[0049] The invention provides an evaporator component for reducing air conditioning energy consumption, a machine room air conditioner and a control method thereof.

[0050] Combine the following Figures 1 to 13 The technical solution provided by the present invention is described in more detail.

[0051] The present invention provides an evaporator assembly, comprising:

[0052] A heat exchanger body 200 and an evaporator structure 300, wherein the evaporator structure 300 includes at least one evaporator body 330, and the heat exchanger body 200 is movably arranged on the evaporator structure 300 so that the heat exchanger body 200 is placed on the air outlet 120, and the incoming air passes through the heat exchanger body 200 for heat exchange;

[0053] Alternatively, the heat exchanger body 200 and the at least one evaporator body 330 are disposed on the air outlet 120 , and the incoming air exchanges heat through the heat exchanger body 200 and the at least one evaporator body 330 .

[0054] The evaporator assembly provided by the present invention includes a heat exchanger body 200 and an evaporator structure 300. The heat exchanger body 200 is movably arranged on the evaporator structure 300, so that the heat exchanger body 200 can be placed on the air outlet 120, and the incoming air passes through the heat exchanger body 200 for heat exchange; or, the heat exchanger body 200 and at least one evaporator body 330 are arranged on the air outlet 120, and the incoming air passes through the heat exchanger body 200 and at least one evaporator body 330 for heat exchange, so that the computer room air conditioner can select the heat exchanger body 200 for heat exchange or select the heat exchanger body 200 and at least one evaporator body 330 for heat exchange at the same time, and can select an appropriate number of evaporator bodies 330 according to actual needs, so as to reduce the number of working evaporators under low load conditions, thereby reducing the cooling capacity of the whole machine and reducing power consumption; avoiding the situation that the room temperature can only be maintained by frequently starting and stopping the compressor of the whole machine when the load is low, thereby reducing the energy consumption of the air conditioner.

[0055] In addition, the heat exchanger body 200 can be movably arranged on the evaporator structure 300, forming an adjustable layout of the heat exchanger body 200 and the evaporator body 330, which greatly reduces the space occupied by the evaporator assembly, makes the structure of the evaporator assembly more compact, and reduces the area occupied by the computer room air conditioner.

[0056] It can be understood that the evaporator assembly provided by the present invention is arranged on the air outlet 120, and the heat exchanger body 200 can cover the air outlet 120. When heat is exchanged through the heat exchanger body 200, cooling or heating can be achieved; and when the load is high, the heat exchanger body 200 can be moved on the evaporator structure 300 so that the heat exchanger body 200 and at least one evaporator body 330 cover the air outlet 120 at the same time. At this time, the incoming air can be simultaneously exchanged with the heat exchanger body 200 and at least one evaporator body 330 to increase the heat exchange amount and the heat exchange area, thereby meeting the high load requirement; and when the load is low, the heat exchanger body 200 can be moved on the evaporator structure 300 so that the heat exchanger body 200 can be cooled or heated alone, or the number of evaporator bodies 330 can be reduced, thereby reducing the heat exchange amount and the heat exchange area, thereby meeting the low load requirement.

[0057] It should be noted that, in some embodiments, the heat exchanger body 200 is connected to the first cooling unit, and at least one of the evaporator bodies 330 is connected to the second cooling unit. The first cooling unit is used to provide refrigerant to the heat exchanger body 200, and the second cooling unit is used to provide refrigerant to at least one of the evaporator bodies 330. When the load is high, the first cooling unit and the second cooling unit work at the same time. When the second cooling unit is working, the number of evaporator bodies 330 can be selected as needed; when the load is low and the room temperature needs to be maintained, only the first cooling unit is required to work, and the room temperature is maintained through heat exchange in the heat exchanger body 200, which greatly reduces the internal consumption of the air conditioner.

[0058] In some embodiments of the present invention, the heat exchanger body 200 is slidably disposed on the evaporator structure 300 via a sliding assembly 340. The heat exchanger body 200 is slidably disposed on the evaporator structure 300, which can more quickly and efficiently complete the switching between the heat exchanger body 200 and the evaporator body 330.

[0059] In some embodiments of the present invention, the sliding assembly 340 includes a sliding drive structure, a sliding pulley 344 and a sliding guide rail 345, the sliding guide rail 345 is arranged on the evaporator structure 300, the sliding pulley 344 is arranged on the heat exchanger body 200, and the sliding drive structure is used to drive the heat exchanger body 200 to slide on the evaporator structure 300 along the sliding guide rail 345.

[0060] In some of the above-mentioned embodiments of the present invention, the sliding assembly 340 includes a sliding pulley 344 and a sliding guide rail 345, the sliding guide rail 345 is arranged on the evaporator structure 300, and the sliding pulley 344 is arranged on the heat exchanger body 200. The sliding drive structure drives the sliding pulley 344 on the heat exchanger body 200 to slide along the sliding guide rail 345, so as to adjust the position of the heat exchanger body 200 on the evaporator structure 300. Through the cooperation of the sliding pulley 344 and the sliding guide rail 345, the structure is simple and the sliding is smooth, which is convenient for efficiently and quickly completing the reciprocating movement of the heat exchanger body 200.

