DETAILED DESCRIPTION

[0048] As shown in Figure 1 and 2 , the embodiment provides an ice pool test room constant temperature double shell side blowing type ice making air flow system, which can be installed in any indoor 18 or outdoor environment, which is composed of double layer structure of ice pool main body and shell body;

[0049] Among them, the ice pool main body, in this embodiment, has a convex downward convex shape inner space;

[0050] The wall part of the ice pool main body (such as floor 20, inner shell 5 and other structures) is a heat preservation structure;

[0051] The lower area of the inner space is the ice pool part, and in the process of cold air ice making, water 2 is located in the lower part and model ice 1 is gradually generated in the upper part;

[0052] The ice pool part of the ice pool main body is provided with a pool wall insulation layer 3, which can be made of or coated with traditional insulation cotton and other insulation materials, or buried with various types of electric control insulation elements with refrigeration function commonly used in the art.

[0053] The ice pool or the opening position of the ice pool is provided with an ice thickness measuring instrument 13.

[0054] The upper area 16 of the above ice pool main body is provided with a air cooling assembly;

[0055] The air cooling assembly includes cold air emitting device (two-way air cooler) 7, fluid channel (refrigeration air flow horizontal duct) 8 and main guide mechanism (adjustable height main guide plate) 15;

[0056] The cold air emitting device 7 is installed directly above the ice pool, the top of the ice pool main body. Generally speaking, in order to realize the stability of the installation structure, the lower part of the cold air emitting device 7 or its installation position has an air cooler ceiling 9 for realizing the structural installation of the equipment.

[0057] In addition, a temperature measuring instrument 14 is arranged on the ceiling corresponding to the position of the air emitting device 7.

[0058] The fluid passage 8 is symmetrical and respectively connects the two sides of the air outlet of the air emitting device 7, so as to realize the air guiding effect.

[0059] The end of the fluid passage 8, i.e. the air inlet and outlet end of the cold air (when one end does not release cold air, it is the air return port to ensure the circulation of air volume), is provided with a main guide mechanism 15.

[0060] The fluid passage 8 has a support structure (air duct support column) 23.

[0061] The support structure 23 has a heat preservation structure (column outer flow guide heat preservation body) 24 on the outer surface, i.e. in the form of heat preservation cotton covering.

[0062] The vertical backflow plate 21 is arranged above the main guide mechanism 15 on the outer surface of the support structure 23.

[0063] The fluid passage 23 is provided with a flow regulating mechanism (air pipe flow regulating guide blade) 10 at the corner position.

[0064] The outlet direction of the main guide mechanism 15 is opposite to the position of the ice pool, i.e. the model ice.

[0065] The main guide mechanism 15 is a height adjustable structure, which can adopt a conventional flap structure, a sliding structure or the like, and the up and down movement can be controlled by the front end switch of the equipment, or manually controlled by a handle, or in an electric control form.

[0066] The thermometer 15 is arranged at the outlet position of the main guide mechanism 23.

[0067] According to different ice water pool widths, the height of the main guide plate can be adjusted to change the air outlet height, so that the system can adapt to the ice making process requirements of different ice water pool widths within a certain range.

[0068] The angle of the vertical flow guide plate should also be determined at the initial debugging stage in the laboratory to determine the appropriate angle. In the embodiment, the preferred angle is 20°-30° inclined to the column, so that the middle region of the column also has ice making air flow, and the entire ice water pool above can be uniformly blown by the ice making air flow and forced to exchange heat.

[0069] The ice pool body has a shell 4 outside;

[0070] The shell 4 is also a heat preservation structure;

[0071] The shell 4 and the ice pool body have an air layer 6 therebetween;

[0072] The temperature adjusting mechanism (interior-exterior shell heat preservation intermediate area air conditioner) 17 is further installed between the shell 4 and the ice pool main body.

[0073] Effects and advantages of the embodiment:

[0074] In the embodiment, a first shell heat preservation is first arranged in the test building exterior envelope, and the shell heat preservation is a certain thickness of constant temperature air layer inwardly, and then an interior shell heat preservation is arranged.

[0075] The interior of the interior shell heat preservation is a vertical air duct of refrigeration air flow, and the vertical air duct has one on each side of the ice pool test room, and the upper part of the vertical air duct is a cold air machine equipment ceiling, and the cold air machine is arranged in the middle and upper part of the ceiling space, and the cold air machine can blow air in two directions, and horizontal air pipes and guide vanes are arranged on both sides of the cold air machine.

[0076] The lower part of the vertical air duct is a jet flow and backflow air port, and a main guide plate is arranged at the lower part of the air port. Since the lateral vertical air duct of the large ice pool test room has a large span, an air duct support column needs to be arranged in the air duct. In order to improve the uniformity of the refrigeration air flow in the outer area of the column, two vertical guide plates are arranged at the positions of the upper part of the main guide plate on both sides of the column.

[0077] In addition, a guide heat preservation body is arranged outside the column to further improve the wind speed in the area. The refrigeration air flow passes through the adjustable height air port jet flow from the side to blow over the upper part of the ice water pool, and then flows back to the ceiling space from the vertical air duct on the other side.

[0078] The spray crystal growth device is arranged above the ice water pool, and an ice thickness measuring instrument is also arranged above the ice pool, temperature instruments are arranged at the air supply and return air ports on both sides and the area close to the ceiling on the upper part of the ice water pool. Heat preservation measures are also arranged outside the walls of the ice water pool.

[0079] The refrigeration air flow system is flexible and has high jet flow uniformity, and can form model ice with a certain thickness and uniform distribution in the whole test ice pool area within a specified time according to the test process requirements. At the same time, by arranging the combination of the double shell heat preservation structure and the constant temperature air conditioner, the system is less affected by the external environment temperature, and the preparation of the test model ice has high repeatability.
