Cooling apparatus, light source apparatus including cooling apparatus, and projection-type image display apparatus including light source apparatus

An electronic apparatus comprising:

• a cooling apparatus comprising
• a refrigerant circuit in which a compressor, a condenser, an expansion valve and an evaporator are circularly connected sequentially, via a pipe, and refrigerant circulates, and
• a heater provided to the refrigerant circuit;
• and
• a controller configured to control at least the heater of the cooling apparatus,
• the evaporator being thermally connected to an exothermic element,
• the heater comprising heaters provided between the evaporator and a suction side of the compressor, and between the evaporator and the expansion valve, respectively,
• the controller being configured to
• control the heater to keep a temperature of the evaporator to be higher than a dew point,
• control the heater provided between the evaporator and the expansion valve, to adjust a quality of refrigerant in a two-phase state, and
• control the heater provided between the evaporator and the suction side of the compressor, to turn refrigerant to be sucked into the compressor into the vapor state.
