Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, and in particular to an air treatment system and an air treatment method. BACKGROUND

[0002] In the working process of an air compressor, the cooling of compressed air generates a large amount of waste heat, which is usually discharged to the outside by water cooling or air cooling, resulting in not only energy waste but also an increase in ambient temperature and aggravation of the greenhouse effect. The air inlet of the air compressor needs to be dehumidified, and the higher the air humidity, the greater the working pressure of the air compressor. Common dehumidification methods mainly include refrigeration dehumidification, adsorbent dehumidification, and absorbent dehumidification.

[0003] Traditional air conditioning systems usually adopt combined temperature and humidity processing. To meet the humidity requirement, condensation dehumidification is often used for dehumidification. When condensation dehumidification is used for dehumidification, the temperature of the cold water needs to be lower than the dew point temperature of the air in the space to be adjusted. This condensation dehumidification requires a low evaporation temperature of the refrigeration host, resulting in waste of energy utilization grade. When condensation dehumidification is used for dehumidification, a large amount of condensate water and mold are generated during equipment operation, which seriously affects the air quality of the space to be adjusted.

[0004] The above statements are only used to provide background technical information related to the present application, and do not necessarily constitute the prior art. SUMMARY

[0103] As Figure 1As shown, the air treatment system provided by the embodiments of the present application mainly comprises an air compressor 2, a first solution dehumidifier 1, an air conditioning device 11, a heat exchange device, and a solution regenerator 6. The air compressor 2 is configured to compress the first air into compressed air output.

The solution regenerator 6 is configured to regenerate the dilute solution into concentrated solution by using the heat energy of the compressed air.

[0104] In the air treatment system of the embodiments of the present application, the solution regenerator 6 is configured to regenerate the dilute solution into concentrated solution by using the heat energy of the compressed air, which can dehumidify the first air to be compressed by the air compressor 2 and the second air to be processed by the air conditioning device 11 by using the concentrated solution, and can fully utilize the heat in the compressed air to dehumidify the first air to be compressed by the air compressor 2 and the second air to be adjusted in temperature and humidity by the air conditioning device 11 respectively or simultaneously, which on the one hand helps to reduce the waste of heat energy of the compressed gas output by the air compressor 2, and on the other hand helps to reduce the energy consumption required for dehumidifying the first air and the second air.

[0160] The regulating device comprises a first regulating valve 19, a second regulating valve 20, a third regulating valve 21, a fourth regulating valve 22, a fifth regulating valve 23, a sixth regulating valve 29, a make-up valve 24, a dilute solution pump 7 and a concentrated solution pump 9.

[0161] The working principle of the solution regeneration of the air treatment system of the embodiment is as follows:

[0162] The heat exchange device comprises a first heat exchanger 4 and a second heat exchanger 5, which are arranged in parallel, and water is used as the heat carrier fluid to drive the solution regeneration by carrying the waste heat of the compressed air output by the air compressor 2. The first air after being dehumidified by the first solution dehumidifier 1 enters the air compressor 2 to be compressed to form compressed air output. At this time, the compressed air is an oil-gas mixture because the lubricating oil of the air compressor 2 is mixed in the compressed air during the compression process. The compressed air enters the oil-gas separator 3 to be separated. The gas part after the separation is the de-oiled compressed air. The de-oiled compressed air exchanges heat with the low-temperature circulating water in the first heat exchanger 4 and the low-temperature circulating water pipe 14 as part of the heat carrier fluid. The separated lubricating oil exchanges heat with the low-temperature circulating water in the second heat exchanger 5 and the low-temperature circulating water pipe 14 as part of the heat carrier fluid. After the low-temperature circulating water exchanges heat with the de-oiled compressed gas and the lubricating oil in the first heat exchanger 4 and the second heat exchanger 5 respectively, the high-temperature circulating water is formed by converging and flows into the high-temperature circulating water pipe 15. The high-temperature circulating water is introduced into the solution regenerator 6 to drive the solution regeneration. The regenerated concentrated solution is stored in the concentrated solution reservoir 8. The concentrated solution is transported to the first solution dehumidifier 1 and the second solution dehumidifier 113 of the air conditioner 11 by the concentrated solution pump 9 to perform the solution dehumidification work. After the dehumidification work is completed, the dilute solution formed is stored in the dilute solution reservoir 10. The dilute solution is transported to the regenerator 6 by the dilute solution pump 7 and is regenerated by the high-temperature circulating water 15. The regenerated concentrated solution is stored in the concentrated solution reservoir 8, and the cycle is repeated. The make-up valve 24 is only opened at the beginning of the operation of the air treatment system to add water and when water needs to be added. It is closed at other times.

