Imagine a facility generating its own electricity, capturing waste heat for process steam, and powering air conditioningall from burning fuel just once.This is CCHP technology , quietly transforming India's industrial energy management.

⚡ Understanding CCHP: The Ultimate Energy Multitasker

CCHP(Combined Cooling, Heating, and Power), also called trigeneration, produces three valuable outputs from a single fuel input:

  • ⚡ Electricity – via gas engines, turbines, or fuel cells
  • 🔥 Heating – hot water or steam for processes or space heating
  • ❄️ Cooling – chilled water via absorption chillers using waste heat

While conventional power plants waste 60 - 70 % of fuel as heat, CCHP captures thermal energy achieving overall efficiencies of 75 - 85 % vs 30-45% for separate systems.

How CCHP Systems Work: The Energy Flow

Step 1: Primary Power Generation

Prime movers(gas engines, turbines, or diesel generators) burn fuel to produce mechanical energy, driving electricity generation.

  • Efficiency: 30 - 40 % (similar to grid power plants)

Step 2: Heat Recovery for Process Heating

Exhaust gases(400 - 550°C) and engine cooling circuits(80 - 95°C) are captured via heat recovery systems:

  • Exhaust heat exchangers → steam(up to 180°C)
  • Engine jacket cooling → hot water(80 - 95°C)
  • Heat recovery: 40 - 50 % of fuel energy

Applications:

  • Industrial processes(sterilization, cleaning)
  • Space heating
  • Domestic hot water
  • Boiler feedwater preheating

Step 3: Absorption Cooling from Waste Heat ❄️

Remaining thermal energy powers vapour absorption chillers like BROAD’s exhaust - fired VAM systems:

  • ✓ COP: 0.7 - 1.3
  • ✓ Cooling capacity: 0.35 - 0.45 TR per kW of prime mover capacity
  • ✓ Zero additional fuel consumption

Cooling applications:

  • Process cooling(pharma, food processing)
  • Air conditioning(offices, hospitals, data centers)
  • Industrial operations(plastics molding, metalworking)

CCHP vs.Conventional Systems: The Efficiency Revolution

> Conventional Approach

  • Electricity: Grid power 30 - 35 % efficient
  • Heating: Boilers 75 - 85 % efficient
  • Cooling: Electric chillers COP 3 - 6
  • Combined efficiency: 45 - 50 %, massive fuel waste

> CCHP Approach

  • Electricity: 30 - 40 % of fuel energy
  • Heating: 40 - 50 % of fuel energy
  • Cooling: 5 - 15 % of fuel energy(from waste heat)
  • Combined efficiency: 75 - 85 %, minimal waste

Result: 30 - 50 % reduction in primary energy consumption .
