    摘要: An illumination apparatus including: a power supply circuit which outputs a DC power obtained by rectifying an AC voltage and stepping up the rectified voltage; a light source unit having semiconductor light emitting elements turned on by the DC power; and a housing formed of a conductive material that is grounded through a ground path and on which the power supply circuit and the light source unit are mounted. When one of power feed lines is cut off, the light emitting elements are supplied with an AC power from an AC power source through the ground path and a stray capacitance formed between the light source unit and the housing, and a forward voltage of the light emitting elements has a light emission level hardly recognizable.

    摘要: An air-conditioning apparatus uses a zeotropic refrigerant mixture, in which its saturated liquid refrigerant temperature is lower than the saturated gas refrigerant temperature under the same pressure condition, as the heat source side refrigerant. When one or some of a plurality of heat exchangers related to heat medium functions as an evaporator, the air-conditioning apparatus executes an anti-freezing control that prevents the heat medium from freezing by estimating occurrence of freezing of the heat medium on the basis of a value obtained by subtracting a freezing temperature correction value that is set as a positive value larger than zero from an evaporating temperature of the refrigerant in the heat exchanger related to heat medium.
