Abstract
Regardless of the vehicle's application, the thermal comfort of the vehicle's
occupants and driver is given increased attention. Maintaining a sense of thermal comfort, whether
for safety, health or occupant thermal well-being reasons, is one of the most important goals of
heating, ventilation and air conditioning (HVAC) systems. There are a significant number of
physical variables that affect thermal comfort. Therefore, evaluating thermal comfort has always
been a complex issue and has attracted the attention of researchers. The feeling of thermal comfort is
provided by factors that depend on the heat exchange between the human body and the external
environment. It is well known that one of the requirements to be fulfilled is to find a person in
thermal neutrality in the environment according to the comfort equation.
The article describes and evaluates the following indicators: DTS (dynamic thermal
sensitivity), TS (thermal sensitivity), PMV (predicted mean voice) and PPD (predicted percentage of
dissatisfaction). The most common models for evaluating thermal comfort, namely the Predicted
Mean Vote (PMV), Taniguchi’s model, Zhang’s model and Nilsson’s model in a variety of car cabin
conditions, have been reviewed. The limitations of these models in terms of the objectivity of the
results obtained are analysed.
