Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figs. 1-2 As shown, the high-efficiency split air conditioner of this embodiment includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit form a closed cooling and heating circuit.

[0026] The indoor unit comprises an indoor heat exchange structure 1, which comprises an indoor double-pipe heat exchanger 101 and an indoor water curtain heat exchanger 102, the indoor double-pipe heat exchanger 101 exchanges heat with the indoor water curtain heat exchanger 102, and the indoor water curtain heat exchanger 102 exchanges heat with indoor air.

[0027] The outdoor unit comprises an outdoor heat exchange structure 2, which comprises an outdoor fluorine medium heat exchanger 201 and an outdoor water curtain heat exchanger 202, the outdoor water curtain heat exchanger 202 covers the water film in it on the refrigerant copper pipe of the outdoor fluorine medium heat exchanger 201, spirally flows from top to bottom, and exchanges heat with the flowing air at the same time to exchange heat with the refrigerant copper pipe.

[0028] The working principle of the split air conditioner in this embodiment is the same as that of the prior art air conditioner. A closed refrigeration and heating circuit is formed between the indoor unit and the outdoor unit. The main process of the refrigeration circuit in the prior art is: gas-liquid separator 9-compressor 10 (the refrigerant is compressed into high-temperature and high-pressure steam)-electromagnetic four-way valve 11-outdoor unit fluorine medium heat exchanger 201 (the refrigerant is cooled to become a constant-temperature and high-pressure liquid by heat release)-expansion valve 5 (the refrigerant is throttled to become a low-temperature and low-pressure liquid by pressure reduction)-indoor unit sleeve type heat exchanger 101 (the liquid refrigerant is evaporated into a low-temperature and low-pressure steam by heat absorption)-electromagnetic four-way valve 11-gas-liquid separator 9. The main process of the heating circuit in the prior art is: gas-liquid separator 9-compressor 10 (the refrigerant is compressed into high-temperature and high-pressure steam)-electromagnetic four-way valve 11-indoor unit sleeve type heat exchanger 101 (the liquid refrigerant is cooled to become a constant-temperature and high-pressure liquid by heat release)-expansion valve 5 (the refrigerant is throttled to become a low-temperature and low-pressure liquid by pressure reduction)-outdoor unit fluorine medium heat exchanger 201 (the liquid refrigerant is evaporated into a low-temperature and low-pressure steam by heat absorption)-electromagnetic four-way valve 11-gas-liquid separator 9. The cold and heat exchange between the refrigerant and the air of the indoor unit and the outdoor unit in the prior art is realized by using a surface cooler. The refrigerant and the air are separated by a layer of refrigerant pipe wall and fins, resulting in low heat exchange efficiency and low energy efficiency ratio. With the development of industry, the air quality in cities is poor, and the dust and formaldehyde in the air cannot be solved by using the air conditioner of the prior art. The indoor unit heat exchange structure 1 in the present design is additionally provided with an indoor unit water curtain heat exchanger 102, and the outdoor unit heat exchange structure 2 is additionally provided with an outdoor unit water curtain heat exchanger 202. Since the water curtain can directly contact the air to perform heat exchange, the heat exchange efficiency of direct heat exchange is high, and the water medium can carry away the dust and formaldehyde in the air. Therefore, the indoor unit sleeve type heat exchanger 101 in the present design first performs heat exchange with the indoor unit water curtain heat exchanger 102, and the indoor unit water curtain heat exchanger 102 performs heat exchange with the indoor air. In the refrigeration process, the indoor unit sleeve type heat exchanger 101 evaporates and absorbs heat, absorbs the heat in the water medium of the indoor unit water curtain heat exchanger 102, causes the temperature of the water medium of the indoor unit water curtain heat exchanger 102 to drop, and the water medium contacts the indoor air to perform heat exchange, so that the temperature of the indoor air drops, and the water medium carries away the dust and formaldehyde (formaldehyde is easily dissolved in water) in the air, thereby achieving the purification effect on the air. At the same time, the outdoor unit fluorine medium heat exchanger 201 releases heat, the outdoor unit fluorine medium heat exchanger 201 contacts the outdoor unit water curtain heat exchanger 202, and part of the heat is transferred to the outdoor unit water curtain heat exchanger 202. The outdoor unit fluorine medium heat exchanger 201 and the water curtain of the outdoor unit water curtain heat exchanger 202 form a large-area water net, so the heat dissipation area is increased, and the heat exchange efficiency of the outdoor unit is greatly improved. The outdoor unit fluorine medium heat exchanger 201 is arranged in the water curtain, so that the surface of the outdoor unit fluorine medium heat exchanger 201 is effectively kept clean and dust-free.
