Ceiling type fresh air ventilator

Abstract

The invention discloses a ceiling type fresh air ventilator. The ventilator comprises a shell, an outdoor air inlet, an outdoor exhaust opening, an indoor air returning opening and an indoor air supply opening. A fresh air channel and an air returning channel are arranged in the shell in a crossed manner, the two ends of the fresh air channel are communicated with a fresh air filtering part and an air inlet draught fan, the fresh air filtering part is communicated with the outdoor air inlet, the air inlet draught fan is communicated with the indoor air supply opening, the two ends of the air returning channel are communicated with the indoor air returning opening and an air returning draught fan, and the air returning draught fan is communicated with the indoor air returning opening; a heat exchange core body is arranged at the crossing position of the fresh air channel and the air returning channel, the heat exchange core body internally comprises a fresh air hole way and an air returning hole way, the fresh air hole way and the air returning hole way are each formed by sequential alternative overlapping of a plurality of ventilation parts and a plurality of seal parts at intervals from bottom to top, and the fresh air hole way and the air returning hole way are not communicated. The fresh air ventilator has the higher heat exchange rate and the higher air purification rate, the structural design is exquisite, arrangement is reasonable, the service life is long, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of air purification and ventilation, and in particular relates to a ceiling type fresh air blower. Background technique [0002] Fresh air blower injects outdoor air into the room after dust removal, temperature adjustment, and humidity adjustment to replace indoor turbid air and maintain the circulation of indoor and outdoor air, thereby improving indoor air quality and providing fresh air needed for human health. The fresh air sent into the room through the system will gradually replace the dirty air in the room, thereby improving the indoor air quality. Ceiling-type fresh air fans are miniaturized equipment, which are mainly hoisted under the floor and above the ceiling. [0003] Some ceiling-mounted fresh air fans currently on the market have complex structures, unreasonable layouts, and are inconvenient to use. They also use aluminum heat exchange cores.

AI Technical Summary

Problems solved by technology

[0003] Some ceiling-mounted fresh air fans currently on the market have complex structures, unreasonable layouts, and are inconvenient to use. They also use aluminum heat exchange cores. After a period of operation, condensed water will form on the surface of the aluminum heat exchange cores, which will affect heat exchange. The working effect of the core body may even damage the heat exchange core body and shorten the service life of the ceiling-type fresh air machine. Complicates the structure; in addition, the indoor return air outlet of some ceiling-mounted fresh air fans sold on the market is not equipped with filter elements, and the pollution particles contained in the indoor return air enter the heat exchange core, which is easy to damage the heat exchange core and shorten the ceiling-mounted fresh air intake. The service life of the new fan
