Refrigeration, in essence, transfers heat from any medium that can store heat to the outside, so that the temperature of the medium is lowered and the effect of refrigeration is obtained. Common refrigeration equipment includes: benchtop freeze dryer&©|8203;, cooling tower, water cooler, screw chiller, industrial chiller, air conditioner chiller, constant temperature and humidity air conditioner, low temperature chiller, etc. Refrigeration equipment covers all corners of industry, agriculture, commerce, food, and aquaculture, and is widely used. Refrigeration equipment is the temperature and humidity control equipment.
ˇˇˇˇFirst, the refrigeration technology overview:
ˇˇˇˇThe transition from natural sources such as natural ice to artificial refrigeration is the initial stage of the development of refrigeration technology. In 1777, Nairne E. Gerale's integrated sulfuric acid integrated refrigeration system.
ˇˇˇˇWater-absorbent ice-making test; in 1810, J. Leslie's sulfuric acid-water absorption ice-making device; in 1859, F. Carre was made into an ammonia-water absorption refrigerator, and was applied in 1860. C. Munters and B. Von Plate were made into ammonia-water-hydrogen diffusion absorption refrigerators, which were obtained in 1920. In the mid-20th century, motor-driven compression chillers dominated the conventional refrigeration sector. In the past 30 years, absorption refrigeration and heat pump technology have entered a stage of vigorous development. The research and analysis project on adsorption refrigeration included in the European Community's JOULE plan in the 1990s made the adsorption refrigeration research reach a new climax.
ˇˇˇˇSecond, the refrigeration system
ˇˇˇˇThe refrigeration system consists of four basic parts, namely a compressor, a condenser, a throttling component, and an evaporator. The four large pieces are connected by a copper tube into a closed system in a certain order, and the system is filled with a certain amount of refrigerant. The general air-conditioning re |
