Abstract

The invention provides a fresh air system with a heat exchange core, and the system comprises a shell; a fresh air duct and an air return duct which are distributed in a staggered mode are arranged inthe shell, and the heat exchange core is arranged at the intersection of the fresh air duct and the air return duct; a filtering device is arranged at an inlet of the fresh air duct, a fresh air fanis arranged in the middle of the fresh air duct, and the heat exchange core is located between the filtering device and the fresh air fan; an electric controller is arranged at one side in the shell.A heat exchanger assembly and a humidifying and filtering assembly are arranged at the other side of the fresh air duct; an air return fan is arranged at the side, close to the heat exchange core, ofthe air return duct, and a filtering component is arranged at the other side. The invention also discloses an air conditioner, and the air conditioner comprises the fresh air system; the fresh air system is provided with the heat exchange core. By improving the cleaning effect of the core body, the cleanliness of circulating gas is improved, the adverse effect of dust on use is reduced, and the service life of equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular to a fresh air system and an air conditioner with a heat exchange core. Background technique [0002] The total heat exchange core is an energy-saving device used for air-conditioning exhaust air energy recovery. When it is applied to the air-conditioning system, it can use the exhaust air to pre-cool and dry the fresh air in summer, and preheat and humidify the fresh air in winter, so that the load of fresh air is significantly reduced, thereby Saving energy consumption of cooling and heating systems is very beneficial to small system scale, saving operating costs and reducing peak power consumption. [0003] The existing total heat exchange core configured in the air conditioner body is formed by stacking multiple total heat exchange chips, and the upper and lower surfaces of each total heat exchange chip provide fresh air channels and exhaust air channels respectively. ...
