Central Customs Administration: cooling in the basement of an old building
In brief. In a historic building in central Moscow, two 500 kW Thermax LT-14 C absorption chillers run on the heat of five Capstone C200 microturbines. The chillers were brought in parts and assembled in the basement. Part of the cooling goes to the server rooms.
In the historic building of the Central Customs Administration in Moscow, a chiller plant has been built on the heat of five Capstone C200 microturbines. Two Thermax LT-14 C lithium bromide absorption chillers of 500 kW each cool water for air conditioning, and part of the cooling goes to the server rooms. The chillers were delivered disassembled and assembled in the basement.

What was the task?
The building stands in the historic center, where there is not enough electrical capacity. Compressor chillers would have required even more electricity, so cooling for the building and the server rooms is made from the heat of a mini power plant on microturbines. It was commissioned around 2015.
How does the scheme work?
Microturbines and an absorption chiller
The microturbines produce electricity, and their heat goes into hot water through a heat recovery unit. The water, together with heat from the boiler house, drives the absorption chillers, which supply cooling to the building network.
What was difficult?
The basement of the old building, with its narrow passages, cannot take a whole chiller. Each absorption chiller was delivered disassembled, in two parts, and assembled on site: this required complex rigging and installation supervision.
What was the result?
The chiller plant was successfully started up. The general contractor's letter of 29 July 2015 confirms on-time delivery, rigging, installation supervision and commissioning.
