Bosch announced a new Climate Control Sensor (CCS) that monitors the level of carbon dioxide
(CO2) for better electronic control of the air conditioning system and a reduction in energy demand.
Complete news:
FARMINGTON HILLS, Mich., March 29 /PRNewswire/ — Bosch has developed a
new Climate Control Sensor (CCS) that monitors the level of carbon dioxide
(CO2) in a vehicle’s passenger compartment while increasing the efficiency
of the air conditioning system. The result is an enhanced electronic
control of the air conditioning system and a corresponding reduction in
energy demand.
When fresh air is fed into the passenger compartment, the
CCS-controlled air conditioning system switches to recirculation mode. This
mode saves energy because the amount of power needed for cooling is
reduced. Using less power for cooling requires less load on the engine,
which drives the air conditioning compressor. Bosch engineers calculate
fuel savings of up to 10 percent when the system is operating in maximum
cooling mode.
The robust and compact CCS uses infrared-based spectroscopy to measure
CO2 levels in the air. This system can reliably measure even minute
concentrations of less than 0.02 percent by volume. The sensor constantly
measures the CO2 level of the air in the passenger compartment, while an
enhanced version also measures air humidity and temperature. This data is
used to precisely control all the actuators of the air conditioning system
and provide for a balanced management of air recirculation.
The Bosch Group is a leading global manufacturer of automotive and
industrial technology, consumer goods, and building technology. In fiscal
2006, approximately 260,000 associates generated sales of 43.7 billion
euros, or $54.9 billion USD. Set up in Stuttgart in 1886 by Robert Bosch
(1861-1942) as “Workshop for Precision Mechanics and Electrical
Engineering,” the Bosch Group today comprises a manufacturing, sales, and
after-sales service network of approximately 280 subsidiaries and more than
12,000 service centers in over 140 countries.
In North America, the Bosch Group manufactures and markets automotive
original equipment and aftermarket products, industrial automation and
mobile products, power tools and accessories, security technology,
thermo-technology, packaging equipment and household appliances. Bosch
employs 24,750 associates in more than 80 primary and 20 associated
facilities throughout the region with reported sales of $8.8 billion in
2006.
