Machine room heat dissipation system with heat recovery/full natural cooling and control method of machine room heat dissipation system

Abstract

The invention provides a machine room heat dissipation system with heat recovery / full natural cooling. The machine room heat dissipation system comprises a full natural cooling system, a heat recovery system and a control system. The full natural cooling system comprises a cooling unit, a cooling water pump, a liquid cooling system and a gas cooling system. The liquid cooling system and the gas cooling system are connected in parallel through a pipeline and are connected with the cooling unit. The heat recovery system comprises a water source heat pump unit, a heat source pump and a heat utilization device, all of which are connected with the cooling unit in parallel. The heat utilization device, the heat source pump and the water source heat pump unit are sequentially connected to form a circulation loop. The heat utilization device comprises an absorption refrigerator and a heating tail end which are connected in parallel. The control system is used for controlling the full natural cooling system and the heat recovery system to work. The invention further provides a control method of the above machine room heat dissipation system. According to the machine room heat dissipation system and the control method of the machine room heat dissipation system, a liquid-gas double-channel refrigerating technology is used for achieving data center natural cooling, the heat recovery system is used for recovering liquid-gas double-channel dissipated heat, and data center energy can be reasonably, efficiently and flexibly used.

Description

technical field [0001] The invention relates to a heating and cooling system for a computer room, in particular to a cooling system with heat recovery / full natural cooling for a computer room and a control method thereof. Background technique [0002] According to statistics, my country's data center energy consumption accounts for about 1.8% of the country's total energy consumption, which is equivalent to the annual power generation of the Three Gorges Hydropower Station of about 100 billion kWh. However, a large amount of energy is wasted by the cooling system (as high as 40% to 50%, and the PUE value is generally higher than 2.2), which seriously restricts the green and sustainable development of data centers. [0003] The core of solving the problem of high energy consumption and high waste in data centers is to reduce or even eliminate air conditioners. The compressor is the main power-consuming part of the air conditioning system, so how to reduce the running time of...

Problems solved by technology

Although this invention provides a method for recovering waste heat in a computer room, this method can only heat liquid or gaseous media to provide hot water or hot air, and can only be used for heating in winter

In addition, in this solution, both liquid cooling and air cooling use compressors, which consumes a lot of energy and causes a great waste of resources
