History of Refrigeration

For centuries,people have known that the evaporation of water produces a cooling effect. At first, they did not attempt to recognize and understand the phenomenon, but they knew that any portion of the body that became wet felt cold as it dried in the air. At least as early as the second century evaporation was used in Egypt to chill jars of water,and it was employed in ancient India to make ice(Neuberger,1930).(幾個(gè)世紀以來(lái),人們已經(jīng)認識到水蒸發(fā)可以產(chǎn)生冷卻效果。起初,人們沒(méi)有試圖去認知和理解這種現象,但人們知道身體的任一潮濕部分在空氣中晾曬時(shí)會(huì )有冷的感覺(jué)。至少早在二世紀,蒸發(fā)在埃及被用來(lái)冷卻壇裝的水,在古印度被用來(lái)制冰(Neuberger,1930)。)

The first attempts to produce refrigeration mechanically depended on the cooling effects of the evaporation of water. In 1755 William Cullen, a Scottish physician, obtained sufficiently low temperatures for ice making. He accomplished this by reducing the pressure on water in a closed container with an air pump. At a very low pressure the liquid evaporated or boiled at a low temperature. The heat required for a portion of water to change phase from liquid to vapor was taken from the rest of the water, and at least part of the water remaining turned to ice. Since Cullen, many engineers and scientists have created a number of inventions for clarifying the main principles of mechanical refrigeration (Goosman, 1924). In 1834, Jacob Perkins, an American residing in England, constructed and patented a vapor-compression machine with a compressor, a condenser, an evaporator, and a cock between the condenser and the evaporator (Critchell and Raymond, 1912). He made it by evaporating under reduced pressure a volatile fluid obtained by the destructive distillation of India rubber. It was used to produce a small quantity of ice, but not commercially. Growing demand over the 30 years after 1850 brought great inventive accomplishments and progress. New substances, e.g ammonia and carbon dioxide, which were more suitable than water and ether, were made available by Faraday, Thilorier, and others, and they demonstrated that these substances could be liquefied.(機械制冷的第一次嘗試依賴(lài)于水蒸發(fā)產(chǎn)生的冷卻效果。1755年,蘇格蘭醫師William Cullen得到了足夠低的溫度用于制冰。他利用一個(gè)空氣泵來(lái)降低一個(gè)封閉容器內水面上的壓力來(lái)達到這個(gè)目的。在相當低的壓力下,液體可在低溫下蒸發(fā)或沸騰。一部分水從液態(tài)到汽態(tài)發(fā)生相變所需要的熱量來(lái)自余下的水,至少剩余的部分水會(huì )變成冰。從Cullen開(kāi)始,許多工程師和科學(xué)家創(chuàng )造了大量的發(fā)明來(lái)闡釋機械制冷的原理(Goosman,1924)。1834年,定居英格蘭的美國人Jacob Perkins造出了一臺由壓縮機、冷凝器、蒸發(fā)器和位于冷凝器和蒸發(fā)器之間的開(kāi)關(guān)組成的蒸汽壓縮式制冷機,并取得了專(zhuān)利(Critchell and Raymond,1912)。他是通過(guò)在減壓下蒸發(fā)一種易揮發(fā)的流體實(shí)現的,該流體是通過(guò)一種印度橡膠干餾得到的。它被用于少量冰的生產(chǎn),但未被商業(yè)化。1850年后30多年的增長(cháng)需要帶來(lái)了巨大的創(chuàng )造性的成果和進(jìn)展。比水和乙醚更適合的新工質(zhì)被Faraday,Thilorier等人發(fā)現,如氨和二氧化碳,他們證明了這些物質(zhì)可被液化。)

The theoretical background required for mechanical refrigeration was provided by Rumford and Davy, who had explained the nature of heat, and by Kelvin, Joule, and Rankine, who were continuing the work begun by Sadi Carnot informulating the science of thermodynamics(Travers,1946). Refrigerating machines appeared between 1850 and 1880, and these could be classified according to substance (refrigerant). Machines using air as a refrigerant were called compressed-air or cold-air machines and played a significant role in refrigeration history.Dr.John Gorrie, an American, developed a real commercial cold-air machine and patented it in England in 1950 and in America in 1951(DOI,1952).(Rumford、Davy、Kelvin、Joule和Rankine提供了機械制冷所需要的理論背景,Rumford和Davy解釋了熱的本質(zhì),Kelvin、Joule和Rankine延續了Sadi Carnot的工作,明確的對熱力學(xué)進(jìn)行了闡述(Travers,1946)。制冷機出現在1850至1880年之間,并可以依據工質(zhì)(制冷劑)分類(lèi)。用空氣作為制冷劑的制冷機,稱(chēng)為壓縮空氣機或冷空氣制冷機,并在制冷史上起著(zhù)重要的作用。美國人John Gorrie博士,開(kāi)發(fā)了一種真正商用的冷空氣制冷機,并于1950年在英格蘭,1951年在美國獲得專(zhuān)利(DOI,1952)。)

