Problems solved by technology
In the double-slot type, there is always one tank that cannot be used, and the space utilization rate is low; the operation of the multi-slot system requires multiple valves to switch, the system is complex, and the operation control is difficult; the labyrinth water flow rate is not easy to control, and it is easy to form a vortex or a short circuit to cause dead In addition, there are some disadvantages such as mixing of cold and warm water and large water resistance; the diaphragm in the single-slot diaphragm type is continuously pulled up and down, which has high requirements for the membrane and low practicability; The density of water is the highest at 4°C, and the phenomenon of "lower cooling and upper heating" without stirring is used to carry out natural temperature stratified cold storage, but precise design and construction are required to ensure that the thickness of the thermocline layer is as small as possible. In order to improve the efficiency of cold storage, and the lowest cold storage temperature is not less than 4°C

Embodiment Construction
[0024] The present invention will be further described below in combination with specific embodiments.
[0025] Cylindrical dynamic water storage device with rotary motion partition of the present invention, such as figure 1 As shown, it includes a cylindrical water reservoir 3, a central shaft 6, a fixed waterproof and heat-insulating baffle 2 and a rotating partition 1.
[0026] The central axis 6 is fixed on the central axis of the cylindrical water reservoir 3;
[0027] There are two types of structures for fixing the waterproof and heat-insulating baffle plate 2 and rotating and moving the partition 1:
[0028] The first type: if figure 1 As shown, the fixed waterproof and heat insulation baffle passes through the central axis and is fixed inside the cylindrical water storage, and divides the inner space of the cylindrical water storage into two equal parts; the rotation movement is separately arranged inside the cylindrical water storage , intersect with the fixed wat...

The invention discloses a cylindrical dynamic water cold storage device with a rotation partition.The rotation partition installed in the cylindrical water cold storage device is mainly made of waterproof and heat preservation material.During cold storage / release, the partition is dragged by an external motor to rotate and slide along a rotation rail, and therefore the cold storage / release process without temperature layering is achieved.The temperature layering of a conventional water cold storage device is eliminated, and therefore cold storage / release efficiency is far better than that of other similar water cold storage devices.
Description
technical field [0001] The invention relates to the technical field of air conditioning and refrigeration, in particular to a cylindrical dynamic water cold storage device with rotating motion partitions. Background technique [0002] Water storage air-conditioning technology is a technology that uses sensible heat of water to store cold energy: it is made of refrigeration equipment during the time period when no cooling capacity is needed or less cooling capacity is needed (when the power grid is at a low point at night, and the air-conditioning load is also low at the same time). The low-temperature water is stored and then used during the peak period of air-conditioning or process cooling (when the power grid peaks during the day, it is usually also the peak of the air-conditioning load) to meet the demand. As an effective way to shift peaks and fill valleys of electric power, it can achieve the effect of economical operation, energy saving and environmental protection, a...
