Atrium air conditioning ventilation system based on heat exchanger and operation method thereof

Abstract

The invention discloses an atrium air conditioning ventilation system based on a heat exchanger and an operation method thereof. The atrium air conditioning ventilation system comprises a heat exchanger, a first draught fan ans a second draught fan, and further comprises a bottom air opening and a top air opening used in summer and winter. The operation method of the atrium air conditioning ventilation system is that in summer, air at the bottom of an atrium sequentially passes through the bottom air opening, the first draught, the heat exchanger and the top air opening and finally enters thetop of the atrium; and in winter, air at the top of the atrium sequentially passes through the top air opening, the second draught fan, the heat exchanger and the bottom air opening and finally entersthe bottom of the atrium. The invention aims to provide the atrium air conditioning ventilation system based on the heat exchanger and the operation method thereof to solve the problem of an existingatrium air conditioning system that it is impossible to adjust the vertical temperature gradient of building atrium space in both winter and summer. In both winter and summer, the air conditioning ventilation system can make the temperature field of the atrium space vertically uniform.

Description

technical field [0001] The invention belongs to the technical field of building air-conditioning system engineering design. Specifically, it relates to a heat exchanger-based air-conditioning wind system capable of uniformly adjusting the temperature field of a building atrium and an operating method thereof. Background technique [0002] The atrium refers to the courtyard space inside the building. Its biggest feature is to form an "outdoor space" located inside the building. It is a unique form of isolation and integration with the external space in architectural design, or it is a sharing of the internal environment of the building. A way of external environment. In modern public buildings, more and more atriums are used to improve the interior space of buildings, which is one of the contemporary popular architectural space forms. However, due to the high vertical height of the atrium space, the chimney effect is obvious. On the one hand, hot air rises, causing higher ...
