System of initial heating of the incoming air of the air-to-water heat pump

摘要

the invention relates to pre heating the intake air system heat pump air - water, containing the spiral heating electric cable, characterized by that, that is mounted to the inner surface inlet pipe (6) of the air heat pump (7) air water under in arstwu0105 thermal insulation (8) and is a scaffold (2),made of steel wire with a diameter of not more than 3 mm, which is spirally embedded heating electric cable (3) and plug (5), whereby the diameter of the scaffold (2) and a heating cable (3) at the inlet of the intake air to the inlet pipe (6) is smaller than the diameter a scaffold (2) and the heating cable (3) on a combination of inlet pipe (6) of the heat pump (7).
