Combined cooling of condenser ensures stabilization of the condensation pressure
and significantly reduces the consumption of cooling water and electricity. Exisiting methods
of calculus of condenseres are applicable for condensers with air or with water cooling and
are not valid when designing a condenser with combined cooling. The economical and
technical recommendations for calculus must be elaborated in dependence of part of the time
of using water or air for condenser unit cooling throughout the year. The mathematical model
describing the operation of all elements of the chiller, as well as their technical and economic
performances has been elaborated. The model includes analysis of the chiller during the
whole period of operation and determines what share of water and air for cooling of
condenser is the best. The analysis takes into account the cost of cooling water, power, energy
costs for transporting the cooling water, for compressor drive, as well as the capital and
operating costs. |