[0163] The working process of the air dehumidification at the air inlet end of the air compressor 2, i.e. the first air dehumidification, in the air treatment system of the embodiment is as follows:

[0164] The first regulating valve 19 and the third regulating valve 21 are opened, and the concentrated solution is delivered from the concentrated solution storage tank 8 to the first solution dehumidifier 1 through the concentrated solution pump 9 to dehumidify the first air. The dehumidified first air enters the air compressor 2 to be compressed, and the generated compressed air (oil-gas mixture) enters the oil-gas separator 3 to be separated. The dehumidified and deoiled compressed gas after heat exchange with the low-temperature circulating water in the first heat exchanger 4 enters the dehumidifier 12 to be dehumidified, and the dehumidified and deoiled compressed gas is stored in the gas storage tank 13. The concentrated solution dehumidifies the first air in the first solution dehumidifier 1, and after absorbing the water vapor in the first air, the concentration of the concentrated solution is reduced to become a dilute solution, which is stored in the dilute solution storage tank 10.

[0165] The working process of the air dehumidification of the air handling system air conditioning equipment 11 of the embodiment is as follows.

[0166] The second regulating valve 20 and the fourth regulating valve 22 are opened, and the concentrated solution is delivered from the concentrated solution storage tank 8 to the second solution dehumidifier 113 of the air conditioner 11 through the concentrated solution pump 9. The new air and / or return air are mixed in the air mixing section 111, and the second air is filtered by the filter 112 and then enters the second solution dehumidifier 113 to be dehumidified by the solution. The dehumidified second air is cooled in the surface cooler 114, and then is sent to the regulated space by the fan of the fan section 115. The concentrated solution absorbs the water vapor in the second air in the second solution dehumidifier 113, and the concentration of the concentrated solution is reduced to become a dilute solution, which is stored in the dilute solution storage tank 10.

[0167] The feasible steps of the air handling method of the air handling system under different conditions are as follows.

[0168] In the following description, φ1 is the preset maximum relative humidity of the first air, φq is the relative humidity of the first air, Δφ1 is the allowable fluctuation value of the relative humidity of the first air, φh is the relative humidity of the second air, φ0 is the target relative humidity of the regulated space, φn is the relative humidity of the regulated space, Δφ0 is the allowable fluctuation value of the relative humidity of the regulated space, Th is the temperature of the second air, T0 is the target temperature of the regulated space, Tn is the temperature of the regulated space, and ΔT is the allowable fluctuation value of the temperature of the regulated space. Among them, φ1, Δφ1, φ0, Δφ0, T0 and ΔT are preset values set according to the regulation needs, and φq, φh, φn, Th and Tn are monitored by the first temperature and humidity sensor 25, the second temperature and humidity sensor 26 and the humidity sensor 27.

[0169] When the air entering the air compressor 2, i.e. the first air, needs to be dehumidified, the following air handling method can be used.

[0170] The first regulating valve 19, the second regulating valve 20, the third regulating valve 21, the fourth regulating valve 22 and the fifth regulating valve 23 are all opened, and the supplementary valve 24 is closed.

[0171] When φq≥φ1, it means that the first solution dehumidifier 1 is insufficient to dehumidify the first air, and the dehumidification amount of the first air needs to be increased. The opening of the first regulating valve 19 can be increased to increase the flow of concentrated solution input into the first solution dehumidifier 1, so that the relative humidity of the first air entering the air compressor 2 satisfies the condition φq<φ1 and φ1-φq≤△φ1; if the first regulating valve 19 is adjusted to the maximum preset opening and still cannot satisfy the condition φq<φ1 and φ1-φq≤△φ1, the concentrated solution pump 9 is operated at a higher frequency, for example, multiple times of frequency increase in stages, each time the frequency can be increased by the same amplitude or different amplitudes, for example, each time the frequency is increased by 1HZ, until the condition φq<φ1 and φ1-φq≤△φ1 is satisfied.

