Contribuții la îmbunătățirea parametrilor tehnico-economici ai instalațiilor frigorifice din punctele de colectare a laptelui

Abstract

The aim of the study is to reduce electricity consumption in rural milk collection points from the popu-lation. The paper presented a study on milk cooling refrigeration installations used at milk collection points in the Republic of Moldova. The design of the installation and the ratio of its electricity consumption nodes were analyzed. In order to reduce energy consumption, solutions have been proposed to improve the constructive-technological parameters of the electric motors in the refrigeration installations for milk cooling. It was proposed to modernize the asynchronous motors by placing permanent magnets on the rotors, which will increase the efficiency and the power factor of the motor, therefore reducing the consumption of active and reactive energy in the electrical network.
