ANSI/AHRI 1060-2005 Performance Rating of Air-to-Air Exchangers for Energy Recovery Ventilation Heat Equipment
|
This standard establishes a single set of
requirements for the testing and rating of air flow rate, sensible,
latent, and total effectiveness, and pressure drop of air-to-air energy
recovery ventilation equipment; whereby, equipment performance ratings
can be compared from product to product. |

| AHRI Guidleine V: Calculating The Efficiency Of Energy Recovery Ventilation And Its Effect On Efficiency And Sizing Of Building Hvac Systems |
The purpose of this guideline is to establish a
method of calculating the energy efficiency of applied Energy Recovery
Ventilation components and of heating, ventilating, and/or
air-conditioning systems utilizing such components at selected
operating conditions. It also provides guidance on proper sizing of
cooling and heating equipment when such energy recovery components are
applied. |

| Gard Analytics - ASHRAE 1254-Rp Evaluating The Ability Of Unitary Equipment To Maintain Adequate Space Humidity Levels, Phase II |
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. |

|
| Matching the Sensible Heat Ratio of Air Conditioning Equipment with the Building Load SHR |
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. |
