Página 3 de 12 Energy efficiency ratio(EER): An equipment efficiency rating that is determined by dividing the output in Btuh by the input in watts. This does not take into account the startup and shutdown for each cycle. Evacuation: The removal of any gases not characteristic to a system or vessel. Evaporation: The condition that occurs when heat is absorbed by liquid and it changes to vapor. Evaporator: The component is a refrigeration system that absorbs heat into the system and evaporates the liquid refrigerant. Evaporator fan: A forced convector used to improve the efficiency of an evaporator by air movement over the coil. Expansion(meterting)device: The component between the high pressure liquid line and the evaporator that feeds the liquid refrigerant into the evaporator. Fan: A device that produces a pressure difference in air to move it. Fan relay coil: A magnetic coil that controls the starting and stopping of the fan. Filter: A fine mesh or porous material that removes particles from passing fluids. Freeze-up: Excess ice or frost accumulation on an evaporator to the point that air flow may be effected. |
