Description
Technical Field
The invention relates to a solution dehumidification system of a data room by using waste heat regeneration, belonging to the field of air conditioning of the data room.
Background
In recent years, with the continuous development of informatization, information-based equipment tends to be intensively managed, and more data rooms are gradually built. The heat dissipation system of the data computer room is an important guarantee for normal work of the computer room, and air cooling heat dissipation is still the main heat dissipation form of the data computer room. Therefore, the quality of the cold air required by heat dissipation of the data computer room is guaranteed to be very important.
At present, the main source of cold air of a data machine room is an air conditioner refrigerating system, and the cold air generated by an air conditioner contains a large amount of moisture. The data computer lab contains high density high accuracy electrical equipment, and the normal operating of data computer lab can seriously be influenced to steam in the air, and more serious person can cause IT equipment in the rack to meet water short circuit, and data computer lab catches fire and causes major fire incident. Therefore, the moisture in the cold air required by the heat dissipation of the data machine room is reduced, and the key for ensuring the normal operation of the machine room is realized. Meanwhile, the server in the machine room emits a large amount of waste heat, and the waste heat is not fully applied. The dehumidification aspect patent 201821452582.7 provides a single-row data center system with a rotary wheel dehumidification natural cold source, which solves the damp and hot problem in a data machine room through rotary wheel dehumidification, but the rotary wheel dehumidification system has large volume, large energy consumption, high manufacturing cost and insufficient installation space in the machine room, and removes moisture in a desiccant through a heater, thus not only saving energy, but also influencing the operation circuit of the machine room; patent 201520890456.X provides a data center air-cooled cooling system's waste heat recovery system in the aspect of the waste heat recovery, gets up the waste heat recovery that produces in the data computer lab through hot water reserve tank, though effectual resource of having utilized, hot water reserve tank is bulky, take up an area of extensively, and the air that lets in the data computer lab does not do the dehumidification simultaneously and handles, produces certain damage to the machinery of data computer lab.
The air conditioner cold air is used as an auxiliary system of a data machine room cooling system, on one hand, air conditioner cold air is introduced into the solution dehumidifier, moisture contained in the cold air is absorbed by the solution, and the dried cold air exchanges heat with the server to take away heat. On the other hand, the cold air which participates in heat dissipation flows into the solution regenerator after absorbing heat in the data machine room, the dehumidifying solution in the solution regenerator is heated to evaporate moisture contained in the dehumidifying solution, and the dehumidifying solution enters the solution dehumidifier after recovering the dehumidifying characteristic to continuously participate in the drying process of the air conditioning cold air. According to the invention, moisture in cold air of the air conditioner is removed by using the dehumidifying solution, so that normal operation of a data machine room is ensured; and the heat generated by the data computer room is utilized to promote the moisture in the dehumidifying solution after moisture absorption to evaporate, thereby ensuring the recycling of the dehumidifying solution.
