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.
When the household central air conditioner entered the market, it was mainly to meet the needs of high-end villas, and the price was indeed relatively expensive. However, with the improvement of living standards, the increase of various high-quality residential districts, and the increase of product scale and subdivision types, prices have gradually become civilians. At the same time, it adopts high-performance design, far exceeding the national first-class energy efficiency, and 360o DC variable frequency drive, which is truly energy-saving and electricity-saving. Consumers can choose models according to their budget and requirements.
At present, in agriculture, food, chemicals, ceramics, medicine, mineral processing, pulp and paper, wood processing and other industries, drying is almost required in all production processes. The quality of dried materials depends on whether they are well controlled and constant. temperature. The heat pump drying technology is a gentle and close to natural drying method, which is more suitable for the drying of most heat-sensitive materials such as agricultural products and medicinal materials.
Air source heat pump can realize refrigeration, floor heating, provide domestic hot water, and realize multiple functions of one machine. Compared with traditional air conditioning and floor heating systems, it has the following remarkable features and advantages: clean and environmentally friendly; one machine with multiple uses; low noise; Stable performance, long operating life; all built-in options, easy installation, more beautiful, more stable operation; super domestic hot water function. Although the air source heat pump has many advantages, its maintenance cannot be ignored.
