Hanging type air conditioner indoor unit

Abstract

The invention relates to the technical field of air conditioners, in particular to a hanging type air conditioner indoor unit. The problem that in the prior art, an air purifier or large fresh air system is adopted to improve indoor air quality, and the effect is not ideal is solved. The hanging type air conditioner indoor unit comprises a shell, an air returning opening, an air outlet and a purifying module; the purifying module comprises a shell, an air inlet system and an exhaust system, the air inlet system comprises a dual-way air pipe, a first air inlet and outlet, a heat exchanger, an induced draft fan and an outdoor fresh air outlet pipe, the exhaust system comprises an indoor air inlet, an exhaust fan, a heat exchanger, a first air inlet and outlet and a dual-way air pipe; the purifying module can be mounted on one side of a shell of the hanging type air conditioner indoor unit. Through the arrangement manner that the purifying module can be mounted on one side of the shell ofthe hanging type air conditioner indoor unit, the hanging type air conditioner indoor unit can reasonably and effectively purify indoor air, and meanwhile, the oxygen content of indoor air can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a hanging air conditioner indoor unit. Background technique [0002] The air pollution report released by the International Energy Agency clearly mentioned that as many as 97% of Chinese people are exposed to the harm of PM2.5 that exceeds the World Health Organization standard. Serious air pollution has shortened the average life expectancy in China by 25 months. The cardiorespiratory immunity of the people in the heavy smog area has dropped by 10%... In recent years, due to the intensification of air pollution and the frequent occurrence of smog, people cannot often open the windows for ventilation, resulting in PM2 in the indoor air. 5 and other bacterial particles can easily invade the lungs and respiratory tract, causing cough, asthma, pneumonia and even lung cancer and other diseases, but also cause cross-infection between people, which is regarded as the root caus...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the poor purification effect of the technical solution of using a small air cleaner to improve the indoor air quality in the prior art, the transformation of the technical solution of using a large-scale fresh air system to improve the indoor air quality exists For the problem of high cost, the present invention provides a hanging air conditioner indoor unit, which includes a casing, an air return port, and an air outlet. The hanging air conditioner indoor unit also includes a purification module, and the purification module includes a housing, an air inlet system and The air exhaust system, the air intake system includes a two-way air duct arranged on the housing according to the direction of air flow, a first air inlet and outlet, a heat exchanger, an induced draft fan and an outdoor fresh air outlet pipe, and the first air inlet and outlet are set On the first side of the housing, the two-way air duct is installed on the first air inlet and outlet, and the air intake system is configured to allow outdoor fresh air to pass through the two-way air duct driven by the induced draft fan. After introducing the purification module and passing through the heat exchanger, it is introduced into the room or the air return port of the hanging air conditioner indoor unit through the outdoor fresh air outlet pipe; The indoor air inlet of the housing, the exhaust fan, the heat exchanger, the first air inlet and outlet, and the two-way air duct, the exhaust system is set to drive the indoor The air is introduced into the purification module through the indoor air inlet and passes through the heat exchanger to exchange heat with the fresh air introduced by the air intake system, and then is discharged to the outside through the two-way air duct; The second side is also provided with a second air inlet and outlet, and the second air inlet and outlet is equipped with a sealing cover; the purification module is installed on one side of the housing, and the two-way air duct communicates with the outdoor; or the purification module is set In the housing, the indoor air inlet is connected to the air return port, the outdoor fresh air outlet pipe is connected to the air outlet, and the two-way air pipe is connected to the outdoor
