Operation is possible with heat source water in low temperature regions! Compatible with renewable energy and unused energy!
The "WDX14AA/25CA/50CA/50DA" is a ceiling-mounted duct-type water-source heat pump unit that achieves high efficiency through the adoption of an inverter compressor. By expanding the low-temperature range of the source water temperature, it effectively utilizes renewable energy (such as groundwater and geothermal energy) and unused energy (such as waste heat from factories, hospitals, and hotels) as a heat source for heating and cooling. It is now possible to operate with source water at low temperatures (below 15°C), improving the energy consumption efficiency for cooling. In buildings with long cooling periods, the energy consumption efficiency for cooling at partial loads is further enhanced, resulting in significant energy-saving effects. 【Features】 ■ Expanded low-temperature range for source water ■ Compatible with renewable and unused energy ■ Improved energy consumption efficiency for cooling ■ Added small-capacity unit (0.5 horsepower type) suitable for air conditioning loads in small rooms ■ Operable temperature range for source water Cooling: 7°C to 45°C / Heating: 5°C to 45°C *For more details, please refer to the PDF materials or feel free to contact us.