Refrigerating machines using cold air as a refrigerant were divided into two types, closed cycle and open cycle.In the closed cycle,air confined to the machine at a pressure higher than the atmospheric pressure was utilized repeatedly during the operation. In the open cycle, air was drawn into the machine at atmospheric pressure and when cooled was discharged directly into the space to be refrigerated.In Europe.Dr.Alexander C.Kirk commercially developed a closed cycle refrigerating machine in 1862, and Franz Windhausen invented a closed cycle machine and patented it in America in 1870. The open cycle refrigerating machines theoretically outlined by Kelvin and Rankine in the early 1850s were invented by a Frenchman, Paul Giffard, in 1873 and by Joseph J.Colemanand James Bellin Britain in 1877(Roelker,1906).(用冷空氣作制冷劑的制冷機可分為兩類(lèi):閉合循環(huán)和開(kāi)式循環(huán)。在閉合循環(huán)中,進(jìn)入制冷機的高于大氣壓的空氣在工作中可被重復利用。在開(kāi)口循環(huán)中,空氣在大氣壓下進(jìn)入制冷機,被冷卻后,直接排放到需要制冷的空間。在歐洲,1862年Alexander C. Kirk博士開(kāi)發(fā)了一種商業(yè)用閉合循環(huán)制冷機,Franz Windhausen發(fā)明了一種閉合循環(huán)制冷機并于1870年在美國獲得專(zhuān)利。在19世紀50年代早期,Kelvin和Rankine在理論上構件了開(kāi)口循環(huán)制冷機的輪廓,法國人Paul Giffard于1873年,Joseph J. Coleman和James Bell在英國于1877年,發(fā)明了開(kāi)口循環(huán)制冷機(Roelker,1906)。)

In 1860, a French engineer, Ferdinand P. Edniond Carre, invented an intermittent crude ammonia absorption apparatus based on the chemical affinity of ammonia for water, which produced ice on a limited scale. Despite its limitations, it represented significant progress.(1860年,法國工程師Ferdin and P .Edniond Carre基于氨和水的化學(xué)新和力,發(fā)明了一種間歇式氨吸收制冷裝置,用于小規模制冰。盡管具有局限性,但體現了很大的進(jìn)步。)

His apparatus had a hand pump and could freeze a small amount of water in about 5 minutes(Goosman, 1924). It was widely used in Paris for a while, but it suffered from a serious disadvantage in that the sulfuric acid quickly became diluted with water and lost its affinity. (他的裝置有一個(gè)手壓泵,能夠在大約5分鐘內使少量的水結冰(Goosman,1924)。它在巴黎廣泛應用了一段時(shí)間,但它有一個(gè)嚴重的缺點(diǎn),就是硫酸遇水會(huì )迅速變稀,失去其親和力。)

The real inventor of a small, hand-operated absorption machine was H.A. Fleuss, who designed an effective pump for this machine. A comparatively large-scale ice making absorption unit was constructed in 1878 by F. Windhausen. It operated continuously by drawing water from sulfuric acid with additional heat to increase the affinity(Goosman,1924).(小型手動(dòng)吸收式制冷機的真正發(fā)明者是H.A.Fleuss,他為該制冷機設計了高效的泵。F.Windhausen于1878年,制成了規模相當大的吸收式制冰機。它通過(guò)加熱硫酸的方式提高硫酸的濃度來(lái)連續工作(Goosman,1924)。)

One of the earliest of the vapor-compression machines was invented and patented by an American professor, Alexander C. Twining,in 1853.He established an ice production plant using this system in Cleveland, Ohio and could produce close to a ton per day. After that, a number of other inventors experimented with vapor-compression machines which used ether or its compounds (Woolrich, 1947). In France F.P.E. Carre developed and installed an ether-compression machine, and Charles Tellier (who was a versatile pioneer of mechanical refrigeration) constructed a plant using methyl ether as a refrigerant. In Germany Carl Linde,financed by brewers, established a methyl ether unit in 1874.Just before this Linde had paved the way for great improvements in refrigerating machinery by demonstrating how its thermodynamic efficiency could be calculated and increased (Goosman, 1924). (最早的蒸氣壓縮式制冷機之一是由美國教授A(yíng)lexander C. Twining于1853年發(fā)明的,并獲得專(zhuān)利。他利用該系統在Cleveland,Ohio建成了一個(gè)制冰廠(chǎng),日產(chǎn)冰量接近1噸。自那之后,大量的發(fā)明家用以醚及其化合物為工質(zhì)的蒸汽壓縮式制冷機進(jìn)行試驗(Woolrich,1947)。在法國,F.P.E.Carre開(kāi)發(fā)并安裝了一臺乙醚為工質(zhì)的壓縮式制冷機,Charles Tellier(多才多藝的機械制冷先驅者)用甲醚作為制冷劑構件了一臺裝置。在德國Carl Linde,由釀酒者提供資金于1874年建成了一個(gè)甲醚制冷裝置。僅僅在此之前,Linde已通過(guò)證明如何計算和提高制冷機的熱力學(xué)效率,為制冷機的巨大發(fā)展鋪平了道路(Goosman,1924)。)

