Abstract. A solar thermal module intended for thermal driving of an absorption refrigeration machine for air conditioning of animal raising buildings was constructed and experimentally tested. The maximum temperature level of the heat agent in the module under the conditions of a clear and warm summer day of average solar radiation 950-970 W/m2 was determined. The effect of the mounting angle of the solar-thermal module on the maximum temperature levels of  the heat agent circulating inside it was studied. Regression relationships between the maximum temperature of the heat agent in the thermal module and the theoretical heat coefficient of a conceptual absorption refrigeration machine, heat-driven by a solar thermal module, were determined
