Description

Technical Field

[0001] The utility model relates to an air conditioning system which can provide a variety of air supply temperatures, air supply humidity and air supply pressures, and relates to the technical field of industrial air conditioning systems, in particular to an air conditioning system which can provide a variety of air supply temperatures, air supply humidity and air supply pressures. Background Art

[0002] In most cases at the production site, the production line has only one cooling point, and the process cooling temperature requirements are relatively simple, so one air conditioner can meet the process requirements. Some production lines have multiple cooling points, and multiple cooling points require different air supply temperatures, air supply humidity, and air supply pressures. An air conditioner provides a supply air temperature, air supply humidity, and air supply pressure, which can only meet the requirements of one cooling point, but cannot meet the different process requirements of multiple cooling points. The process requirements can only be met by configuring multiple air conditioners, which increases equipment investment and operating costs.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new air conditioning system that can provide a variety of air supply temperatures, air supply humidity, and air supply pressures, so as to overcome the problems existing in the prior art. Summary of the invention

[0004] According to the above-mentioned prior art, one air conditioner cannot meet the different process requirements of multiple cooling points, and multiple air conditioners need to be configured, which increases the equipment investment and operating costs. An air conditioning system that can provide multiple air supply temperatures, air supply humidity, and air supply pressure is provided. The utility model mainly uses the addition of corresponding valves, mixing chambers, functional sections, fans and their control systems to achieve the purpose of providing multiple air supply temperatures and air supply humidity in one air conditioning unit to meet the cooling needs of multiple cooling points.

[0005] The technical means adopted by the utility model are as follows:

[0006] An air conditioning system capable of providing a variety of air supply temperatures, air supply humidity and air supply pressures comprises: an air conditioning unit, an air conditioning air inlet, an air conditioning air outlet, a main air supply structure and an auxiliary air supply structure;

[0007] Furthermore, the air conditioning unit is provided with an air conditioning inlet for air conditioning intake and an air conditioning outlet for air conditioning exhaust;

[0008] Further, there is at least one air inlet for the air conditioner;

[0009] Further, the air outlet of the air conditioner includes: a main air outlet of the air conditioner and at least one auxiliary air outlet of the air conditioner;

[0010] Further, the main air outlet of the air conditioner is connected to the main air supply structure;

[0011] Furthermore, the auxiliary air outlet of the air conditioner is connected to the auxiliary air supply structure through an air duct.

[0012] Furthermore, the air-conditioning air intake includes but is not limited to one or more of fresh air intake, ambient air intake, process return air intake or combined air intake.

[0013] Furthermore, the main body of the main air supply structure is cooling point A, which is connected to the air outlet of the air conditioner through an air duct.

[0014] Furthermore, the auxiliary air supply structure includes: a valve, a mixing chamber, a fan and a cooling point B;

[0015] Further, the mixing chamber, the fan and the cooling point B are connected in sequence through air ducts;

[0016] Furthermore, the mixing chamber is used to mix gases of different temperatures and humidities, and is connected to the auxiliary air outlet of the air conditioner through an air duct, and a valve is provided on the air duct between the two. The valve is used to adjust the proportion of air volume of the air outlet of the air conditioner in all air sources to control the air temperature of cooling point B; the fan is used to control the wind pressure of cooling point B.

[0017] Furthermore, at least two air inlets are provided on the mixing bin, one for connecting to an air outlet of the air conditioner, and the other for connecting to one of process return air, humidified air and ambient air.

[0018] Furthermore, the auxiliary air supply structure is also provided with an optional functional section;

[0019] Furthermore, the optional functional section is arranged between the mixing chamber and the fan.

[0020] Furthermore, the optional functional sections include but are not limited to one of a surface cooling section, a spraying section or a heating section.

