The research was conducted in the framework of the project known as „Coupon for innovations - support for the smallest companies”, endorsed by the Polish Agency for the Development of Business, and it had the following objectives: to assess the efficiency of the collector and reliability of the applied parameters such as the force of warm air blast, temperature increase depending on the intensity of solar radiation and the angle of the collector setup, influence of ambient temperature on the collector’s efficiency and heat loss, the quantity of relative humidity reduction correlative with the heating up of the flowing air. Collector in a standard installation position - on a vertical wall. The assessed solar air collector was exposed to solar radiation and the following parameters were measured in the course of study: intensity of solar radiation falling on a vertical surface and on the collector’s surface (the collector was installed in vertical position, which is a standard installation method), temperature and velocity of air flowing into the collector as well as temperature and velocity of air flowing out of the device. The studies indicate that already at the radiation value of 100 W m-2 the collector worked efficiently and heated up the flowing air by about 5oC. This temperature increased together with radiation and reached the value of 20oC at the radiation of 800 W m-2. The analysis of the collector’s efficiency showed that during its work (proper temperature and radiation) the efficiency remained at a satisfactory level from 42 to 46%.
