Laboratory energy recovery selection factors

Brown (1990) recommends that a

Heat recovery coil should be incorporated for geographic regions with high preheating/humidification requirements.

a.Locate coil upstream of preheating coil in cold climates.

b.Coil can be located downstream of fan in non-severe climates to maximize benefits of pre-cooling where applicable.

The American Conference of Governmental Industrial Hygienists Industrial Ventilation: A Manual of Recommended Practice (1995) discusses issues in selecting heat exchangers.

Several factors are important in the selection of the appropriate heat exchanger. A partial list is as follows:
