An air heat unit with an external evaporator and a wind energy power system

Abstract

An embodiment of the present disclosure provides an air-heating unit with an external evaporator and a wind energy power system, which belong to the technical field of mechanical engineering, wherein the air-heating unit is applied to a wind energy power system including a wind turbine, and the wind turbine includes a tower and a The nacelle installed on the top of the tower, the wind heat unit includes an evaporator and a fixing assembly for rotatably fixing the evaporator outside the tower, the evaporator is connected with the nacelle, The rotation of the nacelle drives the rotation of the evaporator. With the wind-heating unit of the embodiment of the present disclosure, by fixing the evaporator outside the tower and connecting the evaporator to the nacelle so that it can rotate with the nacelle, the evaporator can always face the wind. This structural design can make the convective heat transfer outside the evaporator strong, and thus can better avoid frosting.

Description

Technical field [0001] The present disclosure relates to the field of mechanical engineering, and more particularly to an exterior wind heat generator set and a wind energy system external to an evaporator. Background technique [0002] With the improvement of urbanization, the demolition of regional small boilers and the renovation of the management network of the old town. There is a huge gap in my country's urban central heating. In recent years, my country's urban residential heating area has maintained higher speed growth, but my country concentrates on The thermal coverage is still at a lower level. At present, only a centralized heating system in the northern provinces, and there is less than 50% of the average coverage, and there are basically no central heating facilities in the vast rural areas of China and my country. Relying on natural gas stoves, air conditioning, electric furnaces and honeycomb coal, which is heating, and urban centralized heating coverage in develo...

Problems solved by technology

During the working process of the evaporator, the temperature of the evaporator body will drop below zero. At this time, the surrounding moisture will quickly condense into frost. After frosting, the evaporator cannot be in its best working state. If things go on like this, it is easy to reduce the heat pump. The heating capacity and energy efficiency ratio of the unit, resulting in energy loss
