Water-cooling-heat-pipe dual-mode machine room air conditioner

Abstract

The invention relates to a water-cooling-heat-pipe dual-mode machine room air conditioner. The water-cooling-heat-pipe dual-mode machine room air conditioner comprises a heat pipe heat exchange tail end system and a compressor refrigerating system; the heat pipe heat exchange tail end system comprises a heat pipe heat exchanger and a first throttling valve; the first throttle valve is mounted at a refrigerant inlet of the heat pipe exchanger; a compressor evaporator, a compressor, an inlet A of a double-medium heat exchanger refrigerant, a refrigerant outlet of the double-medium heat exchanger and a second throttling valve are sequentially connected through pipelines to form the compressor refrigerating system; a refrigerant inlet D of the double-medium heat exchanger is communicated with an outlet of a third throttle valve; an inlet of the third throttle valve is communicated with a refrigerant input pipe; and a refrigerant outlet C of the double-medium heat exchanger is communicated with a refrigerant output pipe.

Description

technical field [0001] The application relates to the technical field of refrigeration and air conditioning, in particular to a water-cooled heat pipe dual-mode computer room air conditioner. Background technique [0002] With the rapid development of my country's communication industry, the energy consumption and energy-saving problems of the computer room need to be solved urgently, and the new technology of using heat pipe technology in the air-conditioning and energy-saving of the communication computer room and the information center computer room, with its high efficiency, energy saving and green environmental protection, has triggered Widespread concern. [0003] However, the cooling capacity of the heat pipe system is easily affected by the outdoor temperature of the computer room. When the outdoor temperature of the computer room is higher, the cooling capacity of the heat pipe system will be worse, that is, the temperature in the computer room that the heat pipe sys...

Problems solved by technology

However, there is also a major problem in the air-conditioning mode that uses this heat pipe system and the conventional mechanical compression refrigeration and air-conditioning joint operation: the compressor system must be independent from the heat pipe heat exchange system, so it is also necessary to connect the cold source with them. Independent, resulting in high energy consumption of the cooling system of the data center in the computer room, and large construction investment
