Abstract

To cool liquid a refrigerating machine - chiller is used. The chiller compressor is the main consumer of electric power. To reduce energy consumption the schemes with natural cooling - free cooling are used. Energy consumption reducing is caused by partial or full dead time of the compressor when the equipment is operating at natural cooling. Reducing operating costs allows saving means, but when capital costs are increased, the payback period is one of the criteria to take a decision. The paper presents the method of calculation of the payback period of natural cooling application in order to reduce the chiller power consumption. Using a method offered the customer may analyze investment profit of free cooling, and a contractor may reason the application of one or another circuitry of free cooling.
