Air conditioner indoor machine and air conditioner

Abstract

The invention provides an air conditioner indoor machine and an air conditioner. The air conditioner indoor machine comprises a housing, a heat exchanger and an air fan, wherein an air outlet window is formed in the housing, the heat exchanger comprises a plurality of fins, and the distribution density of the fins adjacent to an air outlet of the air fan is larger than the distribution density ofthe other fins far away from the air outlet of the air fan. Fin pitch between each two adjacent fins adjacent to the air outlet of the air fan is set in small dimension, and fin pitch between each twoadjacent fins far away from the air outlet of the air fan is set in large dimension, and then air flow resistance in the air outlet of the air fan can be increased through the fins, and therefore a large amount of air can be blown out from spaces among the fins far away from the air fan so as to reduce air speed of a part, close to the air outlet of the air fan, of the air outlet window, and raise air speed of the other part, far away from the air outlet of the air fan, of the air outlet window, and then the air speed of all positions on the air outlet window is uniform, the heat exchanger isenabled to achieve uniform heat exchange effects on all positions on the heat exchanger, and when the air volume of the air conditioner indoor machine is equal to that of an existing air conditionerindoor machine, heat exchange amount is large, the highest air speed value is reduced, and then running noise can be reduced.

Description

technical field [0001] The invention belongs to the field of air conditioners, and more specifically relates to an air conditioner indoor unit and an air conditioner. Background technique [0002] Fins are generally provided on the heat exchanger in the indoor unit of the air conditioner to improve heat exchange efficiency. The fins of current heat exchangers are usually arranged at equal intervals. One or more fans are generally arranged in the indoor unit of the air conditioner, and when the fans rotate, air is blown out through the fins to exchange heat. Since the wind speed blown by the fan is not uniform along the axial direction of the fan, coupled with the resistance of the fins, the unevenness of the wind speed is particularly obvious along the length direction of the heat exchanger. The closer to the fan outlet, the greater the wind speed. When two or more fans are operating simultaneously, the wind speed distribution is more complicated. Due to the uneven distr...

Problems solved by technology

[0003] The purpose of the present invention is to provide an air-conditioning indoor unit to solve the problems in the prior art that the wind speed distribution in various parts of the air-conditioning indoor unit is uneven, which affects the heat exchange effect and makes the operation noise larger
