An improved optimization adjustment strategy for building heating ventilation and air conditioning (Heating Ventilation Air Conditioning, HVAC) is proposed. The energy consumption model of heating/refrigeration established by using the instantaneous balance heat, then optimal operation HVAC based on weather forecast data constructed in range user temperature comfort. Finally, MATLAB TRNSYS simu...

The two primary functions of a vehicle climate control system are safety through de-icing and de-fogging windows, and occupant thermal comfort. However, vehicle air-conditioning systems can significantly impact fuel economy and tailpipe emissions of conventional and hybrid electric vehicles (HEVs) and reduce electric vehicle (EV) range. In order to meet the new U. S. Supplemental Federal Test P...

This paper introduces the dual-mode refrigeration system for ice storage air conditioning. A computational model relating to the exergy loss amount and loss rate is developed in each component of the refrigeration cycle loop. A case study is presented to demonstrate the applicability of the model developed. Exergy analysis results of the refrigeration system in ice storage operating mode are co...

this review based upon studies searched from the major scientific libraries has the objective of clarifying what is fitness training in modern days, the implications that it has on health in both youth and elderly and finally discuss fitness training practical implications.the prisma statement was partially adopted and a number of 92 items were selected, according to the inclusion criteria. res...

The present study investigates the effectiveness of thermostat control strategy in cooling energy consumption in residential buildings. To evaluate the energy consumption, two scenarios including a residential zone with and without the thermostat control system are assumed. The TRNSYS software provides an efficient numerical tool to model and evaluate a cooling system. Furthermore, since solar-...

spreading wood particles and attached colored materials in work places can cause many problems for woodwork industry workers. the aim of this study is to design and implement a local exhaust ventilation system to control wood dust and isocyanates simultaneously. the study was conducted on 18 workers in the paint workroom of a wood door industry. at first, an overview of the workplace indoor air...
