Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an adsorption refrigerator that uses the heat of vaporization Z of a refrigerant liquid to lower the temperature inside the refrigerator.

(b) Prior Art Figure 4 shows the basic structure 7 of a conventional sealed type suction gas, 1'-type suction pump.

An evaporation container (2) Z is housed inside the refrigerator car (1), and a steam pipe (3) is connected to the seafood container (2).
) is formed so as to extend upwardly,
A heat dissipation fin (4) is attached to the middle part of the steam pipe (3) to form a condenser part (5), and an adsorbent (6) for visually observing or releasing the refrigerant liquid (6) at the tip of the steam pipe (3). 7) This type of adsorption chiller connected to a heat collector (8) is equipped with an adsorbent (7) in the heat collector (8) due to solar heat during the day.
The refrigerant liquid (6) adsorbed on the refrigerant is vaporized and released from the adsorbent (7) as refrigerant vapor, and the adsorbent (7) is gradually depleted. - The refrigerant vapor is condensed and liquefied on the way down through the condenser section (5), becomes refrigerant liquid (6), and is stored in the evaporation container (2).At night, it is adsorbed on the contrary. As the temperature of the refrigerant (7) decreases, vapor in the steam pipe (3) begins to be absorbed.For this reason, the evaporation of the refrigerant liquid (6) in the evaporation container (2) is accelerated, and the heat of vaporization A cooling effect occurs.oo In this way, the conventional adsorption type/@freezer exerts a cooling effect Z only at night (2), and has no cooling effect in the dark when the outside temperature continues to rise during the day.Therefore, the temperature inside the refrigerator (1) - It is difficult to keep it at a low temperature during the day. Also, the absorbent (7) heats up only once in the daytime during the diurnal cycle, so there is a large heat loss and sensible heat loss. The drawback was that it could not be used effectively.

l/→ Invention 9 Purpose Invention 1. This is a V-, S-type refrigerator which has been developed in view of the problems of the conventional adsorption refrigerator as described above, and which can maintain a cooling effect day and night. The purpose of this project is to expand the scope of application of the reisuke.

Next, the operation of the present invention will be explained in detail with reference to Figures 1 and 2.

The rotation axis of the drum 00 is set r times east and west (line E = w direction).
Install the drum (') so that it matches C.
In) (7 heat building located above D B B (18b)
lt Receives sunlight during the day. Drum (10)
The cold liquid inside (11) is mostly at the level of ordinary liquid.

Heater A (18a) is exposed from the shadow of drum Cl0), is at a position where it begins to receive solar irradiation, and absorbent (171
This is immediately after the playback of . At this time, q'' Kiryu before adsorption in heater A (18a) is slow and the amount of catalytic fluid F in steam pipe A (14a) is small compared to the internal pressure of steam pipe B, (14b). Steam pipe A (14a)
The internal pressure has not yet risen, and when the connecting pipe A (1'2e,) passes the slope ('p-z) of the drum (10),
The cold tJv:5Q'' flowing from inside the ram is connected to the connecting pipe A (1'l a) and the liquid fjqW A (15er
) and part of steam pipe A (14B)! Satisfied. The heat collector B (11) absorbs solar heat energy and absorbs the almost internal adsorbent (171 is completely Kiryu. Therefore, the internal pressure due to the refrigerant vapor in the steam pipe B (14'tl) increases to 7 (H The liquid reservoir pipe B ('151))
7jl FIn is lower than the liquid level in the drum (10). That is, from heat collector A (188,) to heat collector B (18,
In the process of moving to the position b), some of the finishing fluid FI IJ in the liquid reservoir pipe A (13a) flows into the drum (t).
[ru. Of course, the refrigerant vapor generated during the regeneration process of the Sakaru agent from the +-heater A (1'8a) to the collector B ('1'8'tl)-1 is condensed in the condenser section A (16a). The liquid is liquefied and collected in the liquid storage pipe p (15e, ).

fIl tube A (15al, B (13'l)),
Refrigerant liquid present in 0 (13C)! This is a gravitational imbalance caused by 111f2.

That is, when the state of Figure 2 is jp,l=,l2, the liquid reservoir pipe A (
The refrigerant liquid inlet in 13a) gives a counterclockwise rotational moment of 7 to the drum float, and the liquid reservoir pipe B (1151))
On the other hand, the refrigerant liquid Qll inside gives a clockwise rotational moment of 7, but the refrigerant liquid: The storm of the refrigerant liquid is superior to the liquid storage pipe A (1 3a), and in the end, the drum IQ) moves in the direction of the arrow (Xl). Then, the sun's irradiation continues until <1
The balance rotors A, B, and O continuously change their respective relative positions, and the evaporation of the refrigerant liquid 111 in the drum ([0]) produced during this process produces a cooling effect of 7. ) Surrounding air can be cooled.

During the rotation of the drum (00), it is necessary to keep the pressure inside the drum (10) low in order to ensure smooth movement of the refrigerant liquid (0υ), but this is due to the position of the heat collector B (181)). Heat collector B of balance rotor B has reached the position of heat collector 'a (i sc ). (18b) is gradually cooled and the adsorbent 117) begins to absorb refrigerant vapor,
It is possible to keep the pressure in the drum 00) as low as 2. At the same time, the drum (10) emits a cooling effect by surface evaporation of the refrigerant liquid inlet.

At night, as with conventional adsorption refrigerators, the adsorbents in all the heat collectors adsorb refrigerant vapor and accelerate the evaporation of the refrigerant liquid, so the heat of vaporization cools the air around the drum. It is possible.

(F) Effects of the Invention As described above, the present invention comprises an internal f: a rotatable drum filled with a refrigerant liquid, a plurality of communication pipes arranged radially from the drum, and an outer periphery of the drum. ? A plurality of steam pipes 1 and 1 are arranged at one end of each steam pipe. &Equipped with a heat collector with a built-in adhesive, and a liquid storage pipe that connects each of the communication pipes and each of the trachea Z to each other./Since it is freezing M, even during the daytime, the refrigerant liquid M collected in each liquid storage pipe is ! : : Due to the stick imbalance, the drum automatically rotates, and in the process, the internal pressure of the drum decreases, promoting the production of refrigerant liquid and creating a cooling effect due to the heat of vaporization. There is no need to worry about any inconvenience caused by the temperature rising.
Because high air is present and repopulated repeatedly, heat radiation loss and apparent loss are small, and solar thermal energy can be effectively utilized.
