[0033] To further illustrate the technical means and effectiveness of the present invention in achieving the intended objectives of the embodiments, the following, in conjunction with the accompanying drawings and preferred embodiments, provides a detailed description of the specific implementation, structure, features, and effectiveness of the air conditioning equipment for the environmental protection system according to the embodiments of the present invention. In the following description, different references to "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0034] Figure 1 For an embodiment of the air conditioning equipment of the environmental protection system provided in this embodiment, please refer to Figure 1 The air conditioning equipment of the environmental protection system proposed in one embodiment of this embodiment includes:

[0035] A refrigeration chamber 10, wherein the refrigeration chamber has an air inlet and an air outlet;

[0036] The refrigeration device includes: a compressor, a condenser 20, an expansion valve and an evaporator. The compressor inhales the low-pressure working medium vapor from the evaporator, increases the pressure of the working medium vapor and then sends it to the condenser 20. In the condenser 20, it condenses into a high-pressure liquid. After expanding through the expansion valve, it becomes a low-pressure liquid. After that, it is sent to the evaporator, absorbs heat and evaporates in the evaporator to become a low-pressure vapor.

[0037] The evaporator is arranged in the refrigeration chamber 10;

[0038] The condenser 20 can be expanded and retracted on the outer wall of the refrigeration chamber 10 .

[0039] In the technical solution provided by this embodiment, the condenser can be deployed on the outer wall of the refrigeration chamber during operation of the air conditioning system to dissipate heat from the condenser during refrigeration operation. The evaporator of the air conditioning system is located within the refrigeration chamber. By connecting the air outlet of the refrigeration chamber to the protective tent, the cooling energy emitted by the evaporator within the refrigeration chamber can be transferred to the tent. When cooling is not required, the condenser can be retracted to the outer wall of the refrigeration chamber. The air conditioning system provided by this embodiment has an integrated structure, can be easily installed in a safety isolation tent, and is easy to transport.

[0040] In a specific implementation, the refrigeration chamber can be a positive pressure chamber, which can be a sealed or unsealed chamber. By injecting positive pressure gas into the positive pressure chamber, the air pressure within the positive pressure chamber is maintained in a positive pressure environment. This prevents external contaminants from entering the positive pressure chamber and contaminating the evaporator within the positive pressure chamber. In practice, the compressor and expansion valve are disposed within the refrigeration chamber, thereby preventing contamination of the compressor and expansion valve within the positive pressure chamber.

[0041] In some embodiments, the device for introducing positive pressure gas can be a purification ventilation device, the purification air outlet of the purification ventilation device is connected to the air inlet of the positive pressure cabin, and the air outlet of the positive pressure cabin can be connected to the main room of the isolation tent that provides a clean space for personnel, so that the cold energy generated by the refrigeration device can be delivered into the main room.

[0042] The purification ventilation device includes: an air inlet valve, a ventilation fan, a coarse filter, a filter-absorber, an air volume meter, and an air outlet valve, which are connected in sequence. The air inlet valve, the ventilation fan, the coarse filter, the filter-absorber, the air volume meter, and the air outlet valve are disposed outside the positive pressure cabin, and the air outlet valve is disposed at the purification air outlet. When the purification ventilation device is turned on, the air inlet valve, the ventilation fan, the air outlet valve, and the internal circulation fan of the purification ventilation device are opened, and external air flows through the air inlet valve, the ventilation fan, the coarse filter, the filter-absorber, the air volume meter, and the air outlet valve in sequence, and enters the positive pressure cabin.

[0043] The external polluted air is initially filtered by a coarse filter to remove larger particles. The filter absorber then further removes pollutants, creating fresh, clean air that is then delivered to the positive pressure cabin. Finally, the fresh, clean air in the positive pressure cabin is driven by an internal circulation fan and delivered to the users in the isolation tent. The internal circulation fan can be installed in the positive pressure cabin, but is not limited to this location.

[0044] In some embodiments, the device for introducing positive pressure gas can be a clean ventilation device, the clean air outlet of the clean ventilation device is connected to the air inlet of the positive pressure cabin, and the air outlet of the positive pressure cabin can be connected to the main room of the isolation tent that provides a clean space for personnel, so that the cold energy generated by the refrigeration device can be delivered into the main room.

