Embodiment
[0018] figure 1 It is a dynamic ice-making system in the prior art. The refrigeration main unit 1 and the second dynamic ice-making unit 3 form a cold source cycle through the antifreeze liquid delivery connection channel 2, and the antifreeze liquid delivery connection channel 2 is connected in series with the antifreeze liquid pump 9 as the cycle. driving force. The second dynamic ice making unit 3 and the ice storage tank 5 form an ice making cycle through the first slurry-water mixture delivery pipe 4, the first connecting water pipe 6, the first water pump 7, and the first connecting water pipe 8, and the first water pump 7 serves as the cycle power.
[0019] refer to figure 2 As shown, in order to further illustrate the composition of system resistance, the simplified plate heat exchanger of the second dynamic ice making unit 3, the slurry-water separator and the first water pump constitute a relatively closed system, and the concentrated TBAB slurry is a plate heat ...

The invention discloses a tetrabutyl ammonium bromide (TBAB) slurry and water separation type dynamic ice storage system, which comprises a refrigeration host machine and a first dynamic ice-making set which form cold source circulation through a non-freezing solution connection channel, wherein the non-freezing solution connection channel is connected in series with a non-freezing solution pump; the first dynamic ice-making set and an ice storage tank form ice-making circulation through a first slurry and water mixture conveying pipe, a first connection water pipe, a first water pump and a second connection water pipe; the first dynamic ice-making set comprises a platy heat exchanger; an overcooling relieving instrument and a slurry and water separator are sequentially arranged on the first slurry and water mixture conveying pipe; the other side of the slurry and water separator is connected with a slurry and water separator and then connected to the ice storage tank; one side of the lower part of the second slurry and water mixture conveying pipe is connected with the first connection water pipe; and the other side of the lower part of the slurry and water separator is connected to the ice storage tank sequentially through a fifth connection water pipe 18, a fourth connection water pipe, a check valve, a second water pump and a third connection water pipe. The flow and the lift in a corresponding closed system can be determined, and a water pump is arranged before delivery; a pipeline in the corresponding closed system is short, and the lift is small, so that the power consumption of the water pumps is low; and furthermore, the water supplementation amount is small, so that the power consumption of a water supplementation pump is low.
Description
technical field [0001] The invention relates to the technical field of TBAB envelope compound slurry cold storage, in particular to a dynamic cold storage system. [0002] Background technique [0003] Tetrabutylammonium bromide (TBAB) encapsulating compound slurry is a high-density energy storage and latent heat transport material with a phase transition temperature of 5-12°C, which can be widely used in industrial and commercial large-scale central air-conditioning cold storage systems. [0004] Dynamic cold storage means that the TBAB aqueous solution is cooled to a supercooled state in the plate heat exchanger, and then enters the supercooled remover, and the supercooled state is released to become a slurry-water mixture. Because the TBAB water solution does not freeze or solidify on the surface of the plate heat exchanger, the ice layer thickness does not increase continuously in the traditional static ice storage system, and the heat exchange effect is very good, so th...
