Disclosed herein is a method of controlling a linear expansion valve of a cooling cycle apparatus. The method comprises a first step of calculating a target opening level value according to suction overheat level of compressors to control a linear expansion valve based on the calculated target opening level value, and a second step of calculating a new target opening level value according to the suction overheat level of the compressors and discharge temperature of the compressors to control the linear expansion valve based on the calculated new target opening level value. Consequently, the discharge temperature of the compressors is prevented from being excessively increased, and therefore, the compressors are prevented from being overheated and damaged, and reliability of the cooling cycle apparatus is improved.

Disclosed herein is a cooling/heating apparatus using waste heat from a fuel cell. The cooling/heating apparatus comprises a fuel cell, a hydrogen modifying unit, a cooling/heating unit, and refrigerant heating units. The cooling/heating unit includes at least one compressor, a four-way valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, to establish a heat pump type refrigerant cycle. The refrigerant heating units provide waste heat recovered from the fuel cell and the hydrogen modifying unit to a suction-side refrigerant line connected to the suction side of the compressor included in the cooling/heating unit to raise the temperature of a refrigerant. During a heating operation, the cooling/heating apparatus can achieve an enhancement in heating performance and an enhancement in system efficiency.
