The Unitary Products business group manufacture products in categories including air conditioners, air coolers, [7] commercial refrigerators, water coolers, and water dispensers. Voltas [8] is the largest air conditioning brand in India. It started manufacturing air conditioners in the 1960s under license from the Carrier Corporation. [9]
It was originally defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. [1] [2] The modern definition is exactly 12,000 Btu IT /h (3.516853 kW). Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of ...
Air conditioning equipment will reduce the absolute humidity of the air processed by the system if the surface of the evaporator coil is significantly cooler than the dew point of the surrounding air. An air conditioner designed for an occupied space will typically achieve a 30% to 60% relative humidity in the occupied space. [51]
In February 1980, a power steering for the wide vehicles was added as an option, at the end of the same year a narrow 1.5 ton and a wide 3.5 ton followed. New diesel engines 4D30 (indirect injection, naturally aspirated, 90 PS [66 kW]) and 4D31 (direct injection naturally asparated or turbo charged, 115 PS [85 kW]) were added in November 1982.
An air conditioning system, or a standalone air conditioner, provides cooling and/or humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions.
The water ton is used chiefly in Great Britain, in statistics dealing with petroleum products, and is defined as 224 imperial gallons (35.96 cu ft; 1.018 m 3), [22] the volume occupied by 1 long ton (2,240 lb; 1,016 kg) of water under the conditions that define the imperial gallon.
The basic civil and criminal laws governing the citizens of India are set down in major parliamentary legislation, such as the civil procedure code, the penal code, and the criminal procedure code. [18] Similar to the Union government, individual state governments each consist of executive, legislative and judiciary branches.
In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail. The overhead line (3) and feeder (5) are on opposite phases so the voltage between them is 50 kV, while the voltage between the overhead line (3) and the running rails (4) remains at 25 kV. Periodic autotransformers (9 ...
