Análise de carga térmica e melhoria na eficiência térmica de uma residência de alto padrão

Abstract

The present study approaches the thermal load analysis of a high standard residence, currently in construction in the residential condominium, located in Dourados, Mato Grosso do Sul, the objective is to obtain a better dimensioning and reduction of costs for the installation of the air conditioning system. The study is based on the ASHRAE CLTD methodology, Cooling Load Temperature Difference, recommended for the design of simpler systems, according to the item 28 of the ASHRAE 2001 Fundamentals Handbook. After obtaining the results from the original project, a proposal for improvement was formulated, aiming at a costs reduction regarding both equipment and later consumption expenses. The proposal included cost cuts on HVAC equipment to be installed, reduction of the potential installation of solar energy and costs associated with oversized equipment. Therefore, changes were proposed in the constructive aspect of the roof and the use of glasses with lower heat absorption, besides the analysis of feasibility of implementing the proposed changes.
