The Coolerado Cooler is an all-indirect evaporative air conditioner that, like other evaporative coolers, relies on the latent heat of vaporization for cooling. Unlike most other systems, though, the Coolorado does not introduce moisture into the building, and thus can be used in conjunction with conventional compression-cycle air conditioning. The system relies on a thermodynamic cycle called the Maisotsenko Cycle (M-Cycle) that rejects heat and moisture and delivers dry, chilled air to the building. Units described here do not use refrigerants. Stand-alone Coolerado air conditioners with ECM motors deliver 3–6 tons of cooling, using 450–710 watts of electricity. Water consumption of the largest unit is comparable to or slightly lower than that of direct evaporative coolers—as much as 12 gallons per hour at peak load, but typically averaging about 4 gallons per hour over the cooling season. The smallest unit, the M30, uses 450 watts (which can be supplied with 2–4 PVPhotovoltaics. Generation of electricity directly from sunlight. A photovoltaic (PV) cell has no moving parts; electrons are energized by sunlight and result in current flow. panels) and is adequate to cool a small home (<1,500 ft2). Coolerado air conditioners are primarily marketed for commercial applications. The manufacturer claims that they use 50%–90% less energy than standard refrigerant-cycle air conditioning and have an Energy Efficiency Rating (EEREnergy-efficiency rating or energy-efficiency ratio. As most commonly used, EER is the operating efficiency of a room air conditioner, measured in Btus of cooling output divided by the power consumption in watt-hours; the higher the EER, the greater the efficiency.) of over 40.
