Munters Corp., Dehumidification Div.-Commercial: Commercial Heat Pump

August 28, 2006


A self-contained water-cooled desiccant heat pump reduces operating costs by 30-50 percent compared to traditional rooftop units, claims the manufacturer. In the cooling mode, the system extracts heat from the air and rejects it into a water loop through a coaxial heat exchanger. This heat can be recovered to generate hot water for general purposes, or simply be rejected out of the building via a cooling tower. In the heating mode, the unit reverses the cycle, extracting heat from the water loop through the coaxial heat exchanger, and utilizing a common air coil to heat the building space. The HCU water-cooled heat pump can operate in cold weather because it extracts heat from the water source instead of the ambient air. Utilizing a DDC controller and a VFD supply motor to blend a mixture of return air and outside air, this system operates effectively, even when the ambient temperature is approaching 10°F. This new unit is available with gas or electric postheat with return air and night setback modes.
