Ventilation channel structure of ceiling type indoor unit of air conditioner

Abstract

The invention discloses a ventilation channel structure of a ceiling type indoor unit of an air conditioner, which comprises a ventilation pipeline, an outside air influx, an air guide component, a pipeline connecting part and a ventilation main body, wherein the ventilation pipeline is arranged between an outdoor unit and the indoor unit and used for guiding outside air to the indoor unit; the outside air influx is used for guiding a part of the outside air guided to the indoor unit to the interior of the indoor unit; the air guide component is used for respectively guiding the outside air guided to the interior of the indoor unit and indoor air; the pipeline connecting part is used for guiding residual outside air to the interior of the indoor unit from the outside air guided to the indoor unit; and the ventilation main body is provided with a plurality of ventilation channels used for guiding the outside air guided by the air guide component and the pipeline connecting part to an indoor fan. The ventilation channel structure can maintain the air in an indoor space to be in a clean state and improve the product satisfaction of users.

Description

technical field [0001] The invention relates to an air-conditioning indoor unit, in particular to a ceiling-type air-conditioning indoor unit ventilation channel structure for ventilating indoor air by using the indoor unit with a ventilation assembly. Background technique [0002] Generally, an air conditioner sucks hot air in the room to exchange heat with a low-temperature refrigerant, then discharges the heat-exchanged air to the room, and repeats the above cycle to cool down the room, or reversely operates to heat the room. Heating system; it is a series of equipment consisting of compressor-condenser-expansion valve-evaporator. [0003] Air conditioners are divided into outdoor units (also called "outdoor side" or "radiation side") that are usually installed outdoors, and indoor units (also called "indoor side" or "heat absorption side") that are usually installed inside buildings. ). The outdoor unit is provided with a condenser (outdoor heat exchanger) and a compre...

AI Technical Summary

Problems solved by technology

[0013] However, the ceiling-mounted indoor unit of the prior art with the above structure has the following problems: the indoor unit sucks in the indoor air and performs heat exchange and discharges it, so it can only adjust the temperature of the indoor air, and it is difficult to maintain or improve the cleanliness of the indoor air

In addition, when the air conditioner is running, the indoor space is kept closed to improve the air conditioning efficiency, but there is a problem that the indoor air becomes more and more turbid

Not only that, when the indoor air is turbid, the windows are usually opened to ventilate the indoor air, and when ventilating in this way, the heat exchange efficiency will be reduced
