Meanwhile, aiming at the newly-released air conditioner which is not different in installation direction (forward direction and reverse direction), the evaporator is reserved with installation joints in the corresponding direction for processing, and the convenience of air conditioner installation is guaranteed. When air is sucked into the cavity from the upper air inlet by the fan blades and then blown out from the lower air inlet after exchanging heat with the evaporator part shown in the figure 1, the air suction of the upper cross-flow fan blade 40 is matched with the air blowing of the lower cross-flow fan blade 50, the negative pressure at the air suction inlet can effectively improve the pressure difference at the air outlet, and the high pressure difference further improves the air quantity flowing through the whole cavity, thereby being more beneficial to improving the heat exchange efficiency of the evaporator and ensuring the strong refrigerating and heating effects of the air conditioner.
The direction of the shell is defined as positive when any air outlet is used as the lower air outlet, the shell needs to be connected in the forward installation mode, the lower end control valve is opened through a tool, the two valves (the pipe inlet valve body and the pipe outlet valve body) are opened and screwed to the maximum, at the moment, the indoor unit and the outdoor unit are communicated through the connecting pipe, and the refrigerant of the indoor unit and the refrigerant of the outdoor unit form circulation after the indoor unit and the outdoor unit are started up are. When the air conditioner is reversely installed, the two control valves at the upper end are closed tightly (based on the installed position relation), the two control valves at the lower end are opened, the connecting pipe is connected with the indoor unit through the two control valves at the lower end, and a new cycle is formed again after the air conditioner is started.
In order to ensure that the positive and negative directions of the air conditioner with upper and lower air outlets can obtain consistent high refrigeration/heating quantity, the air conditioner comprises a panel 13, upper and lower through-flow fan blades, a bottom shell 14, upper and lower air ducts and most of an evaporator. When the air conditioner operates, the lower air outlet duct is subjected to special diffusion treatment, namely a pre-installed diffusion structure is additionally arranged, so that air outlet of the air conditioner from the lower end is ensured. The upper air duct sucks air, and air enters the cavity and is blown out from the lower air outlet duct through the evaporator. Wherein, the evaporator is positioned in the middle part of the upper and lower cross-flow fan blades. The diffusion angles of the upper air outlet duct and the lower air outlet duct need to be adjusted according to actually measured air volume data. The 4 control valves of the evaporator require tools to be unscrewed.
With the appearance and popularization of the air conditioner with upper and lower air outlets, how to design the evaporator can ensure that the air conditioner is not influenced by installation becomes a research subject. Fig. 1 is a side sectional view of an indoor unit, and generally, when fig. 1 is taken as a default installation direction, a special diffuser angle treatment is not performed at an upper air inlet, but air inlet is increased as much as possible. The lower air inlet is subjected to special diffusion angle treatment to ensure air outlet, the air is blown out from the lower air outlet, the inlet air enters the cavity of the whole machine from the upper air duct through the upper cross-flow fan blade, passes through the evaporator in the cavity and is blown out from the lower air duct through the lower cross-flow fan blade. The connecting pipe of the indoor unit and the outdoor unit is connected through the lower end flow control valve, and the upper end flow control valve is locked at the moment, so that the refrigerant is prevented from leaking from the upper end. The valve cap is synchronously connected, the control valve at the lower part is opened, and the refrigerant circulates between the indoor machine and the outdoor machine through the control valve.
Further, if the user is at the beginning of installation, and the user is inclined to install the angle opposite to that of fig. 2, the original lower end control valve becomes the upper end control valve, and the control valve on the upper portion is locked at this moment, in order to further prevent the refrigerant from leaking, a threaded bonnet is connected to the control valve, and further, the refrigerant is prevented from leaking. And the control valve at the lower part is fully opened, and at the moment, the outdoor unit of the indoor unit is connected through the control valve at the lower part. The control valve may be implemented by an electronic expansion valve system.
