ANALYSIS OF A SOLAR PLANT FOR THE PRODUCTION OF HOT CONSUMPTION WATER FOR THE HOSPITAL

Abstract

The paper presents and analyzes the efficiency of a solar plant for the production of thermal energy, ie the preparation of hot water (DHW) in the hospital in Subotica. At the analyzed facility, solar collectors provide the complete needs of the hospital for hot water from spring to autumn, while in the second part of the year, the required thermal energy is obtained from additional sources. The solar plant consists of 144 solar collectors, where the total gross area of the collector is 362.6 m 2 and the installed power of the plant is 253.8 kW. During the analyzed period from 2014 to 2017, a total of 558 MWh of thermal energy was produced, ie energy equivalent to 58,613.43 kg of fuel oil was saved. This thermal energy was used for the needs of the kitchen, laundry, central sterilization, heating of the operating room, and etc.
