چکیده

In case of energy storage air conditioning system, due to load fluctuation, the traditional control methods can't obtain good effect, the model predictive control method can realize the optimization control system, and can overcome the influence of load fluctuation. In order to realize the predictive control, need to study model of air conditioning system. Ice storage air-conditioning system, by analyzing the mechanism of ice tank, ice melting system outside the tank model is established. First, analyzed the physical structure of ice bath, determine the parameters of ice bath, put forward the control as well as the output of the ice tank. Good model will be built using TRNSYS and MATLAB joint simulation, and the model simulation results and the widely used now BAC coil and TSQINGHUA TONGFANG ice coil characteristic has carried on the contrast, determine the tank model is built by ice in the most good ice tank was simulated under the condition of outlet temperature, and focused on the top 20% of the ice melted and the error of 20%, after put forward the reasonable solution, the interpretation of the ice tank established ice model has practical significance.

Study on Effective Use of an Ice Thermal Storage System with Simulation

It is important to evaluate whether an ice thermal storage system can operate effectively as the way planned at the design stage. While designing an ice thermal storage system, generally, the thermal storage time is calculated by using rated capacity of refrigerator or the heat exchange capacity of ice-on-coil, and the heating capacity time is calculated by using the average ice melting ability...
