Problems solved by technology

[0005] The above two operating modes need to judge the indoor and outdoor temperature at any time, and switch by adjusting the operating status of each device according to the user's setting. At present, the existing air conditioner controller has a weak ability to detect the outdoor temperature, and the number of devices that can be controlled is small. , there are not enough user-settable parameters to precisely control its normal operation

Abstract

The invention relates to a controller for a refrigerant circulation blending machine room special machine, which comprises a singlechip module cured with control program, and a button module, a temperature detection module, a relay output module, a power supply module, a display module, a network communication interface module and a protection module that are matched with the singlechip module. The controller ensures the refrigerant circulation blending machine room special machine to run in an accurate working mode according to the indoor and outdoor temperature and the set temperature, gives full play to the unique energy-saving advantage of the refrigerant circulation blending machine room special machine on the premise of guaranteeing the normal temperature range of a machine room, and leads the effects of energy conservation and emission reduction to be maximized.

Description

technical field [0001] The invention relates to a controller for a special machine room with refrigerant circulation combined use, which belongs to an electrical operation control device, and is especially suitable for a special machine room with refrigerant circulation combined use, and controls the combined use of refrigerant circulation by detecting and judging the indoor and outdoor temperatures. The operation mode of the special machine in the computer room can achieve energy-saving effect. Background technique [0002] With the widespread application of large computers and the popularization of mobile communications, special machine equipment in computer rooms has been widely used. Since the special machine in the computer room is a direct evaporative air-conditioning system that operates throughout the year, it is still necessary to cool down the computer room even in the cold winter (when the external temperature is very low), resulting in extremely high operating co...
