FIG. 2 is a schematic view showing a heat recovery mode of a heat recovery apparatus of a suction heat pump according to an embodiment of the present invention. Fig.

1 (a), the heat recovery apparatus 100 of the adsorption type heat pump will be described with reference to FIG. 1 before describing the heat storage mode of the heat recovery apparatus 100 of the adsorption heat pump according to the embodiment of the present invention, The basic structure of which will be described.

1 (a), a heat recovery apparatus 100 of a suction heat pump according to an embodiment of the present invention includes a adsorption bed 110, a heat storage unit 120, and a circulation flow path 130 .

The adsorption bed 110 includes a moisture-absorbing material (not shown) capable of absorbing moisture. For example, the moisture absorbing material of the adsorption bed 110 may be made of silica gel or a porous polymeric dehumidifying material made of a polymer material. The polymer dehumidifying material has a hygroscopicity more than four times that of silica gel, and the weight of the adsorption bed 10 can be reduced to a level of one-fourth, and the antibacterial / antifungal property is improved. It is a suitable material.

Specifically, the adsorption bed 110 can adsorb the adsorbate at the adsorption temperature T _A and desorb the adsorbate at the regeneration temperature T _R. Here, water or methanol may be used as the adsorbent, but water may be most suitable considering price, toxicity, combustibility, latent heat of evaporation, affinity for moisture absorbing materials, and the like.

The heat storage unit 120 may include a heat storage medium having a temperature distribution of the regeneration temperature T _R from the adsorption temperature T _A. As the heat storage medium, it is preferable to use a substance having a large specific heat, and therefore, it is preferable to use water or a latent heat storage material.

As an example, the heat storage medium included in the heat storage part 120 may have a continuous temperature distribution between the adsorption temperature (T _A ) and the regeneration temperature (T _R ). That is, when the adsorption temperature (T _A ) is set at 30 degrees Celsius and the regeneration temperature (T _R ) at 90 degrees Celsius, it means that the heat storage medium can have any temperature between 30 degrees Celsius and 90 degrees Celsius . In particular, the thermal storage medium may have a linear temperature distribution from 30 degrees Celsius to 90 degrees Celsius, but embodiments of the present invention are not so limited and the thermal storage medium may have a non-linear temperature range between 30 degrees Celsius and 90 degrees Celsius Distribution.

As another example, the heat storage unit 120 may include a plurality of partitions (see PT _n and PT _n 'in FIG. 3) (n is 1 to 4), and a heat storage medium May be included. This will be described in detail with reference to FIG. However, for convenience of explanation, the heat recovery apparatus 100 of the adsorption heat pump according to the embodiment of the present invention shown in FIGS. 1 and 2 includes a heat storage unit 120 without a separate partition However, the embodiments of the present invention are not limited thereto. That is, the column storage unit 120 of FIGS. 1 and 2 may also be configured to include a plurality of partitions, such as the column storage unit 220 shown in FIG.

The circulation channel 130 connects the adsorption bed 110 and the heat storage unit 120 to provide a passage through which the heat transfer medium circulates between the adsorption bed 110 and the heat storage unit 120. That is, the heat transfer medium passing through the heat storage part 120 can be transferred to the adsorption bed 110 along the circulation flow path 130. The heat transfer medium passes through the adsorption bed 110, Lt; / RTI >

Meanwhile, the heat storage unit 120 and the circulation channel 130 may be coupled to each other to be movable relative to each other. 1 and 2, the circulation channel 130 may be coupled to the circulation channel 130 such that the heat storage part 120 can move relative to the circulation channel 130 in a state where the circulation channel 130 is fixed at a predetermined position. have. As another example, although not shown in the drawings, the circulation flow path 130 may be coupled to each other so that the circulation flow path 130 is movable in a state where the heat storage part 120 is fixed at a predetermined position. Hereinafter, for convenience of explanation, the heat storage unit 120 is coupled to the circulation channel 130 so as to be movable with the circulation channel 130 fixed.

Next, an operation example of the heat recovery apparatus 100 of the adsorption heat pump according to the embodiment of the present invention will be described with reference to FIG.

