(Deep) Cooling
The advantage of the high exhaust gas temperature is also evident when coupling with an absorption refrigeration system: hot water temperatures of 80-90°C are required for this. The advantage of coupling an absorption chiller is the increase of the annual operating hours of the CHP unit. Thus, the microturbine can be operated in summer as well as in winter with high utilization rates. Such a plant is thus suitable for the base load supply of buildings with a constant demand for electricity, heating and cooling.
The microturbine thus offers the possibility of ensuring the total energy supply of a building by simply coupling an absorption chiller. Such an installation achieves efficiencies of up to 85% and is particularly suitable in:
- commercial high-rise buildings
- larger supermarkets
- hospitals
- banks
- event halls
- commercial units
Cogeneration is based on the simultaneous generation of mechanical energy, which is usually converted directly into electricity, and heat, which can be used directly for refrigeration using sorption technology.
Absorption refrigeration systems are based on a technology introduced by Albert Einstein in 1926. It uses a refrigeration cycle in which the changes of state of the refrigerant water and the absorber lithium bromide reach the temperature parameters of conventional chillers.
Century absorption chillers
Century absorption chillers are LiBr units capable of producing refrigeration down to 6°C and are well suited for use in conjunction with microturbines.
Whether used individually or in conjunction with a Capstone microturbine, Century absorption chillers feature:
- a tremendous service life of 30 years,
- tremendous efficiency - 2,000kW cooling with less than 10kW electric,
- easy handling
- few and easily accessible wearing parts - the units are therefore very low maintenance
- 100% ozone friendly, CFC free
- low noise and low vibration
Hot water driven, steam driven or gas fired - the units are available in power ranges from 35 kW to 5,275 kW and you can choose between a standard product or an individually designed unit.