[0045] The clean ventilation device includes: an air inlet valve, a ventilation fan, a coarse filter, and an air outlet valve, which are sequentially connected. The air outlet valve of the clean ventilation device is located at the clean air outlet of the clean ventilation device. The clean ventilation device can be installed outside the positive pressure cabin. When the clean ventilation device is turned on, the air inlet valve, ventilation fan, air outlet valve, and internal circulation fan of the clean ventilation device are activated, and external air flows through the air inlet valve, ventilation fan, coarse filter, and air outlet valve of the clean ventilation device in sequence, and enters the positive pressure cabin.

[0046] The external polluted air is initially filtered by a coarse filter to remove larger particles and is then sent into the positive pressure cabin. Finally, the fresh, clean air in the positive pressure cabin is driven by an internal circulation fan and sent to the users in the isolation tent for use.

[0047] In addition, the air conditioner of the environmental protection system described in the above embodiment may also include: a heating device, the heating output part of the heating device is arranged in the positive pressure cabin, and when it is necessary to provide heat to the isolation tent, the refrigeration device can be turned off and the heating device can be turned on. Driven by the internal circulation fan, the heat is sent to the users in the isolation tent for use.

[0048] When the condenser 20 is deployed and retracted relative to the outer wall of the refrigeration chamber 10, the compressor and the condenser 20 communicate with the working medium via a first pipe, the condenser 20 and the expansion valve communicate with the working medium via a second pipe, the expansion valve and the evaporator communicate with the working medium via a third pipe, and the evaporator and the compressor communicate with the working medium via a fourth pipe. The first and second pipes are hoses 30. Since the first and second pipes are hoses 30, which may be rubber hoses, etc., the condenser 20 can be deployed and retracted relatively freely relative to the refrigeration chamber 10.

[0049] In order to realize the expansion and contraction of the condenser on the outer wall of the refrigeration chamber, different structural forms can be selected.

[0050] Taking the example of folding the condenser 20 to expand and contract on the outer wall of the refrigeration chamber 10, the condenser 20 can be foldably arranged on the outer wall of the positive pressure chamber 10. The outer wall of the refrigeration chamber 10 is provided with a first limiting portion 11; the condenser 20 is provided with a second limiting portion 21; the top of the condenser 20 and the top of the side wall of one side of the positive pressure chamber 10 are rotatably connected; when the condenser 20 is rotated and expanded from the side wall of the refrigeration chamber 10 to a preset angle, the first limiting portion 21 and the second limiting portion 22 can be locked with each other to limit the condenser 20 and the side wall of the refrigeration chamber 10 to maintain the preset angle, which can be between 30-90 degrees. After limiting the condenser 20 and the side wall of the refrigeration chamber 10 to maintain the preset angle, the heat dissipation of the condenser 20 can be facilitated. The interlocking method between the first limiting portion 21 and the second limiting portion 22 can be pin interlocking, chain interlocking, etc. It is easy to understand that the interlocking structure can adopt any method in the existing technology, which is not listed in this embodiment.

[0051] In addition to folding the condenser to expand and contract against the outer wall of the refrigeration chamber, the condenser can also be slidably mounted against the outer wall of the refrigeration chamber. The outer wall of the refrigeration chamber can be provided with a slide rail, with the condenser slidably connected to the slide rail. When the condenser slides to a first position relative to the outer wall of the refrigeration chamber, the condenser is entirely covered by the outer wall of the refrigeration chamber. The condenser's first locking member can be locked with the refrigeration chamber's second locking member to restrict the relative position of the condenser and the refrigeration chamber. When the condenser slides to a second position relative to the outer wall of the refrigeration chamber, at least a portion of the condenser is separated from the outer wall of the refrigeration chamber for heat dissipation. The condenser's first locking member can be locked with the refrigeration chamber's third locking member to restrict the relative position of the condenser and the refrigeration chamber. The interlocking mechanism between the first and second locking members, and between the first and third locking members, can employ pin interlocking, chain interlocking, and the like. It will be readily understood that any interlocking mechanism known in the art can be employed and will not be further detailed in this embodiment.

[0052] In the technical solution provided by this embodiment, the condenser can be deployed on the outer wall of the refrigeration chamber during operation of the air conditioning system to dissipate heat from the condenser during refrigeration operation. The evaporator of the air conditioning system is located within the refrigeration chamber. By connecting the air outlet of the refrigeration chamber to the protective tent, the cooling energy emitted by the evaporator within the refrigeration chamber can be transferred to the tent. When cooling is not required, the condenser can be retracted to the outer wall of the refrigeration chamber. The air conditioning system provided by this embodiment has an integrated structure, can be easily installed in a safety isolation tent, and is easy to transport.
