Embodiment 1

[0030] No wind cooling mode. When the indoor unit of the air conditioner is in cooling operation, when the radiation heat transfer and natural convection heat transfer can meet the indoor cooling load demand, the indoor unit of the air conditioner operates in the windless cooling mode, which is generally applicable to the state where the temperature difference between indoor and outdoor is not high or sleeping.

[0031] Such as figure 1 As shown, five radiation convection heat exchange tubes are arranged side by side, the tops of the five radiation convection heat exchange tubes are connected to the air outlet structure, the air outlet direction is side air outlet, and the bottoms of the five radiation convection heat exchange tubes are connected to the return air structure. In each radiative convection heat exchange tube, the top and bottom of the inner tube are respectively connected with the air outlet and return air structures, and the first refrigerant main pipe is arrang...

Embodiment 2

[0034] Breeze cooling mode. When the indoor unit of the air conditioner is in cooling operation, when the radiation heat transfer and natural convection heat transfer are not enough to meet the indoor cooling load demand, the indoor unit of the air conditioner operates in the breeze cooling mode.

[0035] The indoor fan is turned on to run in the breeze mode, and the design of the air outlet of the indoor unit and the organization of the air flow are assisted, so that the indoor personnel can hardly feel the influence of the air-conditioning wind. The low-temperature refrigerant enters the indoor unit from the first refrigerant main pipe, and flows out of the indoor unit from the second refrigerant main pipe. The indoor unit of the air conditioner performs radiation and natural convection heat exchange to the indoor environment through the outer wall of the radiation convection heat exchange tube group, and the insufficient heat transfer part performs forced convection heat ex...

Embodiment 3

[0038] Powerful cooling mode. When the indoor unit of the air conditioner is in cooling operation, when the room needs to be cooled quickly with a large load, the indoor unit of the air conditioner operates in the strong cooling mode.

[0039] The indoor fan is turned on to run at high wind speed, and the fan is installed in the return air box of the return air structure. The low-temperature refrigerant enters the indoor unit from the first refrigerant main pipe, and flows out of the indoor unit from the second refrigerant main pipe. On the one hand, the indoor unit of the air conditioner performs radiation and natural convection heat exchange to the indoor environment through the outer wall of the radiation convection heat exchange tube group, and on the other hand, performs forced convection heat exchange on the fan airflow through the inner tube of the radiation convection heat exchange tube group. The condensed water on the outer wall of the radiation convection heat exch...

Abstract

The invention relates to a breezeless or gentle breeze air conditioner indoor unit. The breezeless or gentle breeze air conditioner indoor unit is characterized in that the air conditioner indoor unit is formed by connecting a radiation convection current heat exchanging pipe piece, a refrigerant pipe piece, a return air structure and an air outlet structure; the radiation convection current heat exchanging pipe piece is composed of at least one radiation convection current heat exchanging pipe which is provided with an inner pipe and an outer sleeve, and the two ends of the inner pipe of each radiation convection current heat exchanging pipe are connected with the return air structure and the air outlet structure; and the refrigerant pipe piece comprises a refrigerant inlet pipe component and a refrigerant outlet pipe component which are arranged at the two ends of each radiation convection current heat exchanging pipe, and the refrigerant inlet pipe component and the refrigerant outlet pipe component communicate with a flow channel between the inner pipe and the outer sleeve of each radiation convection current heat exchanging pipe. The radiation convection current heat exchanging pipe piece is composed of one or more radiation convection current heat exchanging pipes, by means of ventilation and air outlet of the inner pipes, outer walls of the outer sleeves and the indoor air carry out cold and heat exchanging, breezeless or gentle breeze running can be achieved, the comfort level of the human body in a room is greatly improved, and the situations that as the air speed of the air conditioner indoor unit is too large, the human body feels uncomfortable and the immunity is lowered are avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit which can provide no wind or breeze function. Background technique [0002] Now, families have generally used air conditioners, bringing coolness and warmth to thousands of households. However, the current air-conditioning indoor units basically have a relatively high wind speed, which makes the human body feel a strong sense of wind, and is prone to catching cold and headaches. The main reason is that the current air-conditioning indoor units basically use the fan of the air-conditioning indoor unit to force the indoor air to pass through the heat exchange surface of the indoor unit to achieve heat exchange and to achieve forced convection of the indoor air. The advantage of this treatment method is that the heat exchange capacity is large, and the indoor cooling or heating speed is fast, but the disadvantage is that the wind speed is lar...
