This is a new home climate control technology designed to save energy in hot, dry climates. It is essentially a powered whole-house fan, air conditioner, and indirect water heater integrated under one control system. In the summer, the system draws in as much cool outdoor air as possible to meet cooling needs — the air conditioner only kicks on if absolutely necessary. In the winter, a water-to-air heat exchanger extending from the water heater supplies warm air to the system.
Also appropriate for dry climates, the household air cooler
is an evaporative cooling technology that is 100% indirect. It can offer four to six tons of cooling with an energy consumption of 1,200 watts. Its energy efficiency ratio (EER) is 40 or higher, making it two to three times as efficient as the best conventional air conditioners.
