Variable Speed Water Source Heat Pumps

Imagine a product that delivers superior comfort and performance while reducing operating cost. The Axiom™ model Variable Speed is Trane’s most advanced water source comfort solution designed to meet these requirements. Trane achieves higher efficiency, reduced sound, improved indoor air quality and high reliability through variable speed compressor and fan technology.

Typical Applications

Water source comfort systems can be applied in office buildings, schools, hotels, apartments, condominiums, and other structures. Application types include boiler / cooling tower, open loop, and geothermal closed loops (ground source and surface water).

Features

New Features and Innovations (October 2012)

A heat-pump system to meet the needs of virtually any building!

Trane Axiom™ water-source heat pumps (WSHP) deliver high-performance heating and cooling with exceptional efficiency: up to 40 EER on select systems. And with all this performance and efficiency, advanced technology makes Trane Axiom water-source heat pumps easy to operate and maintain, resulting in optimal comfort and long-lasting durability.

Performance

• AHRI-ISO 13256-1 certified performance
• Exceeds ASHRAE 90.1 2010 standards for efficiency
• Thermal load matching enables the unit to operate closely to the load requirements of the space

Efficiency

• Full load efficiencies above the ASHRAE minimum
• High part load efficiencies with IPLV’s greater than 30

Indoor Air Quality

• Foil faced insulation for cleanability
• Cleanable dual-sloped non-corrosive drain pan to reduce microbial growth
• Full array of filter options including MERV 7 and MERV 13 to meet LEED EQ Credit 5

Comfort

• Variable speed compressor varies the capacity for thermal load matching
• ECM motor varies supply airflow for superior temperature and humidity control
• Optional enhanced dehumidification control alleviates humidity in problem areas without the need for hot gas reheat

Integrated Controls

• Trane engineered UC400 DDC controller for integration with Tracer™ SC
• BACnet™ MS/TP protocol
• Demand Limiting Mode through Tracer™ SC

Acoustics

• Insulated enclosure for quiet design
• Variable speed fan and compressor reduce sound levels at lower load conditions

Reliability

• Part load operation reduces cyclic operation. Fewer on/off cycles reduce stress of the components.
• Every unit is factory run tested in both cooling and heating cycle

Flexibility

• Units support both boiler/cooling tower and ground source heat exchanger applications
• Supply & return airflow configuration flexibility
• Adjustable supply minimum and maximum airflow settings*
• *Tracer™ TU Service Tool required

Serviceability

• Orifice ring motor mounting device for ease of motor service
• Ducted filter rack option
