Description

Intelligent natural cold source energy-saving system

Technical Field

The utility model relates to a cold heat exchange technical field especially relates to a natural cold source economizer system of intelligence in natural cold source room.

Background

The intelligent natural cold source energy-saving system performs indoor cold and heat exchange by introducing the natural cold source, and stops the air conditioner from working under the condition that the natural cold source and the heat source meet the temperature energy requirement of an application scene, so that the service life of the air conditioner with the compressor is shortened, the power consumption with relatively high power consumption and low energy efficiency ratio is greatly reduced, and the energy conservation and consumption reduction are realized. Particularly, a natural cold source is introduced into the machine room to replace an air conditioner of the machine room to work under the condition that the outdoor temperature is lower than the temperature of the machine room, and it needs to be explained that the communication machine room needs to be refrigerated and cooled all the year round in partial areas due to the fact that the heat productivity of equipment in the machine room is very high, and the safety of the operating temperature of the communication equipment is ensured. The air conditioner energy-saving technical solution is widely applied by communication operators, and has obvious energy-saving effect through actual use. And with the increase of the integration level of production equipment of machine rooms such as data centers and the like, the heat load per unit area is multiplied, the heat load of an original cabinet is about 2-4kw, and the heat load of the existing high-density cabinet can reach 15-40 kw. Therefore, the requirements of energy conservation and consumption reduction of the air conditioner in the machine room are more and more shown. The future energy-saving solution can be applied to a wide application scene with all communication rooms such as electric power, radio and television, railways, banks and the like.

Some problems are found in the practical use process of the energy-saving intelligent natural cold source energy-saving system, the existing products and the technology thereof. The main problems are the following:

2. The reason for influencing the reduction of the cooling capacity in the running process of the natural cold source system is mainly caused by the reduction of the indoor and outdoor temperature difference, the increase of the filter pressure difference and the like. According to heating and ventilation professional knowledge, fan air supply volume and air supply distance are decided by the required full pressure, static pressure, excess pressure of fan, and after air filtration system blockked up, cause the pressure differential increase of filter both sides, this tendency must consume more fan static pressure to cause the fan air supply volume to reduce, the natural cold source refrigeration volume that must send into reduces. Therefore, the refrigeration requirement is not met, the pressure value of the fan is increased in the traditional method, the power consumption of the whole energy-saving equipment is increased, and the energy-saving rate is reduced. The cost of the fan is proportional to the power of the fan, which increases the cost of the equipment. Meanwhile, the problem that the production cost is increased due to the increase of the volume of equipment, the transportation cost is increased, the installation cost is increased, and the noise is increased is caused due to the increase of the fan. Especially for the scenes such as whole machine rooms, base stations and outdoor cabinets with high space utilization rate, the situation of dilemma is caused, the equipment volume needs to be increased in order to ensure the refrigerating capacity to meet, and the application scenes have or not space installation of equipment with large volume.

3. The traditional natural cold source takes the filter final resistance value as an air volume calibration point for fan pressure design, namely the pressure change values of the filter initial resistance value and the filter final resistance value have a change rate of 40-60%. This results in very large variations in the air flow throughout the operation. The refrigerating capacity is also changed proportionally. In order to overcome the change, the fan needs to adopt a variable speed fan, which causes complex control, and meanwhile, the cost of the variable speed fan is higher than that of a constant speed fan. Due to the increase of control complexity, on one hand, the cost is increased, and meanwhile, the number of fault points is increased, so that the later maintenance, use and operation are not facilitated.
