Air conditioning system and air conditioning control method for server room management

Abstract

A system for a server room management includes an air-conditioning control device including: an acquisition unit; a setting unit that sets content for generating supply air at temperature, absolute humidity, and relative humidity within target range, based on outside air temperature and humidity as well as return air temperature; and a controller controlling amount of outside air, amount of return air, control amount of humidifier, control amount of cooler, and amount of air blown by blower, based on the content. If the outside air is within range greater than absolute humidity upper limit, or within range greater than enthalpy upper limit and greater than the temperature upper limit, the setting unit compares outside air and return air, and then determines, in accordance with the comparison, whether to set the content so that the cooler performs cooling by minimizing or maximizing the amount of the outside air.

Description

technical field [0001] Embodiments of the present invention relate to an air conditioning system and an air conditioning control method for server room management. Background technique [0002] In recent years, with the advancement of IT in various fields, the need for a data center to provide customers with connection lines to the Internet and maintenance and operation services has increased. [0003] In the server room of the data center, a large number of servers are usually installed, so the heat generated is relatively high. In such a server room, in order for these servers to operate normally, it is necessary to properly air-condition the server room so as to maintain an environmental condition within a predetermined range. [0004] As a technique for cooling a room in which a large number of computers are installed, such as a server room in a data center, there is an air-conditioning system configured to blow air sucked in from the lower space of the room to the uppe...

Problems solved by technology

[0011] However, when the load that should be air-conditioned such as the server room of the data center is information equipment, it has the following characteristics that are different from the state in a general building. The load is almost all sensible heat loads, and the set temperature and humidity only Just within a certain range, no CO is generated in the load 2 , not required for protection against CO 2 Concentration increases, etc., but conventionally, air-conditioning control corresponding to these characteristics has not been performed, and there is a problem that unnecessary energy is sometimes consumed
