摘要:
A refrigerant circuit (40) is provided with an outdoor heat exchanger (54) and an indoor heat exchanger (55), and besides these, it is provided with two adsorption heat exchangers (56, 57). The indoor heat exchanger (55) and two adsorption heat exchangers (56, 57) are installed in an indoor unit (11), and the outdoor heat exchanger (54) is installed in an outdoor unit (12). In the adsorption heat exchangers (56, 57) becoming evaporators, the moisture in the air is adsorbed by an adsorbent. In the adsorption heat exchangers (56, 57) becoming condensers, moisture is desorbed from the adsorbent and imparted to the air. The air dehumidified or humidified by the adsorption heat exchangers (56, 57) is supplied into a room and the latent heat load in the room is processed. On the other hand, in the indoor heat exchanger (55), the cooling or heating of air is effected. The air cooled or heated by the indoor heat exchanger (55) is supplied to the room and the sensible heat load in the room is processed.

The coolant circuit (50) comprises a compressor (53), a first adsorption heat exchanger (51) with an adsorbent supported thereon, an opening variable expansion valve (55), and a second adsorption heat exchanger (52) with an adsorbent supported thereon. A first batch operation in which moisture in the air is adsorbed in the second adsorption heat exchanger (52) while moisture is released into the air in the first adsorption heat exchanger (51), and a second batch operation in which moisture in the air is adsorbed in the first adsorption heat exchanger (51) while moisture is released into the air in the second adsorption heat exchanger (52), are alternately carried out to supply humidity conditioned air into a room. The opening of the expansion valve (55) is controlled so that, upon the elapse of the valve control start time after a predetermined time from the start of each batch operation, the degree of superheat of the coolant in the coolant circuit (50) is brought to a predetermined value.
摘要:
An apparatus for producing hydrogen gas from a hydrocarbon original fuel, oxygen and steam, which comprises a fuel reformer (5) packed with a catalyst (27) having activity for a partial oxidation of the original fuel, and effects the partial oxidation of the original fuel with the aid of the catalyst (27) and then forms hydrogen through the water-gas-shift reaction using the CO gas generated by the partial oxidation reaction as a reactant, wherein the original fuel, oxygen and steam are fed to the fuel reformer (5) in such amounts that a mole ratio of the oxygen to the carbon in the original fuel (O2/C) is 0.9 times the stoichiometric O2/C ratio in the partial oxidation reaction or more and a mole ratio of the steam to the carbon in the original fuel (H2O/C) is 0.5 or more. The fuel reformer (5) is excellent as a modifier for a fuel cell since it reduces the external heat required and also lowers the CO concentration in the resultant modified gas. Further, the fuel reformer (5) can utilize the discharge gas from an oxygen electrode of a fuel cell as oxygen and steam to be used therein.

Thus, thee modification device has a reforming part (6) being reduced in the nonuniformity of temperature, exhibits improved heat efficiency and has a simple and compact structure.

摘要:
A humidity control system (10) includes a refrigerant circuit (50) to which two adsorption heat exchangers (51, 52) are connected. In the humidity control system (10), air is humidified in the adsorption heat exchanger (51, 52) working as the condenser while air is dehumidified in the adsorption heat exchanger (51, 52) working as the evaporator. If during the dehumidification operation the actually measured value of the room temperature is lower than the selected value of the room temperature or if during the humidification operation the actually measured value of the room temperature is higher than the selected value of the room temperature, the performance of a compressor (53) is controlled such that the actually measured value of the room temperature equals the selected value of the room temperature.
