant steam ensures uniform air distribution through the condenser, optimizing efficient heat transfer.

· Advanced secondary heat transfer system for unmatched cooling efficiency.

The spray water elegantly traverses the condenser coil, engaging in an initial heat exchange, then gracefully proceeds through the lower PVC heat exchange layer for a secondary phase, culminating in its journey by collecting in the water basin for recycling. This comprehensive process significantly boosts cooling efficiency.

· Innovative closed circuit system offering energy savings and eco-friendliness.

With the refrigerant condensing in a closed circulation within the coil, this design maintains cleanliness, reduces water consumption and maintenance costs, and ensures extended service life of the equipment.

· Ingeniously compact structure design that combines high strength with convenience.

Featuring a minimal footprint, this design simplifies shipment processes and offers ease of installation and maintenance.

 

Work Principle

When the NECH evaporative condenser is in operation, a symphony of engineering excellence unfolds:
The condensing coil serves as the primary pathway for refrigerant steam, a crucial component that efficiently transforms refrigerant steam into a liquid state, leveraging the power of evaporation to absorb heat, facilitated by the continuous shower of cooling water. This cooling water cascades elegantly around the coil unit before it continues its journey into the advanced PVC heat exchange system, where it continues to conduct a secondary, highly effective heat transfer process. Concurrently, the powerful axial flow fan injects energy into the system, inducing a cross flow of air within the condenser to engage in an elaborate heat exchange with the refrigerant steam, culminating in superior condensation efficiency and performance.

Instructions for Selection
1. Begin by confirming both the condensing temperature and the wet bulb temperature. This establishes the foundational parameters for optimal selection.
2. Accurately calculate the total heat abstraction amount that flows through your system to the condensers. This is crucial for efficiency.
3. Refer to the detailed values in Table 2 or Table 3 to select an appropriate heat abstraction amount correction index. This ensures tailored performance.
4. Multiply the total heat abstraction amount by the chosen heat correction index. This calculation provides the condensing load under specific working conditions.
5. Consult the Graph Specification sheet to select the heat abstraction amount data that meets or exceeds the corrected data. This guarantees robust operation.
