が出来る。 In hot and humid countries like ours, so-called dehumidifying cooling is used as a means of cooling in the summer by absorbing moisture from indoor or outdoor air with a moisture absorbent to produce dry air, which is then cooled by an evaporative cooler and supplied indoors. is the most effective means of cooling, and if solar energy is used as a regenerating heat source for the moisture absorbent in such a dehumidifying cooling system, the operating cost of the system can be drastically reduced, and conventional absorption chillers can be used instead. The high cost of air conditioning systems that perform cooling operations can be eliminated.
そのため、本発明者はかかる要望に呼応すべく

That is, FIG. 1A shows the moisture absorption cycle of the dehumidifying and cooling system, in which moisture-containing air sucked in by the blower 1 from the air-conditioned area R such as a living room is passed through the air passages 2 and 3.
Dry air is generated through a moisture absorbing tank 5 filled with a moisture absorbing agent 4 such as silica gel, which is provided in the middle of the air, and is then transferred to an evaporative cooler 7 in which a moist porous body 6 containing moisture is housed. The temperature of the air is lowered by the evaporative cooling effect by passing through the air passage 6a in the porous body 6, and cold air is supplied from the air passage 8 to the air conditioning target area R.

熱によつて吸湿剤４を加熱再生している。 In the figure, reference numeral 9 denotes a cooling coil built into the moisture absorbent 4, through which the cooling water pumped up from the water storage tank 10 by the pump 11 passes, absorbing heat of adsorption during dehumidification operation, and preventing a decrease in dehumidification capacity; This is a moisture sprayer that sprays cooling water pumped up from the bottom of the evaporative cooler 7 by a pump 13 onto the wet porous object 6. In addition, FIG. 1B shows a regeneration cycle which is installed in parallel with the above-mentioned moisture absorption cycle and desorbs the moisture absorbent 4 whose moisture absorption capacity has decreased. The hot air is supplied to the dehumidifying layer 5, and the moisture absorbent 4 is heated and regenerated by convection heat transfer.

を有していた。 However, in such a conventional dehumidifying cooling system using solar heat, considerably high temperature air is required to desorb the moisture absorbent 4, so high temperature heat is collected in the solar collector 15 of the moisture absorbent regeneration circuit (FIG. 1B). As a result, the heat collection efficiency is low and the regeneration time is considerably long. Therefore, in order to compensate for the low heat collection efficiency, it is natural that the heat collection area of the heat collector 15 must be increased. The problem was that the size of the device made it difficult to install. In addition, in a system in which the moisture absorbent 4 is indirectly desorbed by the solar collector 15 through high-temperature air, there is a practical limit to the heat collection efficiency of the solar collector 15, so the efficiency of the entire system is low. However, when the amount of solar radiation is small, such as during cloudy days, there is a problem in that almost no solar energy can be used.

る。 The present invention has focused on the problems of the conventional solar dehumidification cooling system, and has been made with the aim of solving the above problems by directly heating the adsorbent with sunlight to increase the regeneration efficiency. ,
The feature is that a flat moisture absorbent with a wide light-receiving area is absorbed into the moisture absorption tank body whose top surface is covered with a transparent cover, and the temperature of the moisture absorbent is controlled by directly irradiating sunlight onto the plate-shaped moisture absorbent. Two solar direct sunlight regeneration type moisture absorption devices that regenerate the moisture absorbent with high efficiency and can easily switch between moisture absorption and regeneration operation by opening and closing the light shielding means provided in the gap between the transparent covers above the plate-shaped moisture absorbent body. When using the above methods and incorporating them alternately into the moisture absorption circuit and the regeneration circuit to continuously obtain dry air, the high temperature air generated between the transparent covers of the moisture absorption device during moisture absorption operation is transferred to the moisture absorption tank of the moisture absorption device during regeneration operation. It is an object of the present invention to provide a method for continuously generating dry air while increasing the temperature of desorption air by supplying it into a main body and increasing the regeneration efficiency of the device.

First, when dehumidifying and cooling is performed by the first moisture absorbing device A 1 , the air blower 45 is operated to introduce moisture-containing air in the air conditioning target area R into the hollow chamber 28 and allow it to pass through the plate-shaped moisture absorbing body 29 . The moisture is adsorbed by the internal moisture absorbent 44, and the generated dry air is sent out from the air outlet 26 and supplied to the evaporative cooler 7, where the temperature is lowered by the evaporative cooling action and the cold air is sent to the air conditioning target area R. to blow air.

までの間に急速に再生される。 On the other hand, when carrying out the regeneration operation of the second moisture absorption device A 2 in parallel with the moisture absorption operation of the first moisture absorption device A 1 , outside air is While introducing outside air from the inlet 38 using a blower (not shown), the high-temperature air in the accommodation space 33 is supplied to the hollow chamber 28 of the second moisture absorption device A 2 through the outlet 37 and the air passage 53;
The plate-shaped moisture absorbent body 29 housed in the hollow chamber 28 is regenerated. At this time, the hollow chamber 2 of the second moisture absorption device A2
Since the chamber above the plate-shaped moisture absorbent body 29 is tapered along the gas passage direction, the high-temperature air introduced into the plate-shaped moisture absorbent body 29 passes uniformly over the entire surface of the plate-shaped moisture absorbent body 29, and the moisture absorption agent 44 and heats the moisture absorbent 44, the plate-shaped moisture absorbent 29 is further heated by the sunlight directly irradiated on its surface, maintaining high regeneration efficiency, and at the same time heating the moisture absorbent 44. The moisture absorption device A1 is rapidly regenerated until the plate-shaped moisture absorption body 29 loses its moisture absorption ability.

的に行うことにより解消できる。 In addition, the switching between moisture absorption and regeneration operation of each moisture absorption device A 1 and A 2 is normally repeated several times a day, which is cumbersome to operate manually. While an appropriate drive mechanism is attached to the light-shielding blind operation mechanism, a temperature sensor is built into the moisture absorbing body 29, or a humidity sensor is provided at the air outlet 26, and the above-mentioned This problem can be solved by operating the drive mechanism or by controlling the drive mechanism in a timed manner using a timer to automatically perform switching.
