CALCULATION OF THE EFFICIENCY OF A COMBINED SOLAR WATER-AIR HEATER COLLECTOR

Аннотация

The authors of the work proposed a combined solar heating installation for heat and humidity treatment of supply air for greenhouses. The object of study is a combined solar collector for the simultaneous heating of water and air. Heat and humidity treatment of supply air is an energy-intensive technological process that requires huge consumption of thermal energy and water resources. In this work, in order to reduce the consumption of traditional energy for heat treatment of supply air, a combined solar collector is proposed and the results of an experimental study of the operating modes of the installation in the conditions of Karshi are presented. As a result of experimental studies, the high energy efficiency of a combined solar collector in the “water + air” heating mode has been shown. It has been established that the efficiency of the installation is in the range of 0.57-0.80.
