Description

Technical Field

[0002] Air conditioning, or air conditioner, refers to a device that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure.

[0003] The air conditioner indoor unit includes a shell, a heat exchange fan and a heat exchanger. The heat exchange fan and the heat exchanger are arranged in the shell. The shell is provided with an indoor air inlet and an indoor air outlet. Usually, a longitudinal air guide plate is provided at the indoor air outlet. The longitudinal air guide plate can guide the wind flowing out of the indoor air outlet to change the air outlet direction of the indoor air outlet, so that the user can adjust the air outlet direction of the indoor air outlet according to needs.

[0004] At present, since the indoor air outlet is relatively wide, the longitudinal blades need to cover the entire indoor air outlet. The longitudinal blades are usually installed by matching the shaft holes at the upper and lower ends through the deformation of the longitudinal blades. The installation by the overall deformation of the longitudinal blades is more difficult. The overall deformation of the blades can easily lead to irreversible deformation, affecting the rotation of the blades. The contact surface of the shaft holes at the upper and lower ends is large, which increases the friction resistance and reduces the movement reliability of the longitudinal blades.

The expansion valve expands the liquid phase refrigerant at high temperature and high pressure condensed in the condenser into a low pressure liquid phase refrigerant.

[0069] The indoor heat exchanger evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low temperature and low pressure state to the compressor. The indoor heat exchanger can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.
