摘要： PROBLEM TO BE SOLVED: To provide a natural evaporation humidifier that can be reduced in material cost and, in addition, in manufacturing cost by reducing the assembling man-hour of the humidifier.
SOLUTION: A water supply route 64 housing a water supply pipe 56 is formed of a long cover 60 having an opening on one side of its cross section and a long water absorbing member 62 covering the opening in the cross section of the cover 60. Many plate-shaped evaporating members 70 and many corrugated evaporating members 72 are alternately and adjacently arranged below an evaporating member assembly 68 provided with auxiliary water absorbing members 78 on one of the corrugated evaporating member 72 so that the upper surface of the uppermost auxiliary water absorbing member 78 may come into contact with the lower surface of the water absorbing member 62. Consequently, the water discharged from the water supply pipe 56 can be infiltrated into the evaporating members 70 and 72 from the water absorbing member 62 through the auxiliary water absorbing members 78.

摘要： PROBLEM TO BE SOLVED: To provide a humidifying element which is prevented from the occurrence of swelling even after a feed of water, does not need a reinforcing material, has an excellent productivity, hardly undergoes bursting of an element due to clogging and freezing, and has also an excellent long period stability. SOLUTION: Steam permeable and water impermeable moisture permeable films are formed on both surfaces of a water holding layer for humidification capable of absorbing and holding water for humidification. The humidifying element is formed of a humidifying sheet approximately in a rectangular shape and provided on the first short side S1 side with a through-hole H for a feed and a through-hole H' for discharge and has a partition part 8 situated at a water holding layer for humidification to form a flow passage through which water for humidification flows to the through-hole H' for discharge after it flows along a first long side L1, a second short side S2, and a second long side L2. A flow passage width (Pb) consisting of a second short side S2 and a partition part 6 is narrower than a flow passage width (Pa) consisting of the first long side L1 and the partition part 6 and wider than a flow passage width (Pc) consisting of the second long side L2 and the partition part 6.

摘要： PROBLEM TO BE SOLVED: To implement a distilling plant which achieves high distilling efficiency in a desert zone. SOLUTION: The distilling plant 25 is constituted of a condenser 2, an evaporator 3, a blower 5, and a drain pan 7, and it is set in a storage house 30. Outside air enters the storage house 30 from an air intake port 36, and flows from an air suction port 6 into the distilling plant 25 to be cooled in the evaporator 3. Thus, moisture in air is condensed, deposited on the evaporator 3, and then dropped on the drain pan 7. Therefore, by collecting the dropped moisture, water can be obtained. The condenser 2 is set on a downstream side of the evaporator along the flow of outside air. As a result, the condenser 2 is cooled by air cooled by the evaporator 3, and therefore refrigerant gas in the condenser 2 can be sufficiently cooled, to thereby enhance the distilling efficiency in the evaporator 3.

摘要： PROBLEM TO BE SOLVED: To provide a drop type vaporizing humidifier which prevents water from springing out from an air outlet of an air discharge passage or the like of an air conditioner even in the case when a water repellent substance is included in a humidified water supply or in the case when the humidified water supply quantity is increased resultant from the operational failure of a water supply control device of the humidifier. SOLUTION: A pipe insertion hole is provided in a humidification element main body 12 having a water holding property and a water suction property and a ventilating property where a water supply pipeline 14, which supplies humidification water, is provided in the pipe insertion hole. This humidifier comprises a cylinder-shaped diffusion element 40, which comprises a raw material which adsorbs a substance having water holding, water suction and water repellent properties inside the pipe insertion hole of the humidification element main body 12 and outside the water supply pipeline 14. A drain water passage, which communicates with the inside of the cylinder-shaped diffusion element 40, is provided inside the humidification element main body 12 where the humidification supply water, which overflows at the cylinder-shaped diffusion element, is introduced to a drain pan 18 by way of the drain water air.

摘要： PURPOSE:To prolong the switching life of a valve, by stopping a compressor for a predetermined period of time through a timer or the like immediately before switching a four-way valve, bringing the pressure on the discharging side and the pressure on the suction side close to each other to thereby reduce a pressure difference between the two sides, and then switching the four-way valve. CONSTITUTION:A dehumidifier comprises a refrigeration cycle, a blower, an electric apparatus, and a cabinet and stays for assembling them, the refrigeration cycle comprising an evaporator, a reheater, a condenser and a few kinds of heat exchangers and being capable of a cooling operation and a reheating and dehumidifying operation by controlling these components by a four-way valve and a solenoid valve. In the dehumidifier, when a signal for switching from the cooling operation to the reheating and dehumidifying operation or vice versa is outputted, a timer is operated, and a compressor is stopped. As a result, the pressures on the high-pressure side and the low-pressure side of the refrigeration cycle are brought closer to the saturation pressure of the atmosphere at that moment, so that the pressure difference across the four-way valve is reduced. Then, with the time set on the timer is up, a switching signal for the four-way valve is outputted, only after which the valve is switched. The pressure difference across the four-way valve is small at the time of switching the valve, so that the switching life of the valve can be prolonged.
