9、al plant, institutional buildings, hotel etc. Make use the heat source water that has “waste heat” in it. This waste energy can be captured and recycled by means of heat pump. Used to produce hot water for showers, kitchen and laundry in hotel application. The return chilled water from the air-conditioning system can be used as the heat source. Both the hot water and chilled water produced by heat pump are being used. 80 to 200 kW R407C or R134aTandem scroll compressorWater to Water Heat PumpPACS Max h
