[0033] In related technologies, existing integrated air conditioning units have cooling and heating modes. In cooling mode, the refrigerant flows through the compressor, outdoor heat exchanger, and indoor heat exchanger; in heating mode, the refrigerant flows through the compressor, indoor heat exchanger, and outdoor heat exchanger. When in heating mode, the integrated air conditioning unit's heating efficiency is insufficient, affecting the user experience.

[0034] Reference Figure 1 , Figure 2 According to an embodiment of the present invention, an integrated air conditioning unit utilizing hot water for heating includes a housing assembly, an indoor heat exchanger 100, an outdoor heat exchanger 200, a compressor 300, a heater 400, and a water tank 500. The housing assembly has a first heat exchange chamber and a second heat exchange chamber that are separated from each other. The indoor heat exchanger 100 is disposed in the first heat exchange chamber, and the outdoor heat exchanger 200 is disposed in the second heat exchange chamber. The compressor 300 is disposed in the housing assembly and is connected in series with the indoor heat exchanger 100 and the outdoor heat exchanger 200 through pipes. The heater 400 has an inlet end and an outlet end. The heater 400 is located in the first heat exchange chamber. The water tank 500 is located in the shell assembly. The water tank 500 is connected to an inlet pipe 510 and a first outlet pipe 520. The end of the first outlet pipe 520 away from the water tank 500 is connected to the inlet end, and the end of the inlet pipe 510 away from the water tank 500 is connected to the outlet end. The first outlet pipe 520 passes through the indoor heat exchanger 100 to assist the indoor heat exchanger 100 in heating. In this way, the heating efficiency of the integrated air conditioning unit that uses hot water for heating can be improved.

[0035] For example, when an air conditioning unit that uses hot water for heating is in heating mode, the refrigerant flows from the compressor 300 to the indoor heat exchanger 100, and then flows back from the outdoor heat exchanger 200 to the compressor 300. At this time, the heater 400 is activated, and the water in the water tank 500 is heated by the heater 400 to form steam. The steam flows from the inlet pipe 510 through the indoor heat exchanger 100 back to the water tank 500. When the steam flows in the indoor heat exchanger 100, it can assist the indoor heat exchanger 100 in heating, thereby increasing the temperature of the indoor heat exchanger 100 and improving the heating efficiency of the air conditioning unit that uses hot water for heating.

[0036] In some embodiments of this utility model, the first water outlet pipe 520 is provided with a first pump body 530, which is used to pump water in the water tank 500 into the heater 400, so that the water in the water tank 500 can be easily extracted so that the heater 400 can generate steam.

[0037] It should be noted that the first pump body 530 can be a piston pump, a screw pump, or a centrifugal pump, etc., and there are no restrictions here.

[0038] It should be noted that heater 400 can be an electromagnetic heater, a resistance heater, or an infrared heater, etc., and there are no restrictions here.

[0039] In some embodiments of this utility model, the water tank 500 is provided with a liquid level detection component, which is electrically connected to the first pump body 530. The liquid level detection component is used to detect the liquid level height in the water tank 500 to prevent the first pump body 530 from running dry, thereby improving the automation level of the integrated air conditioning unit that uses hot water for heating.

[0040] For example, when the liquid level in the water tank 500 is lower than a preset value, the liquid level detection component sends a first electrical signal to the first pump body 530 to stop pumping water, thereby preventing the first pump body 530 from running dry. When the liquid level in the water tank 500 is higher than the preset value, the liquid level detection component sends a second electrical signal to the first pump body 530 to make the first pump body 530 draw water from the water tank 500, so that the heater 400 can generate steam.

[0041] It should be noted that the liquid level detection component can be a float-type liquid level sensor or a hydrostatic liquid level sensor, etc., and there are no restrictions here.

[0042] In some embodiments of this utility model, the water inlet pipe 510 includes a first connecting section 511, a second connecting section 512, and a bending section. The bending section is connected between the first connecting section 511 and the second connecting section 512. The bending section is located in the indoor heat exchanger 100. The first connecting section 511 is connected to the water outlet, and the second connecting section 512 is connected to the water tank 500. This can increase the contact area between the water inlet pipe 510 and the indoor heat exchanger 100, thereby accelerating the heating speed of the indoor heat exchanger 100 and improving the heating efficiency of the integrated air conditioning unit that uses hot water for heating.

[0043] For example, one end of the curved section is connected to the first connecting section 511, and the other end of the curved section is connected to the second connecting section 512. The curved section is arranged in an S-shape, which can increase the contact area between the water inlet pipe 510 and the indoor heat exchanger 100, thereby accelerating the heating speed of the indoor heat exchanger 100 and improving the heating efficiency of the integrated air conditioning unit that uses hot water for heating.

