Resumen
The existence of floating ice in ice storage tanks in an ice storage system affects the normal operation of the ice storageautomatic control system. For the ice storage tank in an ice storage system, the ice “problem”, puts forward the way ofmelting ice in an ultrasonic assisted manner. This paper establishes a polynomial mathematical model of observation datachanges over time, by setting a variable’s value used to model the polynomial fitting method. It could be used in the designand operation index model or higher polynomial model fitting process of melting ice. Ultrasonic wave is used to solve thefloating ice problem of ice storage tank in the operation of ice storage, and the effects of ultrasonic power density, ice-waterratio, ice size, initial ice amount and other parameters on the characteristics of ice melting are tested and analysed throughexperiments, which provides an important reference for the practical application of this technology. It is found that theultrasonic wave can obviously promote and strengthen the melting of ice, and the influence of power, ice–water ratio andice size conforms to the normal theory and practice law. The greater the power, the smaller the ice–water ratio and thesmaller the ice size, the faster the melting speed will be. Due to the multiple effects of technology and economy, the powerdensity has an optimal value, which needs to be optimised according to the actual situation in the application. For largesize ice, the promotion effect of high-power ultrasonic on melting ice is more obviou
