Absorption Chiller - EJ 40A TRU Specifications

General Information:

• Model: EJ 40A TRU
• Serial No.: CH-01
• Year of Manufacture: 2018
• Cooling Capacity: 1407 kW (approx. 400 tons of cooling)
• Power Supply: 380V, 50Hz (standard voltage and frequency for industrial applications)

Performance:

• Cooling Capacity:
  • 1407 kW or 400 tons of cooling.
  • This is the chiller's maximum cooling output under standard operating conditions (often rated at a chilled water temperature of 7°C and hot water temperature of 85°C, depending on the specific setup).
• COP (Coefficient of Performance):
  • COP typically ranges from 1.0 to 1.2 for absorption chillers, meaning for every unit of heat input, the chiller can produce approximately 1-1.2 units of cooling power.

Operating Parameters:

• Cooling Water Inlet Temperature: Typically 12-20°C (depending on the application and climate).
• Chilled Water Temperature Range: Generally, the chilled water temperature can range from 5°C to 15°C.
• Hot Water Inlet Temperature: Typically around 80-90°C (from a hot water source such as waste heat, steam, or a thermal oil system).

Power Consumption:

• Power Supply: 380V, 50Hz, which is standard for many industrial absorption chillers.
• Electrical Power Consumption:
  • Absorption chillers generally require little electrical power compared to vapor compression chillers since they are driven by heat energy rather than electric compressors.
  • Power consumption is mainly for the pump and auxiliary equipment (e.g., fans, controllers). The exact power consumption will depend on the operating conditions.

Physical Dimensions and Weight:

• Dimensions: Varies depending on the configuration and specific installation needs, but typically large (several meters in length and height) to accommodate the absorption system and related components.
  • For a unit of this capacity, dimensions can be roughly around 3-5 meters in height, 5-7 meters in length, and 2-3 meters in width.
• Weight: The unit is likely to weigh in the range of 8-12 tons (depending on design).

Heat Source Requirements:

• Hot Water / Heat Source: Absorption chillers use a heat source, such as steam, hot water, or hot gas, to drive the refrigeration cycle.
  • Typically, steam or thermal oil can be used to generate the necessary heat.
  • The heat exchanger is an essential component in transferring heat from the hot fluid to the working fluid in the chiller.

Efficiency & Environmental Impact:

• Environmentally Friendly: Absorption chillers are considered more environmentally friendly compared to traditional electric chillers because they can use waste heat or renewable energy sources to generate cooling.
• Efficiency: Absorption chillers usually have an efficiency rating (COP) of around 1.0 to 1.2, depending on the heat source and operational conditions.

Control and Automation:

• Automation and Controls:
  • Includes microprocessor-based controllers for optimizing system performance, controlling the inlet/outlet temperatures, pressure, and energy consumption.
  • Some models may have advanced control features, including remote monitoring, automatic load adjustment, and integration with building management systems (BMS).
