Abstract:

A cooling system and method for an outdoor electronics enclosure includes an air conditioner controlled to operate during off-peak hours, so as to pre-cool batteries. The cooled batteries keep the enclosure cool during peak hours so that it is not necessary to run the air conditioner when electricity prices are at their peak. A clock or light sensor determines the time of day. A controller has stored data indicating the peak hours when electricity costs more.

International Classification:

F24F 11/053

US Classification:

454258

Abstract:

An enclosure houses heat-producing equipment and includes an air conditioner, a fan, and at least one controller for controlling the air conditioner and the fan. The controller runs the air conditioner when a temperature of the interior is greater than or equal to an on temperature and turns the air conditioner off when the temperature of the interior is less than or equal to an off temperature. If the ambient temperature outside the enclosure is less than the off temperature and the air conditioner is off, the controller turns the fan on until the temperature of the interior is less than the off temperature by a first amount and then turns the fan off. Also a method for controlling the temperature of an enclosure using an air conditioner and a fan.
