Daikin
is a Japanese multinational conglomerate company headquartered in Osaka. Daikin is the world's largest air conditioner manufacturer. History Daikin Industries Ltd was founded in 1924 as by Akira Yamada. In 1953, Daiflon or polychlorotrifluoroethylene was developed. In 1963 the company was renamed and developed Neoflon. In 1982 it was renamed to the current Daikin Industries Ltd. Daikin entered the North American air conditioning market in 2004. In 2006, Daikin Industries acquired McQuay International, a Minneapolis, Minnesota–based global corporation that designs, manufacturers and sells commercial, industrial and institutional heating, ventilation and air conditioning (HVAC) products. In 2008, McQuay International was rebranded as Daikin-McQuay as Daikin began implementing many of its technologies (including the Daikin Inverter Compressor) and manufacturing processes into McQuay equipment and factories. However, in November 2013, the Daikin-McQuay group was agai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Goodman Global
Goodman Manufacturing is an American company operating as an independent subsidiary of Daikin Group, the world's largest manufacturer of heating, ventilation and air conditioning products and systems. Goodman is located in the $417 million Daikin Texas Technology Park. History Goodman Manufacturing was founded by Harold V. Goodman, in 1975 as a manufacturer of flexible air ducts and plastic blade registers. In 1982, the company acquired Janitrol and entered the HVAC market, expanding its product offering in 1986 to include gas heating products. Harold V.

Air Conditioner
Air conditioning, often abbreviated as A/C (US) or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature, and in some cases, also controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or through other methods, such as passive cooling and ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners but use a reversing valve, allowing them to both heat and cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used in vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming increasingly common in cooler climates. Air conditioners can red ...

Nikkei 225
The Nikkei 225, or , more commonly called the ''Nikkei'' or the ''Nikkei index'' (), is a stock market index for the Tokyo Stock Exchange (TSE). It is a price-weighted index, operating in the Japanese yen, Japanese Yen (JP¥), and its components are reviewed twice a year. The Nikkei 225 measures the performance of 225 highly capitalised and liquid publicly owned companies in Japan from a wide array of industry sectors. Since 2017, the index is calculated every five seconds. It was originally launched by the Tokyo Stock Exchange in 1950, and was taken over by the ''The Nikkei, Nihon Keizai Shimbun'' (''The Nikkei'') newspaper in 1950 in Japan, 1970, when the Tokyo Exchange switched to the TOPIX, Tokyo Stock Price Index (TOPIX), which is weighed by market capitalisation rather than stock prices. History The Nikkei 225 began to be calculated on 7 September 1950, retroactively calculated back to 16 May 1949, when the average price of its component stocks was 176.21 yen. Since July ...

Polychlorotrifluoroethylene
Polychlorotrifluoroethylene (PCTFE or PTFCE) is a thermoplastic chlorofluoropolymer with the molecular formula , where ''n'' is the number of monomer units in the polymer molecule. It is similar to polytetrafluoroethene (PTFE), except that it is a homopolymer of the monomer chlorotrifluoroethylene (CTFE) instead of tetrafluoroethene. It has the lowest water vapor transmission rate of any plastic. History It was discovered in 1934 by Fritz Schloffer and Otto Scherer who worked at IG Farben Company, Germany. Trade names After World War II, PCTFE was commercialized under the trade name of Kel-F 81 by M. W. Kellogg Company in early 1950s. The name "Kel-F" was derived from "Kellogg" and "fluoropolymer", which also represents other fluoropolymers like the copolymer poly(chlorotrifluoroethylene-co-vinylidene fluoride) (Kel-F 800). These were acquired by 3M Company in 1957. 3M discontinued manufacturing of Kel-F by 1996. PCTFE resin is now manufactured under different trade na ...

Manual Pump
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells. History One sort of pump once common worldwide was a hand-powered water pump, or 'pitcher pump'. It was commonly installed over community water wells in the days before piped water supplies. In parts of Britain and Ireland, it was often called ''the parish pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vane Pump
A rotary vane pump is a type of positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. In some cases, these vanes can have variable length and/or be tensioned to maintain contact with the walls as the pump rotates. This type of pump is considered less suitable than other vacuum pumps for high-viscosity and high-pressure fluids, and is . They can endure short periods of dry operation, and are considered good for low-viscosity fluids. Types The simplest vane pump has a circular rotor rotating inside a larger circular cavity. The centers of these two circles are offset, causing eccentricity. Vanes are mounted in slots cut into the rotor. The vanes are allowed a certain limited range of movement within these slots such that they can maintain contact with the wall of the cavity as the rotor rotates. The vanes may be encouraged to maintain such contact through means such as springs, gravity, or centrifugal force. A small amount of oil may ...

Piston Pump
A piston pump is a type of positive displacement pump where the high-pressure seal reciprocates with the piston. Piston pumps can be used to move liquids or compress gases. They can operate over a wide range of pressures. High pressure operation can be achieved without adversely affecting flow rate. Piston pumps can also deal with viscous media and media containing solid particles. This pump type functions through a piston cup, oscillation mechanism where down-strokes cause pressure differentials, filling of pump chambers, where up-stroke forces the pump fluid out for use. Piston pumps are often used in scenarios requiring high, consistent pressure and in water irrigation or delivery systems. Types The two main types of piston pump are the lift pump and the force pump. Both types may be operated either by hand or by an engine. Lift pump In a lift pump, the upstroke of the piston draws water, through a valve, into the lower part of the cylinder. On the downstroke, water passes thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2011 Tōhoku Earthquake And Tsunami
On 11 March 2011, at 14:46:24 Japan Standard Time, JST (05:46:24 UTC), a 9.0–9.1 Submarine earthquake, undersea megathrust earthquake occurred in the Pacific Ocean, east of the Oshika Peninsula of the Tōhoku region. It lasted approximately six minutes and caused a tsunami. It is sometimes known in Japan as the , among other names. The disaster is often referred to by its numerical date, 3.11 (read in Japanese).
