Abstract

The invention relates to the technical field of fresh air, particularly provides a fresh air system, and aims to solve the problems of influence of an existing fresh air system on indoor temperature and humidity adjustment at the same time. The fresh air system comprises an air humidity adjusting device and a heat exchanger, the air humidity adjusting device selectively communicates with the first air duct, the second air duct, the third air duct and the fourth air duct so as to switch the operation mode of the fresh air system, and the heat exchanger stretches across the first air duct and the fourth air duct and is used for adjusting the temperature difference of two inner air flows. And the working medium in the two air channels is driven to circularly flow in the two air channels. In winter, the indoor and outdoor temperature difference is large, at the moment, part of the heat exchanger located in the first air duct serves as a condensation end, part of the heat exchanger located in the fourth air duct serves as an evaporation end, a working medium in the evaporation end absorbs heat and evaporates, then flows to the condensation end and releases heat and condenses at the condensation end, and outdoor low-temperature air enters a room from an indoor air supply opening after being heated in the process. Therefore, the purpose that the fresh air system only exchanges air and does not exchange heat is achieved.

Description

technical field [0001] The invention belongs to the technical field of fresh air, and specifically provides a fresh air system. Background technique [0002] As people's requirements for indoor air quality are getting higher and higher, simple air-conditioning systems can no longer meet people's needs for fresh air. Therefore, fresh air systems have become more and more popular, especially in northern areas with poor air quality. [0003] In transitional seasons, the utilization rate of the fresh air system is the highest, but the simple fresh air system can only perform simple purification treatment on the outdoor air. When the indoor and outdoor temperature difference is large, the fresh air input from the outside will affect the indoor temperature. For example: in winter, the outdoor low-temperature air is fed into the room by the fresh air system, the indoor temperature can never reach the target temperature set by the user, and the air conditioner continues to cool.
