The Newest All-Indoor Solution by United CoolAir

Indoor air quality can be adversely affected by many factors. Indoor pollutants can lead to a variety of health risks, especially for those already susceptible to such factors. Studies show that introducing conditioned outside air can lead to better health and performance of occupants in a variety of settings. ASHRAE 62.1-2016 requires minimum OSA per code. Alpha Aire is the first choice in introducing fresh air into buildings for a simple and quick installation for challenging or existing retrofit applications.

United CoolAir uses high-density 2″ thermal/acoustic insulation Solid Double Wall along with low airflow to greatly reduce noise for near occupant operation. Critical components are isolated out of the air stream for longer life, and thermal breaks prevent unwanted condensate formation. Single point electrical power and 8″ flex duct make for a low cost installation. The sheet metal is G90 galvanized steel with optional wet paint finish for durability and long life.

Alpha Aire Control Sequence

When the dry bulb at the unit’s temperature sensor exceeds the dehumidification (cooling) set point, the compressor will be turned on with the reversing valve set in the dehumidification (cooling) position.  The supply air will be conditioned by the enthalpy wheel and the refrigeration system.

When the dry bulb at the unit’s temperature sensor falls below the heating set point, the compressor will be turned on with the reversing valve in the heating position.  The supply air will be conditioned by the enthalpy wheel and the refrigeration system.

When the dry bulb at the unit’s temperature sensor is between the dehumidification (cooling) and heating set points, the compressor will be turned off.  The supply air will be conditioned only by the enthalpy wheel.

The Final Word in Low CFM Outside Air Systems

Today’s commercial buildings are designed and built with energy efficiency in mind. New construction techniques and materials used for the shell of the building minimize heat gains and losses and prevent the unwanted infiltration of moisture-laden outside air from entering the space, thereby decreasing the cost of space conditioning. To maintain the latest ASHRAE Standard 62.1-2016 ventilation requirements, owners/operators of commercial buildings generally have to depend on up-sized packaged rooftop HVAC systems not only to condition the recirculating air but to also bring in fresh OA to meet IAQ requirements. This results in larger equipment investments and higher operating costs.

The Solution is Alpha Aire

A simpler, more effective solution is a 100% dedicated outside air system (DOAS) from United CoolAir Corporation working in conjunction with a space sensible heating/cooling system. United CoolAir Corporation’s Alpha Aire 100% outside air unit is a stand-alone system designed to meet the OA requirements for today and years to come. Traditional HVAC systems are designed primarily to handle design sensible loads and are not adequately designed for the high latent loads produced by outside air. The Alpha Aire is designed to exclusively handle the large latent ventilation load and deliver “neutral” air of 72°F to 75°F @ 50% RH. Alpha Aire’s supply air dew point design temperature is lower than standard air conditioners to remove the maximum amount of moisture before delivery to the space.
