Description

The MTU 12V4000 L33 gas genset is a complete CHP system for simultaneous production of electricity and heat. Designed for continuous grid-parallel operation, it serves as a primary energy source and is already configured for integration with an absorption chiller for trigeneration (Power + Heat + Cooling).

ABSORPTION CHILLER UNIT

Carrier 16LJ-F41 – Single Effect Hot Water Absorption Chiller

The absorption chiller uses recovered heat from the CHP (engine cooling water and exhaust heat) to produce chilled water without mechanical compression.

Cooling Capacity

• Nominal Cooling Capacity: 1,178 kW

Chilled Water Circuit

• Flow rate: 56.4 L/s
• Pressure drop: 45 kPa
• Connection: 8” DIN
• Retention volume: 0.48 m³

Cooling Water Circuit

• Flow rate: 93.1 L/s
• Pressure drop: 117 kPa
• Connection: 10” DIN
• Retention volume: 1.39 m³

Electrical Supply

• 400 V – 3 phase – 50 Hz
• Electrical absorption: 12.8 A

Installed Pumps

• Absorbent pump No.1: 3.0 kW
• Absorbent pump No.2: 0.4 kW
• Refrigerant pump: 0.4 kW
• Purge pump: 0.4 kW
• PD cell heater: 0.038 kW

Physical Data

• Dimensions (L x H x W): 5,330 x 3,080 x 1,690 mm
• Weight: 13,700 kg

Description

The Carrier 16LJ-F41 absorption chiller operates using a lithium bromide–water absorption cycle. Unlike compression chillers, cooling is produced using thermal energy recovered from the cogenerator, with minimal electrical consumption. The system converts waste heat into chilled water, completing the trigeneration process and significantly increasing overall plant efficiency.
