The quest for individual comfort is driving the growth of multizone LV HVAC systems involving front and rear applications

Technology Trends

Evolving customer comfort expectations and the need for individual thermal comfort are expected to drive the demand for multizone HVAC systems, with four-zone HVAC systems forecast to grow by more than 75% between 2017 and 2023.

The extreme swings in ambient temperature witnessed across the world have made cabin temperature control an indispensable part of passenger comfort. Automotive heating, ventilation, and air conditioning (HVAC) systems too have transitioned from the rudimentary and optional comfort feature of yesteryears to a standard necessity in today’s competitive automotive market. The earliest attempts in cabin temperature control were mainly the result of private commissions in the 1930s looking to improve passenger cabin comfort although major auto manufacturers had their own systems in parallel development. These early development programs ran into multiple obstacles that needed to be overcome before commercially viable HVAC systems could be offered to customers. Many changes have been made since then to accommodate new automotive designs, improve fuel efficiency, gain environmental acceptability, enhance passenger comfort, provide health benefits, and increase passenger safety.
