【正文】 s you may have seen this as water dripping from the bottom of your vehicle. Rest assured this is perfectly normal. The ideal temperature of the evaporator is 0℃ . Refrigerant enter the bottom of the evaporator as a low pressure liquid. The warn air passing through the evaporator fins causes the refrigerant to boil. As the refrigerant begins to boil, it can absorb large amounts of heat. This heat is then carried off with the refrigerant to the outside of the vehicle. Several other ponents work in conjunction with the evaporator. As mentioned above, the ideal temperature for an evaporator coil is 0℃ . Temperature and pressure regulating devices must be used to control its temperature. While there are many variations of devices used, their main functions are the same。 keeping pressure in the evaporator low and keeping the evaporator from freezing。 a frozen evaporator coil will not absorb as much heat. Thermal expansion valve Another mon refrigerant regulator is the thermal expansion vale. This type of valve can sense both temperature and pressure, and is very efficient at regulating refrigerant flow to the evaporator. Several variations of this valve are monly found. Another example of a thermal expansion valve is Chrysler’s “H block” type. This type of valve is usually located at the firewall, between the evaporator inlet and outlet tubes and the liquid and suction lines. These types of valves, although efficient, have some disadvantage over orifice tube systems. Like orifice tubes these valves can bee clogged with debris, but also have small moving parting that may stick and malfunction due to corrosion. Receiverdrier The receiverdrier, shown in , is used on the high side of systems that use a thermal expansion valve. This type of the metering valve requires liquid refrigerant. To ensure that the valve gets liquid refrigerant, a receiver is used. The primary function of the receiverdrier is to separate gas and liquid. The secondary purpose is to remove moisture and filter out dirt. The receiverdrier usually has a sight glass in the top. This sight glass is often used to charge the system. Under normal operating conditions, vapor bubble should not be visible in the sight glass. The use of the sight glass to charge the system is not remended in R134a systems as cloudiness and oil that has separated from the refrigerant can be mistake for bubbles. This type of mistake can lead to a dangerous overcharged condition. There are variations of receiverdriers and several different desiccant materials are in use. Some of the moisture removing desiccants found within are not patible with R134a. The desiccant type is usually identified on a sticker that is affixed to the receiverdrier. Newer receiverdrier use desiccant type XH7 and are patible with both R12 and R134a refrigerants. 備注： 英文原文出處包括出版社、出版時(shí)間、期刊的刊名、刊號(hào)、刊期。 電腦打印，用 A4 紙；中文譯名用小 二 號(hào)宋體加粗，正文用 小 四 號(hào)宋體，行距 固定值 20 磅 ，其他用小 四 號(hào)宋體。 頁(yè)邊距左邊 ，右邊 ,上下邊距 。 英文翻譯在左邊裝訂。 附上英文原文，用 A4 紙。
