Total Energy Efficiency White Paper
When designers are considering the use of energy recovery wheel options, they should consider multiple factors to provide the best overall fit to their budget. Those factors are regional climate zone, energy recovery ratio at the design flow range, and the ability to maintain performance over the life of the equipment.

AHRI Guideline W-2005
The purpose of this guideline is to provide information to support the application of Air-to-Air Energy Recovery Ventilation Equipment (AAERVE). This guideline supports AAERVE that is manufactured using Air-to-Air Heath Exchangers (energy recovery components) rated in accordance with ARI Standard 1060. These recovery components include Heat Pipe Heat Exchangers, Plate Heat Exchangers, and Rotary Heat Exchangers.

ASHRAE Research Project 1254-RP
The objectives of ASHRAE Research Project 1254-RP "Evaluating the Ability of Unitary Equipment to Maintain Adequate Space Humidity Levels, Phase II" were: a) to compare various unitary air conditioning system humidity control configurations in terms of humidity control performance and operating costs; and b) develop guidelines to help identify the important application characteristics and climate factors that determine which option is most appropriate.

SHR Report
There is a mismatch between the SHR of the typical unitary air conditioner and that of the typical building load. The resulting loss of indoor humidity control can cause structural, comfort and health problems. Enthalpy recovery ventilation systems can address these issues by allowing standard unitary packaged cooling equipment to closely match building SHR, while conserving energy and reducing peak demand.
