Obzor metodov snizheniya stepeni obledeneniya i ottayki ispariteley teplovykh nasosov

In presentday world heat pumps are used still wider both in civil sphere and in industry. But the efficiency of heat pumps operation depends greatly on environment parameters. At low temperature of outdoor air the heat exchange surface of a heat pump evaporator begins to get covered by a frost layer that influences much the efficiency of the plant operation as well as its life time. So, the problem to search for thawing methods is urgent as well as for methods to prevent the frost formation on heat exchange surfaces. The paper examines the major wellknown methods of thawing, new developments and investigations in this sphere. The advantages and disadvantages of the methods presented are discussed. The most perspective and applicable methods are marked out. The criteria of selection were as follows: the possibility to thaw out using the methods without stopping operation, efficiency and the simplicity of realization.
