Embedded cabinet air-conditioning refrigeration system

Abstract

The invention discloses an embedded cabinet air-conditioning refrigeration system composed of an indirect refrigeration terminal and a direct refrigeration terminal connected via a heat-exchange cabinet. The indirect refrigeration terminal comprises a cold water unit, a liquid storage cylinder and an indirect refrigeration terminal water pump connected in sequence, wherein the direct refrigeration terminal comprises a direct refrigeration terminal water pump and an embedded air-conditioning cabinet connected together; both the indirect refrigeration terminal water pump and the direct refrigeration water pump are communicated with the heat exchange cabinet; and a heat exchanger, a temperature sensor and a flow controller are arranged in the heat exchange cabinet. The embedded cabinet air-conditioning refrigeration system can effectively radiate the heat caused by that electric components consume power energy, provide an ideal temperature and humidity environment for the interiors of various cabinets, insulate dust and active gases in the external environment, prolong the service life of electric elements, and improve the reliability of a machine system, is particularly suitable for high-heating cabinets, communication, communication devices, data processing boxes and the like, has excellent practicability, and can bring good economic effectiveness and social effect.

Description

technical field [0001] The invention relates to an air-conditioning unit, in particular to an embedded cabinet air-conditioning and refrigeration system for heat dissipation in a data center. Background technique [0002] With the rapid development of today's data computing technology, the heat generation of heat-generating equipment such as switches and servers is increasing; on the other hand, the miniaturization and cabinetization of heating equipment; concentrated. Under such conditions, the refrigeration system in the computer room is under increasing test. The traditional computer room air conditioner is a technology that appeared in the 1960s, which solved the heat dissipation problem of the program-controlled switch room at that time, and the thermal power of a single cabinet was less than 4kW. But at present, this technology can no longer meet the needs of modern data centers. The main reasons are: (1) The traditional computer room air conditioner adopts whole-are...

Problems solved by technology

But at present, this technology can no longer meet the needs of modern data centers. The main reasons are: (1) The traditional computer room air conditioner adopts whole-area cooling and cooling, and the cold energy is delivered to the room, and then the cold air can participate in the cabinet after heat exchange with the cabinet. The heat exchange of internal heating equipment, so the heat exchange efficiency is low, the overall cooling efficiency of the computer room is low, and the PUE value standard of the green data center cannot be reached; (2) The cooling capacity density of the air conditioner in the traditional computer room is too low, and a large amount of air conditioning equipment is required, and the user invests at one time (3) Since the computer room air conditioner adopts the whole-area cooling method, even if a large number of units are added, it still cannot meet the cooling needs of medium and high-density cabinets, and local overheating problems are prone to occur, and local overheating problems are difficult to solve by blindly increasing the total cooling load ; (4) In almost all traditional computer rooms, including low-density communication exchange rooms, there will be local overheating problems at the far end (away from the air conditioner side of the computer room)
