Indoor unit of fresh-air air conditioner

Abstract

The invention provides an indoor unit of a fresh-air air conditioner. The indoor unit comprises a shell and a fresh-air device, wherein the fresh-air device is arranged on the end part of one side ofthe shell, and comprises an air inlet module and a fan module communicated with the air inlet module; an air inlet cavity is limited in the air inlet module, and an air inlet port is formed in the rear lower part of the air inlet module, and used for introducing outdoor gas into the air inlet cavity; and the fan module conveys the outdoor fresh air introduced by the air inlet module into a room, apurification module is arranged at the inner side of the air outlet port of the fan module, and a secondary heat exchanger is arranged on the lower part of the purification module. According to the indoor unit provided by the invention, the secondary heat exchanger is arranged on the fan module of the fresh-air device, after a fresh-air function runs, the amount of air needing to be subjected toheat exchange, of the air conditioner, during refrigeration / heating, is increased, and a longer time is needed for reaching a set temperature; and the secondary heat exchanger is installed in the fresh-air device, and refrigeration / heating is carried out on the fresh air entering the room in advance, so that the heat exchange effect of the air conditioner can be effectively improved, and the comfort of the user during use is improved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a fresh air air conditioner indoor unit. Background technique [0002] An air conditioner is a widely used household appliance. It generally has heating and cooling functions. When the ambient temperature is too low or too high, it can adjust the temperature of the indoor air to provide users with a suitable indoor environment and effectively improve the air conditioner. Quality of life of users. [0003] However, because the current air conditioners only circulate the indoor air to heat or cool down when heating or cooling, and the user will close the door of the living room at the same time in order to maintain the indoor temperature, so that the indoor air quality will be reduced. It will gradually deteriorate, which will adversely affect the user's health. In particular, in recent years, air pollution has been increasing day by day, especially in the winter heating season, and people a...

Problems solved by technology

[0004] After the fresh air device is introduced into the current air conditioner indoor unit, when the fresh air function is used, the amount of air for heat exchange will increase. Under the premise that the cooling / heating capacity of the air conditioner remains unchanged, it will take longer for the air conditioner to reach the user's setting when it is running. The temperature will make the cooling / heating effect worse, thus affecting the user experience
