Usage: commonly used in HVAC and refrigeration systems
2. a shallow pan or vessel used to evaporate liquid, such as water or sap, by heating
Usage: used in cooking, maple syrup production, and laboratory work

Examples

• The air conditioner's evaporator cools the indoor air by allowing refrigerant to evaporate.
• A maple syrup producer uses a large evaporator to boil down tree sap.
• The evaporator in the freezer removes heat from the compartment.
• Salt can be harvested by using an evaporator to remove water from seawater.
• The laboratory technician placed the solution in an evaporator to concentrate it.
• Modern refrigeration systems rely on efficient evaporators to maintain cold temperatures.
