Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an ice cold storage device structure and an air conditioner. Background Art

[0002] At present, ice storage technology mainly uses the latent heat of ice phase change to store cold. During the low-power consumption period at night, the refrigeration unit is used to make ice in the ice storage equipment to store cold. During the peak power consumption period during the day, the ice in the ice storage equipment is melted to provide cold for the air conditioner. Since the temperature is lower at night, the power consumed by refrigeration can be reduced, achieving "peak shaving and valley filling" of electricity, thereby significantly reducing the operating costs of the air conditioning system.

[0003] The ice storage device is mainly composed of a heat exchange tube and an outer frame. The ice storage device is placed in the ice storage equipment. The low-temperature medium flowing in the heat exchange tube absorbs the heat of the water in the ice storage equipment, thereby cooling the water in the ice storage equipment and gradually freezing. However, during the ice storage process, as the thickness of the ice layer increases, the ice layer will overlap between the heat exchange tubes, resulting in a limited volume of the ice layer and a reduced heat exchange efficiency of the heat exchange tubes, thereby reducing the ice storage rate and the amount of stored energy. Therefore, how to slow down the current ice layer overlap between the heat exchange tubes and increase the thickness and volume of the ice layer during the ice storage process within a certain space has become the direction of efforts of those skilled in the art.

[0036] The heat exchange tube 1 structure is set to be a curved pipe structure formed by splicing a straight tube section 2 and a curved tube section 3. The curved tube section 3 is set to be a U-shaped curved tube, and the vertical projection of the curved tube section 3 is wavy, that is, the distribution of multiple straight tube sections 2 is wavy, and the ice layer cylinder formed with the axis of the straight tube section 2 as the center has the same volume as the ice layer cylinder formed by the straight tube sections 2 distributed in a straight line, and the radius is half of the distance between two adjacent straight tube sections 2. However, the heat exchange tube 1 with the straight tube sections 2 distributed in a wavy manner has a small overall width, that is, the distance between the two straight tube sections 2 at both ends is small. Therefore, the straight tube sections 2 distributed in a wavy manner in the same volume can form a larger volume of ice layer, store more energy, and thus improve the cold storage efficiency. Preferably, the heat exchange tube 1 is made of stainless steel.
