Paper Details How DX AC Systems Can Meet ASHRAE IAQ, Energy Standards

The brief discusses direct-expansion air-conditioning "discharge-air-temperature" reset, plus continuous capacity modulation for refrigeration circuits.

Engineers designing HVAC systems for use in schools, hospitals, factories, and office buildings face a host of conflicts and tradeoffs when trying to comply with both ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings, and ANSI/ASHRAE Standard 62.1, Ventilation for Acceptable Indoor Air Quality. To help engineers achieve balance between the two, Rawal Devices Inc., manufacturer of temperature- and humidity-control solutions for 
industrial-, institutional-, and commercial-building applications, recently published a technical brief, “No More Tradeoffs: Designing DX AC Systems to Meet ASHRAE’s IAQ and Energy Savings Standards.”

The brief explores advantages and disadvantages of available solutions and reveals how making the right selection can improve a building’s energy efficiency and indoor-air quality (IAQ) without compromising performance.
