WebThis method allows regulating the mass flow rate of the refrigerant passing through the evaporator. The use of the hot gas bypass valve in a transcritical cooling system with a medium temperature (MT) evaporator and an internal heat exchanger (IHX) is shown in Figure 2. Figure 2. WebAn evaporator that covers the coils being cooled with liquid refrigerant is a: Flooded evaporator. As a mixture travels through an evaporator, the liquid percentage: Decreases. Chillers can be classified as: Flooded or direct expansion. Commercial refrigeration equipment for dry storage typically uses: High-temperature evaporators.

Evaporators work using the same principle design. A heat source is in contact with the liquid causing it to evaporate. The vapor is removed entirely (like in cooking), or it is stored for reuse (like in a refrigerator) or a product for isolation (essential oil). Rotary evaporators use a vacuum pump to create a low pressure over a solve…
