Embodiment approach ）

[0050] figure 2 It is a schematic diagram explaining the control method of the adsorption-type heat pump of embodiment. In addition, this embodiment also refers to figure 1 to explain.

[0051] Such as figure 1 As shown, the adsorption heat pump 10 has an evaporator 11, a condenser 12, and adsorbers 13a, 13b. A cooling water coil 11 a is arranged in the evaporator 11 , and a cooling water coil 12 a is arranged in the condenser 12 . Moreover, the heat transfer pipe 14 and the adsorbent 15 are respectively arrange|positioned in the adsorber 13a, 13b.

[0052] Such as figure 2 As shown, the cooling water coil 11 a of the evaporator 11 of the adsorption heat pump 10 is connected to the evaporator cooling water flow path 21 . A cooling water storage tank 31 for storing cooling water and a pump 32 for circulating cooling water between the cooling water storage tank 31 and the evaporator 11 are provided on the evaporator cooling water passage 21 . The cooling water stored in...

[0103] Next, results obtained by experimentally confirming the effect of the method for controlling the adsorption heat pump according to the embodiment will be described.

[0104] Figure 9 It is a schematic diagram explaining the apparatus used in the experiment. in the Figure 9 in, right with figure 2 Identical components are marked with the same reference numerals. A refrigeration unit 51 is arranged on the evaporator cooling water flow path 21 to replace figure 2 The cooling water storage tank and the pump 32 are illustrated. Assuming that the set temperature TL of the refrigeration unit 51 is 18°C, the set temperature T of the refrigeration units 33 and 35 M is 25°C.

[0105] In addition, in the experiment, one server 53 (RX300S6 manufactured by Fujitsu Corporation) and two analog servers 54 were used as electronic devices. Two CPUs 55 are installed on the server 53 , and cooling plates are respectively installed on the two CPUs 55 , and heat medium is discharg...

Abstract

To provide a method for controlling an adsorption heat pump, an information processing system, and a control device capable of efficiently operating the adsorption heat pump even if the temperature of a heat source for supplying heat used to regenerate an adsorption agent changes greatly. A method for controlling an adsorption heat pump is provided with: flow rate adjustment sections (43a-43c) capable of individually adjusting the flow rates of streams of a heat medium supplied to electronic devices (41a-41c); the temperature sensors (45a-45c) for individually detecting the temperatures of the streams of the heat medium discharged from the electronic devices (41a-41c); and a control unit (30). The control unit (30) controls the flow rate adjustment sections (43a-43c) on the basis of the outputs from the temperature sensors (45a-45c) so that the temperatures of the streams of the heat medium discharged from the electronic devices (41a-41c) are the same.

Description

technical field [0001] The invention relates to a control method, an information processing system and a control device of an adsorption heat pump (Heat Pump). Background technique [0002] In recent years, with the advent of a highly informationized society, people use computers to process a large amount of data, and in facilities such as data centers, multiple computers are often installed in the same room for unified management. For example, a plurality of racks (server racks) are installed in a computer room of a data center, and a plurality of computers (servers) are accommodated in each rack. Also, jobs are organically assigned to the computers according to the operating states of those computers, thereby efficiently processing a large amount of jobs. [0003] As the computer operates, a large amount of heat is generated from within the computer. As the temperature inside the computer rises, malfunctions and malfunctions may occur, so cooling the computer is particul...
