The invention discloses a cold energy storage type central air conditioning system and an operation method thereof. The cold energy storage type central air conditioning system comprises a refrigerating unit, a cooling water circulating device, a chilled water circulating device, a first cold energy storage water tank and a second cold energy storage water tank, wherein the first cold energy storage water tank and the second cold energy storage water tank are arranged in parallel, the first cold energy storage water tank is a cold energy storage water tank adopting water, the second cold energy storage water tank is a cold energy storage water tank adopting a high-temperature phase change material, the low-temperature water in the first cold energy storage water tank and cold-energy-release water in the second cold energy storage water tank are mixed and then exchange heat with chilled water of an air conditioner through a heat exchanger so that the chilled water in the air conditioning system can completely meet the water utilization temperature requirement of the central air conditioning system, meanwhile, under the premise of the same cold energy storage capacity, through the cold energy storage mode in which the second cold energy storage water tank is connected with the first cold energy storage water tank in parallel, the problem that a large amount of building area is occupied due to the fact that a water cold energy storage unit is independently used can well solved, and the feasibility and the economical efficiency of a cold energy storage system are greatly improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration, in particular to a cool-storage central air-conditioning system and an operating method thereof. Background technique [0002] Cold storage technology is an important technology to improve energy utilization efficiency and reduce equipment cost. It can be used to solve the contradiction between energy supply and demand mismatch. The application prospect is a research hotspot in the world, and this technology is widely used in the current central air-conditioning system. [0003] Existing central air-conditioning systems generally adopt a single cold storage method, that is, water cold storage, ice cold storage or phase change cold storage are used alone. However, a single cold storage method has its own limitations, such as: water cold storage. Large volume; the method of phase change cold storage has the advantages of high energy efficiency of water cold storage and high density of ice st...
