A 25 ton Helisorber (HS25) solar thermal heat pump/chiller has been commissioned at a hotel in Palm Desert, Calif. Other installations of the thermal heat pump/chiller from Energy Concepts, Annapolis, Md., include a 100-ton unit used in poultry processing, a 125-ton unit used at a meat-packing facility, and a 150-ton system in place at a paper mill.

Thermal heat pumps are powered by heat rather than electricity. They deliver energy and cost savings even when powered by natural gas. When chilling is co-produced, the savings increase dramatically.

At the hotel in California, the solar thermal heat pump/chiller is supplied 500,000 BTU/hour of 250°F (121°C) heat from a solar thermal collector. A backup natural gas heater enables continuous operation. The domestic hot water heat output is 800,000 BTU/hour at 130°F (54°C). The chilling co-product is 25 tons at 44°F (6.6°C). All of the output heat from the solar thermal heat pump/chiller goes to heating domestic hot water, so a cooling tower is not required.
