[0023] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0024] The present embodiment provides an air conditioner indoor unit, as shown in Figure 1 and Figure 2 , comprising a shell 100, an air duct 110 in the shell 100 is provided with a deodorization assembly 200, the deodorization assembly 200 comprises an ozone generator 210 and an ultraviolet light source 220, the ultraviolet light source 220 is located at the leeward side of the ozone generator 210, and the ultraviolet light source 220 is configured to: irradiate the ozone generated by the ozone generator 210 to make the ozone photolyze to generate atomic active oxygen for deodorization.

[0025] In the air conditioner indoor unit provided by the present embodiment, the ozone generator 210 is used to generate ozone, the ultraviolet light source 220 is used to irradiate ultraviolet light capable of decomposing ozone into atomic active oxygen, and the radiation area thereof is located at the leeward side of the ozone generator 210; when the air conditioner indoor unit is running, the deodorization assembly 200 is started, the ozone generator 210 generates ozone and releases the ozone into the air duct 110, and the ultraviolet light source 220 forms an ultraviolet light irradiation area at the leeward side of the ozone generator 210; at the same time, the air in the indoor environment enters the air duct 110 through the air inlet 120 of the air duct 110 under the driving of the fan 400, and then is heated by the heat exchanger 300 of the air conditioner indoor unit and then is blown outwards through the air outlet 130 of the air duct 110, wherein, in the process of the airflow flowing through the air duct 110, part of the airflow flows through the ozone generator 210 and the surrounding area thereof, and the ozone released by the ozone generator 210 is blown to the ultraviolet light irradiation area in the flowing process, and the ozone occurs photolysis reaction under the irradiation of the ultraviolet light to generate excited singlet oxygen molecules O2( 1 Δ g ) and singlet oxygen atoms O( 1 D), and the specific photolysis reaction formula is as follows:

[0026] O3+hν(λ<310nm)→O2( 1 Δg )+O( 1 D)(Formula 1)

[0027] In the formula, h is Planck's constant; v is the frequency of the ultraviolet light emitted by the ultraviolet light source, Hz; hv is the energy of the ultraviolet light emitted by the ultraviolet light source, J; and λ is the wavelength of the ultraviolet light emitted by the ultraviolet light source, nm, and λ < 310 nm.

[0028] The singlet oxygen atom O( 1 D) is an atomic active oxygen with high oxidation reactivity, and the atomic active oxygen contacts the odor molecules in the air duct 110 and oxidizes and decomposes the odor molecules to achieve deodorization. For an equal amount of ozone, the atomic active oxygen is first oxidized and decomposed, and then the oxidation and decomposition speed of the odor molecules by the atomic active oxygen is much greater than the oxidation and decomposition speed of the odor molecules by the ozone directly, thereby greatly improving the deodorization effect of the air conditioner indoor unit on the indoor environment.

[0029] Specifically, taking the representative odor molecule trimethylamine ((CH3)3N) as an example, research shows that the reaction speed constant of the atomic active oxygen O( 1 D), ozone (O3) and trimethylamine ((CH3)3N) is as shown in the following table:

[0030]

[0031] As can be seen from the above table, the reaction speed constant of the atomic active oxygen O( 1 D) and trimethylamine ((CH3)3N) is 2.77 x 10 6 times that of ozone (O3) and trimethylamine ((CH3)3N).

[0032] It can be seen that in the air conditioner indoor unit provided in this embodiment, on the one hand, the ozone is first oxidized and decomposed into the atomic active oxygen O( 1 D) with high oxidation reactivity by the ultraviolet light source, and then the atomic active oxygen O( 1 D) is used to oxidize and decompose the odor molecules, and the oxidation and decomposition speed is much greater than the oxidation and decomposition speed of the odor molecules by the ozone directly, thereby greatly improving the deodorization effect of the air conditioner indoor unit on the indoor environment; on the other hand, the ultraviolet light source 220 is arranged at the leeward side of the ozone generator 210, and during operation, the ozone generated by the ozone generator 210 can move to the ultraviolet light radiation region formed downstream by the ultraviolet light source 220 under the action of the airflow, thereby ensuring effective irradiation of the ultraviolet light on the ozone, and accordingly ensuring the photolysis efficiency of the ozone under the action of the ultraviolet light, and further ensuring the deodorization effect of the air conditioner indoor unit on the indoor environment by improving the yield of the atomic active oxygen.

