A wall-mounted air conditioner fresh air device

Abstract

The invention discloses a wall mounted air conditioner fresh air device which comprises an air guide connector, a first flexible pipe, a pipe joint connector, a second flexible pipe, a self control box and a fresh air sucking pipe. The device is provided aiming at an air conditioner under the opening-closing control, fresh air can be provided indoors during the air supplying work of the air conditioner under the refrigerating work condition in summer, and indoor and outdoor air of a fresh air pipe can be separated automatically and effectively in the air conditioner stopping intermittence to prevent waste. Under the heating work condition in winter, the device can provide fresh air continuously, and the intensity of the fresh air can be adjusted. The device adopts pure mechanical structure and mechanical control, does not require any power device, is safe and reliable, can be directly installed and used on a wall mounted air conditioner without modifying the structure of the existing wall mounted air conditioner and a wall body. The fresh air device is especially practical for small rooms under opening-closing control, such as studies and small bedrooms.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and air conditioning, and in particular relates to a wall-mounted fresh air device for air conditioning. Background technique [0002] Wall-mounted air conditioners are widely used in our country. Its main components are indoor unit, outdoor unit and refrigerant pipe connecting them. In the process of cooling or heating, the indoor air is circulated. When the air conditioner is turned on, in order to save electricity, people usually close the doors and windows, so that the gaseous chemicals released by the interior decoration materials cannot be diluted or eliminated, which leads to the occurrence of air conditioner diseases. For this reason, some people have to frequently open the window for ventilation, which not only has poor comfort, but also does not save energy. [0003] The current fresh air system uses a full heat exchanger to exchange heat between the outdoor fresh air and the in...

Problems solved by technology

In the prior art, researchers have introduced outdoor fresh air into the air supply suction end of the indoor air conditioner by adding a fresh air pipe. This method can increase the indoor fresh air supply, but there are the following defects: First, most of the current The air conditioners are controlled on and off. The air conditioners can inhale fresh outdoor air when there is wind, but when the studio is stopped, because the indoor and outdoor air in the fresh air pipe is connected, it will cause indoor cold / heat waste; secondly, the current technology adds fresh air The pipeline needs to open holes in the wall, which makes the installation cost and modification amount larger