1 is a conceptual view schematically showing a heat storage mode of the heat recovery apparatus 100 of the adsorption heat pump. 1 (a), the circulation flow path 130 may be coupled to the first position P ₁ and the second position P ₂ of the heat storage unit 120. Here, the first position P ₁ and the second position P ₂ refer to a predetermined position where the heat storage medium included in the heat storage unit 120 is relatively high, ₁ is a position where the heat transfer medium flows from the adsorption bed 110 to the heat storage 120 and the second position P ₂ is a position where the heat transfer medium flows out from the heat storage 120 to the adsorption bed 110 side. Location.

Hereinafter, the case where the temperature difference between the heat transfer medium and the heat storage medium is very small for the sake of convenience will be described as a reference. In practice, since the heat transfer coefficient between the heat transfer medium and the heat storage medium is finite, the temperature of the heat transfer medium may be slightly higher than the temperature of the heat storage medium in the heat storage mode. In contrast, in the heat recovery mode, May be slightly lower than the temperature of the medium.

That is, the heat transfer medium flowing into the heat storage part 120 from the adsorption bed 110 may be introduced into the first position P ₁ . At this time, the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage part 120 may substantially correspond to the regeneration temperature T _R , which is the temperature of the adsorption bed 110. The first temperature T ₁ of the heat storage medium included in the first position P ₁ of the heat storage unit 120 may be lower than the regeneration temperature T _R. Therefore, the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage unit 120 transfers heat to the heat storage medium included in the heat storage unit 120, At a second position P ₂ . I.e. (T _1), the first temperature of the heat transfer medium of the first position (P ₁₎ may be formed above the second temperature (T ₂₎ of the heat transfer medium of the second position (P _2).

The heat transfer medium having the second temperature T ₂ at the second position P ₂ of the heat storage part 120 is heated again through the adsorption bed 110 and the adsorption bed 110 is heated by the adsorption bed 110, Lt; RTI ID = 0.0 > 110 < / RTI >

As described above, when the heat transfer medium that is transferred from the adsorption bed 110 to the adsorption bed 110 through the heat storage unit 120 flows into the heat storage unit 120 again from the adsorption bed 110 1 (b), the heat transfer medium moves to the first position P ₁ (a) shown in FIG. 1 (a) as the heat storage portion 120 moves upward by a predetermined distance with respect to the circulation flow passage 130, And the third position P ₃ of the heat storage unit 120 that is different from the first position P ₃ .

At this time, the third temperature T ₃ of the heat transfer medium flowing into the third position P ₃ is greater than the third temperature T ₃ of the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage part 120 in the previous step May be formed to be lower than the first temperature (T ₁ ) of the medium. That is, the first temperature T ₁ of the heat transfer medium may be higher than the third temperature T ₃ of the heat transfer medium at the third position P ₃ .

The heat transfer medium flowing into the third position P ₃ of the heat storage part 120 from the adsorption bed 110 is heated in the same manner as the heat storage part 120 It can transfer heat to the storage medium, and can be discharged at the fourth position (P ₄ ) at a lowered temperature. I.e., (T _3), the third temperature of the heat transfer medium of the third position (P ₃₎ may be formed above the fourth temperature (T ₄₎ of the heat transfer medium in a fourth position (P _4).

By the flow of the heat transfer medium in the heat storage mode as described above, the sixth temperature T ₆ of the heat transfer medium at the sixth position P ₆ of the heat storage part 120 shown in FIG. 1 (c) adsorption beds (110), as reaching the temperature (T _a) is repeated until the adsorption temperature (T _a), heat the thermal energy corresponding to a difference between the regeneration temperature (T _R) and the adsorption temperature (T _a) And may be stored in the storage unit 120.

Next, another operation example of the heat recovery apparatus 100 of the adsorption heat pump according to the embodiment of the present invention will be described with reference to FIG.

2 is a conceptual diagram schematically showing the heat recovery mode of the heat recovery apparatus 100 of the adsorption heat pump. As can be seen from the figure, the flow direction of the heat transfer medium in the heat recovery mode shown in FIG. 2 is opposite to the case of the heat storage mode shown in FIG.

2 (a), the circulating flow path 130 may be coupled to the first position P ₁ and the second position P ₂ of the heat storage unit 120. Here, the first position P ₁ and the second position P ₂ refer to positions different from the first position and the second position in FIG. That is, the first position P ₁ and the second position P ₂ shown in FIG. 2 (a) indicate a predetermined position where the heat storage medium included in the heat storage unit 120 is relatively low, The first position P ₁ is a position where the heat transfer medium flows from the adsorption bed 110 to the heat storage portion 120 side and the second position P ₂ is a position where heat transfer is performed from the heat storage portion 120 to the adsorption bed 110 side. It is the location where the media leaks.

