ANÁLISE DE DOIS CONTROLADORES DE UM CONDICIONAMENTO DE AR, VISANDO A EFICIÊNCIA ENERGÉTICA

Abstract

This study discusses the energy growth, and increase the life of refrigeration equipment, by replacing commands from manual to automatic. The analysis was made in a cinema in the city of Varginha / MG, where movie rooms with confined spaces are found, and with frequent flows of people; In the current installation its climate controlled appliances are VRF (Variable Refrigerant Flow), manually controlled, being turned on at the beginning of operation and turned off at the end, consequently have a low energy efficiency, and alelo greater wear on its operation. The objective of the following work is to evaluate the efficiency of the restructuring of climate monitoring with the installation of a Programmable Logic Controller (PLC), connected to the ticket sales system, in order to be activated during the sessions and turning off in periods of absence of people, and with exact proportions in relation to the number of customers with the number of equipment connected, without decreasing their thermal comfort, and allowing a significant percentage in their energy efficiency. It is concluded that with the automatic monitoring, imminent with the VRF system, it presents results relevant to energy consumption and its efficiency, due to the HVAC, is appropriate according to the session times, due to the system being inverted.
