Air source heat pump with screw compressor for central air conditioning and providing chilled or hot water

Air-cooled screw heat pumps use ambient air as the heat source and water as the transfer medium, delivering both heating and cooling through a single unit. They can replace separate boiler and chiller setups, with hot water temperatures reaching up to 55°C for versatile year-round use. The screw compressor design is paired with a zero-pressure-drop four-way reversing valve, minimizing pressure loss and ensuring reliable switching without the leakage issues found in traditional valves. Equipped with an electronic expansion valve with up to 2,600 regulation steps allows precise control under varying load conditions, optimizing efficiency and maintaining stable operation across a wide range of applications.
