"  A car&amp;#039;s cabin is a crowded environment with a multiplicity of components and systems vying for valuable space, so the idea of combining the Heating, Ventilating and Air-Conditioning (HVAC) system with the seat seems a pretty neat idea, which is precisely what Delphi has done. The system is part of the E3 HVAC Seat, which combines Delphi&amp;#039;s Diavia HVAC application capability with the COBO group&amp;#039;s steering column, seat, lighting, electric and electronic devices. &amp;quot;Combining Delphi&amp;#039;s new HVAC system with the COBO seat provides equipment manufacturers the opportunity to keep operators comfortable while simplifying the overall cabin design and installation process,&amp;quot; said Roberto Grotti, managing director, Delphi Diavia. Designed for medium-size vehicle or equipment cabins or small rooms, the E3 HVAC has a cooling capacity of 6.2 kW and a heating capacity of 5.8 kW. It can provide climate control for the cab only or for the cab and seat cushion by channeling air flow from the vents. By adjusting the vents, the operator can select the most comfortable cab temperature and keep the seat dry. Air is cooled through an evaporator provided with an expansion valve and using the cooling gas from the AC system. Air is warmed using a heater containing the fluid coming from the endothermic motor. The air is circulated using an electric fan and the air flow is managed by an electronic voltage regulator PWM (pulse width modulator) allowing a linear voltage adjustment at the ends of the fan. Since the seat and HVAC unit are fully integrated, plug and play installation is simple and design and assembly time are reduced.
