Abstract

The advantages of use of an antifreeze as a cooling medium in air conditioning systems are shown. The sequence of design steps of the pump installation for antifreeze circulation is presented. Four versions of pump installations for antifreeze circulation are compared. It is shown that in case of proportional control of the head of pumps a decrease in energy consumption up to 49 % from that in the uncontrolled pump installation is possible.
