Air supply device

Abstract

The invention provides an air supply device. The air supply device comprises a shell, a partition plate, a flow equalizing plate and an the adjustable baffle, wherein a cavity is formed in the shell, the partition plate divides the cavity of the shell into an upper cavity body and a lower cavity body, the flow equalizing plate is vertically arranged in the upper cavity and divides the upper cavity into an air inlet cavity and a static pressure cavity, a first air inlet communicating with the air inlet cavity is formed in the shell, the vertical height of the adjustable baffle is smaller than that of the lower cavity body, the adjustable baffle divides the lower cavity body into an induction cavity and a heat exchange cavity, a first induction air port is formed by the adjustable baffle and the top of the lower cavity body, a heat exchanger is arranged in the heat exchange cavity, a second air inlet communicating with the heat exchange cavity is formed in the shell, and a first air outlet is formed in one side, far away from the upper cavity body, of the induction cavity. According to th eair supply device, the partition plate is provided with a ventilation opening communicating with the static pressure cavity and the induction cavity, indoor return air is prevented from passing through an air outlet and then being conveyed to the first air inlet through an air pipe to enter the air supply device, and energy consumption of the indoor return air in the conveying process is reduced.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air supply device. Background technique [0002] With the development of science and technology, more and more work can be done indoors. Modern people spend 80% to 90% of their time indoors living and working in the indoor environment. Therefore, the quality of the indoor environment directly affects people's health. To maintain good health, an effective way to improve indoor air quality is to improve indoor air circulation, accelerate the discharge of indoor polluted air, and accelerate the injection of outdoor fresh air. [0003] In the existing air supply device, the indoor return air needs to be discharged from the room through a separate air outlet, enter the air handling unit and mix with the fresh air, and then be sent to the terminal air supply device. In the actual use process, the static pressure box needs to be processed at the same time Fresh air and in...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an air supply device, which solves the problem that the air supply device in the prior art needs to add a static pressure box when dealing with fresh air and indoor return air, and the size of the static pressure box is generally Larger, it is inconvenient to install in office buildings. On the other hand, the air volume of the existing system cannot be changed in real time during the return air process, so the adjustment of the fresh air ratio can only be realized by adjusting the fresh air volume, which increases the energy of the overall system. Consumption, reducing the utilization rate of return air
