Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

It should be noted that, in the present invention, unless otherwise explicitly stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. The specific meaning of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art. Furthermore, in the present disclosure, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature therebetween.

As shown in figure 1, little power new trend system in airtight workshop, including setting up the underground air duct 2 in workshop 1 outside, underground air duct 2 passes through air-supply line 3 and workshop 1 intercommunication, and the mouth end of air-supply line 3 that is located workshop 1 is connected with forced draught blower 4, and workshop 2 is equipped with and is provided with air exhauster 5 in air exit and the air exit, and air exhauster 5 is connected with exhaust pipe 6, and the end of exhaust pipe 6 is located workshop 1 outside and sets up upwards and form chimney formula structure.

Preferably, the underground air duct 2 is arranged on the ground in the length direction of the workshop 1 in the manner of being close to the workshop 1, so that the underground air duct 2 can be prevented from occupying the area on the road surface outside the workshop 1.

On the basis, the underground air duct 2 comprises an air duct arranged on the ground and a cover plate 7 arranged on the air duct, through holes are uniformly distributed on the cover plate 7, the cover plate 7 is detachably connected with the air duct, and therefore the air duct can be cleaned conveniently. It will be appreciated by those skilled in the art that the wind channel can actually receive a certain amount of rainwater and function as a daily drain, and it is only necessary to provide a port at one end of the underground wind channel 2 to guide the rainwater to drain. However, in some environments with high requirements for air quality of workshops, structures such as baffles can be arranged above the underground air ducts 2 according to needs to prevent rainwater or sewage from entering.

Wherein, the filter screen 8 that is used for preventing that filth impurity from falling into in the secret wind ditch 2 is installed to the bottom surface of apron 7 to guarantee the clean environment in the secret wind ditch 2, thereby make in 2 interior new trend effects when utilizing the ventilation of secret wind ditch 2 in the workshop better.

In addition, in the embodiment, the blower 4 is located at the bottom of the workshop 1, and the exhaust outlet is located at the top of the side wall of the workshop 1, so that the chimney effect can be further improved, and the convection phenomenon formed by airflow in the workshop 1 can be enhanced.

The operating principle of the micro-power fresh air system for the closed workshop provided by the embodiment is based on two aspects, on one hand, the temperature in the outdoor underground air duct 2 is usually lower than that in the indoor workshop 1, and particularly, under the condition of hot summer, a certain temperature difference is formed between the temperature in the underground air duct 2 and the temperature in the workshop 1, so that the gravity pressure difference is formed due to different indoor and outdoor air temperatures, a micro negative pressure state is formed in the workshop 1, and power is provided for low-temperature air to enter the workshop 1; on the other hand, the chimney effect strengthens the phenomenon of air convection, so that even if the temperature difference is not large and the formed negative pressure is small micro negative pressure, the airflow in the underground air duct 2 can enter the workshop 1 and be discharged from the exhaust pipe 6, thereby forming the ventilation effect.

Of course, it will be appreciated by those skilled in the art that this is mainly aimed at the situation where a relatively significant indoor-outdoor temperature difference is formed between the underground air duct 2 and the plant 1 in a hot condition such as summer, so that the ventilation effect of the interior can be enhanced only by turning on the blower 4 and the exhaust fan 5 at regular intervals, which can reduce the energy consumption to a great extent compared with the ventilation in 24 hours without interruption. In the case of low outdoor temperature and humidity, ventilation can be maintained by independently activating the exhaust fan 5, and if the enhancement effect is required, the blower 4 can be simultaneously turned on.

The micropower fresh air system for the closed workshop provided by the embodiment utilizes the characteristics that trench wind is warm in winter and cool in summer, so that the ventilation effect can be achieved only by a little power in sultry summer, for example, under the condition of extremely hot weather, in a 18000 cubic meter closed workshop, only a 0.37kW blower 4 and a 0.55kW exhaust fan 5 need to be arranged, the ventilation can be actively started once every 8 hours, the blower 4 and the exhaust fan 5 do not need to be started under the general conditions of other time, and the energy consumption is greatly saved.

In order to make the skilled person more easily understand the improvement of the present invention compared with the prior art, some drawings and descriptions of the present invention have been simplified, and the above embodiment is the preferred implementation of the present invention, besides, the present invention can be implemented in other ways, and any obvious replacement is within the protection scope of the present invention without departing from the concept of the present invention.
