Vyborzhets agricultural complex: two hot water absorption chillers, 3.8 MW
In brief. At the Vyborzhets mushroom agricultural complex, two Thermax 5G 6LH absorption chillers with a total capacity of 3.8 MW run on waste hot water. Heat is rejected by two NCT VR4 cooling towers.
The Vyborzhets mushroom complex in Vsevolozhsk gets its cooling from two Thermax 5G 6LH lithium bromide absorption chillers with a total capacity of 3.8 MW. They run on waste hot water, and heat is rejected by two NCT VR4 cooling towers. We carried out the design of the cooling system, supply, installation supervision and commissioning. The machines were delivered in 2018.

| City | Vsevolozhsk, Leningrad Region |
| Generation | 4 GE Jenbacher gas engines, 3 MWM TCG 2032V16 gas engines, a hot water boiler for CO2 production |
| Heat | Waste hot water |
| Absorption chiller | 2 × Thermax 5G 6LH, 1.9 MW each, 12/6 °C water |
| Heat rejection | 2 NCT VR4 evaporative cooling towers |
| What the cooling is for | Air conditioning in the warm season |
| Our work | Cooling system design, supply, installation supervision, commissioning |
What was the task?
Cooling is needed for air conditioning in the warm season. The engineering logic is as follows: an energy center with seven gas engines and a boiler produces electricity and heat; in summer the heat is free, and it can be put to work making cooling instead of compressor chillers.
How does the scheme work?
Two heat sources: gas engines and a boiler house
The energy center has both engines and a boiler, and the machines run on waste hot water. The diagram shows the general case with two sources.
What was the result?
The complex got 3.8 MW of cooling from waste heat. The materials contain no further figures on the effect.
