Tri-generation or Combined Cooling, Heat and Power (CCHP) refers to the generation of electrical power, chilled water and hot water. Introducing an absorption chiller to the system allows the production of both cold and hot water to the power generation process which can be utilized in a building’s HVAC system or utilized in a manufacturing plant.
An absorption chiller is basically a refrigerator that uses a heat source in order to provide the energy needed to drive the cooling system. Nowadays, these chillers are rapidly replacing regular compressor refrigerators where electricity is unreliable or expensive; plus, noise from the compressor also contributes to noise pollution.
In comparison with conventional refrigerants, absorption based refrigeration technology offers the most established solution for reducing enviromental emission from air conditioning systems:-
- Utilizes relatively inexpensive waste heat recovered from cogen plant.
- Cost of production of chilled water substantially reduced.
- Maintenance cost low compared to conventional chiller.
- Noiseless operations.
- Low operating costs and lifecycle costs.
- Using water as a refrigerant replaces the use of ozone damaging substances.
