Tau Galereya shopping mall: two 2,200 kW Thermax absorption chillers
In brief. At the Tau Galereya shopping mall in Saratov, two 2,200 kW Thermax 5G 6L C absorption chillers run on hot water from gas engines. The company's materials estimate the benefit at more than RUB 7 million per year.
At the Tau Galereya shopping and entertainment mall in Saratov, two 2,200 kW Thermax 5G 6L C lithium bromide absorption chillers make cooling from the heat of gas engine generator sets. The contract was signed in April 2014, and the equipment was delivered in November of the same year. We supplied the chillers and carried out installation supervision and commissioning.

What was the task?
The engineering logic is this: a shopping mall needs air conditioning in summer, and a 4,400 kW compressor chiller is a significant electrical load. At that time the gas engine heat is not needed for heating, so it is used to make cooling.
How does the scheme work?
The classic: gas engines and hot water absorption chillers
Two chillers take hot water from the engines and make water at 12/7 °C. The rooftop heat rejection equipment removes the chillers' heat. Without absorption chillers, the same heat would be dumped into the atmosphere in summer.
What was the result?
The company's materials estimate the annual benefit from using waste gas engine heat in summer at more than RUB 7 million. The calculation method was not given in open materials, so this is a guide, not a guarantee for your site.
