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 shops and some 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 streams into each room through an arrangement of air ducts. The air duct is provided with an air port in the room to supply air to the room. The existing ventilating duct air opening is generally provided with a shutter structure, and the shutter structure can better guide air flow to enter a room from the ventilating duct and can also prevent small animals from entering the ventilating duct. However, the existing shutter structure is usually a fixed structure.
In part of the prior art, the phase change material is arranged in the air duct opening shutter structure, so that the energy storage property of the phase change material is facilitated, and the effect of heat storage (cold) heat release (cold) is achieved so as to achieve the further regulation and control effect on the end load of the temperature control system. For example, CN201710146827.7 discloses an energy-saving shutter, which comprises a shutter, wherein a shell is fixed at the upper part of the shutter, the interior of the shell is divided into a first cavity and a second cavity by a partition plate, an air supply port is arranged on the side wall of the second cavity, an air return port is arranged on the bottom surface of the first cavity, wherein the air return port is positioned above a shutter curtain of the shutter, and the air supply port 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 one end of the air channel, which is close to the second cavity, is provided with a guide plate, and the guide plate points to the blades of the wind wheel.
According to the prior art, the phase change material is arranged in the shutter structure, when the cooling temperature of the ventilation system in summer is lower, the condensation and liquefaction of the phase change material can be used for absorbing part of cold energy storage, and discomfort caused by overlooking of low cold air flow by a human body in a house is avoided. When the temperature is too high, the phase change material can be relied on for vaporization and heat absorption and storing part of heat, so that discomfort caused by the fact that a human body in a house negligibly encounters too high hot air flow is avoided. The function of automatic regulation and control of the temperature of the tail end load of the air conditioning system is achieved. However, this structure has a disadvantage that if the indoor personnel have a reduced supply air temperature requirement during the cooling in summer, it is generally indicated that the indoor personnel want to obtain a lower indoor temperature environment as soon as possible, and the cooling requirement is high. Therefore, when the temperature of the phase change material arranged in the shutter structure suddenly drops, part of cold energy can be absorbed to avoid discomfort of human body, but the action itself also causes the reduction of the cold energy sent into the room, which is substantially equivalent to the reduction of the refrigerating effect of the air outlet, which is contrary to the actual requirement of users. The same contradictory problems exist in winter heating. Therefore, the humanized control of the air conditioning system is not facilitated to be improved.

By regulating and controlling the temperature and increasing the air output, the comfort level of air supply is ensured, the high-speed effect of temperature regulation in the house is ensured, and the humanized control effect is improved.
Further, a path for the phase change material to flow is arranged in the phase change material storage space, and the gravity center position of the shutter structure is changed by the flow of the phase change material in the phase change material phase change process, so that the automatic adjustment of the gradient of the shutters in the shutter structure is realized.