[0033] In the embodiment, the ozone generator 210 generates A ozone molecules per unit time, the product of the photon amount n radiated by the ultraviolet light source 220 per unit time and the quantum yield φ of the atomic active oxygen generated by the photolysis of ozone is B, and A≤B. 1 As can be seen from formula 1, the ozone is photolyzed to generate excited singlet oxygen molecules O2( 1 D) and singlet oxygen atoms O( 1 D) under the action of ultraviolet light radiation energy, wherein the singlet oxygen atom O( 1 D) is atomic active oxygen, and the quantum yield φ is approximately 1. When the product B of the photon amount n radiated by the ultraviolet light source 220 per unit time and the quantum yield φ of the atomic active oxygen generated by the photolysis of ozone is greater than or equal to the ozone molecule generation amount A of the ozone generator 210 per unit time, it is indicated that the ozone generated by the ozone generator 210 can be completely decomposed by the ultraviolet light radiated by the ultraviolet light source 220, thereby improving the yield of atomic active oxygen and further ensuring the deodorization effect of the deodorization assembly 200 and the air conditioner indoor unit on the indoor environment.

[0034] The ultraviolet light source 220 can specifically be an ultraviolet lamp with equal ultraviolet light intensity. Figure 3 The first flowchart of the method for determining the number of ultraviolet lamps in the air conditioner indoor unit is provided.

[0035] As shown in Figure 3 , the method comprises the following steps.

[0036] S302 obtains the ozone molecule generation amount A of the ozone generator per unit time, the photon amount n radiated by a single ultraviolet lamp per unit time, and the quantum yield φ of the atomic active oxygen generated by the photolysis of ozone.

[0037] When the deodorization assembly is running, A is the rate of ozone molecules generated by the ozone generator, n is the rate of photons radiated by a single ultraviolet lamp, and φ is the quantum yield of the atomic active oxygen generated by the photolysis of ozone under the radiation of the ultraviolet lamp.

[0038] S304 calculates the positive integer value of the number m of ultraviolet lamps according to the relationship A / (n·φ)≤m<1+A / (n·φ).

[0039] The m ultraviolet lamps collectively radiate the ozone generated by the ozone generator, that is, the m ultraviolet lamps collectively serve as the ultraviolet light source, B = n · φ · m, in order to ensure that the ozone can be completely decomposed under the radiation of the m ultraviolet lamps to generate the maximum amount of atomic active oxygen, A ≤ B, then m ≥ A / (n · φ), wherein, when A / (n · φ) is a positive integer, it can be known from A / (n · φ) ≤ m < 1 + A / (n · φ) that m = A / (n · φ), that is, A = B, the photons generated by the m ultraviolet lamps collectively radiating can just satisfy the decomposition of the ozone generated by the ozone generator, so that the ozone can be completely decomposed; when A / (n · φ) is a decimal, m is a positive integer between A / (n · φ) and 1 + A / (n · φ), at this time, A < B, the photons generated by the m ultraviolet lamps collectively radiating can have a surplus to satisfy the decomposition of the ozone generated by the ozone generator, so that the ozone can be completely decomposed; then the number of ultraviolet lamps determined by the above determination method can make the ozone generated by the ozone generator completely decomposed under the radiation of the ultraviolet light source, so as to ensure the highest generation efficiency of the atomic active oxygen, ensure the deodorization effect of the deodorization assembly and the air conditioner indoor unit, and effectively reduce the energy waste, cost increase and ultraviolet light leakage caused by too many ultraviolet lamps, thereby reducing the operation cost of the air conditioner indoor unit and improving the use safety of the air conditioner indoor unit.

