Wind heating unit with externally-arranged evaporator and wind energy power system

Abstract

The embodiment of the invention provides a wind heating unit with an externally-arranged evaporator and a wind energy power system, and belongs to the technical field of mechanical engineering. The wind heating unit is applied to the wind energy power system comprising a wind machine; the wind machine comprises a tower frame, and a machine cabin installed at the top end of the tower frame; and thewind heating unit comprises the evaporator and a fixing assembly used for rotationally fixing the evaporator outside the tower frame, the evaporator is connected with the machine cabin, and the machine cabin rotates to drive the evaporator to rotate. The wind heating unit is adopted, the evaporator is fixed outside the tower frame, and the evaporator is connected to the machine cabin, so that theevaporator can rotate along with the machine cabin together, and the evaporator can always face wind; and through the structural design, the convection heat exchange outside the evaporator can be high, and frosting can be well avoided.

Description

technical field [0001] The present disclosure relates to the technical field of mechanical engineering, in particular to an air heat unit with an external evaporator and a wind energy power system. Background technique [0002] With the increase of urbanization rate, the dismantling of small regional boilers and the transformation of pipe networks in old urban areas, there is a huge gap in my country's urban centralized heating. The heat coverage rate is still at a low level. At present, only the main towns in the northern provinces have central heating systems, and the average coverage rate is less than 50%. Rely on independent heating methods such as natural gas furnaces, air conditioners, electric furnaces and honeycomb coal for heating, while the coverage rate of central heating in cities in developed countries such as Finland and Denmark reaches 90%, and the national average level is also above 60%. [0003] my country's urban heating industry still uses coal as the main...

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
