Johnson Controls-Hitachi Air Conditioning introduces the Hitachi Water Source Variable Refrigerant Flow (VRF) heat pump and heat recovery systems. The new multi-module systems offer the capability of connecting multiple single-module units, ranging from 6-48 tons. In addition to the benefits of VRF technology, these new compact systems deliver the following:
- Reduced first costs
- Compact size enhances exterior appearance while eliminating outdoor noise
- Design flexibility through a variety of configurations
- Ideal for projects with limited space such as high-rise buildings, office buildings, architecturally restricted properties and apartments
- Optimal where outdoor placement is challenging, including coastal areas and extremely cold climates
Maximum design flexibility
All Hitachi VRF indoor units, controls and gateway products are fully compatible with new water source systems for maximum design flexibility. The unified water source units can be used as heat pump and heat recovery units. They are available in 208/230V and 460V in 22 different capacities. Inverter compressor technology achieves high energy efficiency. The AHRI-certified efficiency ratings for the new Hitachi Water Source VRF systems include:
- Integrated Energy Efficiency Ratio (IEER) of 18.9 to 29
- Heating Coefficient of Performance (COP) of 4.00 to 6.30
