Introduction to the development history of air energy heat pump drying technology
The basic thermodynamic theory of heat pumps originated from the Carnot cycle proposed by French engineer Carnot in 1824. In 1852, the British professor Thomson first proposed a heat pump idea, which was called a "heat multiplier" at that time. In the 1940s and 1960s, heat pump technology entered a period of rapid development, and various heat pump devices were used in schools, hospitals, offices and other places.
