Abstract

The invention discloses a method and device for controlling a refrigerating device, and a refrigerating system, wherein the method comprises the steps of: detecting a first wind pressure and a second wind pressure, wherein the first wind pressure is a wind pressure of a gas exhausted by the refrigerating device, the second wind pressure is a wind pressure of gas exhausted by a refrigerated device, the refrigerating device and the refrigerated device are positioned in a closed space, the refrigerating device is used for sucking the gas exhausted by the refrigerated device and conveying the refrigerated gas to the refrigerated device; and controlling the rotating speed of an air blower of exhausting the gas of the refrigerating device according to the detected difference of the first wind pressure and the second wind pressure. Through detecting and comparing the wind pressure of the gas exhausted by the refrigerating device and the wind pressure of the gas exhausted by the refrigerated device, and controlling the rotating speed of the air blower of the refrigerating device according to a comparison result, the rotating speed of the air blower of the refrigerating device is regulated and the actual refrigerating effect of the refrigerated device is not influenced. The stability of the wind pressure in the closed space can be ensured and the problem of resource waste is avoided.

Description

technical field [0001] The invention relates to a control method and device for refrigeration equipment and a refrigeration system. Background technique [0002] Server cabinets are usually densely packed with multiple servers, switches, storage devices and other equipment, which consume power and generate heat. With the emergence of high-performance servers, their power consumption is also increasing. If the heat generated by these heat loads is not dissipated in time, it will be extremely detrimental to the performance, safety and service life of the equipment. The demand for cooling capacity and air volume required by the high-density configuration of servers poses unprecedented challenges to refrigeration equipment. [0003] At present, the main cooling method is the air conditioner with horizontal air supply in the closed passage. The air supply method adopts the horizontal method, and the air supply volume adopts the "air supply on demand" method, which is essentially...
