有英文牛人幫忙翻譯一些資料嗎 感激不盡

【專家解說(shuō)】：-----7頁(yè)太多啦,你應(yīng)該去找專業(yè)的翻譯公司了-------- Heat pumps are devices that are primarily used for space heating and cooling applications. 熱泵是暖通空調(diào)器的主要設(shè)備. In the heating only mode, they have also been used for domestic hot water (DHW) and industrial process heat (IPH) applications. 在只供熱模式下,家用熱水器和工業(yè)取暖器都廣泛的用到熱泵(熱機(jī)). A heat pump typically operates between two temperature levels, pumping heat from a low temperature source (generally outdoor air for the space heating applications) to a sink or conditioned space being maintained at a higher temperature. 熱泵通常是運(yùn)行在兩個(gè)溫度水平上,即從一個(gè)低溫源(一般是空暖機(jī)從室外取得的空氣)壓縮增溫,并送到一個(gè)水槽或者受調(diào)節(jié)的空間里,以維持較高的溫度. The work required to pump a given quantity of heat energy decreases as the temperature difference between the sink and the source decreases. 這就要求,當(dāng)水槽和低溫源的溫差降低時(shí),壓縮機(jī)提供的熱能也能作出相應(yīng)的減少. This also explains the fact that single-stage heat pumps require large work input to pump heat as the outdoor air or sink temperature decreases, as it happens during severe winter conditions. 同時(shí)也表明,這種單相熱泵需要很大的工作輸入,以便在冬天里室外空氣或者水槽溫度下降的情況下壓熱. This makes the heat pump operation very inefficient, as reflected in the coefficient of performance (COP) of the heat pump approaching the theoretical limit of unity. 這導(dǎo)致熱泵工作效率極其低下,即表現(xiàn)為,熱泵的制冷系數(shù)降到了機(jī)組的理論限定值. This inherent thermodynamic effect related to magnitude of temperature lift is exploited to improve the heat pump COP by raising the source (low end) temperature through solar or ground or ground water coupling. 這種與溫升等級(jí)有關(guān)的熱力內(nèi)效率可用于提高熱泵的制冷系數(shù),即利用太陽(yáng)能或者地?zé)崮芑蛘叩叵滤詈咸岣邿嵩?低溫端)的溫度. In solar-assisted heat pumps (SAHP), the topic of present discussion, solar energy is harnessed in a solar collector at a temperature higher relative to the ambient temperature, and is utilized to vaporize the refrigerant in the heat pump evaporator. 在太陽(yáng)能輔助式熱泵中,當(dāng)今主要是,用一個(gè)太陽(yáng)能收集裝置從一個(gè)溫度較高的周圍環(huán)境里收集能量,用以汽化熱泵內(nèi)的制冷劑. This configuration is known as the indirect or conventional solar-assisted heat pump configuration. 這種布局即間接式或傳統(tǒng)的太陽(yáng)能輔助集熱系統(tǒng). In this configuration both solar collector and heat pump evaporator are separate units but coupled through a heat exchanger. 此系統(tǒng)中,太陽(yáng)能收集器和熱泵的汽化器是兩個(gè)單獨(dú)分開的裝置,并通過(guò)一個(gè)換熱器耦合. In a direct expansion heat pump, an alternative configuration, the solar collector also acts as the heat pump evaporator, thus reducing the number of components as well as inefficient thermodynamic processes across the two eliminated units. 在直接膨脹式熱泵中,即另一種布局下,太陽(yáng)能收集裝置兼作熱泵汽化器,這樣既減少了設(shè)備組件的數(shù)量,也減少了兩組件間的熱力傳送損耗. In direct expansion solar-assisted heat pump (DX-SAHP), liquid refrigerant from the condenser is flashed through a throttle valve into the tubes of the solar collector panel for vaporization and superheating of the refrigerant [1]. 直接膨脹式太陽(yáng)能輔助熱泵系統(tǒng)中,來(lái)自壓縮機(jī)內(nèi)的液態(tài)制冷劑流過(guò)節(jié)流閥,進(jìn)入太陽(yáng)能收集面板的熱管內(nèi),從而使得液態(tài)的制冷劑過(guò)熱和汽化.
