Description

Bottom ponding prevention mechanism of roof air conditioner and control method thereof Technical Field The invention relates to the technical field of roof air conditioners, in particular to a bottom water accumulation prevention mechanism of a roof air conditioner and a control method thereof. Background The installation positions of the mainstream roof air conditioners are all positioned on the roof, condensed water generated by the operation of the roof air conditioners is directly discharged to the roof through the chassis drain holes and then flows into the drain grooves along the roof to be discharged to the ground. In addition to the roof air conditioner, the roof is usually provided with articles such as an exhaust fan, a solar cell panel and the like, and sometimes foreign matters such as fallen leaves, plastic bags, sand and the like exist, which can affect the discharge of roof condensed water and rainwater, and if the foreign matters are accumulated at a drain outlet at the bottom of the chassis, the drain outlet can be blocked, so that water is accumulated at the bottom of the roof air conditioner.
