Breezeless or gentle breeze air conditioner indoor unit

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...
