Cold supply system and cold supply method thereof

Abstract

The invention provides a cold supply system and a cold supply method thereof. The cold supply system comprises first refrigeration equipment, second refrigeration equipment and cold storage equipment,the first refrigeration equipment and the cold storage equipment are used for providing a first medium for end equipment for cold supply to the end equipment, the second refrigeration equipment is used for providing the first medium for the cold storage equipment to carry out cold charging on the cold storage equipment, a cooling side medium input port of the second refrigeration equipment is used for receiving the first medium output by the end equipment, a freezing side medium input port of the first refrigeration equipment is connected with a cold supply side medium output port of the second refrigeration equipment, and is used for receiving the first medium output by the cooling side medium output port of the second refrigeration equipment, through the system and the method, cold supply stability of the end equipment is ensured, and adjustment of the cold storage amount of the cold storage equipment is reinforced.

Description

technical field [0001] The present application relates to the technical field of cooling, in particular to a cooling system and a cooling method thereof. Background technique [0002] In order to solve the problem of space heat dissipation, such as the heat dissipation problem of large computer rooms, it is usually necessary to deploy air-conditioning equipment. The air-conditioning equipment includes terminal equipment and water chiller equipment. Reduce space temperature. In some special cases, such as the sudden power failure of the chiller equipment, temporary power generation equipment, such as diesel generators, is required to supply power to the chiller equipment, so as to ensure that the chiller equipment can continue to provide cooling for the terminal equipment normally. However, diesel generators It takes a certain amount of time to start the generator and restart the chiller equipment under the power supply of the diesel generator. During this period, the heat g...

Problems solved by technology

On the one hand, this way makes the cold storage equipment in the process of being filled with cold, there will be a part of the medium with a higher temperature flowing to the terminal equipment, which will affect the cooling stability of the terminal equipment; on the other hand, due to the cooling medium required by the terminal equipment The temperature of the water chiller equipment is fixed, and the chiller equipment, cold storage equipment and terminal equipment are connected in series, so the temperature of the cooling medium output by the chiller equipment is determined according to the temperature of the cooling medium required by the terminal equipment, that is, It is said that the temperature of the cooling medium input from the chiller equipment to the cold storage equipment is fixed. Since the cold storage capacity of the cold storage equipment is mainly affected by the capacity of the cold storage equipment and the temperature of the cooling medium output from the cold storage equipment, in this case, the cold storage equipment The total amount of cold storage is also fixed, which makes it difficult to adjust the cold storage capacity of the cold storage equipment