[0021] The working process of the utility model is:

[0022] Take the production line with two cooling points as an example, and take the cooling air supply temperature, humidity and pressure of cooling point A as the basic conditions for air conditioning design. One of the air outlets of the air conditioner is connected to cooling point A through an air duct, and the cooling air is directly delivered to cooling point A. The other air outlet of the air conditioner is connected to the mixing bin.

[0023] Temperature control: When the required air temperature of cooling point B is higher than that of cooling point A, the air source of the other air inlet of the mixing bin can be selected as process return air, ambient air, etc. (the air source temperature is higher than the air conditioning supply air temperature), and the air volume proportion of the air conditioning outlet in the air source is controlled by adjusting the opening of the valve to make the mixed air temperature reach the required process temperature of cooling point B. When the required air temperature of cooling point B is lower than that of cooling point A, the air source of the other air inlet of the mixing bin can be selected as cold east wind (the air source temperature is lower than the air conditioning supply air temperature) or a functional section-surface cooling section can be added to reach the required process temperature of cooling point B.

[0024] Humidity control: The process humidity required for cooling point B can be achieved by controlling the humidity of another air inlet of the mixing bin or adding a functional section - spray section.

[0025] Pressure control: The process air supply pressure is regulated by adjusting the air supply fan pressure of the fan inside the air conditioner and the air supply pressure of the fan between the mixing chamber and the cooling point B.

[0026] Compared with the prior art, the utility model has the following advantages:

[0027] 1. The air conditioning system provided by the utility model can provide a variety of air supply temperatures, air supply humidity, and air supply pressure. When there are three or more cooling points, by adding corresponding valves, mixing chambers, functional sections, fans and their control systems, one set of air conditioning units can provide a variety of air supply temperatures and air supply humidity to meet the cooling needs of multiple cooling points.

[0028] 2. The utility model provides an air conditioning system that can provide a variety of air supply temperatures, air supply humidity, and air supply pressures. Different air supply pressures at multiple air supply points can be achieved by adjusting the air conditioning fan pressure and the fan pressure after the mixing chamber.

[0029] 3. The utility model provides an air conditioning system that can provide a variety of air supply temperatures, air supply humidity, and air supply pressures, thereby reducing the equipment footprint, plant construction costs, and equipment investment costs.

[0030] In summary, the technical solution of the utility model solves the problem in the prior art that one air conditioner cannot meet the different process requirements of multiple cooling points, and multiple air conditioners need to be configured, which increases equipment investment and operating costs.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0039] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0040] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0041] like Figure 1 As shown, the utility model provides an air conditioning system that can provide a variety of air supply temperatures, air supply humidity, and air supply pressures; the sensing system is configured with an air conditioning unit 1 and two cooling points;

[0042] When there are two cooling points, the design outlet temperature of the air conditioning unit 1 is based on one of the process temperature T1 requirements. The air conditioning unit 1 is provided with two outlets. The main outlet 12 of the air conditioning supplies the cooling point A2. The overall outlet temperature of the air conditioning is controlled according to the temperature T1 at the cooling point A2. A mixing bin 4 is provided at the auxiliary outlet 13 of the air conditioning. The mixing bin has two air inlets. The mixing bin inlet A41 is connected to the auxiliary outlet 13 of the air conditioning through an air duct and a valve 3. The air source of the mixing bin inlet B42 is determined according to the temperature T2 and humidity required by the cooling point B7, including but not limited to process return air, humidified air, ambient air, etc. A fan 6 is provided at the outlet of the mixing bin 4 to provide power for the cooling air and regulate the air pressure. The opening of the valve is controlled according to the temperature T2 at the cooling point B7, thereby controlling the air volume proportion of the auxiliary outlet 13 of the air conditioning in the air source so that the mixed air temperature reaches the process temperature required by the cooling point B7. In order to meet the different needs of the cooling point of the production line in different time periods, a functional section can be added between the mixing bin 4 and the fan 6, which includes but is not limited to a heating section, a surface cooling section, a spraying section, etc.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
