In addition to commonly recognized built-in heat pump systems, we engineer and convert your chilled water system into a hot water producing heat pump system for the winter operation. This requires a sea or lake as heatsink/source. The efficiency of such a system could be up to 6 (kW heating/kW electricity). This system considerably reduces the use of conventional fuel-fired boiler system.

Our engineering optimization is not limited to chilled water systems. We also engineer;
⦁ Free cooling possibilities on both water and airside
– Waterside: utilization of cooling tower when climate conditions appropriate
– Airside: utilization of outdoor air when enthalpy conditions of outdoor air appropriate
⦁ Gas turbine inlet air cooling to increase the capacity and the efficiency of a gas turbine.
– Chilling down (and also keeping the water content at an optimal level of) the inlet air to the gas turbines alter the capacity and efficiency of gas turbines considerably (5 to 10%).
– We engineer the optimal inlet air conditioning parameters that could be achieved by a custom-designed air conditioning system based on the climatic conditions of your power plant site.
– We design and implement this air conditioning system which would consist of chillers(absorption chillers if the recovered steam from hot gas flue is available for such use, or electric-driven chillers -air cooled-water cooled), special coils, water injection systems, filtration systems integrated onto the air inlet side of the gas turbines.

⦁ There is a considerable chiller inventory in the market, operating with phasing or phased out refrigerants, yet in good operating conditions. The chances are good that these chillers might be retrofitted to operate with new refrigerants. We do this engineering for you.
⦁ We choose the optimal retrofit alternative which will yield the best possible efficiency level with the least investment. While retrofitting, we will thoroughly diagnose your chiller and make sure that it will function like a new one by applying other necessary corrective actions.

⦁ We thoroughly analyze your chilled water system (production system/distribution system/users (AHU-FCU-process)) and come up with a feasibility report based on proposed system optimization and close to actual demand scheme with engineering calculations. This will provide you with a reliable decision base for such investment.
⦁ Optimization includes the following:
⦁ Central chilled water production with properly sized and positioned decoupling
⦁ Optimization of system zones, application of possible improvements such as variable flow in parallel with variable demand.
⦁ Free cooling applications (mostly possible for process cooling): for processes that require both usual temperature chilled water (btw 5-14 C) and moderate temperature chilled water (btw 15-22 C), cooling demand for moderate temperature chilled water could be satisfied by means of cooling towers. We carefully analyze this possibility for you by taking your production demands throughout the year, wet bulb/cooling tower outlet temperature scheme.
⦁ We provide you with a feasibility analysis along with a scheme design for a possible&feasible investment.
