At present, power supply equipment, emission equipment, transmission equipment and the like in a telecommunication room are large heating bodies. The machine room is kept at a certain working environment temperature mainly by an air conditioner. In order to ensure that the equipment can work continuously and stably, the air conditioner is required to cool continuously without downtime due to overhigh temperature. From the energy consumption structure, saving the electricity used by the air conditioner is the most effective and potential method for realizing energy conservation in the communication industry.
The main energy-saving scheme of the current communication base station is to cool the base station by using an outdoor natural cold source in winter or transition seasons, and the following modes are mainly adopted: 1) fresh air system: directly introducing outdoor cold air and discharging indoor hot air. The method can directly utilize a natural cold source, but the fan has high energy consumption, the humidity is difficult to control, and the building structure is greatly changed; 2) adopting a dividing wall type heat exchanger: the heat exchange between the indoor hot air and the outdoor cold air is carried out by adopting a dividing wall type heat exchanger without directly introducing fresh air. The method has the advantages of low heat exchange efficiency, large maintenance amount and large modification on the building structure. 3) A secondary refrigerant heat exchanger: and the cold air is directly introduced into the fresh air, and the secondary refrigerant heat exchanger is adopted to exchange heat between the indoor hot air and the outdoor cold air. According to the method, the circulating pump is added, water is introduced into the machine room to cause possible leakage risk, and meanwhile, the circulating pump needs to be additionally powered, so that the energy-saving effect is reduced. 4) Refrigeration/heat pipe double circulation air conditioner: the air conditioning mode is adopted in the high-temperature season, and the heat pipe mode is adopted in the low-temperature season. The method has poor heat exchanger matching, can influence the energy efficiency of the system, needs an additional water pump and reduces the energy-saving effect.
Patent CN107421081A discloses a communication base station temperature control energy saving device, which sets a reference value for the temperature inside the communication base station through a converter, transmits the temperature inside the communication base station collected by a thermometer to the converter, and controls a compressor air conditioning unit to start working through a controller, and simultaneously, an indoor heat exchanger and an outdoor heat exchanger interact with each other to assist the compressor air conditioning unit to complete the adjustment of the temperature inside the communication base station.