[0040] Specifically, in the embodiment, the amount of photons radiated by a single ultraviolet lamp per unit time n is obtained by the following steps: obtaining the ultraviolet light intensity P of a single ultraviolet lamp and the energy E of a single ultraviolet photon; calculating the number of photons N radiated by a single ultraviolet lamp per unit time according to the ultraviolet light intensity P of the ultraviolet lamp, the energy E of a single ultraviolet photon and the quantum yield φ; and taking the ratio of the number of photons N radiated by a single ultraviolet lamp per unit time to the Avogadro constant NA as the amount of photons n radiated by a single ultraviolet lamp per unit time.

[0041] The ultraviolet light intensity P of a single ultraviolet lamp can be obtained according to the model parameters of the ultraviolet lamp, the energy E of a single ultraviolet photon can be calculated by the following formula 2, and the quantum yield φ is approximately 1 according to formula 1; formula 2 is as follows:

[0042] E = hc / λ (formula 2)

[0043] In the formula, E is the energy of a single ultraviolet photon, J; h is Planck's constant, which is 6.6 x 10 -34 Js; c is the speed of light, which is 3.0 x 10 8 m / s; λ is the wavelength of the ultraviolet light source irradiating ultraviolet light, nm.

[0044] Then, the number of photons N radiated by a single ultraviolet lamp per unit time is calculated according to formula 3:

[0045] N = (P · t) / (E · φ) (Formula 3)

[0046] In the formula, N is the number of photons radiated by a single ultraviolet lamp per second N; P is the ultraviolet light intensity of a single ultraviolet lamp P; t is the unit time, s, which is taken as 1 s; E is the energy of a single ultraviolet photon J; and φ is the quantum yield of atomic active oxygen generated by photolysis of ozone under ultraviolet lamp radiation. Among them, P·t is the light energy radiated by a single ultraviolet lamp per second, and E·φ is the energy of the ultraviolet light required for a single ozone molecule to generate a single atomic active oxygen.

[0047] Continuously, the amount of photons radiated by a single ultraviolet lamp per unit time n is calculated according to Formula 4:

[0048] n = 3600 · N / NA (Formula 4)

[0049] In the formula, n is the amount of substance of photons radiated by a single ultraviolet lamp per hour mol / h; N is the number of photons radiated by a single ultraviolet lamp per second N; and NA is the Avogadro constant, taken as 6.0×10 23 .

[0050] The ozone molecule production amount A of the ozone generator per unit time can be set as needed, such as setting the ozone production speed of the ozone generator per hour as b (mg / h), and according to the ozone molecule weight 48, the ozone molecule production amount A of the ozone generator per hour can be calculated as A = b × 10 -3 / 48 (mol / h).

[0051] Then according to A / (n·φ)≤m<1+A / (n·φ), the positive integer value of m can be calculated, so as to calculate the minimum number of ultraviolet lamps that can make the ozone generated by the ozone generator completely decompose, and accordingly, on the basis of ensuring the deodorization effect of the air conditioner indoor unit on the indoor environment, the operation cost of the ultraviolet lamp and the air conditioner indoor unit is reduced.

[0052] The following is an example calculation with specific numerical values:

[0053] Take the ozone production speed of the ozone generator per hour as 80 mg / h, the ultraviolet light wavelength of a single ultraviolet lamp is λ = 280 nm, the ultraviolet light intensity of a single ultraviolet lamp is P = 110 mW, the Planck constant h = 6.6×10 -34 Js, and the speed of light c = 3.0×10 8 m / s.

[0054] According to Formula 2, the energy E of a single ultraviolet photon can be calculated:

[0055] E = hc / λ = 7.1×10 -19 J;

[0056] The number of photons radiated per unit time by a single ultraviolet lamp N can be calculated according to Formula 3:

[0057] N = (P · t) / (E · φ) = 1.5 × 10 17

[0058] The amount of photons radiated per unit time by a single ultraviolet lamp n can be calculated according to Formula 4:

[0059] n = 3600 · N / NA = 0.0009 mol / h;

[0060] The amount of ozone molecules generated per hour by the ozone generator A = b × 10 -3 / 48 = 0.0016 mol / h.