[0172] When φq<φ1 and φ1-φq>△φ1, it means that the first air before entering the air compressor 2 is over-dehumidified, and the dehumidification amount of the first air needs to be reduced. The concentrated solution pump 9 can be operated at a lower frequency, for example, multiple times of frequency decrease in stages, each time the frequency can be decreased by the same amplitude or different amplitudes, for example, each time the frequency is decreased by 1HZ, until the relative humidity of the first air entering the air compressor 2 satisfies the condition φ1-φq≤△φ1. If the frequency of the concentrated solution pump 9 is reduced to the preset minimum frequency, for example, 30HZ, and still cannot satisfy the condition φ1-φq≤△φ1, the opening of the first regulating valve 19 is reduced to reduce the flow of concentrated solution input into the first solution dehumidifier 1, until the condition φ1-φq≤△φ1 is satisfied.

[0173] When the temperature and humidity of the second air of the air conditioning equipment 11 are independently controlled, the air conditioning equipment 11 can adopt the following air treatment method when operating in the cooling season.

[0174] When φh>φ0 and φn>φ0 and φn-φ0>△φ0, it means that the second solution dehumidifier 113 is insufficient to dehumidify the second air, and the dehumidification amount needs to be increased. The opening of the second regulating valve 20 can be increased to increase the flow of concentrated solution input into the second solution dehumidifier 113, until the condition φn-φ0≤△φ0 is satisfied. If the second regulating valve 20 is adjusted to the maximum preset opening and still cannot satisfy the condition φn-φ0≤△φ0, the concentrated solution pump 9 is operated at a higher frequency, for example, multiple times of frequency increase in stages, each time the frequency can be increased by the same amplitude or different amplitudes, for example, each time the frequency is increased by 1HZ, until the condition φn-φ0≤△φ0 is satisfied.

[0175] When φh > φ0, φn < φ0 and φ0-φn > Δφ0, it means that the second air is over dehumidified in the second solution dehumidifier 113, and the dehumidification amount needs to be reduced. The concentrated solution pump 9 can be operated at a lower frequency, and each time the frequency can be reduced by the same amplitude or different amplitudes, for example, each time the frequency is reduced by 1HZ, until the condition φ0-φn≤Δφ0 is met. If the frequency of the concentrated solution pump 9 is reduced to a predetermined minimum frequency, for example, 30HZ, and the condition φ0-φn≤Δφ0 cannot be met, the opening of the second regulating valve 20 is reduced to reduce the flow of the concentrated solution into the second solution dehumidifier 113, until φ0-φn≤Δφ0.

[0176] When Th > T0, Tn > T0 and Tn-T0 > ΔT, it means that the load of the conditioned space is large at this time, and the refrigerating capacity of the cooling coil 114 is insufficient, and the heat exchange amount needs to be increased. The opening of the fifth regulating valve 23 can be increased to increase the flow of chilled water, until Tn-T0≤ΔT. When Th > T0, Tn < T0 and T0-Tn > ΔT, it means that the load of the conditioned space is small at this time, and the refrigerating capacity of the cooling coil 114 is excessive, and the heat exchange amount needs to be reduced. The opening of the fifth regulating valve 23 can be reduced to reduce the flow of chilled water, until T0-Tn≤ΔT.

[0177] When the temperature and humidity of the second air of the air conditioning equipment 11 are independently controlled, the air handling method of the air conditioning equipment 11 in the transition season can be as follows.

[0178] When φh > φn, and |φn-φ0| > |Δφ0|, Th≤Tn and |Tn-T0|≤|ΔT|, it means that the load of the conditioned space is small, and the heat can be dissipated through the envelope structure, but the humidity of the second air is too high, and the environment of the conditioned space is humid, and the dehumidification intensity of the second air needs to be increased to ensure the comfort of the conditioned space. The fifth regulating valve 23 can be closed, and the opening of the second regulating valve 20 can be increased to increase the flow of the concentrated solution into the second solution dehumidifier 113, until |φn-φ0|≤|Δφ0|.

[0179] When φh≤φn, and |φn-φ0|≤|Δφ0|, Th≤Tn and |Tn-T0|≤|ΔT|, it means that the load of the conditioned space is small, and the heat can be dissipated through the envelope structure, and the air conditioning equipment 11 only needs to introduce fresh air into the conditioned space. The second regulating valve 20, the fourth regulating valve 22 and the fifth regulating valve 23 can be closed, the outdoor fresh air enters the air mixing section 111, is filtered by the filter 112, and is sent into the conditioned space by the fan through the fan section 115.

