The PCX Electric has an interior permanent magnet traction motor with peak and continuous rated outputs of 4.2 and 0.98 kW (5.63 and 1.31 hp), respectively, drawing from two removable Honda Mobile Power Pack batteries connected in series; each battery provides 50.4 V and 20.8 A-hr, giving the scooter a range of 42 km (26 mi).

In 1939, Packard became the first automobile manufacturer to offer an optional air conditioning unit in its 1940 model year cars. [2] [3] These bulky units were manufactured by Bishop and Babcock (B&B), of Cleveland, Ohio and were ordered on approximately 2,000 cars. [4] The "Bishop and Babcock Weather Conditioner" also incorporated a heater.
Just as horsepower and candlepower were intuitive units of measure for people living through the transition from horse to steam power [3] and from flame-based to electric lighting, so was the ton of refrigeration an intuitive unit of measure during a technological change, as the ice trade gradually included growing percentages of artificial ice ...
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER), which is defined by the Air Conditioning, Heating and Refrigeration Institute in its 2008 standard AHRI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment. [61]
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...
Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:
An air handler, or air handling unit (often abbreviated to AHU), is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning system. [1] An air handler is usually a large metal box containing a blower , furnace or A/C elements, filter racks or chambers, sound attenuators , and dampers . [ 2 ]
From 2009 the Honda CBR1000RR and CBR600RR sport bikes are optionally equipped with an integrated Dual CBS and ABS system which uses an electronic control unit to distribute hydraulic pressure between front and rear brakes. [16] The combined anti-lock braking system is called C-ABS. [17]
