VRV air-conditioning system suitable for equipment machine room

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...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the terminal indoor units in each computer room do not have separate humidification and heating functions, so that the temperature and humidity of the indoor units cannot be adjusted accurately, resulting in the temperature and humidity in the computer room being too low and affecting the equipment in the computer room performance can even lead to equipment failure
