Problems solved by technology

In addition, due to the defects of the traditional air conditioning system itself, unreasonable indoor air flow organization or insufficient fresh air volume, the pollutants (gas) generated indoors cannot be discharged in a timely and effective manner, resulting in a decline in indoor air quality and affecting the health of indoor personnel. This effect is particularly obvious in the building, resulting in air-conditioning syndrome, etc., and such problems are also being paid attention to by the society.

Embodiment 1

[0027] Embodiment 1: From the perspective of human comfort, the following factors should be considered during the design of the wave-shaped air supply system:

[0028] (1) Pulsation frequency (the pulsation frequency of the wave-type air supply system should fall outside the uncomfortable zone frequency of 0.3~0.5HZ), if the frequency is too large or too small, it will affect the pulsation amplitude of the wind speed, and the comfort of the human body to the airflow will decrease;

[0029] (2) The average velocity of the air outlet of the pulsation device;

[0030] On the other hand, when the wave-type air supply system is applied to actual air-conditioning projects, the following principles must also be considered:

[0031] (1) The structure of the pulsation device is as simple as possible, with few moving parts, low cost and easy maintenance;

[0032] (2) The resistance of the pulsation device should be small and the noise should be low;

[0033] (3) The aerodynamic perfor...

Embodiment 2

[0036] Embodiment 2: Others are the same as Embodiment 1. When the distance between the inner and outer deflectors is set to 1cm and the rotating speed of the micro-motor is set to 5rpm, the pulsating airflow with a pulsating frequency of 0.083HZ can be periodically provided to the work area;

Embodiment 3

[0037] Embodiment 3: Others are the same as Embodiment 1, when the distance between the inner and outer deflectors is set to 1cm, and the rotating speed of the micro-motor is set to 8rpm, the pulsating airflow with a pulsating frequency of 0.133HZ can be periodically provided to the work area;

Abstract

The invention discloses a wave-type air supply system comprising a blast pipe (4) and an air pipe (14); the blast pipe is connected with a branch blast pipe (5); an air supply valve (6) is arranged atthe branch blast pipe (6). The wave-type air supply system is characterized in that the branch blast pipe (5) is connected with a wave-type air supply device (7) which can pulsate and thus supply air. The wave-type air supply system has the advantages that the air supply system can produce pulsating airflow with changing intensity; thus people feel pleasantly cool instead of feeling boring in a stable airflow; the air supply system can ensure a equivalent temperature and at the same time save energy.

Description

technical field [0001] The invention relates to an air supply system, in particular to a wave type air supply system. The invention is suitable for indoor air supply. The wave type air supply device in the present invention is also suitable for other ventilation systems. Background technique [0002] The comfort of air-conditioning is the result of the comprehensive influence of thermal comfort, oxygen content, odor, noise and air pollution. It is related to living habits, physical fitness, and labor intensity. The comfort of the original air conditioning system only considers the influence of changes in wind speed, temperature and humidity on the comfort of the human body under the condition of stable air supply, and pursues a uniform temperature and air supply speed indoors to meet the comfort requirements of indoor personnel. In actual operation, the comfort requirements of all personnel cannot be well satisfied. Practice and research in recent years have found that: ...
