Total heat exchange device

Abstract

The invention provides a full heat exchange device. The full heat exchange device comprises a shell, a heat exchange core body and a draught fan; a plurality of layers of cavities are formed in the shell, and a plurality of paths of fresh air ducts are formed in the first layer of cavity and the second layer of cavity; a plurality of paths of exhaust air ducts are formed in the first layer of cavity, the third layer of cavity and the fourth layer of cavity, and the fresh air ducts and the exhaust air ducts are independent of each other; each path of fresh air duct is provided with an independent fresh air outlet, and each path of exhaust air duct is provided with an independent exhaust air inlet; the heat exchange core body is in the shape of U and encircles a fresh air fan to be arranged, and an opening of the heat exchange core body faces the outdoor side; fresh air introduced from a fresh air inlet is exhausted through the fresh air fan, enters from the side wall of one side of the heat exchange core body and is exhausted from any fresh air outlet after heat exchange; and indoor exhaust air is introduced from any exhaust air inlet, enters the top face of the heat exchange core body, and is exhausted from an exhaust air outlet by means of an exhaust air fan after heat exchange. The fresh air fan or the exhaust air fan is controlled by a same motor or is correspondingly controlled by two independent motors, and the beneficial effects that efficiency distribution is uniform, and heat exchange efficiency is high are achieved.

Description

technical field [0001] The invention relates to the technical field of air-air energy recovery devices, in particular to a total heat exchange device. Background technique [0002] To maintain comfortable ventilation in a confined space and ensure people's health, fresh air must be introduced in real time or intermittently, and at the same time, the room temperature must be properly controlled to maintain a comfortable indoor environment and meet the needs of normal work and life. However, the traditional fresh air introduction system also increases the air conditioning load, and the exhaust system discharges a lot of waste heat, resulting in a lot of energy waste. In order to solve the above problems, people have developed a device that can simultaneously generate sensible heat and latent heat exchange between fresh air and exhaust air, that is, a total heat exchange device. [0003] The temperature exchange efficiency and fresh air volume of the total heat exchange device...
