Method for enhancing cold-storage density of cold storage air conditioner system and cold storage air conditioner system

Abstract

The invention relates to a cold storage density improving method for the cold storage air conditioning system and a cold storage air conditioning system. The method of the invention adopts the technical proposal that during the cold discharging stage, under the state that the refrigerating unit is started, a part of high-temperature cooling water is taken as low-temperature cooling water to replace the water cooling system to be supplied to the condenser of the refrigerating unit; when the cold storage is required, the high-temperature cooling water is refrigerated and is changed into the low-temperature refrigerated water by the condenser of the refrigerating unit. The cold storage air conditioning system of the invention comprises a refrigerating unit, a cold storage equipment, a chilled water pump, an air conditioning unit, a cooling water system, one to a plurality of low-temperature cooling water circulating pipelines and two to a plurality of high-temperature refrigerated water refrigeration pipelines. The cold storage density improving method for the cold storage air conditioning system and the cold storage air conditioning system have the advantages that electric power consumption in the power consumption peak time can be more reduced, the operation cost can be reduced, and the cold storage density can be increased, thereby a positive effect can be taken on the peak load shifting of the electric network.

Description

technical field [0001] The invention relates to a method for increasing the cold storage density of a cold storage air conditioning system and a cold storage air conditioning system. Background technique [0002] Since the reform and opening up, the electric power industry, as one of the basic industries of the national economy, has achieved considerable development. However, the growth of electricity still cannot meet the needs of the rapid development of the national economy and the sharp increase in people's daily electricity consumption. The situation of power shortage in the country still exists, the load rate of the power grid is low, the peak-valley difference of the system is increased, and the peak power is seriously insufficient, resulting in frequent power grids. Pull the grid and cut power. Effectively transfer the electricity from the peak period to the trough period, so that the power consumption of the entire power grid is more uniform, which can reduce the p...
