PARAMETRIZAÇÃO DA CARGA TÉRMICA DE UM RESTAURANTE ATRAVÉS DE UM CÓDIGO COMPUTACIONAL

Abstract

Refrigeration systems are essential for the thermal comfort of people, in addition to other important existing applications. Correct sizing of air conditioning equipment represents system efficiency and, consequently, better performance. Therefore, this study deals with the development of a computational code in the EES (Engineering Equation Solver) platform to determine the energy consumption of the thermal door of the evaporator units (thermal load) of a fictitious medium-sized restaurant. The restaurant is located in Recife-PE, accepts 250 customers and 17 responsible employees, in addition to indoors. The study also presents the inclusion of a paved surface parking lot and its influence on energy input also through light into the restaurant's interior, in addition to parameterized results of the consequences of the number of people entering the restaurant's interior. From these data, it was possible to observe the customers and resources, through the thermal load of the restaurant, to the point of considering the implementation of the Variable Refrigerant Volume (VRV) system at the point of reflection of the thermal load. The script used for the human comfort of load obeyed as current norms, related to systems that aim at the thermal in closed places. It was verified that the inclusion of a paved surface parking lot increases by 900% the insolation values for the interior of the restaurant. In this way, it is concluded that the computational study can result in a more real and reliable car system to the demand of the establishment.
