Flat Plate Solar Collector

A flat plate solar collector with cell polycarbonate absorber and transparent cover has been made and its experimental investigation carried out. The collector consists of a wooden box, into which, a layer of heat insulation with a mirror film and 4 mm thick cell polycarbonate sheet, as the absorber, are placed. The coherence between collector’s efficiency, heat carrier and ambient air temperature, as well as intensity of the solar radiation and heat power in the experimental investigation has been obtained. During the experimental examination the maximum temperature of the heat carrier reached 80˚C at the intensity of solar radiation about 0.8 kW/m2 and ambient air temperature around 32˚C. The efficiency of the collector reached 33-60%, depending on the intensity of solar radiation and surrounding air temperature.

Fuel Evaporation

Liquid fuel evaporation was investigated in a premix duct, operating at conditions expected for lean premixed and prevaporized combustion. Results from a flat prefilming airblast atomizer are presented. Kerosine Jet A was used in all experiments. Air pressure, air temperature and liquid fuel flow rate were varied separately, their relative influences on atomization, evaporation and fuel dispersion are discussed. The results show, that at pressures up to 15 bars and temperatures up to 850 K, nearly complete evaporation of the fuel was achieved, without autoignition of the fuel. For the configuration tested, the fuel distributions of the liquid and evaporated fuel sbow very little differences in their dispersion characteristics and were not much affected by a variation of the operating conditions.

Relative Air Humidity

The objective of the work is to substantiate the optimum values of temperature‐humidity regime in cowsheds which are required in designing and exploiting a ventilation system. An equation, which connects relative air humidity of a room with difference between inside and outside air temperature, was developed. Another equation, which shows the greatest allowed difference of temperatures under which water vapour does not condensate on the internal surface of an external partition, was composed as well. By analytical and experimental investigation, it is substantiated that possible minimum relative air humidity in a cowshed is by about 5 % lower than relative outside air humidity. Optimal difference between inside and outside air temperature in the cold period of the year is about 4 °C.
