Solution: The end nozzle of the condensate drain pipe leading to the outdoor of the indoor unit of the air conditioner is made into a "U" shape, and the back edge of the U-shaped bend is lower than the front edge, which not only prevents the wind from flowing backwards, but also facilitates the discharge of condensate during the refrigeration operation of the air conditioner.
Precautions for installing air conditioner:
1. Prevent freon leakage when installing air conditioner. After the air conditioner is installed, the installer must check whether there is leakage at the air conditioner connection port to prevent freon leakage.
2. Prevent rainwater from flowing backwards into the room through the hole in the wall. During the installation of air conditioner, a slightly higher hole through the wall must be made indoors. After the installation is completed, the gap in the wall hole must be plugged with putty. If you use the drainage holes in the corridor, you should also pay attention to similar problems.
3. Prevent indoor water leakage. To ensure that the condensed water generated during air conditioning refrigeration can be discharged to the outside, you can pour a little water into the water tray of the air conditioner during installation to check whether it can be discharged to the outside.
4. Prevent outdoor water leakage. When air conditioning heats in winter, water drops will come out because of defrosting. Therefore, when installing the air conditioner, special attention should be paid to let the installer install the outlet nozzle and outlet pipe of the outdoor unit.
5. The outdoor unit of air conditioner can't be installed everywhere, so the location should be selected for future maintenance.
Extended data:
Air conditioning is air conditioning. It refers to the process of adjusting and controlling the temperature, humidity, cleanliness, speed and other parameters of the ambient air in the building/structure by manual means.
Generally, it includes cold source/heat source equipment, cold and hot medium transmission and distribution system, terminal device and other auxiliary equipment. It mainly includes water pump, fan and pipeline system. The terminal equipment is responsible for the specific treatment of air and temperature by using the cold heat from transmission and distribution, so that the air parameters of the target environment can meet the requirements.
