It should be understood that the data used in this way can be interchanged where appropriate, so that the implementation of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0052] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0053] As mentioned in the above background technology: the purification air conditioning system is a system that continuously delivers a certain amount of processed air into the clean room to maintain the required temperature, humidity, wind speed, pressure, cleanliness and other parameters in the clean room to eliminate various heat and humidity interferences and dust pollution inside and outside the clean room.

[0054] The purification air conditioning system includes an air supply section, a temperature and humidity processing module, and a cleanliness processing module. The air supply section transports the outside air to the temperature and humidity processing module and the cleanliness processing module. The temperature and humidity processing module and the cleanliness processing module process the air and obtain air with preset temperature, humidity and preset cleanliness, and transport it to the room through the air supply section.

[0055] However, large-space purification air-conditioning systems are used in scenarios where the building layout has a large span and high height, and the ventilation frequency requirements are in accordance with the clean standards of industrial plants. Generally, a large amount of air is required, which leads to high energy consumption for air transportation.

[0056] Therefore, in order to improve or solve the above technical problems, the embodiment of the present application provides a purification air-conditioning system, which provides an air handling unit and a self-purification circulation unit, wherein the air handling unit includes an air intake unit, a temperature and humidity processing module and a cleanliness processing module, the air intake unit is configured to transport the outside air to the temperature and humidity processing module and the cleanliness processing module, the temperature and humidity processing module is configured to process the outside air to obtain air with a preset temperature and humidity, and the cleanliness processing module is configured to process the air with a preset temperature and humidity to obtain fresh air with a preset cleanliness; the self-purification circulation unit includes a self-purification fan The self-purification fan unit is configured to convey the indoor air to the self-purification module, and the self-purification module is configured to process the indoor air to obtain fresh air with a preset cleanliness level. The air volume required for the clean room is within a certain range. By determining the circulating air volume of the air handling unit and the self-purification circulation unit, the required air volume for the clean room can be achieved. Moreover, compared with the air handling unit, the self-purification circulation unit reduces the processing process of the cold, hot and humidity of the air. Therefore, the energy consumption of the self-purification circulation unit is smaller than that of the air handling unit, thereby reducing the overall energy consumption of the purification air conditioning system.

[0057] The technical solutions shown in the present application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

That is, two-thirds of the air volume needs to be processed for temperature, humidity and cleanliness, and one-third of the air cooling only needs to be processed for cleanliness.

[0122] It should be easily understood that “on,” “above,” and “over” in the present disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on something,” but also includes the meaning of “on something” with intervening features or layers therebetween, and “above” or “over” not only includes the meaning of “above” or “over,” but also may include the meaning of “above” or “over something” with no intervening features or layers therebetween (i.e., directly on something).

[0123] In addition, spatially relative terms, such as "below," "below," "beneath," "above," "above," etc., may be used herein for ease of description to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation shown in the figures. The device may have other orientations (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may likewise be interpreted accordingly.

[0124] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
