Embodiment 1

[0034] The above humidification module includes a humidifier 3 and a humidification spray head 4 , and the humidification spray head 4 is connected to the humidifier 3 .

[0035] The implementation principle of this embodiment is: the humidifier 3 is used to generate moisture, and then the moisture is humidified by the air volume provided by the indoor fan 2 through the humidifying nozzle 4 that is softly connected with the humidifier 3, so as to prevent the humidity from being blown by the equipment room. Low wind and humidity lead to excessive static electricity between devices and short-circuit faults.

Embodiment 2

[0037]The above-mentioned heating module includes an electric heater 5 .

[0038] The implementation principle of this embodiment is: use the electric heater 5 to heat the air volume provided by the above-mentioned indoor fan 2, which can avoid the low temperature of the equipment in the equipment room due to the low temperature of the air supply in the equipment room, thereby affecting the performance of the equipment. Further, the above-mentioned electric heater 5 is a PTC heater, which adopts a PTC ceramic heating element and an aluminum tube to form a U-shaped shape. The PTC heater has the advantages of small thermal resistance and high heat exchange efficiency, and the temperature rises rapidly, and when the fan fails Can self-control temperature, long service life.

Embodiment 3

[0040] The cycle refrigeration subsystem includes a variable frequency compressor 6, an oil-gas separator 7, a liquid-gas separator 8, and sensors connected through the pipeline system. The variable frequency compressor 6 is arranged between the oil-gas separator 7 and the liquid-gas separator 8.

[0041] The implementation principle of this embodiment is: the variable frequency compressor 6 can pressurize the circulating refrigerant in the pipeline system, and then separate the oil and water in the refrigerant through the oil-gas separator 7 and the liquid-gas separator 8 to improve The purity of the refrigerant makes the cooling efficiency higher. Furthermore, the variable frequency compressor 6 can adjust its own operating frequency according to the temperature collected by the temperature sensor to adjust the rotation speed of the compressor, control the flow rate of the refrigerant and the flow rate in the pipeline system, so that the terminal indoor unit can be quickly co...

Abstract

The invention relates to a VRV air-conditioning system suitable for an equipment machine room. The system comprises a circulating refrigeration subsystem, an outdoor VRV air-conditioning refrigerationsubsystem, at least one indoor VRV air-conditioning refrigeration subsystem and a pipeline system for communicating the circulating refrigeration subsystem, the outdoor VRV air-conditioning refrigeration subsystem and the at least one indoor VRV air-conditioning refrigeration subsystem. Each indoor VRV air-conditioning refrigeration subsystem comprises a humidification module and a heating module. The humidification module and the heating module are arranged in each indoor VRV air-conditioning refrigeration subsystem, and are cooperated with the circulating refrigeration subsystem and the outdoor VRV air-conditioning refrigeration subsystem which communicate through the pipeline system, so that each tail end indoor unit can control humidification and heating of the humidification modulesand the heating modules according to the temperature and humidity requirements of the tail end indoor unit, and the effects that the air supply temperature and humidity of operation of machine room equipment are flexibly and accurately adjusted, and energy waste caused by excessive humidification and heating is avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of subway station air-conditioning systems, in particular to a VRV air-conditioning system suitable for equipment rooms. Background technique [0002] At present, with the increasing demand for energy saving, emission reduction and green environmental protection in various fields, especially the high-efficiency and energy-saving data center computer rooms, subway station computer rooms, etc., the energy consumption and operating costs of data centers and subway station computer rooms are continuously and efficiently reduced has become a priority. For subway stations, the indoor units at the end of the traditional multi-split air-conditioning system do not have heating and humidification functions, and cannot accurately adjust the temperature and humidity of the equipment room of the subway station. [0003] For example, in the existing CN106871293A-the machine room heat pipe air conditioner adopting the VRV...
