Combined fresh air thermostatic cooling system special for machine rooms and base stations

Abstract

The invention discloses a combined fresh air thermostatic cooling system special for machine rooms and base stations. The system comprises an intake device, an exhaust device, a temperature sensor and a central processing unit, wherein the intake device, the exhaust device, the temperature sensor and the central processing unit are mounted on a wall. The intake device comprises an outdoor air inlet, an intake fan, a filter, two pieces of water curtain cloth, a spray pipe, and an indoor air outlet, which are arranged in sequence. The exhaust device comprises an indoor air inlet, an exhaust fan and an outdoor air outlet, which are connected in sequence. The spray pipe is disposed at the top of spacing reserved between the two pieces of water curtain cloth. A plurality of mist nozzles are arranged at the lower end of the spray pipe. A plurality of water incoming pipes are connected to a water inlet of the spray pipe. Each water incoming pipe is provided with an electric control valve. The signal output end of the temperature sensor is correspondingly connected with the signal input end of the central processing unit. The control signal output end of the central processing unit is connected with the control end of the electric control valve. Compared to the traditional water-curtain fresh air systems, the combined fresh air thermostatic cooling system special for machine rooms and base stations has higher cooling efficiency since mist easily evaporates.

Description

technical field [0001] The invention relates to an indoor air cooling system, in particular to a composite fresh air automatic temperature-regulating cooling system for machine rooms and base stations. Background technique [0002] In the existing technology, equipment rooms and base stations mostly adopt air-conditioning and refrigeration methods, which cause high noise, internal circulation of indoor air, little use of fresh air, no use of staff retention, and high energy consumption of the system. Such shortcomings not only inhibit the development of air-conditioning systems, but are also not conducive to the development of base stations. , The energy saving of the computer room reduces the air conditioning energy efficiency ratio of the base station and the computer room. There are also some computer rooms and base stations that are cooled by the fresh air system, that is, the inlet and outlet fans are installed on the walls of the room, and the outdoor fresh air is int...

Problems solved by technology

[0002] In the existing technology, equipment rooms and base stations mostly adopt air-conditioning and refrigeration methods, which cause high noise, internal circulation of indoor air, little use of fresh air, no use of staff retention, and high energy consumption of the system. Such shortcomings not only inhibit the development of air-conditioning systems, but are also not conducive to the development of base stations. , The energy saving of the computer room reduces the air conditioning energy efficiency ratio of the base station and the computer room

There are also some computer rooms and base stations that are cooled by the fresh air system, that is, the inlet and outlet fans are installed on the walls of the room, and the outdoor fresh air is introduced into the room for heat exchange and then exhausted to the outside. Although this method introduces fresh air, the cooling effect is very poor. , is also not conducive to indoor temperature regulation

[0003] The applicant also applied for a patent for the water curtain fresh air system, adding a water curtain on the basis of the fresh air system, allowing part of the water to evaporate and absorb heat when the wind passes through the water curtain, thereby reducing the temperature of the air entering the room, and the cooling efficiency is effectively improved. Improvement, but the water on the water curtain is adsorbed on the curtain fabric, and its evaporation efficiency is not high enough, so the cooling efficiency of the water curtain fresh air system can be improved
