Abstract

The invention discloses a mechanical defrosting device for an outdoor flat plate type heat exchanger of an air source heat pump system. The mechanical defrosting device comprises the outdoor flat plate type heat exchanger which consists of coiled tubes as well as a framework, a brush head straight rod, a motor, a gear, a frame rail, a frame, a rack and a defrosting brush head which are fixedly equipped with the heat exchanger. According to the mechanical defrosting device disclosed by the invention, the surface of the flat plate type heat exchanger is wavy, so that heat transfer area of the heat exchanger can be effectively improved; and an arc-shaped brush head is correspondingly adopted to be matched with the surface of the heat exchanger better, so that defrosting efficiency is remarkably improved. The mechanical defrosting device is adopted, so that a frost layer can be quickly and effectively removed with low energy consumption when the air source heat pump system continuously and normally operates, and therefore, heating effect of the system is improved, and the indoor temperature is kept stable.

Description

technical field

[0001] The invention relates to the field of HVAC, in particular to a mechanical defrosting device for an outdoor heat exchanger of an air source heat pump system. Background technique

[0002] Air source heat pump, as a kind of heat pump technology, has the reputation of "porter of natural energy", and has multiple advantages such as low cost of use, easy operation, good heating effect, safety and cleanliness. The energy in the ubiquitous air is used as the main power, and the compressor is driven by a small amount of electric energy to realize energy transfer, without complicated configuration, expensive water intake, recharge or soil heat exchange system and special machine room, and it is the same as coal-fired Boiler CO 2 The emission can be reduced by 30% compared with that of traditional heating, which can gradually reduce the large amount of pollutant emission brought by traditional heating to the atmospheric environment, and take into account the pu...
