Omega Tower Business Center: Absorption Chiller on Heat from Two Bosch Gas Engines

In Minsk, the Omega Tower business center, the neighboring shopping mall and a fitness club get their cooling from one 500 kW Thermax LT 18C lithium bromide absorption chiller. It runs on hot water from two Bosch gas engine generator sets, and heat rejection is provided by an NCT cooling tower. The contract was signed in December 2016.

What was the task?

Three buildings take cooling from one chiller plant. The engineering logic is this: the engines produce electricity and heat, and in summer this heat becomes cooling for all three buildings. The news item about the contract puts equipment localization, prices and schedules first.

How does the scheme work?

The classic: gas engine and hot-water absorption chiller

Hot water from the two engines goes to one LT 18C machine. A single-effect machine of this series gives a COP of 0.65–0.72: 500 kW of cooling needs about 700–770 kW of heat. The NCT cooling tower removes the machine's heat.

What was the result?

The contract was signed in December 2016 after more than a year of work on the project. The materials give no figures on the effect.
