An evaporator is a type of heat exchanger device that facilitates evaporation by utilizing conductive and convective heat transfer, which provides the necessary thermal energy for phase transition from liquid to vapour. Within evaporators, a circulating liquid is exposed to an atmospheric or reduced pressure environment causing it to boil at a ...
The basic module of an evaporator is known as the “body” of the evaporator and refers to the calandria and the flash chamber. The term “effect” is used to describe the body where vapor is extracted from the raw material and is operating at the same boiling point.
To complete the refrigeration cycle, the refrigerant vapor from the evaporator is again a saturated vapor and is routed back into the compressor. Over time, the evaporator may collect ice or water from ambient humidity. The ice is melted through defrosting. The water from the melted ice or the evaporator then drips into a drip pan, and the ...
Vapor-compression refrigeration [6] For comparison, a simple stylized diagram of a heat pump's vapor-compression refrigeration cycle: 1) condenser, 2) expansion valve, 3) evaporator, 4) compressor (Note that this diagram is flipped vertically and horizontally compared to the previous one) [7] Temperature–entropy diagram of the vapor-compression cycle.
This usually means that the evaporator section of the HRSG will have to be split and the SCR placed in between the two sections. Some low-temperature NOx catalysts have recently [ when? ] come to market that allow for the SCR to be placed between the evaporator and economizer sections (350–500 °F [177–260 °C]).
The evaporator is the cold side of an air conditioner or heat pump. ... Sub cooling is the difference between its saturation temperature and the actual liquid ...
