Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific examples, which should not be construed as limiting the invention.
Referring to fig. 1 to 4, according to an embodiment of the present invention, an air conditioner terminal is provided, the air conditioner terminal includes a casing 10 and a radiation plate 20, a mixed flow air duct 11 is provided inside the casing 10, an air supply opening 12 and an air return opening 13 are provided on the casing 10, and the air return opening 13 is communicated with the air supply opening 12 through the mixed flow air duct 11; and a radiation plate 20 connected to the housing 10 and located at the return air inlet 13.
Indoor air enters the mixed flow air channel inside the shell after passing through the radiation plate for heat exchange, and is blown into the room through the air supply outlet after being fully mixed in the mixed flow air channel, so that heat exchange is carried out indoors. The utility model discloses a terminal structure of air conditioner improves the heat exchange efficiency of air through the form that adopts radiation and convection current, and the energy consumption is lower, and is more energy-concerving and environment-protective.
Preferably, the radiation plate 20 protrudes from the air return opening 13, and the radiation plate 20 is at least partially located outside the housing 10. The radiation plate arranged at the air return opening is exposed to increase the radiation area. Assuming that the length of the return air inlet is 80mm and the width is 100mm, the radiation heat exchange area is 8000mm 2 The diameter of refrigerant pipe on the radiant panel is 7mm, the number is 10, the circumference is about 11mm, after being exposed, the diameter is increased by (5.5-3.5) × 10=20mm 2 That is, the total area of the radiation heat exchange is 8020mm 2 The heat exchange area growth rate of one air return inlet is 0.25%, and if the number of the same air return inlets in the room is 4 at the moment, the total heat exchange area is increased by 1%.
The radiation plate 20 is detachably coupled to the housing 10. The user can design and install the radiation plate according to the maximum load of the room to increase or reduce the area of the radiation area. When the heat load of the room is maximum, the cooling demand can be met by adjusting the area utilization rate of the radiant panel to 100%. In the operation process, the area of the radiation plate is adjusted according to the room load, when the indoor load is increased, the area of the radiation heat exchange plate is increased, the radiation heat exchange is enhanced, and the indoor heat load requirement is met; when the indoor load is reduced, the area of the radiation heat exchange plate is reduced, the radiation heat exchange is reduced, the indoor heat load requirement is met, and the space pertinence and adjustable control are realized.

The gradually reducing structure of the first air duct section 11a can condense moisture in the air entering the mixed flow air duct on the side wall of the first air duct section, namely, water molecules collide the side wall of the gradually reducing structure to condense, and then stay in the mixed flow air duct, so that the moisture content of the air blown out of the air supply outlet is reduced. Meanwhile, the air conditioning unit is additionally provided with temperature detection equipment for detecting the temperature: t = A phi + Bt, (phi is relative humidity, t is dry-bulb temperature, namely air temperature), when the temperature detection equipment detects that the air temperature is greater than the dew point temperature, the air blows out through the air supply outlet at the moment, condensation phenomenon will not occur, the human comfort of the human body is greatly increased, and the air conditioning experience is improved.
In order not to affect the air volume of the outlet air, the second air duct section 11b is further modified in this embodiment, and in this embodiment, the diameter of the second air duct section 11b gradually increases from the first end to the second end of the second air duct section 11 b.
Preferably, a fan 30 for driving the airflow to flow is disposed in the mixed flow duct 11, and in this embodiment, the fan 30 is a cross-flow fan. Referring to fig. 3 and 4, the cross flow fan of the present embodiment is two in number and driven by one motor, and the two cross flow fans are coaxial.
