ClimaCool has introduced a modular chiller that harnesses air and water to achieve simultaneous heating and cooling without geothermal. The Simultaneous Heating and Cooling Air Cooled Heat Pump with Integral Water to Water Heat Recovery offers the benefits of geothermal without well fields or other source/sinks. The chiller operates in three modes: cooling, heating or heat recovery allowing buildings to harness energy already being produced but not used. With separate electric feeds, individual modules within the chiller bank can be taken offline for servicing, expansion or replacement without impacting system performance. The design and off-the-shelf components also allow easier maintenance by service contractors.
