The article considers some ways to increase energy efficiency of production. The urgency and necessity of systems application that allow to utilize the heat of steam-air mixes as energy wastes is substantiated. Different variants of utilization are considered and their disadvantages are highlighted. The possibility of using a heat pump for a deeper heat utilization of steam-air mixtures is proposed. The design of the automated workplace for researching the processes of steam-air mixtures heat recovery is described, which will allow conducting preliminary research before building the utilization systems for a particular technological process. The automated workplace includes a technological system that allows to simulate a steamair mixture with specified parameters, to utilize its thermal energy. Deep utilization is achieved through the use of "waterwater" heat pump. The system is equipped with sensors, which allow measuring the values of all parameters that are interest, and the executive devices. Also, an automated workplace includes software that runs on a personal computer, and allows you to manage the progress of the experiment, both manually and automatically, to record all the data. In an automated experiment, all variables are stabilized, except for one that varies according to a given law. The results of experiments on the study of the modes of the evaporator performed in the automatic mode are presented. The results represent a family of quasistatic dependencies of the process variables. The analysis of the results of experiments was carried out. The conclusions are based on the results of experiments and ways of improving the evaporator control system are considered [ABSTRACT FROM AUTHOR] |
