  • 蒸發器是工作的步驟

蒸發器主要是由加熱室和蒸發室兩個部分組成的。加熱室主要是負責向液體提供蒸發的熱量,來促使液體沸騰汽化。蒸發室主要是負責讓氣體和液體兩項完全分離出來。蒸發器是制冷四大件中很重要的一個部件,低溫的冷凝液體通過蒸發器,與外界的空氣進行熱交換,氣化吸熱,達到制冷的效果。
蒸發器的主要工作步驟:
1.液體冷媒通過送料口進入,同時加熱蒸汽對加熱室內部的加熱管束進行加熱,加熱室內中間的較粗的管子由于受熱面積不如加熱管束面積大,故加熱管束汽化的冷媒上升進入蒸發室。
2.而中央循環管的液體冷媒下降,繼續進行循環。(中央循環管的橫截面積約為加熱管束總橫截面積的40%-100%左右,這也直接影響到了蒸發器的效率) 蒸發器在新風換熱機組、風機盤管中的應用主要是在制冷過程中提供冷水,在制熱過程中提供加熱后的冷媒。
3.它在地源熱泵系統中的應用于冷凝器相反,在地源熱泵機組進行供熱過程中,蒸發器屬于地源側設備,對地源側的循環水進行加熱,再通過機組換熱,將熱水傳至冷凝器,由冷凝器將熱水中的熱量排放出去。
4.在機組進行制冷過程中,蒸發器屬于末端設備,由地源側的冷凝器對地源側水進行冷凝,并供給蒸發器對外吸熱,從而達到對外界制冷的效果

男人女人做刺激性视频The evaporator is mainly composed of heating chamber and evaporation chamber. The heating chamber is mainly responsible for providing the evaporation heat to the liquid to make the liquid boil and vaporize. The evaporation chamber is mainly responsible for the complete separation of gas and liquid. Evaporator is one of the four important parts of refrigeration. The low-temperature condensed liquid exchanges heat with the outside air through the evaporator, vaporizes and absorbs heat to achieve the refrigeration effect.            Main working steps of evaporator:            1. The liquid refrigerant enters through the feeding port, and the heating steam heats the heating tube bundle inside the heating chamber. Because the heating area of the coarser tube in the middle of the heating chamber is not as large as that of the heating tube bundle, the vaporized refrigerant of the heating tube bundle rises into the evaporation chamber.            2. The liquid refrigerant in the central circulation pipe drops and continues to circulate. (the cross-sectional area of the central circulation pipe is about 40% - 100% of the total cross-sectional area of the heating tube bundle, which also directly affects the efficiency of the evaporator). The application of the evaporator in the fresh air heat exchange unit and fan coil is mainly to provide cold water in the refrigeration process and the heated refrigerant in the heating process.            3. Its application in the ground source heat pump system is opposite to that in the condenser. In the heating process of the ground source heat pump unit, the evaporator belongs to the equipment on the ground source side, which heats the circulating water on the ground source side, and then transfers the hot water to the condenser through the heat exchange of the unit, which discharges the heat in the hot water.            4. In the refrigeration process of the unit, the evaporator belongs to the terminal equipment. The condenser at the ground source side condenses the water at the ground source side and supplies the evaporator with external heat absorption, so as to achieve the effect of external refrigeration.
