Abstract

The invention provides a fresh air window air conditioner which comprises a box body, an emergency air duct, an emergency fan and a control device, wherein an indoor cavity and an outdoor cavity are defined by the box body, and the box body part of the indoor cavity is provided with an emergency air opening communicated with the indoor environment; the emergency air duct communicates with the indoor cavity and the outdoor cavity; the emergency fan is arranged at the emergency air opening and is configured to suck indoor air from the emergency air opening and promote the sucked indoor air to form airflow flowing to the outdoor cavity through the emergency air duct; and the control device is configured to open the emergency air opening and start the emergency fan when it is determined that a refrigerant leakage event occurs, so that the emergency fan sucks the indoor air from the emergency air opening, and the sucked indoor air carries leaked refrigerant and then flows to the outdoor cavity through the emergency air duct. Based on the scheme provided by the invention, the leaked refrigerant can be prevented from flowing into a room as much as possible especially aiming at the condition that the R290 refrigerant is adopted by the air conditioner.

Description

technical field [0001] The invention relates to the design field of daily household appliances, in particular to a fresh window air conditioner. Background technique [0002] The refrigerants used in existing air-conditioning systems are usually R22 and R410, which are poor in environmental protection and will destroy the ozone layer. Most environmentally friendly refrigerants are flammable, such as R290 (propane), which has zero ozone depletion potential, is very friendly to the environment, and is relatively easy to obtain and economical. However, because flammable refrigerants are harmful to the human body, safety must be considered before using flammable refrigerants. [0003] The traditional household air conditioner split unit includes an outdoor unit installed outdoors and an indoor unit installed indoors. The refrigerant circulates between the indoor unit and the outdoor unit through pipes to achieve heat exchange. In this mode, once the refrigerant leaks from the ...
