Trane Adds Water-Source VRF Systems
Trane expanded its ductless portfolio with its new Water-Source variable refrigerant flow (VRF) Ductless Systems, providing energy-efficient HVAC for multi-tenant and diversely occupied buildings.
Trane water-source VRF uses water as the energy exchange medium to heat and cool the system’s condenser. Using adjacent water or geothermal sources, water-source VRF can draw upon stable water temperatures to dissipate heat during peak cooling periods and act as a heat source when in heating mode. Alternatively, systems can be connected to a cooling tower to reject energy from the building or a boiler to add heat in colder climate applications.
Water-source VRF retains its heating capacity even as entering water temperatures fall because the drop is not as dramatic as it is with low ambient air temperatures. As a result, water-source VRF delivers up to 30.1 integrated energy efficiency ratio, 27.4 simultaneous cooling and heating efficiency and up to 48 tons of capacity, says Trane.
Water-source VRF allows building occupants to adjust the temperature in individual spaces, and it also enables building managers to calculate the actual energy use of each leased space. Building managers have the flexibility to turn off airflow to unoccupied areas.