[0061] From A / (n · φ) ≤ m < 1 + A / (n · φ) and m being a positive integer, we have:

[0062] 1.78 ≤ m < 2.78, so m = 2, and the number of ultraviolet lamps in the air conditioner indoor unit is 2, which can effectively reduce the number of ultraviolet lamps and reduce the operating cost of the air conditioner indoor unit while meeting the complete decomposition of ozone.

[0063] In this embodiment, the wavelength range of the ultraviolet light source 220 is 200 nm to 310 nm. When the wavelength of the ultraviolet light radiated by the ultraviolet light source 220 is less than 200 nm, in addition to the decomposition of ozone into atomic active oxygen under the radiation of ultraviolet light, the oxygen in the air duct 110 can also be converted into ozone under the radiation of ultraviolet light in this wavelength range. The reaction not only consumes the energy of ultraviolet light, but also may increase the production of ozone, leading to the occurrence of the situation that ozone cannot be fully decomposed and escapes.

[0064] Specifically, in this embodiment, the wavelength range of the ultraviolet light source 220 can be 240 nm to 280 nm. The ultraviolet light in this wavelength range not only serves to decompose ozone, but also has a sterilization function, which can kill bacteria in the air duct 110, thereby improving the functionality of the air conditioner indoor unit.

[0065] In this embodiment, as Figure 1 and Figure 2 ​As shown, the leeward side of the ozone generator 210 is surrounded by a reaction cylinder 230, and the ultraviolet light source 220 is accommodated in the reaction cylinder 230. During operation, on the one hand, the ozone generated by the ozone generator 210 can flow into the reaction cylinder 230 on the leeward side thereof under the driving of the airflow, and the ultraviolet light source 220 forms a radiation area in the reaction cylinder 230, so as to sufficiently radiate the ozone entering the reaction cylinder 230, correspondingly improve the decomposition efficiency of the ozone, improve the efficiency of generating atomic active oxygen, and reduce the residual amount of ozone; on the other hand, the reaction cylinder 230 surrounds the ultraviolet light source 220, which can block the ultraviolet light to reduce the leakage of the ultraviolet light, improve the utilization rate of the ultraviolet light, and reduce the adverse effects of the leakage of the ultraviolet light on the outside, especially on the eyes of the user.

[0066] In the embodiment, a blocking member can be further arranged around the ultraviolet light source 220 to further reduce the leakage of the ultraviolet light. Specifically, the blocking member can be located on the side of the ultraviolet light source 220 facing the air inlet 120 and the air outlet 130, and the blocking member can reduce the obstruction of the airflow on the basis of ensuring effective blocking of the leakage of the ultraviolet light from the air inlet 120 and the air outlet 130. Preferably, the ultraviolet light source 220 can be an ultraviolet LED which is free of harmful substances such as mercury and has low power consumption, small size, and high installation freedom; and the ultraviolet light source 220 can adopt a light source with a pointing angle as small as possible to reduce light diffusion.

[0067] In the embodiment, a filter screen is arranged at the air outlet 130 of the air duct 110, and the filter screen is provided with a catalyst for decomposing ozone. When the ultraviolet light source 220 fails to light, the ozone generated by the ozone generator 210 can be decomposed under the action of the catalyst when the ozone passes through the filter screen along with the airflow, so as to reduce the secondary pollution of the ozone to the indoor environment and the damage of the ozone to the health of the user, thereby improving the use safety of the air conditioner indoor unit.

[0068] In the embodiment, the method for generating ozone by the ozone generator 210 can be a discharge method, oxygen irradiation of 185 nm vacuum ultraviolet light, etc., and the discharge method is preferably selected to realize the miniaturization and light weight of the ozone generator 210, so as to facilitate the arrangement of the ozone generator 210 in the air duct 110; and the discharge method can include corona discharge, silent discharge, and surface discharge, and the corona discharge and the silent discharge are more easily applied.