Inventors of compression machines also experimented with ammonia, which became the most popular refrigerant and was used widely for many years.In the 1860s Tellier developed an ammonia-compression machine.In 1872 David Boyle made satisfactory equipment for ice making and patented it in 1872 in America.Nevertheless, the most important figure in the development of ammonia-compression machines was Linde, who obtained a patent in 1876 for one which was installed in Trieste brewery the following year. Later, Linde's model became very popular and was considered excellent in its mechanical details (Awberry, 1942). The use of ammonia in the compression refrigerating machines was a significant step forward. In addition to its thermodynamic advantage, the pressures it required were easy to produce, and machines which used it could be small in size. In the late 1860s, P.H. Van der Weyde of Philadelphia got a patent for a compression unit which featured a refrigerant composed of petroleum products (Goosman, 1924). In 1875 R.P. Pictet at the University of Genevaint roduced a compression machine that used sulfuric acid.In 1866 T.S.C.Lowe, an American, developed refrigerating equipment that used carbon dioxide. Carbon dioxide compression machines became important, because of the gas's harmlesness, in installations where safety was the primary concern,although they were not used extensively until the 1890s(Awberry,1942). Between 1880 and 1890 ammonia-compression installations became more common. By 1890 mechanical refrigeration had proved to be both practical and economical for the food refrigeration industry.Europeans provided most of the theoretical background for the development of mechanical refrigeration, but Americans participated vigorously in the wide spread inventive activity between 1850 and 1880.(壓縮制冷機的發(fā)明者們,也曾用最流行的、并被廣泛應用多年的制冷劑氨做過(guò)試驗。在19世紀60年代,Tellier開(kāi)發(fā)了一臺氨壓縮制冷機。在1872年,David Boyle制成了令人滿(mǎn)意的制冷裝置,并于1872年在美國申請專(zhuān)利。然而,在氨壓縮制冷機的發(fā)展過(guò)程中最重要的人物是Linde,他于1876年獲得專(zhuān)利并在第二年安裝在Trieste的釀酒廠(chǎng)。后來(lái),Linde的模型變的非常流行,從機械方面說(shuō)它被認為是最完美的(Awberry,1942)。氨在壓縮式制冷機中的應用是重要的進(jìn)步。除了其熱力學(xué)優(yōu)點(diǎn)外,它所需要的壓力容易達到,應用它的機器在體積上可以很小。在19世紀60年代晚期,費城的P.H.Vander Weyde獲得了一項壓縮式制冷機的專(zhuān)利,該壓縮機的特點(diǎn)是以由石油產(chǎn)品構成的混合物作為制冷劑(Goosman,1924)。1875年,日內瓦大學(xué)的R.P.Pictet引進(jìn)了一臺使用硫酸的壓縮式制冷機。1866年,美國人T.S.C.Lowe開(kāi)發(fā)了使用二氧化碳的制冷裝置。二氧化碳壓縮式制冷機,盡管在19世紀90年代以前未得到廣泛應用,但因該氣體的無(wú)害性,它在安全是首要關(guān)心問(wèn)題的安裝中變得非常重要(Awberry,1942)。在1880至1890年間,氨壓縮機的安裝變得更加普遍。到1890年,在食品制冷行業(yè)機械制冷已被證實(shí)是既可行又經(jīng)濟的。歐洲人為機械制冷的發(fā)展提供了大部分的理論背景,而美國人在1850到1880年間卻把更多的精力投入到廣泛的發(fā)明創(chuàng )造活動(dòng)中。)

Steady technical progress in the field of mechanical refrigeration marked the years after 1890.Revolutionary changes were not the rule,but many improvements were made,inseveral countries,in the design and construction of refrigerating units, as well as in their basic components,compressors,condensers,and evaporators.(在機械制冷領(lǐng)域,平穩的技術(shù)進(jìn)步是在1890年后。革命性的變化不是主要的,但在許多國家,制冷裝置的設計與構造取得了很大的進(jìn)步。它們的基本部件、壓縮機、冷凝器和蒸發(fā)器也取得了很大的進(jìn)步。)
