DOAS air handling unit with heat recovery wheel and passive dehumidification. A dedicated outdoor air system (DOAS) is a type of heating, ventilation and air-conditioning system that consists of two parallel systems: a dedicated system for delivering outdoor air ventilation that handles both the latent and sensible loads of conditioning the ventilation air, and a parallel system to handle the ...
DOAS Diagram. Moisture Removal Efficiency (MRE) is a measure of the energy efficiency of any dehumidification process. Moisture removal efficiency is the water vapor removed from air at a defined inlet air temperature and humidity, divided by the total energy consumed by the dehumidification equipment during the same time period, including all fan and pump energy needed to move air and fluids ...

These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
This air passes into a crossflow plate heat exchanger (B) where a substantial proportion of the sensible heat is transferred to a cool supply air stream. This process brings the extracted air close to saturation. The air then passes to the plenum chamber of the extract fan (C) where a portion of it may be rejected to outside.

As a consequence, a two-tiered health care system is taking deeper root in America. In mainly Republican-led, Southern states, the uninsured rate remains disproportionately high. In sharp contrast, the ranks of the uninsured are falling sharply in states — most run by Democrats — that expanded Medicaid. Obamacare’s Medicaid Expansion Spreads
“My sister knelt down outside the operating room and prayed the whole time,” Foxx said. He said it “was kind of oddly peaceful” being unconscious, adding, “I saw the tunnel. I didn’t ...
