The coolers have efficiencies ranging from 0.81 to 0.95.
For enclosures that can be exposed to hot and cold temperatures, the Peltier devices can be wired to cool and heat. In these units, the thermoelectric devices run with polarity reversed, letting them move heat from outside the enclosure to the inside when conditions warrant.
The AHP-2250 provides 2,060 btu∕hr (605 W) of cooling, while the AHP-3250 offers 2,600 btu∕hr (765 W), and the AHP-4250 generates 2325 btu∕hr. When configured to provide interior heating, the AHP-2250 generates 3,750 btu∕hr of heat capacity, the AHP-3250 provides 5,320 btu∕hr, and the AHP-4250 puts out 2455 btu∕hr. EE&T
