Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically a central temperature control system for a main control room. Background Technology

[0002] In the past, workshops requiring centralized temperature control used traditional Freon water-cooled air conditioning systems. The disadvantages of this system are that water-cooled Freon air conditioning consumes a lot of electricity; copper pipes in the cooler become clogged, requiring a clean water circulation system, which has high requirements for water quality; maintenance costs are high, and repair time is long once a failure occurs. Utility Model Content

[0003] The purpose of this invention is to provide a central temperature control system for the main control room that has a reasonable structure, adopts a direct air-cooling mode, and has a good cooling effect, in order to address the above-mentioned shortcomings.

[0004] The technical solution of this utility model is: a central temperature control system for a main control room, including a No. 1 booster fan and a No. 2 booster fan arranged outside the main control room; the No. 1 booster fan is connected to an upper air duct, which is connected to the main control room air duct, and the main control room air duct has a lower air outlet blowing towards the No. 1 electrical cabinet row, and the high-temperature air that has absorbed heat is discharged from the exhaust vents on both sides of the main control room; the No. 2 booster fan is connected to a lower air duct, which is connected to the main control room air duct, and the main control room air duct has an upper air outlet blowing towards the No. 2 electrical cabinet row, and the high-temperature air that has absorbed heat is discharged from the exhaust vents on both sides of the main control room.

[0005] The advantages of this utility model are: 1. It completely eliminates the original circulating system and compressor, and adds a large booster fan to the equipment arranged in the main control room, adopting a direct air-cooling mode, which has a good cooling effect. This not only reduces daily maintenance and upkeep costs, but also greatly reduces the investment of maintenance personnel and the consumption of spare parts. 2. With less equipment investment, it is possible to achieve a reasonable temperature range in a centrally controlled environment.

[0006] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0007] Figure 1 This is a simplified structural diagram of the present invention. Detailed Implementation

[0008] See Figure 1 The component names are as follows: 1# booster fan 1, 2# booster fan 2, upper air outlet 3, lower air outlet 4, upper air duct 5, lower air duct 6, main control room 7, air conditioning room 8, exhaust outlet 9, 1# electrical cabinet row 10, 2# electrical cabinet row 11.

[0009] See Figure 1A central temperature control system for a main control room includes a #1 booster fan 1 and a #2 booster fan 2 located outside the main control room 7. The #1 booster fan 1 is connected to an upper air duct 5, which in turn connects to the main control room air duct. The main control room air duct has a lower air outlet 4 blowing towards the #1 electrical cabinet row 10. High-temperature air absorbing heat is discharged from exhaust outlets 9 on both sides of the main control room 7. The #2 booster fan 2 is connected to a lower air duct 6, which in turn connects to the main control room air duct. The main control room air duct has an upper air outlet 3 blowing towards the #2 electrical cabinet row 11. High-temperature air absorbing heat is discharged from exhaust outlets 9 on both sides of the main control room 7. The equipment in the main control room 7 is concentrated and extends along both sides of the room. The equipment generates a lot of heat during operation, causing the room temperature to rise and affecting the safe and stable operation of the equipment. Therefore, cooling is required for the #1 electrical cabinet row 10 and the #2 electrical cabinet row 11 (two rows of electrical cabinets), hence the dual air duct system: upper air duct 5 and lower air duct 6. Cold air is blown from the No. 1 booster fan, through the upper air duct 5 (main control room No. 1 air duct), and the lower air outlet 4, upwards to above the No. 1 electrical cabinet row 10. The hot air, having absorbed heat from the distribution cabinet, is discharged to the outside through the exhaust outlets 9 on both sides of the main control room 7. Similarly, cold outdoor air is blown from the No. 2 booster fan, through the lower air duct 6 (main control room No. 2 air duct), and the upper air outlet 3, upwards to above the No. 2 electrical cabinet row 11. The hot air, having absorbed heat, is discharged to the outside through the exhaust outlets 9 on both sides of the main control room 7.

[0010] The equipment is installed in the original air-conditioning room 8, 7 floors below the main control room. The ambient temperature here is low, which saves the operation of 4 25-horsepower compressors compared to the original equipment. Each compressor has a power of 22KW, and can save 2112 kWh of electricity per day.

[0011] Working principle: Booster fans 1 and 2 pressurize outside cold air and deliver it through upper and lower air ducts 5 and 6 into the main control room 7. The air is then evenly distributed and blown onto electrical cabinets 10 and 21 via upper and lower air outlets 3 and 4. The hot air, having absorbed heat from the cabinets, is then exhausted from the exhaust outlets 9 on both sides of the main control room 7. This achieves the purpose of reducing the temperature inside the main control room 7. Actual measurements show that the indoor temperature can be controlled within the allowable temperature range of the equipment.

[0012] The above description is merely a specific embodiment of this utility model, and the various examples do not constitute a limitation on the substantive content of this utility model.
