Description

Machine room energy-saving system
Technical field
The present invention relates to field of air conditioning, especially relate to a kind of machine room energy-saving system of data center.
Background technology
All the time, the work that exists for us and the life of data center have brought facility, but as far as data center owner, keep the required huge energy spending of the normal operation in service data center and let them feel worried always.Such as, to calculate according to general standard, the energy consumption of data center is 100 watts/square feet, the peak value radiating requirements amount of so general 20000 square feet enterprise data center is equivalent to the demand of one 200000 square feet ShangWu Building; Year total energy consumption then is equivalent to the energy consumption in 400000 square feet of business office buildings.
At the traditional data center; The client is in order to ensure maximized running time, the infrastructure construction of the redundant power of having to frequently carry out, except the power consumption of equipment selfs such as server, storage, network increasing year by year; The quantity of these information technoloy equipments increased because of the business expansion in every year; The continuous lifting of performance of these equipment simultaneously also causes unit power consumption to increase, and has suitable temperature for guaranteeing data center, makes information technoloy equipment normally to move; The power consumption of equipment such as air conditioner refrigerating is also rising with surprising speed--do not passing through in the improved green of green energy conservation; Data show that in the spent electric weight of data center, 50% electric energy is used to air conditioner refrigerating nearly.
This shows, the instant moment has been arrived in the green energy conservation adjustment at data center.The third party investigates the company data prediction, if energy-conservation adjustment is not carried out at the data center, in the five-year, the enterprise above 90% can be because of meeting with the interruption that the power availability restriction cause data center's operation so; Have 25% data center so produce serious service disconnection.At present in conservation measures, utilize natural cooling source generally to be used, but in traditional data in the heart, need carry out omnibearing transformation to machine room, air-conditioning, rack, have the big characteristics of difficulty of transforming.
Summary of the invention
The present invention is directed to the deficiency of prior art, a kind of machine room energy-saving system of simple in structure, low cost of manufacture is provided, this system can make full use of natural cooling source, reduces the air-conditioning system load, the energy consumption of maximized saving air-conditioning system.
For realizing above-mentioned purpose; The present invention can take following technical proposals: the present invention includes two row's server cabinet and air-conditioning units; The back-to-back placement of said two row's server cabinets; Form the passage of heat of a heat supply airflow between the back side of two row's server cabinets, the said passage of heat is communicated with the air inlet of air-conditioning unit through the return air path, and the top of the said passage of heat is provided with heat exchanger; Said heat exchanger through water pipe with water pump, be arranged at outdoor natural water cooler and be communicated with, form a cooling water circulation loop; The two ends of the said passage of heat respectively are provided with airfast baffle plate, and the back side and the floor of the baffle plate at the two ends of the said passage of heat and heat exchanger lower surface, two row's server cabinets surround confined space; The top of said heat exchanger is provided with the return air branch road that is tightly connected with said return air pipeline, is provided with return air fan in the return air branch road.
Another aspect of the present invention, said natural water cooler comprise water coil and are used to promote the fan of the radiating rate of medium in the water coil.
Beneficial effect of the present invention is: the present invention is simple in structure, low cost of manufacture, environmental protection; Avoided the large-scale redevelopment of data center machine room; Through but closed circuit of nature water-cooled is set, made full use of natural cooling source, reduce the air-conditioning system load; The energy consumption of maximized saving air-conditioning system has very high practicality.
Description of drawings
Fig. 1 is the sketch map of machine room energy-saving system of the present invention.
The specific embodiment
In order to make those skilled in the art person better understand the present invention program; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the present invention's protection.
As shown in Figure 1, machine room energy-saving system of the present invention comprises that being arranged at two in the machine room 11 arranges server cabinet 1 and air-conditioning unit 2, and this air-conditioning unit 2 has air inlet 21 and air outlet 22; The 1 back-to-back placement of two row's server cabinets, the passage of heat 10 that the hot air flow that formation one supplies server to give out between the back side of two row's server cabinets 1 circulates, this passage of heat 10 is communicated with the air inlet 21 of air-conditioning unit 2 through return air path 4; Heat exchanger 3 is installed above the passage of heat 10, this heat exchanger 3 through water pipe 6 with water pump 8, be installed on outdoor natural water cooler 7 and be communicated with, form a cooling water circulation loop; The two ends of the passage of heat 10 respectively are equipped with an airfast baffle plate, and the back side and the floor of the baffle plate at the passage of heat 10 two ends and heat exchanger 10 lower surfaces, two row's server cabinets 1 surround a confined space; The return air branch road 9 that is tightly connected with return air pipeline 4 is equipped with in the top of heat exchanger 3, and a return air fan 5 is installed in the return air branch road 9.Nature water cooler 7 comprises water coil 71 and is used to promote the fan 72 of the radiating rate of medium in the water coil 71.
Operation principle of the present invention: as shown in Figure 1, arrow is represented the circulating direction of gas among the figure, and dotted line is represented hot blast, and solid line is represented cold wind; Under the lower situation of outdoor temperature; Be arranged on cold water in the outdoor natural water cooler in water pipe pumps to heat exchanger through pump handle, the cold water in the heat exchanger is taken away the heat that part of server is discharged, and the water that has absorbed heat is withdrawn into outdoor natural water cooler through an other water pipe; Cold air by outdoor cools off it; So circulation is carried out, and this cooling water circulation loop has reduced the temperature of the gas of server discharge effectively, and the hot blast after the return air fan in the return air branch road will be lowered the temperature pumps in the return air pipeline; Then being transported to the air-conditioning unit cools off; Cooled gas is discharged from the another one outlet of air-conditioning unit, gets into machine room, thereby the front of server cabinet is lowered the temperature.
Utilization of the present invention is arranged at outdoor natural cooling source the hot blast of server discharge is effectively lowered the temperature; Hot blast after the cooling reduces the load of air-conditioning system again by the air-conditioning system cooling, realizes purpose of energy saving; And avoided the large-scale redevelopment of machine room; Install simply, low, the environmental protection of cost has very high practicality.
