An intelligent ventilation system for a base station computer room

technical field

The invention relates to a mobile communication base station, in particular to a ventilation control system of the base station.

Background technique

The current mobile communication base station computer rooms are fully enclosed computer rooms, and the power supply equipment, transmitting equipment, and transmission equipment in the computer room are all relatively large heating elements. It is necessary to maintain a certain working environment temperature in the computer room (the base station environmental standard GB50174-93 stipulates that the temperature of the base station is 18°C-28°C all year round, which is mainly achieved by air conditioning. The air conditioner is in operation (cooling) most of the time 365 days a year. Even in summer, sometimes the temperature at night is around 20°C (this temperature also meets the requirements for the working environment of indoor communication equipment), and the air conditioner is turned on. In this way, the outdoor low temperature in the three seasons of winter, spring, autumn and summer morning and evening can be beneficial for heat dissipation and cooling Conditions are ignored, resulting in unnecessary waste of electrical energy and high operating costs.

After using the above-mentioned technical solution: when the intelligent ventilation system is in automatic condition, if the indoor temperature is lower than the set lower limit value, the air conditioner will be turned off and the fan will be turned off. If the indoor temperature is higher than the set upper limit, the air conditioner is forced to be turned on and the fan is turned off. If the indoor temperature is higher than the lower limit but lower than the upper limit, the outdoor humidity is lower than the set value (such as 80%), and the outdoor temperature is lower than the upper limit of the indoor temperature, the fan will be turned on and the air conditioner will be turned off. Use indoor and outdoor temperature difference, forced ventilation and convection to dissipate heat. Make full use of natural resources, adjust the indoor temperature, and achieve the purpose of saving electricity and energy.

The air intake adopts a professional air filter, which can ensure the filtering effect. The filter screen is supported by a metal mesh surface, which can prevent deformation due to strong wind, and the filter screen adopts an integral frame, which is easy to clean, disassemble and reuse, and can also prevent wind pressure deformation and rat bites.

Invention effect

1. Effective use of natural resources, adjustment of indoor temperature, and reduction of power consumption.

2. While controlling the temperature of the base station, the air is also replaced to remove harmful gases and protect the health of maintenance personnel.

3. Shorten the working hours of the air-conditioning compressor and greatly prolong the working life of the air-conditioning system.

4. Intelligent switching between ventilation and air conditioning to ensure safe and reliable operation of the system.

Detailed ways

An intelligent ventilation system for a computer room base station, including a computer room 1 and a base station air conditioner installed in the computer room, a ventilator 2, a temperature sensor, a humidity sensor and a controller are also arranged in the computer room, and an air exhaust port is also arranged in the computer room , the exhaust outlet is downward and equipped with rainproof grille. The controller is connected with the ventilator and the base station air conditioner to control the opening or closing of the ventilator and the base station air conditioner. The ventilator 2 is installed at the bottom of the base station at a height of 40 cm from the ground. The ventilator 2 includes a motor 7 , a rotating shaft 5 and blades 4 . The filter screen 3 is installed on the front end of the blade 4 .

Specific working process: When the intelligent ventilation system is automatic, in winter, spring or night, when the temperature sensor finds that the indoor temperature is lower than the lower limit value we set, the air conditioner will be turned off and the fan will be turned off. If the indoor temperature is higher than the set upper limit, the air conditioner is forced to be turned on and the fan is turned off. If the indoor temperature is higher than the lower limit but lower than the upper limit, the outdoor humidity is lower than the set value (such as 80%), and the outdoor temperature is lower than the upper limit of the indoor temperature, the fan will be turned on and the air conditioner will be turned off. Use indoor and outdoor temperature difference, forced ventilation and convection to dissipate heat. When the outdoor ambient temperature is low, the fan can slowly supply air to form displacement ventilation, which can not only effectively remove the heat in the base station, but also remove various harmful gases in the room, make full use of natural resources, adjust the indoor temperature, and achieve power saving and energy saving. Purpose.

1. Air-conditioning and ventilation energy-saving system temperature control power At present, the cooling method of the base station is mainly carried out by air-conditioning refrigeration, and because the base station is in an unattended state, the temperature of the air-conditioning is generally constant between 18 and 25 degrees all year round. At present, the air conditioner used in the base station is generally 3 hp (2.58KW), and the intelligent ventilation system can also ensure the safe operation of the communication equipment of the base station, and its power is only 0.12KW.

2. Comparative analysis of economic efficiency The cooling capacity of 1 hp is 0.86KW, the working time of the unit is 24 hours/day, the independent working time is 210 days/year, and the compressor is working 80% of the time. When the intelligent ventilation system is used in conjunction with the air conditioner, the combined use time of the air conditioner is 90 days/year, the use time of the intelligent ventilation system is 180 days/year, and the electricity fee per degree (KW h) is 0.65 yuan. The analysis and calculation conclusions are as follows:

Originally used alone air conditioner (3 hp) annual electricity bill: 3×0.86×24×0.8×210×0.65=6761.66 (yuan)

Smart ventilation system used in conjunction with air conditioner Annual electricity cost:

(3×0.86×24×0.8×90×0.65)+(0.120×24×180×0.65)=3234.81 (yuan)

To sum up, if used in a base station computer room with high sensible heat load, the comprehensive solution of intelligent ventilation system plus air conditioner can save more than 60% of power consumption than using air conditioner alone, and each base station computer room can save about 3527 yuan per year. If calculated on the basis of 1,000 base station computer rooms, the use of intelligent ventilation and intelligent temperature control system can save 3.527 million yuan in electricity expenses every year.
