Heat recovery type VRV air-conditioning system suitable for subway station room

Abstract

The invention relates to a heat recovery type VRV air conditioning system suitable for a subway station room. The heat recovery type VRV air-conditioning system comprises a control system, a VRV air-conditioning refrigeration system, a heating system, a ventilation system and a pipeline system, and the pipeline system is controlled by the control system to communicate the VRV air-conditioning refrigeration system, the heating system and the ventilation system for heat exchange. The adjusting capacity of the subway air conditioning system is improved, the energy consumption of the system is reduced, the comprehensive energy efficiency of the system is improved, and the operation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of subway station air-conditioning systems, in particular to a heat recovery VRV air-conditioning system suitable for subway station rooms. Background technique [0002] At present, as a fast and convenient means of transportation, the subway has been actively used in large and medium-sized cities in my country, such as Beijing, Shanghai, Tianjin, Guangzhou, Shenzhen, Wuhan, Chengdu, Ningbo, etc., which to a certain extent has contributed to the rapid development of cities Alleviate the problem of traffic congestion. However, the space of the subway station is relatively closed, and the daily operation and management of the subway station need to consume a lot of energy, and the operation of equipment (such as communication equipment, electrical power equipment, etc.) will also generate a lot of heat. It is the key to study the energy-saving technology of the subway system while reducing the energy consumpti...

Problems solved by technology

However, the space of the subway station is relatively closed, and the daily operation and management of the subway station need to consume a lot of energy, and the operation of equipment (such as communication equipment, electrical power equipment, etc.) will also generate a lot of heat. It is the key to study the energy-saving technology of the subway system while reducing the energy consumption of the subway system and reducing the operating cost while cooling and supplementing the heat.

[0003] Most of the existing subway station equipment and management room air-conditioning systems are conventional air-conditioning systems, which use screw-type chillers as cold source central air-conditioning, which has poor adjustment ability, low overall energy efficiency of the system, and difficulty in setting up outdoor units; in addition, conventional air-conditioning The system generally cannot heat in winter, and a separate heating system is needed to heat the management room, which increases the complexity of the system and operating costs
