The invention discloses an energy storage type on-line emergency cold source system. The energy storage type on-line emergency cold source system comprises an ice making pump, a controllable phase change heat exchanger, a cold source, an ice storage tank, a liquid level meter, an ice water pump, a cold discharge heat exchanger, a spraying device, an ice slurry pump and a concentration on-line measurement device. The bottom of the ice storage tank passes through the ice making pump. One side of the controllable phase change heat exchanger is connected with the top of the ice storage tank, and the other side of the controllable phase change heat exchanger is connected with the cold source. An inlet of the ice water pump is connected with the bottom of the ice storage tank, and an inlet of the ice slurry pump is connected with an ice-rich layer of the ice storage tank. The spraying device is arranged in the ice storage tank and located above an ice layer. An outlet of the ice water pump and an outlet of the ice slurry pump are combined and connected with the spraying device through one side of the cold discharge heat exchanger, and the other side of the cold discharge heat exchanger is connected with a cold usage tail end. The concentration on-line measurement device is arranged on a pipeline which exists after the outlet of the ice water pump and the outlet of the ice slurry pumpare combined. The liquid level meter is used for measuring the liquid level of the ice storage tank. The energy storage type on-line emergency cold source system has the advantages of being compact in system structure, high in cold storage energy efficiency, high in cold delivery capacity, high in load response speed and the like.
Description
technical field [0001] The invention relates to the technical field of cooling systems, in particular to an energy storage type online emergency cold source system. Background technique [0002] The emergency cold source plays an important role in the operation of each system. For example, when the battery system is operating under high-rate charging and discharging and dangerous conditions, the emergency cold source system is required to prevent the temperature from rising sharply. When the air-conditioning system and data center are interrupted in cooling, It is necessary to activate the emergency cold source to ensure the normal operation of the system. The emergency cold source system pays attention to timeliness, and requires timely cooling in a relatively short period of time, and can meet the cooling demand of the system. At present, most of the cold source systems are large in size, and the cooling speed and load response speed are slow, which makes it difficult to ...
