Description

Intelligent distributed air conditioning system

Technical Field

Background

With the construction of the 5G communication network, the heat dissipation problem of the communication equipment in the base station will be more severe. In order to ensure the normal operation of equipment, an air conditioner is often required to be installed in a base station machine room for cooling. The traditional cooling mode of equipment in a machine room is 'environment cooling before and equipment cooling after', namely, a centralized air treatment mode, cold air is sent into an indoor space from the tail end of an air conditioner, and cold energy is transmitted to the vicinity of the equipment so as to be sent into heating equipment for cooling. The heated hot air is then delivered to the indoor space and ultimately delivered to the air conditioning terminal for treatment.

The traditional cooling mode has a plurality of problems: firstly, the air supply distance from the tail end of the air conditioner to the cooling equipment is too long, and large airflow conveying power is needed; secondly, cold and hot air flows in the machine room are mixed, cold air is gradually lost in the transmission process, and in order to make up for the heat transfer loss, lower cold source temperature is often needed, so that higher refrigeration energy consumption is caused; in addition, communication equipment, transmission equipment, power supply equipment and other equipment are arranged in the machine room, the positions of the equipment are different, the heat productivity is different, the heat source distribution is not uniform, the air flow organization is disordered, the heat dissipation problem is not considered in the equipment layout, the distance between the equipment is possibly too compact, the problems that the equipment absorbs the heat discharged mutually and forms cold and hot air short circuit can exist, if the air outlet of the air conditioner is shielded by the equipment, the air flow short circuit can also occur, the air flow organization is lack of reasonable planning, and the cooling efficiency is seriously reduced; different equipment has different heat productivity and different heat quantity to be taken away, the required air supply quantity cannot be distributed according to the requirement, and local hot spots are easy to generate for high-heating-density equipment; the equipment far away from the air conditioner has a high temperature, and in order to meet the requirement of equipment cooling, the air conditioner needs to provide larger air volume and more cooling capacity, so that the problem of excessive cooling of a machine room can occur, and the energy consumption of the air conditioner is increased; in addition, in order to meet the development requirements of the network, equipment in the base station often faces elimination and replacement, and at the moment, the actual use scale of the equipment is inconsistent with the capacity of the air conditioning system.

Compared with the original communication equipment, the power consumption of the 5G communication equipment is higher, the deployment of the edge computing equipment can be considered in the construction of a future site, and the power density and the power consumption of the server can be greatly improved. The base station air conditioner needs to satisfy the heat dissipation demand of equipment on the one hand, avoids appearing local hot spot, and on the other hand needs the strict control refrigeration energy consumption, saves the charges of electricity spending, and the current air conditioner framework of base station will be unable to satisfy the heat dissipation demand of equipment in the construction of 5G in the future. Future air-conditioning architectures should meet the following requirements: firstly, directional cooling is required, and the air conditioning system is arranged according to the principle of 'cooling equipment first and cooling environment later', so that invalid cooling capacity waste is avoided, and the energy utilization rate is improved; secondly, the heat dissipation of the equipment is accurately controlled, cooling is realized according to needs aiming at different equipment types, dynamic adjustment is timely carried out along with the change of services and the actual power consumption of the equipment, the single-point needs are met, the integral optimization is realized, and the effective heat dissipation of the equipment and the efficient operation of an air conditioning system are guaranteed; the system operation should realize on-line monitoring and intelligent operation and maintenance, meet the requirements of rationality and economy of base station air conditioning system management, improve the operation and maintenance level and prolong the life cycle of equipment; the refrigeration capacity is required to be expanded as required, and the deployment of the base station air conditioner has the capacity of expanding the refrigeration capacity along with the development of the service volume, so that the actual heat dissipation requirement of equipment can be continuously met, and the phenomena of 'small horse' pulling 'of a cart' and continuous replacement of an air conditioning system are avoided; the requirement of uninterrupted cooling is met, and the problem of cooling interruption caused by air conditioning system faults is avoided.

Aiming at the problem of low refrigeration efficiency of a base station air conditioner, the currently adopted optimization method is to arrange a plurality of air conditioner terminals in a machine room and use a row-room air conditioner to enable the air conditioner terminals to be closer to equipment needing cooling, or a high-power fan is arranged on a machine cabinet provided with the equipment, so that the air flow passing through the equipment is increased to improve the cooling efficiency.

Although the existing improvement mode can relieve the problems of equipment overheating and high energy consumption of air conditioners to a certain extent, a relatively extensive centralized refrigeration mode is not changed, the problems of cold and hot air flow mixing and disordered air flow organization are not solved, and a large amount of cold energy is still lost in the machine room environment.
