[0002] Currently, the popular ground air conditioner indoor units on the market all have return air and supply air combined inside a single air outlet. The motor fan is installed in the return air position. Such equipment will cause insufficient static pressure at the air outlet and excessive negative pressure at the return air outlet, resulting in short-circuit of the inlet and outlet air, and seriously affecting the refrigeration capacity, making it unable to be used as a real air conditioner. Summary of the Invention:

[0003] The technical problem to be solved by the present invention is to provide a buried multi-functional air supply air conditioner indoor unit that meets the various needs of refrigeration, heating, and fresh air, reduces equipment investment, and decreases construction costs.

It is characterized in that: a surface cooler is arranged in the middle inside the body shell; a ventilation hole support plate is installed in front of and behind the surface cooler; an air cross-flow prevention partition is arranged in the middle of the surface cooler; a condensate water tray is installed below the surface cooler; one end of the condensate water tray is provided with a condensate water drain pipe; a wind collecting box is installed at the front end of the body shell, and the wind collecting box is connected to a centralized fresh air duct or a return air duct on the indoor ground; two groups of cross-flow fans are installed at the rear end of the body shell. When the wind collecting box is connected to the return air duct on the indoor ground, the two groups of cross-flow fans blow air in the same direction. Otherwise, one group of cross-flow fans blows air, and one group of cross-flow fans sends air to the surface cooler; the fresh air connector is fixed to the rear wall of the body shell, the small fan is installed inside the fresh air connector, the fresh air connector is connected to an air duct leading to the outside, and the air inlet and outlet are installed on the ground above the cross-flow fans.

[0007] The condensate water tray is installed below the surface cooler.

[0008] The condensate water drain pipe is fixed to one end of the condensate water tray.

[0009] The air cross-flow prevention partition is located in the middle of the surface cooler.

[0010] The air cross-flow prevention partition prevents the cross-flow of inlet and return air.

[0011] The air collecting box is at the front end of the fuselage shell.

[0012] The centralized fresh air duct is connected to the opening on the outer wall of the air collecting box.

[0013] Two sets of cross-flow fans are installed at the rear end inside the fuselage shell.

[0014] When the air collecting box is connected to the return air duct on the indoor ground, the two sets of cross-flow fans blow air in the same direction.

[0015] When the air collecting box is not connected to the return air duct, one set of cross-flow fans blows air, and one set of cross-flow fans sends air to the surface cooler.

[0016] The fresh air connector is fixed on the fuselage shell.

[0017] The fresh air small fan is installed inside the fresh air connector.

[0018] The fresh air connector is connected to the fresh air duct leading to the outside.

[0019] The air inlet and outlet are installed above the fuselage shell, and the cross-flow fans are below the air inlet and outlet.

[0020] The water inlet and return water port of the surface cooler are connected to outdoor equipment, or connected to a water tank or a water collector and then connected to outdoor equipment.

[0021] The small fan and the cross-flow fans are powered by a power supply.

[0022] The advantages of the present invention are as follows: The buried multi-functional air supply air conditioner indoor unit is connected to the centralized fresh air duct to become an integrated fresh air air conditioner. It is connected to the fresh air duct outside to achieve regional independent fresh air. In the buried multi-functional air supply air conditioner indoor unit, there is one set of cross-flow fans that send air towards the surface cooler, sending indoor air into the air collecting box. The air in the air collecting box returns to the other side and passes through the surface cooler and is sent out of the ground by the other set of cross-flow fans. When the air collecting box is connected to the underground return air duct, the two sets of cross-flow fans blow air in one direction, achieving the effect of multiple functions in one machine and flexible design.
