Building model indoor natural ventilation testing device and testing method

Abstract

The invention belongs to the technical field of building ventilation, and discloses a building model indoor natural ventilation testing device and a testing method. The testing device comprises a temperature detection module, a humidity detection module, a carbon dioxide detection module, a central control module, a ventilation volume calculation module, a ventilation regulation module, a data storage module, and a display module. The invention also discloses a testing method. Through the ventilation volume calculation module, the total indoor fresh air volume is calculated, and the indoor ventilation volume can be known more intuitively by a user; through the ventilation regulation module, excellent indoor ventilation effects are improved; and the indoor area is finely divided, each smalldivided area is subjected to information acquisition and environmental regulation, the pertinence of environmental regulation in each small area is improved, and a good indoor environment is thus ensured.

Description

technical field [0001] The invention belongs to the technical field of building ventilation, and in particular relates to a test device and a test method for natural ventilation in a building model room. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Architecture is the general term for buildings and structures, and it is an artificial environment created by people using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts, and aesthetic principles to meet the needs of social life. Construction refers to the process of constructing buildings or developing infrastructure. Generally speaking, each construction project will be coordinated by project managers and architects, and will be organized by contractors, sub-contractors (Sub-contractors), engineering consultants, builders, quantity surveyors, structural engineers and other professionals (...

AI Technical Summary

Problems solved by technology

[0005] Existing buildings cannot intuitively obtain ventilation data, which affects users' understanding of indoor ventilation; at the same time, the existing indoor exhaust system has low intelligence and cannot ventilate each area in a targeted manner, which cannot guarantee the comprehensiveness of the ventilation effect

[0006] The existing phase noise measurement methods all use special hardware circuits to extract the phase information of the signal source under test, and use this to analyze the SSB phase noise of the signal source under test, so that the extraction performance of the phase extraction circuit is largely Determines the performance of the phase noise measurement, and the frequency response of the phase extraction circuit will also affect the measurement results

[0007] In the prior art, the problem of inaccurate calculation results in the calculation of ventilation volume parameter values
