Abstract

The invention relates to an ice accumulating cold air-conditioning system. By adopting the proposal, the air-conditioning system can work in five cooling modes, so as to utilizing the electrical power at trough period of electricity utilization to the utmost extent, and use the way of double series connection for conveniently changing various current states with suitability; due to the unique serpent-type steel coiled pipe structure and excellent heat transfer property, the ice accumulating cold air-conditioning system leads the water to be frozen into ice layers having the thickness of 25MM to be covered on the outer wall of the coiled pipe in final period of refrigeration, gaps exist among the ice layers, the temperature of the water is still 0 DEG C, and no ice bridge is formed; therefore, uniform heat exchange can be ensured, the temperature at the glycol outlet is consistent when refrigeration agent is adopted, the cold extraction process can be controlled, and the ice extraction rate reaches 100%. A single serpentine tube with the length of 100m is wound on a support frame, external-melt ice equipment can provide chilled water with consistent 1 DEG C, and the use of CFC and the emission of CO2 can be reduced by district cooling. The invention also provides a method for effectively balancing electrical load.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an ice storage air conditioner. Background technique [0002] In recent years, with the rapid development of my country's economy, the power industry has also developed rapidly. However, in some economically developed areas, electricity consumption is still very tight, which has become a bottleneck restricting economic development. Due to the low load rate of the power grid and the large peak-to-valley difference in the power supply system, there is a shortage of power supply during peak hours of electricity consumption. At the same time, urban life and commercial electricity consumption The rapid growth, especially the sudden increase of electricity load in summer, has made the urban power grid far from being able to adapt. Therefore, "transferring peak power" and making full use of nighttime power has become an important and long-term goal for the government and power management department...
