Yanmar was founded in March 1912 in Osaka, Japan, [2] by Magokichi Yamaoka. [3] [4] When the company began in 1912, it manufactured gasoline-powered engines. [5] In 1920 the company began production of a small kerosene engine. [6] In 1933, it launched the world's first practical small diesel engine, the HB model. [5] [7] [8]

A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
The first combines under that name, the All-Crop 60, had a 60-inch, sickle-bar cutting head, and the popular Model 66 had a 66-inch cutting head. Many of these units are still in working condition, and they are well known for their dependability and low maintenance; however, as they are quite small machines (and now very old), they are not ...
T–s diagram of a typical Rankine cycle operating between pressures of 0.06 bar and 50 bar. Left from the bell-shaped curve is liquid, right from it is gas, and under it is saturated liquid–vapour equilibrium. There are four processes in the Rankine cycle. The states are identified by numbers (in brown) in the T–s diagram.
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
Surface condenser with end plate extended to reveal tube banks. A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations.
