Description
Technical Field
The invention relates to the technical field of building temperature control ventilation, in particular to a method for controlling air outlet of an air duct.
Background
In large buildings such as hotels, office buildings or shopping malls and high-grade residential houses, a central air conditioning ventilation system is usually arranged to control ventilation and temperature in the houses. Central air conditioning ventilation systems typically employ centrally located cooling and heating units to deliver air to the rooms via an air duct arrangement. The air duct is provided with an air port in the room to supply air to the room. The air opening of the existing air duct is usually provided with a louver structure, the louver structure can better guide air flow to enter a room from the air duct, and small animals can be prevented from entering the air duct. However, the existing shutter structure is usually a fixedly arranged structure.
In part of the prior art, the phase-change material is arranged in the air duct opening shutter structure, the energy storage property of the phase-change material is facilitated, and the effect of heat storage (cold) and heat release (cold) is achieved so as to achieve the further regulation and control effect on the terminal load of the temperature control system. For example, CN201710146827.7 discloses such an energy-saving louver, which includes a louver, wherein a casing is fixed on the upper portion of the louver, the inside of the casing is divided into a first cavity and a second cavity by a partition plate, a supply-air outlet is formed in the side wall of the second cavity, and a return-air inlet is formed in the bottom surface of the first cavity, wherein the return-air inlet is located above the louver of the louver, and the supply-air outlet faces indoors; an air duct penetrating through the partition plate is arranged on the partition plate, a fan is arranged in the first cavity, and an air outlet of the fan is communicated with the air duct; a wind wheel is arranged in the second cavity, heat conduction pipes are distributed on the wind wheel, and solid phase change materials are arranged in the heat conduction pipes; and a guide plate is arranged at one end of the air channel close to the second cavity and points to the blades of the wind wheel.
Above-mentioned this kind of prior art sets up phase change material in tripe structure, when the ventilation system cooling in summer, when the cooling temperature is lower, can absorb partial cold volume storage by phase change material's condensation liquefaction, avoids human meeting the cold air stream that hangs down suddenly in the room and produces the discomfort. In winter, when the temperature is too high, the phase-change material can be used for vaporization to absorb heat and store partial heat, so that discomfort caused by sudden high hot air flow in a human body in a house is avoided. The automatic regulation and control function of the load temperature at the tail end of the air conditioning system is achieved. However, this structure has a drawback that in summer, if the temperature requirement of the supplied air is lowered by the indoor personnel, it usually indicates that the indoor personnel want to obtain a lower indoor temperature environment as soon as possible, and the requirement for cooling is large. Therefore, when the temperature suddenly drops, the phase-change material arranged in the louver structure can absorb part of cold energy to avoid discomfort of human bodies, but the action of the phase-change material also reduces the cold energy sent into a room, which is substantially equal to the reduction of the refrigerating effect of the air outlet, and is contrary to the actual requirement of a user. The same contradictory problems also exist in winter heating. Therefore, it is not beneficial to improve the humanized control of the air conditioning system.

Of course, in other embodiments, the adjustment of the inclination of the louver in the louver structure can be realized by means of motor control or memory alloy control capable of generating automatic deformation according to the temperature. However, this requires new equipment or power, which increases the cost and is less stable.
