Description
One, technical field
The present invention relates to automation control area, specifically relate to a kind of energy-saving method for intelligently controlling temperature of network communication computer room.
Two, background technology
Popularize and the development of broadband technology several thousand up to ten thousand at most at least of the network nodes of each large and medium-sized enterprise and universities and colleges along with Internet and Intranet.Because therefore instruction and office district and students' dormitory district information access point comparatively dense that the characteristic (is the longest 100m of netting twine information transmission range of transmission medium with the copper core) of broadband network and campus network cover all are provided with several unattended network convergence device machine rooms (LA Management Room) in each building.The common relative closure of this class machine room, the heat insulating ability of machine room building structure is also better, cause the network active equipment accumulation caloric value of machine room very big thus, such machine room unmanned at ordinary times in addition, how to ensure the operation of the network equipment, the operating temperature of maintenance machine room is relatively stable to be a key factor.Usually the cold method of single air conditioning mechanism is mostly adopted in the temperature control of the unattended network equipment machine room of this class, and there is following problem in the method for the cold cooling of single air conditioning mechanism that the control of traditional building environment temperature is adopted:
1. consumed a large amount of electric energy.
2. use air conditioner to shorten service life of air conditioner for a long time, increased the maintenance workload of air conditioner simultaneously, make the network O﹠M workload heighten.
Three, summary of the invention
The objective of the invention is to overcome the problem that the cold cool-down method of single air conditioning mechanism that building environment temperature control tradition adopted exists, not only easy but also method for saving energy of a kind of network computer room temperature control is provided.This method uses outdoor natural environment as low-temperature receiver, make full use of the outdoor natural temperature and the indoor temperature difference, directly outdoor cold air is imported machine room based on ventilating fan and reduced room temperature, with air conditioner refrigeration is the mode of assisting, alternately enable the cooling of VMC or air conditioner refrigeration automatically, reached the service life that not only ensures the temperature of network equipment work but also prolonged air conditioner, and the remarkable effect of saves energy.
The technical scheme of realization goal of the invention is solved by following steps.
Energy-saving method for intelligently controlling temperature of network communication computer room is pressed Fig. 1 program flow diagram, and the step of its method is as follows:
Step 1: initialization, set the limit value T of outdoor temperature controller respectively
Hout, the limit value T of the temperature controller of air exchange system
Hin, the limit value T of the temperature controller of air conditioner
Kin
Step 2: the temperature that the outdoor temperature sensor measuring chamber is outer;
Step 3: the limit value T of outdoor temperature value and outdoor temperature controller
HoutRelatively, as if the limit value T of outdoor temperature value less than outdoor temperature controller
HoutThen forward step 4 (show that the temperature control in the machine room should bear) to, otherwise forward step 8 (show that the temperature control in the machine room should bear) to by air conditioner by air exchange system;
Step 4: enable air exchange system, obtain the indoor temperature value of the temperature sensor measurement of air exchange system;
Step 5: the limit value T of the indoor temperature value and the temperature controller of air exchange system
HinRelatively, as if the limit value T of indoor temperature value greater than the temperature controller of air exchange system
HinThen forward step 6 to, otherwise forward step 7 to;
Step 6: start ventilation electric fan ventilation cooling, forward step 5 then to;
Step 7: the electric fan work that stops to take a breath forwards step 2 to;
Step 8: enable air conditioner system, obtain the indoor temperature value of the temperature sensor measurement of air conditioner;
Step 9: the limit value T of the indoor temperature value and the temperature controller of air conditioner
KinRelatively, as if the limit value T of indoor temperature value greater than the temperature controller of air conditioner
KinThen forward step 10 to, otherwise forward step 11 to;
Step 10: start the air conditioner refrigeration cooling, forward step 9 then to;
Step 11: stop air conditioner system work, forward step 2 to.
The basic principle of energy-saving method for intelligently controlling temperature of the present invention is as follows:
According to Office of the Telecommunications Authority's analysis of statistical data for many years, the operation cost of the communications industry mainly is a power consumption cost, and in power consumption cost, the power consumption of air conditioner in machine room accounts for total power consumption more than 50%.One of energy-saving and cost-reducing effective ways are exactly the service time that reduces the air conditioner of highly energy-consuming as far as possible, rationally utilize outdoor natural cold source, and the ventilator of use low-power consumption as much as possible directly drains into the heat that internal home network equipment produces outdoor.Most of area in China, the period outdoor environment temperature is lower sooner or later winter, spring, 3 seasons of autumn and summer in 1 year, even the operating temperature that needs far below equipment in the machine room.Therefore under the prerequisite that does not influence building environment, actual conditions according to the machine room internal and external temperature are suited measures to differing conditions in terms of time, making full use of the outdoor natural environment of machine room is low-temperature receiver, when outside air temperature lower to a certain degree the time than indoor temperature, rely on ventilator that the heat in the machine room is taken away, realize that indoor heat radiation is to reduce the machine room indoor temperature; When outside air temperature, is forced to enable the air conditioner refrigeration cooling and reached the needed temperature of equipment steady operation with the temperature that keeps equipment machine room when high than indoor.Can reduce the service time of air-conditioning greatly like this, thereby reduce power consumption significantly, prolong the service life of air conditioner, reach energy saving purposes.Its workflow is as shown in Figure 1:
The energy-saving method for intelligently controlling temperature of the present invention following beneficial effect of having compared with the cold cool-down method of traditional single air conditioning mechanism:
1. when the temperature that keeps network communication computer room is relatively stable, greatly reduce the service time of air conditioner, prolonged the service life of air conditioner, reduced the maintenance workload of air conditioner.
2. reduce the service time of air conditioner, thereby reduce power consumption significantly, reach energy saving purposes, comparable traditional cold cool-down method of single air conditioning mechanism is saved the electric energy of 50%-70%.
3. the automaticity of this method is higher, can keep the temperature of network communication computer room relatively stable, can reduce the manpower consumption of manual intervention again, simultaneously in the future this class network communication computer room running environment being realized that remote monitoring and administration provides good basis.
