SSIDD - 300

System Overview

The Canstar IDEC Cooling System is a two-stage hybrid cooling solution combining Indirect Evaporative Cooling (IEC) and Direct Evaporative Cooling (EAC) to achieve maximum cooling efficiency with minimal energy consumption.

1. Indirect Cooling Stage (IEC):

   • Warm ambient air passes through an indirect heat exchanger.

   • Heat is reduced without adding humidity, ensuring dry, cool air.

   • Typical result: From 36°C, 30% RH to approx. 22°C, 65% RH (refer to diagram).

2. Direct Cooling Stage (EAC):

   • The pre-cooled air then enters a direct evaporative cooling media.

   • Water evaporation further drops the air temperature.

   • Typical result: From 22°C to 19°C, 85% RH (refer to diagram).

Technical Performance

• Cooling Efficiency: 120%–135% W.B. efficiency

• Air Quality: Delivers 100% fresh air

• Humidity Control: Maintains acceptable humidity level for comfort without excessive moisture.

• Energy Usage: Significantly lower than conventional refrigeration-based air conditioning.

• Eco-Friendly: Utilizes water as a cooling medium, reducing carbon footprint.

Diagram Explanation

Step 1: Warm Air Intake

• Ambient air (36°C, 30% RH, 12.5g/kg) enters the IDEC system.

Step 2: Indirect Cooling

• Through IEC module:

  • Heat is rejected via water evaporation on the other side of the heat exchanger.

  • Air is cooled without moisture gain.

  • Output: Cool air at ~22°C, 65% RH, 12.5g/kg.

Step 3: Direct Cooling

• Through EAC media:

  • Water evaporates directly into the airflow.

  • Temperature drops further.

  • Output: Cooler air at ~19°C, 85% RH, 14.5g/kg.

Step 4: Exhaust

• Heated air from the evaporation process is exhausted outside.

Key Benefits

• Maximum Cooling: Combines two cooling principles for enhanced performance.

• Lower Operational Costs: Up to 70% energy savings compared to traditional HVAC.

• Improved Comfort: Cooler supply air than IEC alone.

• Better IAQ (Indoor Air Quality): 100% fresh air with dust and particle reduction.

• Eco-Conscious: Reduced CO � emissions and refrigerant usage.

Ideal Applications

• Industrial Facilities: Printing factories, welding workshops, spray coating areas.

• Commercial Spaces: Malls, supermarkets, theaters, multipurpose halls.

• Educational Institutions: Schools and classrooms with high CO � levels.

• Agricultural & Clean Environments: Seed propagation labs, data centers.

• Public & Utility Areas: Airports, bus terminals, sports complexes.
