Abstract

The invention relates to a high-temperature phase-change cold storage device, and belongs to the technical field of phase-change cold storage. When a refrigerator works, a solenoid valve is switched off, a cooling agent evaporates in a shell-tube evaporator and absorbs heat to take away surrounding heat, and then refrigerating is achieved; and cooling agent gas generated after evaporation enters acompressor to be compressed, then condensed in a condenser and enters the shell-tube evaporator to achieve refrigerating after being dried and filtered through a drying and filtering device, and a cycle is formed. When the cold storage device works, the solenoid valve is switched on, a refrigerating agent enters an ice making device through the shell-tube evaporator, a part of the refrigerating agent enters a cold storage tank through a reverse osmosis membrane under the action of the reverse osmosis membrane and generates phase change in the cold storage tank to form ice slurry, water heatedby a heater enters a heat exchange coil pipe arranged in the cold storage device to achieve heat exchange with the ice slurry in the cold storage tank, and then refrigerating is achieved.

Description

technical field [0001] The invention relates to a high-temperature phase change cold storage device, which belongs to the technical field of phase change cold storage. Background technique [0002] With the rapid development of my country's economy, my country's power supply continues to be tense. An important strategy to solve the peak-valley power imbalance is to use cold storage air-conditioning systems. With a good external economic environment, the application of cold storage air-conditioning technology has great development prospects in our country. [0003] High-temperature phase-change cold storage technology, that is, to use the phase-change latent heat characteristics of the cold-storage medium with a phase-change temperature in the range of 7-12°C, and to add a high-temperature phase-change cold storage device to the air-conditioning system, without changing the operating conditions of the existing air-conditioning system. , the storage and release of cold energy ...
