Nobel Park business center in Tyumen: absorption chiller on gas engine waste heat

In brief. At the Nobel Park business center in Tyumen, cooling for air conditioning comes from a Thermax absorption chiller running on gas engine waste heat, 12/7 °C water. We supplied the machine and carried out commissioning.

At the Nobel Park business center in Tyumen, cooling for air conditioning comes from a Thermax lithium bromide absorption chiller running on hot water from the waste heat of gas engine generator sets. The water is cooled from 12 to 7 °C. We supplied the equipment and carried out commissioning.

What was the task?

The sources do not describe the task; the engineering logic is as follows. A 15-story building needs cooling in summer, and the gas engine heat is free in those months. The machine turns it into cooling, and electric chillers do not add to the electrical load.

How does the scheme work?

The classic: gas engines and a hot water absorption chiller

The gas engines give their waste heat to hot water. It drives the absorption chiller, which cools the water for air conditioning to 7 °C.

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.
