摘要

the invention relates to a ventilation and air conditioning, namely to remove ice or water from the heat exchanger equipmentaimed at increasing the energy efficiency of the heat exchanger with low adverse temperatures of cold flow.the essence of the invention is that the negative temperature outdoor air control hydraulic resistance u0432u044bu0442u044fu0436u043du043eu0433u043e channel heat exchangerif you increase the value of the hydraulic resistance to the threshold, which determines the allowable number of freezing of condensate in the u0432u044bu0442u044fu0436u043du043eu043c channel, u0432u044bu043au043bu044e hope u043fu0440u0438u0442u043eu0447u043du044bu0439 fandirect the air to exit the channel u0432u044bu0442u044fu0436u043du043eu0433u043e u0440u0435u043au0443u043fu0435u0440u0430u0442u043eu0440u0430 in u043fu0440u0438u0442u043eu0447u043du044bu0439 channel and control the temperature differential at the input and output channel u0432u044bu0442u044fu0436u043du043eu0433u043e u0440u0435u043au0443u043fu0435u0440u0430u0442u043eu0440u0430,upon reaching the reference value difference temperatures represent flow of cold air in u043fu0440u0438u0442u043eu0447u043du044bu0439 channel and u0432u044bu0442u044fu0436u043du043eu0433u043e air out.
