Machine room air-conditioning energy-saving operation control system

Abstract

The invention provides a machine room air-conditioning energy-saving operation control system, mainly comprising a control host (1), a temperature compensation box (2) and a temperature sensor (3). The system is characterized in that the temperature compensation box (2) and the temperature sensor (3) are connected with the control host (1) through a data wire to form a complete control system, wherein the control host (1) comprises a temperature set module (11), a temperature detection module (12), a difference comparison module (13), a different determination module (14) and a compensation output module (15); the temperature sensor (3) is arranged on equipment required to be refrigerated; a target object is strictly taken as direction to realize accurate temperature control; the temperature compensation box (2) is made of refrigerating semi-conductor, and is connected with a return air temperature probe on an air return port (41) of an air conditioner (4); and the control host (1) controls the temperature compensation box (2) to perform temperature correction and compensation on return air temperature of the air conditioner (4) at proper time, and controls and adjusts the start and stop operation of a compressor of the air conditioner (4) so as to achieve the designing aim.

Description

technical field [0001] The invention relates to an operation control system of an air conditioner in a computer room, in particular to an environment-friendly and energy-saving energy-saving operation control system for an air conditioner in a computer room to achieve precise temperature control in the computer room. Background technique [0002] The structural characteristics of the ordinary split air conditioner in the existing computer room make it unreasonable in operation and inadequate in management in the specific environment of the computer room. Due to human factors, it is impossible to accurately grasp the actual temperature distribution and reasonable settings, especially for work The temperature setting is often estimated and roughly guessed based on experience, especially the unavoidable low temperature setting, which causes an astonishing waste of energy: 1.

[0002] The structural characteristics of the ordinary split air conditioner in the existing computer room make it unreasonable in operation and inadequate in management in the specific environment of the computer room. Due to human factors, it is impossible to accurately grasp the actual temperature distribution and reasonable settings, especially for work The temperature setting is often estimated and roughly guessed based on experience, especially the unavoidable low temperature setting, which causes an astonishing waste of energy: 1. Ordinary split air conditioners use the temperature of the return air outlet to detect and control the start and stop of the air conditioner compressor. To achieve the purpose of cooling, however, because the layout of the cabinet equipment in the computer room is completely different from the distribution of ordinary household and commercial indoor objects that mainly live around the wall, they are all located in the center of the room, resulting in poor air circulation and temperature distribution. Unevenness, the temperature of the return air outlet of the air conditioner cannot truly reflect the ambient temperature and the temperature of the refrigerated equipment, and the uneven distribution of indoor temperature leads to inaccurate and inaccurate temperature setting values. Calculated according to the maximum cooling load, it needs to meet the cold and heat exchange in extreme weather (severe summer), the cooling capacity is generally too large, leaving a certain margin, the compressor is usually intermittent operation, but, due to the time delay of the air conditioner Instructions lead to unnecessary extension of cooling time and waste of electric energy. Third, due to the artificial low temperature setting, the air conditioner is in an unnecessary cooling operation state for a long time, resulting in artificial waste. In summary, the above reasons lead to The excessive cooling of the air conditioner in the computer room has produced a lot of energy waste. In order to meet the demand for energy use, it is urgent to use the temperature detection of the cooling object instead of the return air temperature detection of natural circulation to control the operation of the air conditioner compressor. Temperature compensation technology to curb the unnecessary work of the compressor caused by the artificial low temperature setting, so as to achieve an energy-saving operation control system to meet the cooling needs of people's computer room equipment