[0044] In some embodiments of this utility model, the first connecting section 511 and the second connecting section 512 are both located on the same side of the indoor heat exchanger 100. The pipeline layout is compact, which can reduce the overall volume of the integrated air conditioning unit that uses hot water for heating, thereby facilitating the packaging and transportation of the integrated air conditioning unit that uses hot water for heating.

[0045] In some embodiments of this utility model, a water spraying component and a water receiving component are also included. The water spraying component is located above the outdoor heat exchanger 200, and the water receiving component is located below the outdoor heat exchanger 200. The water tank 500 is connected to a second water outlet pipe 540. The water spraying component has a cavity and a water spraying hole that connects to the cavity. The water outlet end of the water spraying hole faces the outdoor heat exchanger 200. The end of the second water outlet pipe 540 away from the water tank 500 connects to the cavity. The water receiving component has a water receiving trough 710, which is used to collect water that has passed through the outdoor heat exchanger 200. This helps the outdoor heat exchanger 200 dissipate heat, thereby improving the cooling efficiency of the integrated air conditioning unit that uses hot water for heating.

[0046] For example, when the integrated air conditioner using hot water heating is in cooling mode, the refrigerant flows from the compressor 300 to the outdoor heat exchanger 200, and then flows back from the indoor heat exchanger 100 to the compressor 300. At this time, the temperature of the outdoor heat exchanger 200 is relatively high. The water in the water tank 500 can flow from the second outlet pipe 540 into the cavity, and then spray onto the outdoor heat exchanger 200 through the water spray hole. The water flowing through the outdoor heat exchanger 200 flows downward into the water receiving tank 710. Since the temperature of the water in the water tank 500 is relatively low, it can assist the outdoor heat exchanger 200 in dissipating heat, thereby improving the cooling efficiency of the integrated air conditioner using hot water heating.

[0047] It should be noted that there are multiple water spray holes, and the array of multiple water spray holes is spaced apart to ensure that the water spray is even and can dissipate heat evenly to the outdoor heat exchanger 200. This will not be elaborated further here.

[0048] In some embodiments of this utility model, a water pumping component is also included. The water pumping component includes a first driving member 810 and a water pumping impeller 820. The output shaft of the first driving member 810 is connected to the water pumping impeller 820. The water pumping impeller 820 is disposed in the water receiving tank 710 to pump up the water in the water receiving tank 710, which can improve the cooling efficiency of the integrated air conditioning unit that uses hot water for heating.

[0049] For example, when the integrated air conditioner that uses hot water for heating is in cooling mode, the first driving component 810 drives the water-pumping impeller 820 to rotate, so that the water-pumping impeller 820 can lift the water in the water tank 710. The water droplets lifted by the water-pumping impeller 820 can come into contact with the outdoor heat exchanger 200 to reduce the temperature of the outdoor heat exchanger 200 and improve the cooling efficiency of the integrated air conditioner that uses hot water for heating.

[0050] It should be noted that the water-pumping impeller 820 includes a connecting shaft and multiple blades. The connecting shaft is connected to the output shaft of the first drive member 810. The multiple blades are arranged at intervals along the circumference of the connecting shaft so that the water-pumping impeller 820 can lift the water in the water receiving tank 710. No limitation is made here.

[0051] In some embodiments of this utility model, the second water outlet pipe 540 is provided with a second pump body 550, which is used to pump water from the water tank 500 into the cavity, so as to facilitate the extraction of water from the water tank 500, so that the water spraying component can cool the outdoor heat exchanger 200, thereby improving the cooling efficiency of the integrated air conditioning unit that uses hot water for heating.

[0052] In some embodiments of this utility model, a first fan assembly 910 and a second fan assembly 920 are also included. The air outlet of the first fan assembly 910 faces the indoor heat exchanger 100, and the air outlet of the second fan assembly 920 faces the outdoor heat exchanger 200, which can improve the cooling efficiency and heating efficiency of the integrated air conditioning unit that uses hot water for heating.

[0053] In some embodiments of this utility model, the first fan assembly 910 includes a first volute, a first fan blade, and a second drive member. The first volute is provided with an air duct, the second drive member is disposed in the air duct, and the output shaft of the second drive member is connected to the first fan blade. The air blown out by the first fan blade passes through the indoor heat exchanger 100 and is discharged into the indoor space, which can improve the heat exchange speed between the air and the indoor heat exchanger 100, thereby improving the cooling efficiency and heating efficiency of the integrated air conditioning unit that uses hot water for heating.

[0054] The second fan assembly 920 includes a second volute, a second fan blade, and a third drive unit. The second volute is provided with an air duct, the third drive unit is located in the air duct, and the output shaft of the third drive unit is connected to the second fan blade. The air blown out by the second fan blade passes through the outdoor heat exchanger 200 and is discharged to the outdoor space, which can improve the heat exchange speed between the air and the outdoor heat exchanger 200, thereby improving the cooling and heating efficiency of the integrated air conditioning unit that uses hot water for heating.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
