Chiller DAIKIN 55.3 kW chiller for biomethane cooling

Biogas Energy—Ternopil and its energy model

Biogas Energy—Ternopil is developing the renewable energy sector by converting organic raw materials into biogas, which is then processed into biomethane with controlled storage and transport parameters.

— Processing of up to 18,000–25,000 tonnes of organic raw materials per year, yielding gas of consistent quality;
— Fermentation cycles lasting 18–28 days with temperatures controlled at 35–55 °C;

— Gas pressure in the treatment system is maintained within the range of 4–9 bar to ensure stable transport;

— Moisture content after primary treatment reaches 60–120 g/m³, requiring mandatory cooling;

— The plant’s energy efficiency enables the generation of up to 2.5–4.0 million m³ of biogas annually;

— The potential output is equivalent to savings of 1,200–1,800 tonnes of fuel equivalent per year.

Within the ‘EVROPROM’ project, the key focus is on stabilising the temperature and humidity conditions of the HVAC system, as it is this stage that determines the quality of the final product, reduces losses during drying and ensures economic efficiency.

The cooling process unit, where the quality of biomethane is determined

Control of this stage ensures the stability of biomethane storage, transport and further use, setting the quality parameters at the output of the entire line. 

— The gas temperature after compression can reach 35–48 °C, which increases the load on the drying process;
— Cooling to 6–10 °C allows up to 85–92% of residual moisture to be condensed;

— The drying heat exchanger operates at a temperature difference (ΔT) of 5–9 K to effectively stabilise the parameters;
— The gas flow rate in the system reaches 900–1,400 m³/h, requiring a stable supply of cooling;

— Efficiency losses without cooling can reach 12–18% in terms of final product quality;

— Energy costs for drying are reduced by €6,000–9,000 per year at a stable circuit temperature;

After purification, biogas retains a high moisture content and requires precise cooling before being fed into the treatment and storage system, where the chiller must ensure predictable temperature conditions and efficient moisture condensation.

A compact solution with rapid commissioning and autonomous control logic in Ukraine 

EVROPROM was tasked with finding a solution that would integrate seamlessly into the existing production line without additional engineering modifications and ensure the fastest possible commissioning.

— Autonomous system operation without the need for external hydraulic units or additional piping;

— Quick connection to the heat exchanger with a minimum installation time of 6–12 hours;
—
— Stable operation at 70–110% load during peak moments of the production cycle;

— Compact footprint of 3–5 m² without compromising performance;

— Energy consumption reduced by 8–14% compared to standard solutions;

— Capital costs for integration reduced to €5,000–8,000 thanks to the ready-made module.

For Biogas Energy—Ternopil, this meant receiving equipment that fully met the process parameters, with an emphasis on reliability, ease of operation and predictable performance under real production conditions.

DAIKIN chiller with complete hydraulics 

The project is based on a DAIKIN EUWAB24KBZW1 chiller with a cooling capacity of 55.3 kW, supplied as a fully ready-to-operate module, which allowed the system to be integrated into the production line without additional modifications and with minimal commissioning time.

— A cooling capacity of 55.3 kW ensures stable heat exchanger operation under variable gas loads of up to 1,200 m³/h;
—
— Two DAIKIN scroll compressors operate within a 40–95% load range, reducing peak energy consumption;

— 2 refrigeration circuits enhance reliability and maintain up to 65% of capacity whilst one is being serviced;

— A built-in GRUNDFOS pump provides circulation of up to 6–9 m³/h without additional equipment;
— A 55-litre buffer tank stabilises the system and reduces compressor start-up frequency by 20–30%;

— A low operating time of 1,200–1,300 hours allows for a projected service life of over 10–12 years.

This solution has succeeded in reducing capital and operating costs by €6,000–12,000 through rapid integration, minimisation of downtime and optimisation of the cooling system’s operation.

The system is implemented using an optimised cold distribution scheme developed by EVROPROM, which minimises energy losses and ensures high operational efficiency at all stages of the process cycle.

— The chiller produces chilled water at a temperature of 6–9 °C to ensure stable heat exchanger operation;
— The pump feeds the coolant directly to the drying unit without any intermediate pressure losses;

— Moisture is condensed in the heat exchanger to a level below 10–15 g/m³;
—
— Lowering the gas temperature improves the stability of subsequent compression and storage;
—
— The system’s energy consumption stabilises within the range of 18–26 kW/h during the operating cycle;

— Total savings on the drying process reach €7,000–11,000 per year due to cooling efficiency.

The engineering logic of the solution ensures stable operation even when the composition and volume of biogas change, which is critical for the continuous process at the ‘Biogas Energy—Ternopil’ plant. The chiller has been tested against 8 key parameters with connections to water and electricity, guaranteeing reliability, predictable operation and safe system start-up.

The solution enabled the system to reach operational modes immediately after integration and ensured the predictable operation of the entire high-tech system.
