Automatic control refrigeration system for high-density computer room and method thereof

Abstract

The invention provides an automatic control refrigeration system for a high-density computer room and a method thereof. By arranging an interlayer baffle plate and a thermal cavity baffle plate in the computer room, a thermal cavity, a channel of new wind and return wind, and a channel of cooling air flow are formed in the computer room; the thermal cavity is communicated with the outside throughan exhaust fan; the channel of the new wind and return wind is communicated with the outside through an electric wind valve with a filter; the thermal cavity, the channel of cooling air flow and the outside are respectively provided with a temperature sensor of the thermal cavity, a temperature and humidity sensor of the computer room, and a temperature and humidity sensor of the outside; the temperature sensor of the thermal cavity, the temperature and humidity sensor of the computer room, and the temperature and humidity sensor of the outside are respectively connected with an I/O port of amain controller; an air conditioner, the exhaust fan, the electric wind valve with the filter, an electric wind valve of a new wind port, an electric wind valve for isolation of inner and outer cycle, and super-cool resistant blower are respectively controlled by the main controller; and the actions of executing mechanisms such as air conditioners, exhaust fans, various wind valves and the like are automatically controlled according to the values of the temperature outside a detecting room and the temperature in the computer room so that the temperature in the computer room is kept to reach aspecified range.

Description

technical field [0001] The invention belongs to the field of air-conditioning and refrigeration, and in particular relates to a design scheme and method for utilizing an outdoor cold source and air-conditioning refrigeration, a corresponding air flow channel and an automatic control system of the whole system. Background technique [0002] In a high-density computer or communication room that operates continuously, the power consumption of the equipment is large, generally tens to hundreds of kilowatts or even thousands of kilowatts, and the heat source is concentrated and the heat density is high. At present, the cooling method of the equipment is the indoor air circulation of the air conditioner. The power consumed by the air conditioning equipment in this way is close to or even exceeds 50% of the power consumption of the equipment, and its energy consumption is considerable. At the same time, due to the different numbers of equipment nodes installed in the high-density ...
