What is teperature drop across evaporator?

The temperature drop across an evaporator refers to the difference in temperature between the refrigerant entering the evaporator and the refrigerant leaving it. This drop occurs as the refrigerant absorbs heat from the surrounding environment, causing it to evaporate and change from a liquid to a gas. The magnitude of this temperature drop is crucial for the efficiency of refrigeration systems, as it influences the heat transfer process and overall system performance. Typically, this drop can range from a few degrees to several tens of degrees Fahrenheit or Celsius, depending on the system design and operating conditions.
