Description
技术领域technical field
本实用新型涉及空调系统技术领域，具体涉及一种一体化自然冷却机房空调系统。The utility model relates to the technical field of air conditioning systems, in particular to an integrated natural cooling machine room air conditioning system.
背景技术Background technique
近年来随着信息产业的快速发展，数据中心的数量和能耗大幅度增长。数据中心机房内的IT设备发热量巨大，现有机房空调大多全年依靠蒸气压缩制冷，制冷能耗一般占机房总能耗的30％以上。推广机房节能冷却方法已经成为迫切需求。自然冷却技术是指在室外气温较低的情况下利用室外冷空气等自然冷源冷却机房，是机房节能冷却的有效方法。分离式热管具有良好的传热性能，尤其适合作为机房自然冷却装置。然而，这种热管散热装置只能应用在室外温度低的场合，因此需要增加一套蒸气压缩制冷系统作为辅助，这就提高了初始投资，同时增大了占地面积。为此，一些现有专利提出了蒸气压缩和回路热管的复合机组。专利《一种带自然供冷供热功能的空气处理装置》(申请号：200910119883.7，公开号：CN 101514856 A)提出了一种带自然供冷供热功能的空气处理装置，实现了全年工作目的。然而，这种方案中蒸气压缩与自然冷却需要阀门切换，影响机组运行可靠性。专利《一种复叠机械制冷的液泵驱动热管装置及运行方法》(申请号：201210084797.9，公开号：CN 102607120 A)提出了一种复叠机械制冷的液泵驱动热管装置，但由于方案中蒸气压缩回路的蒸发器与热管回路的冷凝器相互独立，系统较为复杂。专利《一种一体化机房空调系统》(申请号：201320561006.7，公开号：CN 203605376 U)利用三介质换热器避免了阀门切换并简化了系统结构，但所用的空冷式三介质换热器的大规模设计制造存在难度。In recent years, with the rapid development of the information industry, the number and energy consumption of data centers have increased significantly. The IT equipment in the computer room of the data center generates a huge amount of heat. Most of the air conditioners in the existing computer room rely on vapor compression refrigeration throughout the year, and the cooling energy generally accounts for more than 30% of the total energy consumption of the computer room. It has become an urgent need to promote energy-saving cooling methods for computer rooms. Natural cooling technology refers to the use of natural cooling sources such as outdoor cold air to cool the computer room when the outdoor temperature is low. It is an effective method for energy-saving cooling of the computer room. The separated heat pipe has good heat transfer performance, and is especially suitable as a natural cooling device for a computer room. However, this heat pipe cooling device can only be used in places where the outdoor temperature is low, so it is necessary to add a set of vapor compression refrigeration system as an auxiliary, which increases the initial investment and increases the occupied area. For this reason, some existing patents have proposed the composite unit of vapor compression and loop heat pipe. The patent "An Air Handling Device with Natural Cooling and Heating Function" (application number: 200910119883.7, publication number: CN 101514856 A) proposes an air handling device with natural cooling and heating function, which realizes the year-round work Purpose. However, in this scheme, vapor compression and natural cooling require valve switching, which affects the operating reliability of the unit. The patent "A liquid pump-driven heat pipe device for cascade mechanical refrigeration and its operation method" (application number: 201210084797.9, publication number: CN 102607120 A) proposes a liquid pump-driven heat pipe device for cascade mechanical refrigeration, but due to the The evaporator of the vapor compression circuit and the condenser of the heat pipe circuit are independent of each other, and the system is relatively complicated. The patent "An Integrated Computer Room Air Conditioning System" (application number: 201320561006.7, publication number: CN 203605376 U) uses a three-medium heat exchanger to avoid valve switching and simplifies the system structure, but the air-cooled three-medium heat exchanger used It is difficult to design and manufacture on a large scale.
因此，需要提供一种一体化自然冷却机房空调系统，实现数据中心机房自然冷源的充分利用，同时简化系统结构和运行控制难度、提高系统稳定性和可靠性。Therefore, it is necessary to provide an integrated natural cooling computer room air-conditioning system to fully utilize the natural cooling source of the data center computer room, simplify the system structure and operation control difficulty, and improve system stability and reliability.

所述热管回路中还包括吸液芯，所述吸液芯内设有驱动制冷工质循环的毛细芯，所述热管冷凝器的安装高度低于热管蒸发器的安装高度。当热管回路的热管蒸发器6受热时，制冷工质迅速蒸发，蒸气在微小的压力差下流向热管冷凝器5，并且释放出热量，重新凝结成液体，液体再沿吸液芯的毛细芯靠毛细力的作用流回热管蒸发器6，如此循环不止，热量由热管蒸发器6一端传至热管冷凝器5一端，这样可以将热管冷凝器5的安装高度低于热管蒸发器6的安装高度，依靠毛细芯的毛细力驱动制冷工质的循环。The heat pipe circuit also includes a liquid-absorbing core, and the liquid-absorbing core is provided with a capillary core for driving refrigerant circulation, and the installation height of the heat pipe condenser is lower than that of the heat pipe evaporator.
