What makes this product green?

  • Renewable energy equipment
  • Energy-conserving equipment


The SunChiller provides air cooling as a primary output, with space and water heating also possible. The system uses vacuum-tube heat-pipe solar thermal collectors to heat water, which drives an absorption chiller to provide cooling. Water serves as the "refrigerant," avoiding the use of ozone-depleting compounds. A SunChiller can be used in a hybrid system to provide space heating and water heating in addition to absorption cooling. The system can be configured to provide solar-powered absorption cooling during electrical peak hours, with a more conventional electric chiller taking over during lower-cost off-peak hours. The system combines vacuum-tube solar-thermal collectors, an insulated storage tank, a single-effect water-heated absorption chiller, a cooling tower, an energy management system, and air handler. It is available as an integrated system for commercial buildings requiring air conditioning capacity of at least 10 tons.
