Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example 1:

[0029] In this embodiment, a phase change energy storage floor, such as... Figures 1 to 3 As shown, it includes a floor body 1 and a phase change energy storage module 2. Specifically, the phase change energy storage module 2 is installed on the bottom side of the floor body 1. The phase change energy storage module 2 has a hollow structure and is filled with a solid-liquid phase change cold storage material. The solid-liquid phase change cold storage material can exchange heat with the outside through solid-liquid phase change to achieve the function of cold storage and cold release. It is preferably a straight-chain alkane or an inorganic salt.

[0030] When the air conditioner in the machine room is running, the solid-liquid phase change cold storage material in the phase change energy storage module 2 can exchange heat with the cold air to store cold. When the air conditioner is on standby or fails to operate, the phase change energy storage module 2 can release the stored cold to provide emergency cooling or supplement indoor cooling capacity, delay the indoor air temperature rise speed, thereby prolonging the air conditioner start-stop interval, reducing the air conditioner start-stop frequency, improving the reliability and service life of the air conditioner, and making the utility model more practical.

[0031] In the embodiment, as shown in Figure 1 The number of the phase change energy storage module 2 is multiple, and the multiple phase change energy storage modules 2 are arranged in parallel at the bottom of the floor body 1 to improve the heat exchange efficiency and the cold storage capacity.

[0032] In the embodiment, as shown in Figure 2 and Figure 3 Further, two guide rails 3 are arranged in parallel and at intervals at both ends of the bottom of the floor body 1, and both ends of the multiple phase change energy storage modules 2 are slidably connected in the two guide rails 3. Both ends of the guide rail 3 are provided with a limiting locking piece 4. During installation, the phase change energy storage module 2 is slid into the track groove of the guide rail 3 from the side end of the guide rail 3, and the multiple phase change energy storage modules 2 are closely fitted. The two ends of the guide rail 3 bind all the phase change energy storage modules 2 from both ends through the limiting locking piece 4, preventing the phase change energy storage modules 2 from separating from the guide rail 3. The limiting locking piece 4 can be a screw or a bolt.

[0033] Further, as shown in Figure 3 The side of the guide rail 3 away from the phase change energy storage module 2 is provided with a support 5, the support 5 is fixed to the bottom side of the floor body 1 through a first fixing piece 6, and the guide rail 3 is fixed to the support 5 through a second fixing piece 7. The first fixing piece 6 and the second fixing piece 7 are screws or bolts. The support 5 is used to fix the guide rail 3, so that a gap is formed between the phase change energy storage module 2 and the floor body 1, the phase change energy storage module 2 is suspended below the floor body 1, and the contact area of the phase change energy storage module 2 with air is increased.

[0034] In the embodiment, as shown in Figure 3 Each phase change energy storage module 2 is provided with a breather valve 8 at one end of the top side. The breather valve 8 communicates with the inside of the phase change energy storage module 2. The breather valve 8 leads to the gap formed between the phase change energy storage module 2 and the floor body 1. The breather valve 8 is used to balance the pressure between the space of the solid-liquid phase change material in the phase change energy storage module 2 and the external environment, preventing the phase change material from changing in volume and causing the phase change energy storage module 2 to rupture or deform due to overpressure or underpressure when the solid-liquid phase change material changes phase.

[0035] Further, as shown in Figure 2 and Figure 3As shown, the bottom side of the phase change energy storage module 2 is uniformly provided with a plurality of protruding ridges 9 along the length direction. The protruding ridges 9 increase the surface area of ​​the phase change energy storage module 2, thereby expanding the heat exchange area of ​​the phase change energy storage module 2 and turbulentizing the air convection on the surface of the phase change energy storage module 2 to enhance the heat exchange capacity.

[0036] In this embodiment, the floor body 1 is preferably an anti-static floor, which has good conductivity and can quickly conduct static electricity to the grounding system to ensure that static electricity is effectively eliminated.

[0037] Example 2:

[0038] In this embodiment, an auxiliary cooling source system, such as Figure 4 As shown, the system includes an exhaust fan 10, an exhaust fan 11, a support member 12, and a phase change energy storage floor. Specifically, multiple phase change energy storage floors are erected on the floor of the machine room via the support member 12 to form a floor surface. An overhead space 13 is formed between the floor surface and the ground via the support member 12. The overhead space 13 allows indoor air to circulate. The floor surface has an air inlet and an air outlet at both ends that communicate with the overhead space 13. The exhaust fan 10 and the exhaust fan 11 are respectively located at the air inlet and the air outlet. The exhaust fan 10 and the exhaust fan 11, one in and one out, enable air circulation between the overhead space 13 below the floor surface and the machine room space above.

[0039] By adopting this structure, the indoor air is continuously supplied to the phase change energy storage floor through the exhaust fan 10 and the supply fan 11 for heat exchange to store or release cold energy. This achieves the effects of storing cold energy when the air conditioner is running, supplementing cold energy when the air conditioner is on standby, and providing emergency cooling when the air conditioner fails. This solves the problem of frequent start-stop of the air conditioner in the computer room and the problem of low-cost and efficient emergency cooling under the condition of sudden air conditioner failure or power outage. It also extends the time interval between air conditioner start-stop and improves the lifespan and operational reliability of the air conditioner.

[0040] In this embodiment, a UPS power supply 14 is also included. The exhaust fan 10 and the blower 11 are both electrically connected to the UPS power supply 14, which can provide uninterrupted power to the exhaust fan 10 and the blower 11, so that the air in the computer room can be continuously circulated.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
