Abstract
While various actions for prevention of global warming are carried out, higher efficient chiller development is expected. In this development, we adopted inverter control and Lorentz cycle in the field of lower-capacity screw chiller and aimed for performance of development machine to become equal with large-capacity chiller. It became clear that developed machine showed 1.3-1.5 times performance in comparison with conventional one at full load, 1.3-3 times performance at partial load and to have superior economical efficiency and environment friendly effect.
