Full-time natural cooling integrated cabinet-level air conditioner

Abstract

The invention discloses a full-time natural cooling integrated cabinet-level air conditioner. The full-time natural cooling integrated cabinet-level air conditioner comprises a directional cooling cabinet and a distributed air processing unit which are distributed up and down; the directional cooling cabinet comprises a closed same-stroke heat channel and a server installation space; the distributed air processing unit comprises a cabinet body, and an air return port and an air supply port are formed in the cabinet body; a heat exchange assembly is arranged in the cabinet body; an air outlet of the server installation space is in communication with the air return port through a closed same-stroke hot channel; and the air supply port is in communication with an air inlet of the server installation space through an open cold channel. According to the full-time natural cooling integrated cabinet-level air conditioner, the integrated air conditioner structure is used, multiple links in the concentrated refrigeration process are reduced, the refrigeration system is simplified, and the comprehensive manufacturing cost is reduced; and according to the full-time natural cooling air conditioner structure, the refrigeration efficiency of the air conditioner is greatly improved, and due to the distributed refrigeration mode in the distributed air treatment unit, the application range of the integrated cabinet-level air conditioner is expanded to several cabinets to thousands of cabinets, and low PUE can be achieved.

Description

technical field [0001] The invention belongs to the field of air conditioners, and relates to a cabinet-level air conditioner for a machine room, in particular to an integrated cabinet-level air conditioner with full-time natural cooling. Background technique [0002] As the heat density of a single server cabinet becomes higher and higher, cooling methods and airflow organization changes become more and more diverse. There are two main traditional cooling methods: one is the room-level direct expansion precision air conditioner, which usually adopts the method of underfloor air supply, hot aisle and cold aisle rational layout. The heat dissipation requirement below 4kW, and because of its low cooling efficiency, it is only used in small-scale DC equipment rooms; another way is centralized water-cooled room-level and inter-row air conditioners, compared to room-level direct expansion precision air conditioners Centralized cooling has been realized, and the cooling efficienc...
