Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to a combined air conditioning unit. Background Art

[0002] In modern building automation air conditioning systems, modular air conditioning units are widely used due to their modular design, flexible configuration, and high energy efficiency, especially in places with high-level fire protection requirements, such as data centers, high-rise buildings, chemical plants, etc., which put forward more stringent standards for the safety of air conditioning systems. In view of the high sensitivity of such places to fire hazards, modular air conditioning units are often constructed with materials with good fire resistance, such as using Class A non-combustible materials - rock wool as the internal filling of the box.

[0003] However, as an inorganic fiber insulation material, although rock wool board has excellent fireproof performance, due to its inherent physical properties, such as lack of self-adhesion and loose structure, it may not provide sufficient mechanical strength to firmly support and fix heavy components such as fans that vibrate during operation when used for assembly inside air conditioner boxes. During transportation, the risk of component movement under this loose structure may be aggravated due to road bumps and handling operations; and under long-term operation, the continuous vibration generated by fans and other rotating parts may easily cause the rock wool filling part to loosen, thereby affecting the stability and service life of the air conditioning system.

[0055] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0056] The utility model provides an embodiment of a combined air-conditioning unit. The combined air-conditioning unit is one of the most important equipment for air treatment. It does not have a cold or heat source itself, but uses cold or hot water or steam as a medium to complete the functions of filtering, purifying, heating, cooling, humidifying, dehumidifying, silencing, and fresh air treatment of the air.

[0057] Combined air conditioning unit is a customized air handling equipment, which is the core part of the air conditioning system composed of multiple independent functional sections installed according to a specific air handling process. These functional sections can be flexibly matched according to different environmental requirements and process requirements to meet the air conditioning needs of different occasions.

[0058] The basic structure of a combined air-conditioning unit usually includes but is not limited to the following functional sections: primary filtration section, medium filtration section, surface cooling section, heating section, humidification section and fan section.

[0059] Fresh air enters the air conditioning unit and mixes with the return air from the room in the mixing section. The mixed air passes through the primary filter section to filter out dust and debris, and then passes through the medium filter section for secondary filtration to filter out smaller dust and debris. Then, the air is cooled or heated through the surface cooling section or heating section to reach the required temperature point, and then humidified through the humidification section to the humidity required by the system, that is, to reach the specified air supply state point, and finally the treated air is sent into the room through the fan section.

[0060] Specifically, the primary filter section, the medium filter section, the surface cooling section, the heating section, the humidification section and the fan section are all arranged in the box.

[0061] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a combined air-conditioning unit.
