CoolBot
CoolBot is an electronic device with a temperature control used with residential air conditioners to override their internal settings. The device allows the air conditioner to continue running below their typical minimum temperature range of 60°F until the temperature specified on a CoolBot is reached. It enables inexpensive and commonly available residential air conditioners designed to cool larger rooms the ability to cool smaller rooms to a specified temperature as low as 36°F without the need of expensive and professionally maintained commercial grade equipment. An ideal room for a CoolBot has a minimum of R25-value rigid-foam insulation[1], is opened less than 6 times per hour[1], and has a large amount of thermal mass to maintain its lower temperature.
For larger rooms with greater BTU requirements, multiple air conditioners can be used. However, each air conditioner will need its own CoolBot.
