Electronic expansion valve. In this video we'll be covering EEV electronic expansion valve to learn how they work and where they are used. We learn basic refrigeration cycle, compressor, condenser, evaporator and different types of expansion valves.
Correction:
06:15 The bulb refrigerant expands to *OPEN* the valve, not close the valve. Letting more refrigerant in.
06:22 *CLOSE* the valve, not open the valve
