Computer room air conditioning system and corresponding control method

Abstract

The present invention provides a machine room air conditioning system and a corresponding control method, wherein the machine room air conditioning system includes an air conditioning room, the air conditioning room has an evaporator and a fan matched with the evaporator, and the air conditioning room has a fresh air inlet, cold air An outlet and a return air outlet, the fan can drive the airflow in the return air outlet and / or the fresh air inlet to flow through the evaporator and transport it into the machine room through the cold air outlet. According to the present invention, the fan in the air-conditioning room can drive the air in the machine room and / or the air in the air-conditioning room to the evaporator for cooling and cooling, so that the enthalpy of the outdoor air of the air-conditioning system is lower than the enthalpy of the indoor air. When the enthalpy value of the outdoor air is relatively low, it can be introduced into the equipment room to cool and dissipate heat, especially when the enthalpy value of the outdoor air is relatively low, the corresponding air conditioning system can be controlled to only run the fan to introduce the outdoor air into the equipment room, reducing the The power consumption of the air-conditioning system is more energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a computer room air conditioning system and a corresponding control method. Background technique [0002] The rapid development of the information industry and digital construction has promoted the number of computer rooms and base stations, and the construction scale has grown rapidly. According to statistics, the energy consumption of air conditioners in computer rooms and base stations accounts for more than 40% of their total energy consumption. The sensible heat load of computer rooms and base stations is large, and continuous operation is required throughout the year, making the current situation of energy shortage increasingly serious. The ordinary computer room air conditioning system consumes a lot of electricity, and the large power consumption will also have a certain impact on the environment. Therefore, it is necessary to improve the existing com...
