Fresh air fin system and building thereof

Abstract

The invention provides a fresh air fin system which comprises an air supply duct, an air return duct and a heat accumulator, a heat accumulation material, the air supply duct and the air return duct are arranged in the heat accumulator, the air supply duct and the air return duct are arranged in the heat accumulation material, the air return duct transmits heat to the heat accumulation material, and the heat accumulation material transmits heat to the air supply duct; fins are arranged outside the air return duct, and the heights of the fins are gradually increased in the flowing direction of fluid in the air return duct. The invention provides a new fresh air system, so that the heat storage medium integrally absorbs heat uniformly in the fluid flowing direction, and the condition of non-uniform heat absorption is avoided.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to a fresh air system and a building thereof. Background technique [0002] The heat storage materials of the heat accumulators of the prior art all have the same heat storage capacity, which leads to uneven heat storage of the heat accumulator as a whole, and may cause excessive heat storage positions. [0003] For example, if the temperature near the high temperature fluid inlet is too high, the local life of the fluid pipeline and the heat accumulator will be reduced. [0004] Ventilation is the key to improving indoor air quality, using fresh outdoor air to dilute indoor air pollutants and reduce their concentrations. However, if the outdoor air is seriously polluted (such as sandstorms or high concentrations of inhalable particles or other pollutants), it is necessary to avoid direct window ventilation. At present, the per capita area of ​​residential buildings is ...
