This application relates to the technical field of air conditioning, and discloses an indoor unit of an air conditioner, including: a first switch, including first to third interfaces, and the second interface selectively communicates with the first interface or the third interface, wherein the first One interface is connected to the first refrigerant inlet and outlet of the indoor unit, the second interface is used to communicate with one end of the first online pipe, and the third interface is used to communicate with a vacuum device to evacuate the first online pipe. Fill the indoor unit with refrigerant through the first switch or other devices. After the indoor unit is filled with refrigerant, connect the second interface and the third interface, and vacuum the first online pipe through the vacuum device. On the one hand, it can Vacuumize the first online pipe on the indoor side to improve the safety of the vacuuming operation. On the other hand, there is no need to vacuum the indoor unit, and the time to evacuate the first online pipe is about 1 minute, which greatly shortens the air conditioning time. The vacuum time of the device. The application also discloses an air conditioner and an assembly method.
Description
technical field [0001] The present application relates to the technical field of air conditioners, for example, to an indoor unit of an air conditioner, an air conditioner and an assembly method. Background technique [0002] At present, air conditioners on the market, such as inverter air conditioners, must be vacuumed before installation. The vacuuming is carried out on the outdoor side and the vacuuming time is mostly more than 15 minutes, which makes the installation efficiency of the air conditioner low, the installation risk factor is high, and the installation cost is expensive, which brings a lot of inconvenience to the company and users. Contents of the invention [0003] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. The summary is not intended to be an extensive overview nor to identify key / important elements or to delineate the scope of these embodiments, but rather serves as a prelud...
