    摘要: In a range of a wind velocity of 0.5 to 3.5 (m/s) in a refrigeration cycle, when combining absorbent having a small dependency on the wind velocity and the refrigeration cycle, it is not possible to vary dehumidification capability by changing the wind velocity and matching with an actual load is poor. In a refrigerating and air conditioning apparatus having a refrigerator 20 in which refrigerant is put, and having a compressor 20a for compressing the refrigerant, a condenser 20b, and a throttle device 20c, and an evaporator 20d, and a desiccant rotor 1, which is water adsorption means, an adsorbent is supported with the desiccant rotor 1, whose time constant at a water adsorption equilibrium becomes small as a wind velocity increases in the range of the wind velocity of 0.5 to 3.5 m/s, the condenser 20b is disposed upwind of the desiccant rotor 1, and the evaporator 20d is disposed downwind of the desiccant rotor 1.

    摘要: To obtain a refrigeration air conditioning system having a dehumidifying function by means of a moisture adsorption means, allowing the moisture adsorption means to be regenerated by use of discharged condensation heat or other discharged heat of a low temperature range in the refrigeration cycle, and exerting stable cooling performance even at a dry-bulb temperature of 0° C. or less.A desiccant rotor 1, being a moisture adsorption means, is made to hold an adsorbent having pore sizes of 5 μm or less, more preferably 20 nm or less, and furthermore preferably 1-1.4 nm in a space at a predetermined temperature range of a dry-bulb temperature of 0° C. or less. Forming of frost on an evaporator 20d is prevented by supplying the air dehumidified by the desiccant rotor 1 to the evaporator 20d disposed on the leeward side thereof in a freezing room as the desiccant rotor 1 is rotated, while the adsorbent having adsorbed moisture is made dried and made to recover its adsorbing ability by supplying the air dried by discharged heat from a condenser 20b disposed on the windward side thereof to the desiccant rotor 1 at the outside of the freezing room.

    摘要: A condenser (2), an electronic expansion valve (5), an evaporator (6), and a motorized suction throttle valve (8) are connected in series with a compressor. When a capacity is increased, the electronic expansion valve (5) is controlled to be in a throttling direction and the motorized suction throttle valve (8) is controlled to be in an unthrottling direction in association with the control of the electronic expansion valve (5), and when a capacity is decreased, the electronic expansion valve (5) is controlled to be in an unthrottling direction and the motorized suction throttle valve (8) is controlled to be in a throttling direction in association with the control of the electronic expansion valve (5). While a capacity control of a compressor by a throttle control is been carried out, such associated control is made between the electronic expansion valve (5) and the motorized suction throttle valve (8), realizing a fine temperature control in a refrigerating machine without hunting.
