High-energy-efficiency-ratio machine room air conditioning system

Abstract

The invention relates to a high-energy-efficiency-ratio machine room air conditioning system. The high-energy-efficiency-ratio machine room air conditioning system comprises an indoor unit, an outdoorunit and a control unit, the indoor unit is in fluid communication with the outdoor unit through a refrigerant pipeline, and the indoor unit comprises a heat pipe evaporator, a refrigerant flow adjusting device, an indoor fan and a mechanical refrigerating device; the mechanical refrigerating device comprises a compressor, an evaporator, a condenser and a throttling device; and the outdoor unit comprises a heat pipe condenser and an outdoor fan. According to the high-energy-efficiency-ratio machine room air conditioning system, the heat pipe technology is perfectly embedded into a traditionalcompressor refrigeration system, so that the energy efficiency ratio of the compressor is remarkably increased, a natural cold source and a mechanical cold source are in seamless butt joint, the natural cold source is utilized more sufficiently while the system reliability is improved, so that the system has the high energy efficiency ratio, and PUE of a data machine room is reduced.

Description

technical field [0001] The present invention relates to a computer room air conditioning system, more specifically, the present invention relates to a high energy efficiency ratio computer room air conditioning system. Background technique [0002] To meet the requirements of national planning, the data center system faces challenges. The cooling system is an area where data centers are currently relatively easy to achieve greater performance improvements. In order to reduce the running time of mechanical refrigeration and maximize the use of natural cooling sources (FreeCooling), the industry has made attempts in various aspects such as air cooling, water cooling, liquid cooling, engineering, operation and maintenance, and control. It has been verified that the natural fresh air + auxiliary refrigeration technology has requirements for the air quality of the operating site. Although the energy efficiency is relatively high, the management is complicated; the chiller + plat...
