Natural History Museum, London, UK

In brief. Two 705 kW Thermax chillers running on hot water from Jenbacher engines provide cooling for the Natural History Museum in London.

The Natural History Museum in London gets its cooling from two 705 kW Thermax absorption chillers. They run on hot water from Jenbacher gas engine generator sets, which also supply the museum with electricity.

Why is this example useful for a Russian site?

The source gives no figures on the effect, so the example shows the layout: two identical chillers instead of one, so if one stops, half the cooling remains. In a Russian historic building, the main issue is often getting the equipment inside: at the Central Customs Administration in Moscow, the chillers were delivered in sections and assembled in the basement. More: trigeneration for business centers and hotels.

How does this kind of scheme work?

Hot water from the Jenbacher engines drives the chillers.

The engine jacket and exhaust heat exchanger heat water to about 90 °C. The water goes through a heat exchanger into a single-effect Thermax chiller with a COP of about 0.8. The chiller supplies 7/12 °C water to the consumer and rejects heat to an NCT cooling tower. Surplus heat is removed by dump radiators.
