Гелиоколлектор горячего водоснабжения и вентиляции

Abstract

Solar collectors intended for hot water supply needs are widely used today. However, the territorial position of Ukraine prevents their efficient use during the cold period of the year. This reduces their utilization factor and increases the payback period. The use of solar collectors as the recuperators of exhaust air will allow for their efficient operation during the heating season. This becomes possible because the cold air is heated by the indoor waste air heat particularly in the solar collector (heat transfer process) and the preheated air is delivered from this solar collector to the room. In the solar collector-recuperator the cool air circulates in the tube space and the hot air circulates in the intertube space and two flows never mix together. This allows us to use the ventilation and hot-water supply solar-heat collector actually in all the premises including residential buildings and offices. The tests showed that solar collectors used as the recuperators of exhaust air can heat the outside air in the range of minus 10 ̊ C to (4,55–6,07) ̊ C. The range is defined by the air exchange value in the room. Thus, the heat consumption for heating is considerably reduced thanks to the fact that the heated air is supplied through the forced ventilation system into the room.