[0069] Specifically, in the embodiment, the air conditioner indoor unit is a wall-mounted air conditioner indoor unit, the deodorization assembly 200 is located between the front panel 140 of the shell 100 and the heat exchanger 300, and the ozone generator 210 faces the front panel 140 and the ultraviolet light source 220 faces the heat exchanger 300. As shown in FIG. 1, the ozone generator 210 is arranged on the front panel 140, and the ultraviolet light source 220 is arranged on the heat exchanger 300. Figure 1As shown, the air inlet 120 of the indoor unit of the wall-mounted air conditioner is located at the top thereof, the air outlet 130 is located at the bottom front side thereof, the deodorization assembly 200 is arranged between the front panel 140 and the heat exchanger 300, when in operation, the airflow flows into the air duct 110 from top to bottom, and after heat exchange with the heat exchanger 300 from the windward side of the heat exchanger 300, the airflow flows out from the air outlet 130 downward; wherein the wind speed in the region between the front panel 140 and the heat exchanger 300 is relatively small, the airflow with low speed first flows to the ozone generator 210, and the ozone generated by the ozone generator 210 flows through the radiation region of the ultraviolet light source 220 at a relatively low speed, thereby ensuring the contact time of the ozone and the ultraviolet light, so that the ozone can be fully decomposed, and the decomposition rate of the ozone is further improved. In addition, the ultraviolet light source 220 is arranged between the front panel 140 and the heat exchanger 300, and the two can effectively block the ultraviolet light, thereby effectively reducing the occurrence of ultraviolet light leakage.

[0070] Of course, in other embodiments, the deodorization assembly 200 can also be arranged at any other position of the air duct 110, and the indoor unit of the air conditioner can also be a ceiling recessed type, a floor type, and all forms of indoor units of air conditioners with air inlet and air outlet functions.

[0071] In the embodiment, the shell 100 is provided with a controller and a detection assembly for detecting the opening state of the front panel 140, and the detection assembly, the ozone generator 210 and the ultraviolet light source 220 are all communicatively connected to the controller. When the indoor unit of the air conditioner is in the shutdown or standby state, the controller controls the ozone generator 210 and the ultraviolet light source 220 to be in the closed state; during the operation of the indoor unit of the air conditioner, the detection assembly detects the opening state of the front panel 140 in real time, and feeds back the detected state signal to the controller, and the controller adjusts the on-off state of the ozone generator 210 and the ultraviolet light source 220 according to the opening state of the front panel 140 represented by the received state signal; specifically, when the detection assembly detects that the front panel 140 is in the closed state, the controller controls the ozone generator 210 and the ultraviolet light source 220 to maintain the current operating state accordingly; when the detection assembly detects that the front panel 140 is in the open state, the controller controls the ozone generator 210 and the ultraviolet light source 220 to be closed accordingly, so as to reduce the occurrence of the situation that the ozone generated by the ozone generator 210 and the ultraviolet light radiated by the ultraviolet light source 220 leak from the front and cause harm to the operator, thereby improving the use safety of the indoor unit of the air conditioner.

[0072] Figure 4 The second flowchart of the method for determining the number of ultraviolet lamps in the indoor unit of the air conditioner provided in the embodiment of the utility model is shown in the figure. Figure 4 The method comprises the following steps:

[0073] S402 acquiring the ozone molecule generation amount A of the ozone generator per unit time and the quantum yield φ of the ozone photolysis to generate atomic active oxygen in the indoor unit of the air conditioner.

[0074] S404 obtains the ultraviolet light intensity P of a single ultraviolet lamp and the energy E of a single ultraviolet photon;

[0075] S406 calculates the number N of photons radiated per unit time by a single ultraviolet lamp according to the following formula, and takes the ratio of N to Avogadro's constant NA as the photon amount n radiated per unit time by a single ultraviolet lamp:

[0076] N = (P·t) / (E·φ) ;

[0077] S408 calculates the positive integer value of the number m of ultraviolet lamps according to the relationship A / (n·φ) ≤ m < 1 + A / (n·φ).

[0078] Thus, the minimum number of ultraviolet lamps is obtained.

[0079] The embodiment also provides an air conditioner, which comprises an air conditioner outdoor unit and the air conditioner indoor unit.
