HI AIR KOREA does its best to provide total solutions by offering customized chillers used for the cooling demands of hydrogen charging stations from design, manufacturing and commissioning of entire cooling system.
- FEATURES
Main Chillers for H₂ Charging Machine
AIR COOLED TYPE
WATER COOLED TYPE
General
- Main Chiller supplies brine of -17.5℃ ~ -40.0℃ to cool the H₂ charging machine that produce 875 bar of compressed hydrogen as per SAE J2601 T40.
Construction
- Cost effective operation by saving the power consumption and prolonged lifetime by using inverter compressor (30~70Hz)
- Fast response time control by electronic expansion valve and inverter compressor to cope with the sudden changes of cooling load
- Efficient and stable control by SIEMENS CLIMATIX SERIES PLC which is optimized for air conditioning and refrigeration system.
- Brine buffer tank of 180 Liter @ -40.0℃ ensures stable operation at peak cooling load.
- Two independent refrigerant circuits for redundant operation
- Dual reducing valves and pressure safety valves for Brine buffer tank prevent nitrogen overcharge and hydrogen ingress which can damage the charging machine.
- Air cooled type main chiller can operate independently, which offers simple installation by eliminating other utilities.
- Water cooled type main chiller provides stable operation even at highest summer temperature with lower noise level.
- Proven performance and reliability by test and verification at various ambient conditions (-15 ℃ ~43℃).
- Max noise level of 85 dB(A) at 1 m away from chiller
Maintenance and Quality Assurance
- Simple installation and maintenance
- Pressure and leakage test before delivery
- Performance test before delivery
Sub Chillers for H₂ Compressor
AIR COOLED TYPE
General
- Sub Chiller supplies chilled water of 20.0℃ to prevent H₂ compressor damage and ensure the best efficiency by cooling the H₂ compressor.
Construction
- Two independent refrigerant circuits for redundant operation (140/170/200 kW only)
- Fast response time control by electronic expansion valve to cope with the sudden changes of cooling load from multiple H₂ compressors and water cooled type main chillers.
- Efficient and stable control by SIEMENS CLIMATIX SERIES PLC which is optimized for air conditioning and refrigeration system.
- Brine buffer tank @ 20.0℃ ensures stable operation at peak cooling load.
- Environment friendly & low pressure type R-134a refrigerant can stably operate at highest summer (200 kW only).
- Additional power saving if CMA (Cooling Module Assembly) is provided.
- Max noise level of 85 dB(A) at 1 m away from chiller
- Proven performance and reliability by test and verification at various ambient conditions (-15 ℃ ~ 43℃).
Maintenance and Quality Assurance
- Simple installation and maintenance
- Pressure and leakage test before delivery
- Performance test before delivery
- OPTION
MAIN CHILLER