[0061] In some embodiments of the present invention, the sliding drive structure includes a driving motor 341, a winding pulley 342 and a wire rope 343, the first end of the wire rope 343 is connected to the heat exchanger body 200, and the second end of the wire rope 343 passes through the winding pulley 342 and is connected to the driving motor 341.

[0062] In some of the above embodiments of the present invention, the sliding drive structure includes a drive motor 341, a winding pulley 342 and a steel wire rope 343. The drive motor 341 drives the heat exchanger body 200 to move through the steel wire rope 343, so that the heat exchanger body 200 slides on the evaporator structure 300.

[0063] In some embodiments of the present invention, sealing baffles 230 are provided on both sides of the heat exchanger body 200, an elastic member 240 is provided between the sealing baffles 230 and the heat exchanger body 200, and the steel wire rope 343 is connected between the two sealing baffles 230 of the heat exchanger body 200.

When the steel wire pull rope 343 pulls the sealing baffle 230 under the drive of the driving motor 341, the sealing baffle 230 will press the elastic member 240 to compress the elastic member 240, thereby reducing the distance between the two sealing baffles 230, thereby providing a moving gap for the movement of the heat exchanger body 200 and reducing the friction between the two sides of the heat exchanger body 200 and the evaporator structure 300. When the steel wire rope 343 is not driven by the driving motor 341, the two sealing baffles 230 will move to both sides under the elastic force of the elastic member 240, thereby ensuring a better sealing structure between the heat exchanger body 200 and the evaporator structure 300 to avoid air leakage and ensure that all the incoming air can be discharged from the air outlet 120 after heat exchange through the heat exchanger body 200 or the evaporator body 330.

[0065] It can be understood that the sealing baffle 230 is a U-shaped structure, and the sealing baffle 230 is sleeved on both sides of the heat exchanger body 200, and an elastic member 240 is provided between the sealing baffle 230 and the side wall of the heat exchanger body 200, and the elastic member 240 is preferably a spring, and the elasticity is good enough to drive the sealing baffle 230 to a position away from the heat exchanger body 200. When the rope pulls the sealing baffle 230, the sealing baffle 230 will move toward the heat exchanger body 200 and get close to the heat exchanger body 200.

[0068] It is understandable that when there are multiple heat exchanger split bodies 210, the heat exchanger body 200 can move between the multiple heat exchanger bodies 200, and the locking structures 346 need to be provided in multiple numbers to ensure that the heat exchanger body 200 can be positioned on the evaporator structure 300.

[0069] In some embodiments of the present invention, the heat exchanger body 200 includes two heat exchanger split bodies 210 , and the first ends of the two heat exchanger split bodies 210 are hinged; and the second ends of the two heat exchanger split bodies 210 are connected to the evaporator structure 300 .

When the heat exchanger body 200 alone or the heat exchanger body 200 and at least the evaporator body 330 are arranged on the air outlet 120, the V-shaped structure can increase the heat exchange area and the heat exchange amount, thereby meeting the low load or high load cooling / heating requirements.

[0071] In some embodiments of the present invention, the evaporator structure 300 includes two frame bodies 310 and two frame sealing plates 320;

[0072] The two frame bodies 310 are arranged in a V-shaped structure, and the two frame sealing plates 320 are sealed on the front and rear sides of the two frame bodies 310; the second ends of the two heat exchanger split bodies 210 are movably arranged between the two frame sealing plates 320;

[0073] At least one of the evaporator bodies 330 includes an evaporator split body 331 disposed on two of the frame bodies 310 .

[0074] In some of the above-mentioned embodiments of the present invention, the evaporator structure 300 includes two frame bodies 310 and two frame sealing plates 320; the two frame bodies 310 are arranged in a V-shaped structure, and the two frame sealing plates 320 are sealed on the front and rear sides of the two frame bodies 310 to form a closed cross-section of the evaporator structure 300 with a triangular structure, and the second ends of the two heat exchanger splits 210 can be movably arranged between the two frame sealing plates 320, and by driving the two heat exchanger splits 210 to move between the two frame sealing plates 320, the two heat exchanger splits 210 or the two heat exchanger splits 210 and at least two evaporator splits 331 can be jointly arranged on the air outlet 120, so that heat is exchanged through the two heat exchanger splits 210 or through the two heat exchanger splits 210 and at least two evaporator splits 331.

[0075] It should be noted that the second ends of the two heat exchanger splits 210 are connected to the evaporator structure 300. When the evaporator main body 330 is set on one side, the second end of one heat exchanger split 210 is hinged to the evaporator structure 300, and the second end of the other heat exchanger split 210 is movably connected to the evaporator structure 300, which can also realize the coordination between the heat exchanger main body 200 and the evaporator main body 330.