That is, the heat transfer medium flowing into the heat storage part 120 from the adsorption bed 110 may be introduced into the first position P ₁ . At this time, the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage part 120 may substantially correspond to the adsorption temperature T _A , which is the temperature of the adsorption bed 110. The first temperature T ₁ of the heat storage medium included in the first position P ₁ of the heat storage unit 120 may be higher than the adsorption temperature T _A.

Accordingly, the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage part 120 recovers heat from the heat storage medium included in the heat storage part 120, At a second position P ₂ . I.e. (T _1), the first temperature of the heat transfer medium of the first position (P ₁₎ can be formed lower than the second temperature (T ₂₎ of the heat transfer medium of the second position (P _2).

The heat transfer medium having the second temperature T ₂ at the second position P ₂ of the heat storage part 120 passes through the adsorption bed 110 again and is cooled. Can be heated more than before because heat is recovered from the heat transfer medium passing through the adsorption bed (110).

As described above, when the heat transfer medium that is transferred from the adsorption bed 110 to the adsorption bed 110 through the heat storage unit 120 flows into the heat storage unit 120 again from the adsorption bed 110 The heat transfer medium is moved to the first position P ₁ shown in FIG. 2 (a) as the heat storage portion 120 moves downward a predetermined distance with respect to the circulation flow passage 130 as shown in FIG. 2 (b) And the third position P ₃ of the heat storage unit 120 that is different from the first position P ₃ .

At this time, the third temperature T ₃ of the heat transfer medium flowing into the third position P ₃ is greater than the third temperature T ₃ of the heat transfer medium flowing from the adsorption bed 110 to the first position P ₁ of the heat storage part 120 in the previous step May be formed higher than the first temperature (T ₁ ) of the medium. That is, the first temperature T ₁ of the heat transfer medium may be lower than the third temperature T ₃ of the heat transfer medium at the third position P ₃ .

2 (a), the heat transfer medium flowing from the adsorption bed 110 to the third position P _{3 of the} heat storage part 120 is heated in the same manner as the heat storage part 120 Heat can be recovered from the storage medium, and can be discharged at the fourth position (P ₄ ) at a higher temperature. That is, the third temperature (T3) of the heat transfer medium of the third position (P ₃₎ may be formed below the fourth temperature (T ₄₎ of the heat transfer medium in a fourth position (P _4).

The sixth temperature T ₆ of the heat transfer medium at the sixth position P ₆ of the heat storing portion 120 shown in Fig. 2 (c) is regenerated by the flow of the heat transfer medium in the heat recovery mode as described above, It is repeated until the adsorption bed 110 is reproducing temperature (T _R), as reached (T _R), to recover the heat energy corresponding to the difference between the regeneration temperature (T _R) and the adsorption temperature (T _a) The adsorption bed 110 can be regenerated.

The first position P ₁ to the sixth position P ₆ shown in FIGS. 1 and 2 are adopted for convenience of explanation, and the actual heat recovery apparatus 100 of the adsorption heat pump is arranged at the first position P _{As the} heat storage part 120 and the circulation flow path 130 are coupled at a plurality of successive positions T _n (n is a natural number of 1 or more) between the _first position 6 and the sixth position P ₆ , (Heat recovery mode) in which the temperature of the adsorbent 110 is cooled from the regeneration temperature T _R to the adsorption temperature T _A (heat storage mode), and the adsorption temperature T _A is increased to the regeneration temperature T _R Can be repeated.

That is, a heat storage medium having any temperature between the adsorption temperature (T _A ) and the regeneration temperature (T _R ) may be included in each partition (PT _n ) (PT _n ' . This feature can also be applied when the partition (PT _n ) (PT _n ') is 10 or more. Hereinafter, for convenience of explanation, the column storage unit 220 includes eight partitions (PT _n ) (PT _n ') (n is 1 to 4), and when n is different, each partition (PT _n ) (PT _n ') (where n is 1 to 4), a thermal storage medium having a different temperature is included.
