Description

A heat energy recovery device for a new type of high-efficiency full heat exchange fresh air ventilation system

technical field

The invention belongs to the field of fresh air ventilation equipment, and specifically discloses a heat energy recovery device for a novel high-efficiency full heat exchange type fresh air ventilation system.

Background technique

The fresh air system is based on the use of special equipment on one side of the closed room to send fresh air to the room, and then from the other side of the special equipment to discharge it to the outside, forming a "fresh air flow field" indoors, so as to meet the needs of indoor fresh air ventilation. The implementation plan is: adopting high wind pressure, large flow fan, relying on mechanical force to supply air from one side to the room, and using a specially designed exhaust fan to discharge it to the outside from the other side to force the formation of a fresh air flow field in the system. While supplying air, the air entering the room is filtered, sterilized, sterilized, oxygenated, and preheated (in winter). In winter, the fresh air system generally heats the air fed into the room through electric heating wires. In the cold winter, the temperature difference between indoor and outdoor is large, and a large amount of heat energy is consumed for heating the air. The turbid but warm air is exhausted outdoors. At this time, a considerable amount of heat will be lost in the exhaust process. Although there are some energy recovery devices for fresh air systems, they are generally expensive and low in efficiency. Satisfactory energy-saving effect cannot even offset the increased cost, which leads to difficulties in application promotion.
