As shown, the improvement of flooded evaporation at CO2 moves about 10-12% which can be equivalent of 0,6 – 0,8K in decreasing in DT1 or increasing in evaporation temperature. This improvement can also be higher if the evaporator is constructed directly to flooded system or/and by applying forced (pump) recirculation.
2 acts as a volatile fluid in the evaporators (flooded system (1-6)) CO . (HFI) or by direct expansion into the evaporator (e.g. with an electronic expansion valve type ICM, and a cascade . 2 in Industrial Refrigeration Systems The air temperature is constantly measured and
They are : (1) dry expansion evaporator, also called direct expansion or D-X-evaporators, and (2) of flooded evaporators. D-X-evaporators are used in the vast majority of comfort air conditioning systems below 100 tons of cooling capacity. They are also used on some refrigeration and industrial process cooling equipment.
Differentiate direct-expansion, gravity flooded, and liquid overfeed evaporator arrangements 4. Describe the difference between single stage and two stage compression systems 6 During this presentation, we will discuss •Ammonia and its uses •Ammonia as a refrigerant •Ammonia refrigeration, the technology –Single stage: DX, flooded, overfeed
Such systems are usually called "flooded" because the outlet from the evaporator is a mix of gas and liquid in contrast to the typical DX system where the outlet is superheated. However, the terms "DX" and "flooded" are not opposites; it is not uncommon to have a direct expansion system that uses flooded evaporators.
