Dual system air conditioner for railway computer room

Abstract

The invention discloses a dual system air conditioner for a railway computer room. The dual system air conditioner comprises an indoor air conditioner unit and an outdoor air conditioner unit. The indoor air conditioner unit comprises two compressors, two multipliers, an evaporator, an evaporator fan and a condensate water pan. The compressors are connected with the evaporator. The multipliers are connected with the condensate water pan and are arranged at outlets of the compressors. The evaporator fan is installed at the top of the indoor air conditioner unit. The outdoor air conditioner unit comprises a condenser, a condenser fan and a condenser self-cleaning device. The condenser is connected with the multipliers and is connected with the evaporator through a pipeline. The condenser fan is arranged on the upper portion of the condenser and discharges air upwards. The condenser self-cleaning device is arranged in the outdoor air conditioner unit. Through the dual system air conditioner, dual-working-condition operation can be achieved, thermal environment in a railway passenger station building equipment room is controlled independently, reliability and safety of operation of an air conditioner system are ensured, and the energy utilization rate is also increased.

Description

technical field [0001] The invention belongs to the field of ventilation and air conditioning for railway machine rooms, and more specifically relates to a dual-system air conditioner for railway machine rooms. Background technique [0002] At present, the safe operation of the air conditioner in the railway machine room is very important. If there are frequent failures, it will bring safety hazards to the traffic communication equipment in the machine room, and then endanger the traffic safety. In addition, there are a large number of equipment rooms in the railway centralized information room, such as information system room, network equipment room, communication room, etc., which are generally located in the inner area of ​​the building. Index 400~2000W / m 2 ), more than 95% of which is sensible heat, which needs to be cooled even in winter. In order to ensure a stable working environment for electronic equipment, it is required that the air conditioner serving the compu...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the above defects or improvement needs of the prior art, the present invention provides a dual-system air conditioner for a railway machine room, in which a dual-system air conditioner suitable for a railway machine room is designed in combination with the characteristics of the railway machine room itself, and the air conditioner can realize duplex The thermal environment in the equipment room of the railway passenger station building is controlled independently, which not only ensures the reliability and safety of the air conditioning system, but also improves the energy utilization rate, and solves the problem that the air conditioner in the equipment room occupies a large area and the system is complicated. , poor reliability and other problems, it can be widely used in equipment rooms of railway passenger station buildings
