Indoor unit of cabinet air conditioner

Abstract

The invention relates to an indoor unit of a cabinet air conditioner, comprising a bottom disk, a shell, a front panel, an indoor heat exchanger, a centrifugal fan, a runner filter, a runner bracket, a motor, a water tank, a water divider and a regenerator, wherein the rotatable runner filter is arranged at a corresponding position at induced draft side of the centrifugal fan, particulate matter and impurities in air can be filtered by the runner filter, water is added to the runner filter by the water tank and the water divider, the rotating runner filter is heated by the regenerator arranged on one side of the runner bracket to evaporate the moisture of the runner filter, the steam generated in the heating process is mixed with the air collected by the centrifugal fan, and the increased steam-containing air affected by the centrifugal fan produces heat exchange with the indoor heat exchanger and is discharged indoors so as to increase stream contained in indoor air and indoor moisture and prevent persons from feeling uncomfortable due to dry indoor air.

Description

technical field [0001] The invention relates to the technical field of indoor units of air conditioners, in particular to a rotatable runner filter arranged at a corresponding position on the suction side of a centrifugal fan, and the water passing through the evaporating runner filter when the air conditioner is in heating operation Parts, so that the indoor unit of the cabinet air conditioner can increase the air humidity while completing the air filtration. Background technique [0002] Generally speaking, an air conditioner is a cooling / heating device that keeps the indoor temperature at the temperature required by the user. The refrigerant circulating in the refrigeration system exchanges heat with the air flowing in the room to achieve indoor cooling or heating. Provide fresh and comfortable air environment. The refrigeration system of an air conditioner is mainly composed of an indoor heat exchanger, an outdoor heat exchanger, a compressor, and a throttling expansion...

AI Technical Summary

Problems solved by technology

[0010] When the indoor unit of the cabinet-type air conditioner in the prior art performs heating operation in winter, the centrifugal fan sucks air from the room, the air flows through the indoor heat exchanger and is heated to form dry hot air, and the hot air is discharged from the air outlet to the The indoor temperature increases, resulting in the reduction of the water content in the form of water vapor in the air. When the total amount of water in the indoor air remains unchanged, the indoor relative humidity is inversely proportional to the temperature. The higher the temperature, the lower the relative humidity. , so people in the room will feel that the air becomes dry, causing physical discomfort
