An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil spiral or helix. They are used in electrical engineering in applications where electric currents interact with magnetic fields in devices such as electric motors generators inductors electromagnets transformers solenoid valves and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field or conversely an external time-varying magnetic field through the interior of the coil generates an emf voltage in the conductor. In refrigeration the condenser coil dispels hot air to the outside of the space. The refrigerant then loops back to the compressor gets cold again absorbs heat and disperses it to the outside. As long as the compressor is running the refrigerant keeps up this continuous loop. Extracting heat from the space and transferring it to the refrigerant is the function of the evaporator coil . An evaporator is a device used in a process to turn the liquid form of a chemical substance such as water into its gaseous form vapor . The liquid is evaporated or vaporized into a gas form of the targeted substance in that process. One kind of evaporator is a kind of radiator coil used in a closed compressor driven circulation of a liquid coolant. That is called an air-conditioning system a c or refrigeration system allowing a compressed cooling chemical such as r-22 coolant or r-410a to evaporate vaporize from liquid to gas within the system...
