Nov. 19, 2014: Trane Adds Water-Source VRF Systems to Growing Ductless Portfolio
Water-Source VRF Provides Cost Efficient Heating and Cooling for Multi-Occupant Buildings
DAVIDSON, N.C. — Trane, a brand of Ingersoll Rand, has expanded its ductless portfolio to include new Trane® Water-Source VRF Ductless Systems. The company said the new systems provide energy-efficient solutions for multi-tenant and diversely occupied buildings, including commercial real estate, K-12 and higher education facilities.
Trane water-source variable refrigerant flow (VRF) systems use 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.
