Rack-mounted air-conditioner used in cabinet-type data center

Abstract

The invention discloses a rack-mounted air-conditioner used in a cabinet-type data center. The rack-mounted air-conditioner comprises an outdoor unit used for refrigeration, and an indoor unit connected with the outdoor unit and used for placing of electric equipment and supplying cold air to the electric equipment, wherein an air supply device used for providing air for the electric equipment in a circulating manner is arranged in the indoor unit; the indoor unit is arranged in the bottom of the cabinet body of the air-conditioner and is communicated with a cold air sealed passage, so as to convey cold air into the cabinet body of the air-conditioner to cool the electric equipment, and keep the temperature in the cabinet body of the air-conditioner at a proper degree. The rack-mounted air-conditioner has the advantages that accurate cold air supply is realized; the air supplying distance is shortened to reduce extra energy loss.

Description

technical field [0001] The invention relates to the field of computer room air conditioners, in particular to a rack-mounted air conditioner capable of accurately supplying air and shortening the air supply distance for a rack-mounted data center. Background technique [0002] The current rack-type data centers are generally of the front-to-back ventilation type, and external air conditioners are used to cool the electrical equipment in the racks. However, the data center has high requirements on the temperature, humidity and cleanliness of the computer room. The external air conditioner needs to cool the entire computer room to maintain the normal operation of the electrical equipment in the data center cabinet. Especially when the computer room has a large space, the energy consumption is higher; In order to maintain a certain temperature and humidity in the computer room, the air conditioner needs frequent cooling, humidification, dehumidification and heating, which consu...

AI Technical Summary

Problems solved by technology

The main disadvantages of these methods are: the built-in integrated air conditioner, because the air conditioner is integrated indoor and outdoor, the air conditioner structure is very compact, resulting in a large resistance on the wind side, large fan power consumption, and the air conditioner has a small cooling capacity and low cooling efficiency. Difficult to maintain; split indoor unit on the top, the cooling capacity of the air conditioner is relatively small, and the condensed water of the air conditioner is easy to overflow, there is a risk of flooding, and it is easy to damage expensive electrical equipment, and the air conditioner is heavy, so it is inconvenient to maintain if it is placed on the side; Or install the air conditioner on the back, which seriously affects the wiring in the cabinet, occupies the area of ​​the machine room, increases the size of the cabinet, and is inconvenient for elevator transportation
