What is Trigeneration?
Trigeneration refers to the simultaneous production of power, heat, and cold. It is coupling of CHP unit and LiBr absorption unit that allows transformation of the heat from cogeneration into the cold through the absorption process.
Advantages of Trigeneration
1. Effective utilization of heat from the CHP unit, also in summer months.
2. Significant cut down of electric power consumption (reduced operation costs in comparison to the conventional compressor cooling).
3. Nonelectric source of cold doesn't load the electrical distribution mains, particularly during the peak-tariff period.
4. Absorption cooling is typical of very low noise, low service demands and high durability.
Application
Trigeneration units can be operated wherever heat is in excess, and where the produced cold can be used, for example, for air conditioning of production, office, and residential premises. The production of technological cold is possible too. Trigeneration is frequently used to produce heat in winter months and cold in summer. However, simultaneous production of all the three forms of energy at the same time is also possible.
Trigeneration Type A
1. Connection of the hot water LiBr absorption chiller and CHP unit, the exhaust heat exchanger is a part of the CHP unit.
2. All the CHP unit's thermal energy is utilized to heat the water.
3. Advantage: three-way electronically controlled valve allows continuous control of the heat output intended for heating or cooling.
4. Suitable for the facilities that require heating in winter and cooling in summer.
Trigeneration Type B
1. Connection of the direct fired LiBr absorption chiller and CHP unit, the exhaust heat exchanger is a part of the absorption unit.
2. Hot water from the CHP unit's engine circuit is used for heating only.
3. Advantage: the efficiency of absorption cooling is higher owing to the higher temperature of exhaust gases.
4. Suitable for the facilities with the all-year parallel consumption of heat and cold.
