Evaporative cooling air conditioning system based on carbon dioxide monitoring and cooling quantity cascade utilization

Abstract

The invention discloses an evaporative cooling air conditioning system based on carbon dioxide monitoring and cooling quantity cascade utilization. The system is composed of an evaporative cooling air conditioning unit, a carbon dioxide monitoring device, an air feeding pipe and an air returning pipe, wherein air is fed on the upper portion and air returns on the lower portion, outdoor air is processed by the evaporative cooling air conditioning unit to reach the air supplying state point and fed into a room by an air feeding fan so that waste heat and excess moisture in the room can be absorbed, and the temperature and humidity requirement in the room can be met; the carbon dioxide monitoring device is arranged in the room, the carbon dioxide monitoring device is in linkage with a new air returning valve through a control cabinet, and the ratio of new air to return air is automatically adjusted; low-temperature secondary air of an indirect evaporative cooler is exhausted to a roof through a secondary air exhaust pipe, a low-temperature air lake is formed on the roof, and therefore cooling loads formed by heat transfer of the roof can be lowered. According to the evaporative cooling air conditioning system, not only can good indoor air quality be guaranteed, but also energy can be fully utilized, and the system has the advantages that energy is saved, and the system is environmentally friendly and economical.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and in particular relates to an evaporative cooling air-conditioning system based on carbon dioxide monitoring and cooling cascade utilization. Background technique [0002] In recent years, with the development of the economy, environmental problems and energy consumption problems have become increasingly prominent. At the same time, people's requirements for indoor air quality are also getting higher and higher. In densely populated places such as classrooms and meeting rooms, as well as some industrial production workshops, the concentration of carbon dioxide is relatively high. If a fresh air DC air-conditioning system is used, it will consume a lot of energy and cause huge operating costs. So designing an air-conditioning system that not only saves energy but also can monitor the indoor carbon dioxide concentration in real time must be favored by people. [0003] ...
