چکیده
The paper presents the integrated application of two methods during testing HVAC system efficiency in cabins HUMMER ?1151A1 and OAR 1RL-128D off-road vehicles. Spatial measurements change air temperature per time have been performed at three vertical levels (head, knees, feet) driver passengers, which totals to 15 measuring points vehicle. main goal was evaluate accurately heating cooling relation interval required attain a designed comfort vehicle cabin, on condition that difference ambient does not exceed 10?C. With view more efficient evaluation thermal cabins, also predicted mean vote percentage dissatisfied indices. Standard surveys ask subjects about their sensation seven-point scale from cold (?3) hot (+3). This research is carried out according based ISO 7730, ASHRAE 55, SORS 8419 standards.

Reinforcement Learning-based Thermal Comfort Control for Vehicle Cabins
Vehicle climate control systems aim to keep passengers thermally comfortable. However, current systems control temperature rather than thermal comfort and tend to be energy hungry, which is of particular concern when considering electric vehicles. This paper poses energy-efficient vehicle comfort control as a Markov Decision Process, which is then solved numerically using Sarsa(λ) and an empiri...
متن کاملComparison of Thermal Comfort by Radiant Heating and Convective Heating
Currently, convective heating with a heat-pump system, which has high energy efficiency, is popular for room heating. However, it is possible that energy savings using convective heating can be further improved using heat pumps that service both occupied and unoccupied spaces. Moreover, convective heating increases vertical temperature gradients in a room; thus, it is hard to say whether occupa...

Parameters and Models of the Vehicle Thermal Comfort
Nowadays, efforts are being made to estimate the thermal comfort in vehicles by measuring each environmental parameter air temperature, air humidity, mean radiant temperature, air velocity, human activity and clothing insulation. An optimum level of comfort in the vehicle is obtained only by using an automatic air conditioning and climate control system. The paper focuses on the analysis of the...
