Abstract

The invention relates to the technical field of fresh air, in particular to a fresh air system. The fresh air system aims to solve the problems of influence of an existing fresh air system on the indoor temperature and humidity adjustment. The fresh air system comprises an air humidity adjusting device and a heat exchanger, wherein the air humidity adjusting device selectively communicates with afirst air duct, a second air duct, a third air duct and a fourth air duct so as to switch the operation mode of the fresh air system, and the heat exchanger stretches across the second air duct and the third air duct and is used for driving a working medium in the heat exchanger to circularly flow in the two air ducts by utilizing temperature difference of air flow in the two air ducts. The indoorand outdoor temperature difference is large in summer, the portion, which is located in the second air duct, of the heat exchanger serves as an evaporation end, the portion, which is located in the third air duct, of the heat exchanger serves as a condensation end, the working medium in the evaporation end flows to the condensation end after absorbing heat and evaporating, heat release and condensation are carried out at the condensation end, in the process, outdoor high-temperature air enters an indoor space from an indoor air supply port after being cooled, so that a precooling effect on the outdoor air is achieved, and the purpose that the fresh air system only exchanges air but 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 summer, outdoor high-temperature air is fed into the room by the fresh air system, and the indoor temperature can never reach the target temperature set by the user, and the air conditioner continues to cool.
