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.

A biodegradable filament nonwoven fabric comprising a nonwoven web made up of filaments, each filament comprising a high melting point component composed of a first aliphatic polyester having biodegradability and a low melting point component composed of a second aliphatic polyester having biodegradability with a melting point lower than that of the high melting point component, the nonwoven web processed to a predetermined nonwoven fabric configuration. At least one of the high melting point component and the low melting point component is arranged in a plurality of divisions within the cross section of the filament. Both the high melting point component and the low melting point component extend continuously in the axial direction of the filament and are exposed on the surface of the filament. A method for manufacturing the biodegradable filament nonwoven fabric is also disclosed herein.

A multiroom air conditioner has a plurality of indoor heat exchangers connected to a single outdoor heat exchanger. A reversible expansion valve is installed on a liquid-side branch pipe for each of the indoor heat exchangers, and a solenoid valve is installed on a gas-side branch pipe for each indoor heat exchanger. Temperature sensors are provided on the liquid-side branch pipes, on the gas-side branch pipes, and on the outlet side during cooling of the outdoor heat exchanger. A pressure sensor or a temperature sensor detects the saturation temperature on the high-pressure side of the compressor. Based on the saturation temperature on the high-pressure side of the compressor, the temperature on the outlet side during cooling of the outdoor heat exchanger, and the temperatures in the liquidside branch pipes, a controller controls the expansion valves so as to obtain a target degree of subcooling during cooling and heating. The controller can also control the expansion valves so that the temperatures in each of the branch pipes are approximately equal to one another.

A control device for refrigeration cycle constructed with a compressor, a condenser, an electrically operated expansion valve, an evaporator, and so forth, all being connected in series, wherein there are further provided a by-pass extending from an inlet or an outlet or both of the expansion valve upto an inlet of the compressor through a capillary tube; a first temperature sensor to sense a temperature of a cooling medium at the inlet of the compressor; a second temperature sensor to sense a temperature of the cooling medium within an intake tubing, through which the cooling medium is taken into the inlet of the compressor; and a control device which calculates a super-heat quantity of the cooling medium taken into the compressor on the basis of a difference between the detection outputs of the first and second temperature sensors, and controls a degree of opening of the electrically operated expansion valve, thereby enabling the refrigeration cycle to be operated at high efficiency and in an energy-saving mode.
摘要:
The cooling performance of an air conditioning apparatus is controlled by a selective combination of three methods of regulation, in accordance with the required degree of cooling. A first stage of regulation controls the volume of air delivered by a fan 6, a second stage controls the amount of refrigerant flowing through a pressure reduction means 7, and a third stage controls the amount of refrigerant circulating in a compressor feedback circuit 9. Any one of or combination of these three controls may be employed in accordance with the prevailing temperature condition and the required cooling performance.

A seat belt system including at least one seat belt which extends from one side of a seat to a point forward of the other side of the seat such that the seat belt extends obliquely forward from one side to the other of the seat, a tongue plate coupled to the seat belt and a buckle provided on the other side of the seat and for engagement with the tongue plate.
摘要:
A water-disintegrable sheet having biodegradability. The sheet comprises one or more kinds of biodegradable synthetic fibers, and one or more kinds of natural fibers and/or regenerated fibers, all the fibers being bound together by a binder such that the binding power of the binder will be substantially lost in water. The sheet has a given degree of tensile strength and good softness, coupled with a required degree of liquid absorbency, and still has some biodegradation property. Therefore, the sheet can be flushed in a flush toilet without involving any appreciable increase in the volume of solid residues in a septic tank and/or in a sewage disposal plant and is therefore suitable for use in the form of a wet wiper in particular.

A seat belt tensioning device provided with a cylinder attached to the room of a vehicle, a piston slidably inserted into the cylinder, a rod of which one end is connected to the piston within the cylinder and of which the other end is connected to a seat belt outside of the cylinder through a joint member, and a piston operating means for moving the piston in one direction at an urgent time, is disclosed. The device is further provided with a piston operating energy absorbing member which is disposed between the joint member and the opposed end wall of the cylinder. When the piston moves to its limit stroke, the piston operating energy absorbing member is strongly sandwiched by the joint member and the end wall of the cylinder and is deformed by a predetermined load applied thereto to absorb the piston operating energy.
