Description
Technical Field
The invention belongs to the technical field of machine room dehumidification, and particularly relates to a dehumidification method and a dehumidification system for a micro-module machine room.
Background
The machine room infrastructure micro-module product is a data machine room infrastructure product which is generated in recent years for adapting to rapid deployment and flexible capacity expansion of a data machine room. The micro-module is usually integrated with subsystem devices or components such as a server cabinet, an intelligent power distribution cabinet, uninterruptible power supply equipment, a row-level refrigeration precision air conditioner, a cold and hot channel sealing component, an intelligent micro-ring and the like, so that a group of micro-module products, namely a data machine room, are realized.
At present, in small and medium-sized micro-module products, air-cooled direct expansion inter-column precise air conditioners are mostly adopted as cold source equipment, and close to a server cabinet heat source, nearby cooling is achieved. The air-cooled direct expansion precise air conditioner adopts a compressor to refrigerate, and the complete system mainly comprises a compressor, a condenser, an evaporator and a throttling device. The refrigerant in the condenser installed outdoors is cooled directly by the outdoor air. The surface of the evaporator is low in temperature and lower than the condensation temperature of the air in the machine room during refrigeration, and water vapor in the air is condensed to form condensed water to be discharged, so that the environment can be dehumidified in a certain working condition range, and the temperature and humidity control of the environment in the machine room can be realized. And part of medium and large machine rooms adopt chilled water air conditioners as cooling equipment at the tail ends of the machine rooms, and the temperature of the machine rooms is controlled. The humidity control adopts a machine room constant humidity machine, and the constant humidity machine can dehumidify and humidify the machine room environment within a certain working condition range. The constant humidity machine is usually deployed in an air conditioner room of a machine room, and equipment installation needs to consider reserving a maintenance space and an air supply and return channel.
At present, the following problems exist in the control of the humidity of a machine room by an air-cooled direct expansion inter-row precise air conditioner:
(1) In the initial stage of the construction and operation of the medium and small-sized data machine room, the number of servers put on shelves is often small, and the number of servers put on shelves gradually increases along with the customer service planning. The corresponding server loading rate is relatively low (below 10%) within one year before the construction operation, and the air conditioner of the air-cooled direct expansion room cannot realize stable dehumidification under low load.
(2) Air-cooled direct expansion air conditioner is limited by the working principle, and the compressor must be started to dehumidify. The precondition for the compressor to be turned on depends on the room temperature, and the heat generated by the operation of the room server is the basis for the stable operation of the compressor. When the load of a machine room is low, the generated heat is less, the refrigerating capacity of the air conditioner is seriously not matched with the load, and the air conditioner stops running after being started to run for a few minutes because the temperature of a sensor acquisition area reaches a set point, so that the compressor is frequently started and stopped. The internal logic of the air conditioner is usually to ensure that the temperature priority is higher than the humidity priority, the air conditioner reaches a refrigeration point, and the compressor stops running. Even if the current humidity is higher, the unit can stop refrigerating to prevent the temperature of the machine room from being too low, so that the air conditioner cannot effectively dehumidify.
(3) From the principle of the enthalpy and humidity of air, the lower the temperature of the dry bulb is, the higher the relative humidity of the dry bulb is under the condition of the same air moisture content. The machine room design specification GB50174 requires that the relative humidity of air in an air inlet area of a server of the machine room is not more than 60%, and an air-cooled direct expansion room air conditioner is adopted for dehumidification, so that the dehumidification mode is more required to further reduce the temperature of an evaporator, the temperature of an air supply area of the server is further reduced by lower air supply temperature, the relative humidity in the area is not reduced and reversely increased due to low temperature, the appearance that the higher the relative humidity is dehumidified, a high humidity alarm is triggered, and the requirement of the operation of the server on the relative humidity cannot be met.
At present, the following problems exist in humidity control through a machine room dehumidifier:
(1) Only the dehumidifying air circulation can be carried out on the air in the installation environment of the constant humidity machine, namely the hot channel. The temperature of the hot passage area is high, the relative humidity is low, and the situation that the temperature of the cold area is low and the relative humidity is over 60% may occur when the area where the constant humidity machine is located does not reach the machine set start-up humidity condition.
(2) When the machine room constant humidity machine is initially selected, the machine room constant humidity machine is designed according to the most unfavorable humidity dehumidification working condition of the machine room environment, and the most unfavorable environment working condition of the machine room is only in one to two months with relatively high outdoor environment relative humidity in one year, and most of the time is in an intermittent operation or shutdown state. After the installation is completed, the device cannot be flexibly disassembled, assembled, expanded and reduced in volume along with seasons or use conditions.
In summary, in the present situation, no matter what dehumidification scheme is adopted, there are certain limitations and disadvantages.
