This diploma thesis deals with design of chiller for specific aplication – The City Theatre in Brno. The solving equipment of cooling appliance includes complete design of heat exchanger, battery cold and dimensioning of pipeline system used for various media. One part of design is also choice of individual coolant pumps, which guarantee necessary cirkulation of cooling medium in a certain pipeline routes. Selected battery cold in this administration reduced the size of the necessary cooling resources, therefore the cost of implementation. Everything is processed in calculating software. The resulting proposal is also drafted in the design program and will serve as one of the bases for subsequent implementation.
