Air changes are often cited as a means of preventing condensation in houses with forced ventilation systems often rated 3–5 ACH though without referencing the size of the house. However, where ACH is already greater than 0.75 a forced ventilation system is unlikely to be of use at controlling condensation and instead insulation or heating are ...
Whole house air cleaners are not covered by the CADR specification because the measurement is performed in a standard 1,008-cubic-foot (28.5 m 3) room, the size of a typical house room, which has different airflow patterns than whole-house filters. Measurements are made with the filter running and not running, so particles that naturally fall ...
Standard HVAC system design uses fixed airflow rates to calculate the outdoor air (OA) required in a space. These airflow rates are determined by mechanical code and vary based on expected occupancy and space use. [2] This process of supplying fixed airflow to a space ensures that sufficient OA is present in that space when it is occupied.
In the United States, the efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER) which is defined by the Air Conditioning, Heating, and Refrigeration Institute, a trade association, in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.
