Description
Technical field
The present invention relates to a kind of apparatus of air conditioning and run intelligence control system and method, belong to communications equipment room air-conditioning technique field.
Background technology
Along with country is to the restructuring of communications industry infrastructure, set up steel tower company, three common carriers, the infrastructure of communication, UNICOM and telecommunications incorporates steel tower company into and is about to complete on August 31st, 2015.The communications equipment room of all three common carriers also will incorporate steel tower company in the lump, and the equipment of three operators can be concentrated and use existing machine room, and in machine room, the auxiliary facility such as power supply, air-conditioning also will be integrated.Integrate the input forming and new departure of employing new technology is reduced equipment, reach the energy-saving and cost-reducing object reducing expenditure.
In communications equipment room, the usual using air-condition of temperature controls, the normal temperature generally used for temperature in machine room, namely between 20-25 DEG C, main is exactly be battery service, because be easy to dehydration higher than 25 DEG C of batteries, very large to the aging effects of battery, and the cost of equipment of battery is relatively high, so in order to generally temperature in machine room be adjusted to about 25 degree by air-conditioning the service life ensureing battery.By statistical computation, in annual base station, the power consumption of air conditioner refrigerating is close to 50% of base station total electricity consumption, considerable amount.Therefore, when ensureing that base station equipment can normally work, reducing air-conditioning and using, the energy loss that reduction air conditioner refrigerating brings and the work of minimizing base station maintenance will become an important research direction of the energy-saving and emission-reduction of steel tower company.
Inventor finds in the process of research, and the current configuration possessing the communication base station of machine room condition and deployment scenario, mainly contain following technical problem:
1, equipment especially battery in machine room, comparatively responsive to temperature, therefore in machine room, temperature controls usually at about 25 DEG C.According to rough calculation, in annual machine room, the power consumption of air conditioner refrigerating accounts for 50% of whole machine room power consumption;
2, base station air conditioner mostly is operation in 7 × 24 hours, is therefore suitable for not needing heating in indoor temperature, when freezing, the power consumption of air-conditioning self has just become unnecessary energy resource consumption.And once after have selected air conditioning operating mode (freeze, heat or automatically), whether air-conditioning can only reach this kind of pattern of desired temperature according to return air temperature controls, control mode is simple, cannot meet the demand that machine room energy-saving reduces discharging;
3, in order to save air conditioning electricity cost, every year along with seasonal variations needs, repeatedly to scene, base station adjustment running state of air conditioner and parameter, to need to consume a large amount of human and material resources resources;
4, lack of refrigerant, evaporimeter or the condenser heat radiation problem such as not smooth occurred in operation of air conditioner process often can not Timeliness coverage, causes the improper power consumption of air-conditioning to increase;
5, the defencive function that carries of air-conditioning is single, during the cracking of Alternating Current Power Supply index (as large in phase shortage, voltage pulsation etc.), very easily bring out the faults such as compressor of air conditioner damage, add maintenance cost;
6, air-conditioning built-in return air temperature sensor accuracy of detection is poor, and base-station environment temperature and setting require that deviation is comparatively large, can not meet base-station environment requirement or cause air-conditioner power consumption to increase;
7, current in the machine room of the energy-saving equipments such as the new wind of installation, usually adopt energy-saving equipment together with the operational mode of air-conditioning, control poor reliability, the situation that the new wind of frequent appearance, air-conditioning run simultaneously, add idle call electricity on the contrary;
8, domestic three common carriers are in network operation macro base station quantity more than 1,500,000, and Urban Annual Electrical Power Consumption amount is quite large;
9, in process machine room integrated in steel tower company, the battery of part machine room probably replace by new case, namely no longer battery is installed in machine room, so there is no necessity and maintain computer room temperature again at 20 ~ 25 DEG C, 30 ~ 40 DEG C can be brought up to, even higher;
10, machine room is at the air-conditioning of operation at present, and usual adjustable temperature scope is 17 ~ 30 DEG C, and the room temperature that cannot reach more than 30 DEG C controls;
Based on foregoing description, under the prerequisite ensureing reasonable temperature in machine room, how to reduce air-conditioner operation time, reduce air-conditioning maintenance, reducing machine room energy loss is the technical problem run at present.
