System Integration & Indoor Environmental Quality Subcommittee:

This subcommittee focuses on pre-competitive research that will facilitate or demonstrate better integration of HVAC&R systems and IAQ enhancing equipment into buildings and facilities to provide substantial improvements in energy consumption levels and comfort levels.

This scope encompasses the scopes previously assigned to the System Integration and Indoor Environmental Quality Subcommittees, but are more sharply focused on the effective integrating HVAC&R and IAQ enhancing equipment with buildings and facilities and impact of that equipment on IEQ within the building or facility. Included are system integration design tools; concepts for determining sensible and latent heat cooling loads; designing effective and energy efficient ventilation, thermal distribution (air, secondary loop and hydronic), humidity control and indoor air quality enhancing systems; integration concepts for quieter HVAC&R equipment; utilization of waste heat by or from HVAC&R equipment; and more reliable, compact and affordable indoor air contaminant control equipment and strategies (indoor air quality control strategies, identification of anti-microbial materials for HVAC&R systems, improved concepts for particulate or gas-phase filtration, and enhanced control of temperature, moisture and humidity, ventilation, sound, and air velocity).

HVAC&R Energy Efficiency Subcommittee:

This subcommittee focuses on research needed to provide more energy efficient, compact or affordable HVAC&R equipment and component used in various applications (e.g., unitary and packaged air-conditioners and heat pumps, chillers, refrigeration system, etc.) and to assess the efficiency, compatibility, safety and outdoor environmental impacts of new working fluids (refrigerants, absorption fluids, secondary heat transfer fluids, lubricants, additives, process fluids, etc.).

The scope encompasses the scopes previously assigned to the Equipment Energy Efficiency and the Working Fluids Subcommittees and includes pre-competitive research on heat exchangers, compressors, expansion devices, motors, air handlers, application of working fluids, controls and sensors for control, testing and diagnostics of equipment.
