A kind of direct ventilation machine room air conditioning system and its control method

Abstract

The invention discloses an air-conditioning system for a straight-ventilated machine room and a control method thereof. Static pressure sensor and control system, the computer room is provided with a fresh air inlet and an air exhaust port; the air supply system, exhaust system, refrigeration system, fresh air temperature and humidity sensor, return air temperature and humidity sensor, supply air temperature and humidity sensor and the computer room The indoor static pressure sensors are all connected with the control system. The invention adopts fresh air cooling in low-temperature seasons, and compressor refrigeration in high-temperature seasons; fully utilizes the total heat and cooling capacity of fresh air, uses natural cooling sources for a long period of time throughout the year, has good energy-saving effect, introduces less fresh air volume, and uses fresh air filter pretreatment The pressure is also relatively small; in the high temperature season, the return air does not need to pass through additional filter components, and directly enters the unit for cooling and humidification, and the power consumption of the blower components is small.

Description

technical field [0001] The invention relates to an air-conditioning unit, in particular to an air-conditioning system for a direct-ventilated machine room and a control method thereof. Background technique [0002] Traditionally used constant temperature and humidity precision air conditioners for computer rooms, including air-cooled cold air conditioners and water-cooled cold air precision air conditioners, are still the most widely used cooling methods for computer rooms; because the equipment in the computer room is constantly dissipating heat throughout the year, the compressor needs to be used all year round , the air conditioner consumes a lot of power; according to statistics, in this way, the energy consumption of the air conditioner accounts for 35% to 50% of the total energy consumption of the computer room, of which the energy consumption of the refrigeration system accounts for more than 70%, and the air supply system accounts for about 20%. The humidification sy...