[0180] The effect of solution dehumidification is related to the concentration of the solution, and the solution concentration is too high at room temperature, which needs to be monitored and controlled. At this time, the air handling method is as follows.

[0181] In the following description, C1 is the solution concentration of the regenerated concentrated solution, C0 is the target solution concentration of the regenerated concentrated solution, and AC is the solution concentration fluctuation value of the regenerated concentrated solution. C0 and AC are preset values set according to the adjustment requirements. C1 is monitored by the concentration monitoring device 28.

[0182] When C1 < C0 and C0-C1 > AC, it indicates that the solution concentration is too low, and the dilute solution flow rate needs to be reduced or the high-temperature circulating water temperature needs to be increased to increase the solution concentration. The dilute solution pump 7 can be operated at a lower frequency, for example, by reducing the frequency by 1HZ each time, to reduce the dilute solution flow rate, increase the heating of the unit volume of dilute solution, and satisfy the condition C0-C1≤AC. If the frequency of the dilute solution pump 7 is reduced to the lowest preset frequency, for example, 30HZ, and the condition C0-C1≤AC cannot be met, the opening of the sixth adjustment valve 29 is increased to increase the low-temperature circulating water flow rate, increase the heat exchange amount, and increase the regenerated solution concentration until the condition C0-C1≤AC is met.

[0183] When C1 > C0 and C1-C0 > AC, it indicates that the solution concentration is too high, and the high-temperature circulating water temperature needs to be reduced or the dilute solution flow rate needs to be increased. The opening of the sixth adjustment valve can be reduced to reduce the low-temperature circulating water flow rate, reduce the heat exchange amount, and reduce the regenerated solution concentration until the condition C1-C0≤AC is met. If the opening of the sixth adjustment valve 29 is adjusted to the lowest preset opening and the condition C1-C0≤AC cannot be met, the concentrated solution pump 9 is operated at a higher frequency, for example, by increasing the frequency by 1HZ each time, to increase the dilute solution flow rate, reduce the heating of the unit volume of dilute solution, and reduce the regenerated solution concentration until the condition C0-C1≤AC is met.

[0184] To ensure the stability of the air compressor 2, the dehumidification requirement of the first air of the air compressor 2 is preferentially met.

[0185] To avoid frequent adjustment, the operation parameters of the air treatment system can be monitored once every predetermined time period, for example, 10 minutes, 20 minutes, 30 minutes, etc., and the operation parameters of the air treatment system can be adjusted once every predetermined time period.

[0186] According to the above description, the air treatment device and the air treatment method of the embodiments of the present application have at least one of the following advantages:

[0187] The waste heat generated when the compressed air of the air compressor is cooled is used to drive the regeneration of the dehumidification solution, which is beneficial to reducing energy waste and also beneficial to reducing the greenhouse effect caused by energy waste.

[0188] The regenerated concentrated solution is used for dehumidifying the first air at the air inlet end of the air compressor, which ensures a good working environment for the air compressor and is beneficial to reducing the power consumption of the air compressor.

[0189] The second air to be regulated by the air conditioning equipment is dehumidified by the solution dehumidification method, and a cold source with a relatively high temperature can be used to cool the air conditioning system, for example, the supply water temperature of the chilled water can be increased from 7 DEG C required by the conventional air conditioning equipment to 18 DEG C, so as to improve the energy efficiency of the refrigeration host and reduce the energy consumption of the air conditioning system.

[0190] The air conditioning equipment dehumidifies by the solution dehumidification method, and the temperature of the cold source does not need to be lower than the dew point temperature of the air, so that the air conditioning equipment does not produce condensate water, which is beneficial to reduce the breeding of biological pollutants such as mold and improve the air quality of the regulated space. In addition, the solution dehumidification method is similar to the wet dust collector, which can filter the dust in the air to a certain extent and purify the air.

[0191] The second air to be regulated by the air conditioning equipment is dehumidified by the solution dehumidification method, which is beneficial to realize the independent control of temperature and humidity, so as to reduce the waste of energy utilization grade when the temperature and humidity are jointly controlled.

[0193] The above description of each embodiment tends to emphasize the differences between each embodiment, and the same or similar parts can be referred to each other, and for the sake of brevity, the same or similar parts will not be described here.

[0194] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the specific implementation of the present application can be modified or some technical features can be replaced by equivalent, which should be covered in the technical solution range of the present application claimed.
