- The newest VG and S Series Chiller adopts both low GWP R513a and ultra-low GWP R1234ze refrigerants, empowering seamless energy transitions in Hong Kong
- The latest Top Flow VRF air365 Max Pro and Side Flow VRF air365 SideSmart™ boast low-carbon and energy-efficient benefits
Empowering Seamless Energy Transitions in Hong Kong with Low-GWP Refrigerants
- The Direct-drive VSD Centrifugal Chiller VG Series features a gearless direct-drive two-stage compressor, eliminating the mechanical loss of speed-increasing gears found in conventional compressors. This design enhances efficiency and energy savings, making it ideal for commercial and industrial applications.
- The Centrifugal Chiller S Series features proprietary centrifugal two-stage compression technology and optimizes the use of low-temperature cooling water to enhance performance, allowing the minimum inlet temperature to reach 12°C. Depending on the model, it offers a broad capacity range from 300 to 3000RT to meet various business or building requirements.
Tailoring Energy-efficient HVAC Solutions for a Greener Future in Hong Kong
In addition to sustainable refrigerants, Johnson Controls-Hitachi Air Conditioning is committed to delivering energy-efficient HVAC solutions, aligning with Hong Kong's goals of achieving carbon neutrality in its Climate Action Plan 2050. The following products are already available in Hong Kong:
- The Hitachi air365 Max Pro system sets industry standards with its high efficiency, Japanese design and engineering. Equipped with Hitachi's patented direct capacity control technology SmoothDrive 2.0, it enhances energy efficiency, temperature stability and ensures smoother compressor operation. SmoothDrive 2.0 significantly improves energy efficiency by reducing energy consumption by up to 39% at 33% part-load operation and uses 10% less refrigerant on average, ultimately reducing energy usage and carbon footprint by 47%. Featuring a new heat exchanger and gas injection scroll compressor, this unit achieves a Best-in-Class Energy Efficiency Ratio (EER) of up to 5.60 and Coefficient of Performance (COP) of up to 5.31.
- The Hitachi air365 SideSmart™, the world's first slim modular Variable Refrigerant Flow (VRF) unit, is designed to adapt to diverse space and capacity needs. Its modularity allows for connection of up to four units, offering a capacity range of up to 72 HP and a combined cooling capacity of 200kW. Its slim modular design allows larger capacity air conditioning to fit in anywhere, making it one of the most versatile VRF units available on the market. The air365 SideSmart™ won the Energy Conservation Grand Prize and Minister of Economy, Trade and Industry Award in the Product & Business Model category from the Energy Conservation Center, Japan in 2021.
