摘要： PROBLEM TO BE SOLVED: To provide sufficiently high cooling capability by making use of air pole exhaust gas expanded by an expander in an air conditioning system for a fuel cell automobile. SOLUTION: The expander (23) is connected with a fuel cell (70) to expand the air pole off gas with the expander (23). During an expansion process of the expander (23), temperature of the air pole off gas lowers, and vapor in the air pole off gas is condensed to generate condensed water. The lower temperature air pole off gas after being expanded and the condensed water generated by the expander (23) are supplied to a vapor cooling heat exchanger (14). The air supplied into a cabin (80) is also introduced into the vapor cooling heat exchanger (14). The air pole off gas absorbs heat from the supplied air and temperature rises in the vapor cooling heat exchanger (14), and the condensed water absorbs heat from the supplied air to be evaporated. The supplied air cooled by the vapor cooling heat exchanger (14) is sent into the cabin (80). COPYRIGHT: (C)2004,JPO

摘要： An air-conditioning apparatus including refrigerant circuit (20) for performing of vapor compression type refrigeration cycle and suction rotor (31) provided with an adsorbent. The refrigerant circuit (20) is provided with preheating exchanger (33) for preheating any regeneration air for the suction rotor (31) by the residual heat of refrigerant radiated from indoor heat exchanger (23) and provided with heating exchanger (32) for heating the preheated regeneration air by the refrigerant discharged from compressor (21). Accordingly, as the regeneration air flowing toward the suction rotor (31) is satisfactorily heated, the regenerative capacity of the adsorbent can be enhanced.

摘要： An object of the present invention is to make it possible to impart an adequate degree of subcooling to the refrigerant that has passed through the first expansion mechanism, and to maintain the proper degree of superheating of the refrigerant sucked into the compressor in a refrigerant circuit that is provided with a two-stage expansion mechanism. The refrigeration device (1) of the present invention is provided with a compression mechanism (11), a radiator (14), a first expansion mechanism (16), a second expansion mechanism (20), an evaporator (31), a first internal heat exchanger (15), a branch pipe (4), a third expansion mechanism (19), and a second internal heat exchanger (18). The first internal heat exchanger causes heat to be exchanged between refrigerant that flows from the exit side of the radiator to the inflow side of the first expansion mechanism, and refrigerant that flows from the exit side of the evaporator to the refrigerant inflow side of the compression mechanism. The branch pipe branches from a third refrigerant pipe for connecting the exit side of the radiator and the refrigerant inflow side of the second expansion mechanism, and merges with the second refrigerant pipe. A third expansion mechanism is provided to the branch pipe. The second internal heat exchanger causes heat to be exchanged between refrigerant that flows out from the first expansion mechanism, and refrigerant that flows out from the third expansion mechanism.

摘要： PROBLEM TO BE SOLVED: To prevent instability in controlling a refrigerant outlet temperature of an indoor heat exchanger 27 to fluctuation of high pressure Pg, in an air conditioner having a refrigerant circuit 20 performing a supercritical refrigerating cycle, and an adjustment section 38 for adjusting the heat exchange amount of the indoor heat exchanger 27 in heating by changing an opening of an indoor expansion valve 26 on the basis of a target value in the indoor heat exchanger 27. SOLUTION: The adjustment section 38 is provided with a determining section 43 for determining the fluctuation of high-pressure pressure Pg occurring in the refrigerant circuit 20 is in a first condition by an opening changing motion of the indoor expansion valve 26 or a second condition free from the opening changing motion, and a correcting section 40 performing correcting motion to correct the target value to keep the heat exchange amount of the indoor heat exchanger 27 before and after the fluctuation of high-pressure pressure Pg constant or almost constant, in a case when the determining section 43 determines the second condition.
