[0037] figure 2 It is a schematic diagram which shows the adsorption-type heat pump system which concerns on 1st Embodiment.

[0038] The adsorption heat pump 20 includes an evaporator 21 , a condenser 22 arranged above the evaporator 21 , adsorbers 23 a and 23 b arranged in parallel between the evaporator 21 and the condenser 22 , and a control unit 30 . The space inside the adsorption heat pump 20 is decompressed to about 1 / 100 to 1 / 10 of the atmospheric pressure, for example.

[0039] In addition, in this embodiment, two adsorbers 23a, 23b are arranged in parallel between the evaporator 21 and the condenser 22, but three or more adsorbers may also be arranged between the evaporator 21 and the condenser 22. device.

[0040] The adsorption-type heat pump system according to this embodiment includes the above-mentioned adsorption-type heat pump 20 , the air cooling device 29 , and the cooling water circulation pump 31 . The adsorption heat pump 20 is arranged, for example,...

Deformed example 1

[0075] In the first embodiment described above, in the air cooling device 29 , the cooling water is cooled by blowing outside air from the blower fan 29 c to the fins 29 a. However, for example if image 3 As shown in (a), you may provide the spray piping 51a, and spray water to the fin 29a. In this case, since the latent heat is taken from the fins 29a when the water is vaporized, the cooling capability of the air cooling device 29 is improved compared to the case where only the outside air is blown to the fins 29a.

[0076] and, if image 3 As shown in (b), water may be sprayed from the injection pipe 51b arranged between the blower fan and the fin 29a, and the air whose temperature has been lowered by the heat of vaporization may be blown toward the fin 29a. In this case, with image 3 The case of (a) is the same, and the cooling capability of the air cooling device 29 improves compared with the case where only the external air is blown to the fin 29a.

Deformed example 2

[0078]In the first embodiment described above, the presence or absence of dew condensation in the adsorber is determined based on the difference between the pressure in the condenser 22 and the pressure in the adsorber (adsorber 23a or adsorber 23b ) during the regeneration step. However, for example if Figure 4 As an example, humidity sensors 52a, 52b may be arranged in the adsorbers 23a, 23b, and the control unit 30 may determine the presence or absence of dew condensation based on the outputs of these humidity sensors 52a, 52b.

[0079] and, for example Figure 5 As an example, condensation sensors 53a, 53b whose conductivity changes due to condensation may be disposed in the adsorbers 23a, 23b, and the control unit 30 may determine the presence or absence of condensation based on the output of the condensation sensors 53a, 53b.

Abstract

The present invention provides an adsorption heat pump system and a driving method of the adsorption heat pump that can be used even in relatively small-scale facilities. The adsorption heat pump system has: an adsorption heat pump (20) equipped with a condenser (22) for condensing refrigerant vapor; The coolant is air-cooled and supplied again to the condenser (22); and the control unit (30). The controller (30) controls the flow rate of the coolant supplied to the condenser (22) based on the temperature difference between the coolant supplied to the condenser (22) and the coolant discharged from the condenser (22).

Description

technical field [0001] The invention relates to an adsorption heat pump system and a driving method of the adsorption heat pump. Background technique [0002] In recent years, with the advent of a highly informationized society, computers are used to process a large amount of data. In facilities such as data centers, multiple computers are often installed in the same room for unified management. For example, in a data center, a plurality of racks (server racks) are installed in a computer room, and a plurality of computers (servers) are accommodated in each rack. Furthermore, tasks are organically allocated to each computer according to the operating states of these computers, and a large number of tasks are processed efficiently. [0003] As the computer operates, a large amount of heat is generated from the computer. If the temperature inside the computer rises, it will cause malfunctions and failures, so it is important to cool the computer. Therefore, generally in a d...
