Review of HVAC thermal comfort and energy efficiency in commercial buildings using air recirculating system

Abstract

HVAC is one of the largest consumers of electrical energy in residential and commercial buildings. Reducing of consumption of energy without compromising thermal comfort may have environmental and financial benefits. Thermal comfort expresses satisfaction with the thermal environment is one of the parameters necessary in building style that in depth modelling and standardization exist. in commercial buildings if thermal comfort is not satisfactory that may effect on human life , which may cause problematic behaviour that forms a heavy burden for skilled and informal careers day and night. For incising of thermal comfort and energy efficiency in commercial buildings HVAC heat load calculations are most important parametars.in commercial buildings (software field) the objective of HVAC designer is provided supportive and comfortable home environments for each people without any human problems to their careers negative effects of hot summers. This paper, supported literature review provides an outline of concerning thermal comfort and also energy efficiency to implementation of heating, ventilation and air-conditioning (HVAC) systems.
