Synergistic and energy-saving system of precise machine room air conditioner

Abstract

The invention relates to an auxiliary device of a machine room air conditioner, in particular to a synergistic and energy-saving system of a precise machine room air conditioner. A spraying device isarranged below an outdoor unit of the air conditioner, wherein the spraying device comprises a main spraying pipe, and at least one branch spraying pipe is arranged on the main spraying pipe; the branch spraying pipes are arranged below the outdoor unit, and the end parts of the branch spraying pipes are provided with atomization spray heads; an electromagnetic control valve is arranged on the main spraying pipe, and a temperature control circuit is arranged on the electromagnetic control valve. The invention has simple structure, and the refrigerating effect of the air conditioner is effectively improved by carrying out spraying and water cooling on the outdoor unit of the air conditioner. In addition, the invention effectively improves the radiating capacity of the outdoor unit set, improves the working efficiency, shortens the working time of a compressor and correspondingly prolongs the service life of the machine room air conditioner.

Description

technical field [0001] The invention relates to an auxiliary device for an air conditioner in a computer room, in particular to an efficiency-enhancing and energy-saving system for a precision air conditioner in a computer room. Background technique [0002] In recent years, with the rapid increase in the installed capacity of computer equipment in data center computer rooms, some places, especially some data center computer rooms that were built earlier, are facing a serious shortage of cooling margins for the precision air conditioners originally configured in the computer room to varying degrees. Computer rooms more than ten years ago were basically low-density computer rooms, and the equipment was scattered on the ground or on the table. The heat generated per unit area in the computer room was very small. Neither the industry norm nor the size and power density of today's computer rooms adequately estimate what they should. The national computer room station site desig...

Problems solved by technology

The national computer room station site design specification and the "Computer Room Decoration Specification" issued by the banking system in 2000 all set the cooling capacity configuration of 200W-250W / square meter as the standard for the construction of the data center computer room. It is common for the load capacity of a single cabinet to exceed 5KW. For example, the precision air conditioner in the central computer room was designed according to the cooling capacity of 425W / square meter when it was first installed in 2005. At that time, the precision air conditioner in the computer room The total installed cooling capacity is 240KW, and the total load power of the computer equipment in the computer room is 90KW. Therefore, the six STULZ 381 modules have a large margin to undertake the cooling task. However, at the end of 2008, three and a half years later, the load in the computer room It has soared to more than 180 KW, and it is still showing a trend of continuous increase. In the hot season, the temperature of the precision air conditioner in the computer room has been set to 19 degrees, and the temperature at the other end of the cabinet is still around 25 degrees. The computer room is a national first-class load computer room that runs 7×24 hours without interruption. To increase air conditioning, it is necessary to weld a large number of air-conditioning copper pipes in the computer room, which will inevitably pose a threat to the running computer room.
