Description
Technical Field
The invention belongs to the technical field of household air conditioners, and particularly relates to a temperature and humidity adjusting device for an air conditioner. The invention further comprises an air conditioner comprising the temperature and humidity regulating device, and a temperature and humidity regulating control system and a temperature and humidity regulating control method based on the temperature and humidity regulating device.
Background
With the continuous improvement of the living standard of people, the air conditioner is increasingly widely applied. Because the indoor space is more humid in summer and the air conditioner is in a refrigerating mode, the comfort level of a user is lower. Therefore, many current air conditioners are provided with a dehumidifying device to solve the problem of indoor air humidity in summer.
The traditional household air conditioner mostly adopts a mode of temperature and humidity joint regulation, namely the temperature and the humidity are cooperatively regulated by the same set of regulating device. When refrigeration and dehumidification are simultaneously realized by utilizing a set of system, in order to remove indoor residual moisture by using a condensation method, the temperature of a cold source needs to be lower than the indoor dew point temperature, and the heat transfer temperature difference and the medium conveying temperature difference are considered, so that the dew point temperature of 16 ℃ needs to be about 7 ℃, namely, the air outlet of an air conditioner needs to be supplied with air at the dew point temperature, the dew point temperature is 16 ℃, and the human body comfort zone in summer is 26 ℃ and the relative humidity is 60%, so that the air outlet temperature needs to be obviously lower than the required refrigeration temperature, and a series of problems are caused.
Firstly, in an air conditioning system, a sensible heat load part accounting for more than half of the total load can be realized by adopting a low-temperature cold source which is shared by heat discharged by a high-temperature cold source and dehumidification at 5-7 ℃ together, so that the waste of energy utilization grade is caused, and the energy waste is caused; meanwhile, although the humidity (moisture content) of the air subjected to condensation dehumidification meets the requirement, the temperature is too low, and the temperature difference between the air temperature and the body surface temperature is large, so that the comfort level is reduced; in addition, the air is cooled and dehumidified in a condensation mode, the ratio of sensible heat to latent heat absorbed by the air can only be changed within a certain range, the ratio of heat to humidity actually required by a building can be changed within a larger range, when the existing same set of system is used for realizing temperature and humidity regulation, the control of humidity can only be sacrificed, the phenomenon of overhigh or overlow indoor relative humidity is caused by only meeting the requirement of indoor temperature, the phenomenon of overhigh relative humidity is caused, the result of overhigh relative humidity is uncomfortable, the set value of the room temperature is further reduced, the thermal comfort is improved by reducing the room temperature, and the energy consumption is unnecessarily increased; finally, current people begin to install more and more fresh air systems, and when fresh air is introduced, too low relative humidity will also result in increased energy consumption for processing the fresh air due to increased enthalpy difference with the outside.

The temperature and humidity regulating device comprises a humidity regulating component and a temperature regulating component which are mutually independent; the humidity adjusting component comprises a fresh air generating component, a first heat exchanger 1 and a fresh air supply port 3, wherein the first heat exchanger 1 is communicated with an air channel of the fresh air generating component, the fresh air supply port 3 is communicated with the first heat exchanger 1 through the first air channel, and a refrigerant inlet of the first heat exchanger 1 is communicated with the first refrigerant component 2 through a refrigerant pipeline; the fresh air generating assembly refers to a structure for generating or introducing fresh air through any mechanism, such as a fan; the inner cavity of the first heat exchanger 1 is communicated with the first refrigerant component 2, and then the refrigerant in the first refrigerant component 2 enters the inner cavity of the first heat exchange gas through a refrigerant pipeline, the fresh air generated by the fresh air generating component enters the heat exchange range of the first heat exchanger 1 through an air channel, and the fresh air temperature is reduced by heat exchange with the cold air in the fresh air generating component, and it is to be understood that the 'air channel communication' of the fresh air generating component and the first heat exchanger 1 means that the fresh air generated by the fresh air generating component enters the heat exchange range of the first heat exchanger 1 on a certain path, and the air channel can be of a virtual structure and can be understood as a circulation path of the fresh air.
The fresh air generating assembly is communicated with the first heat exchanger 1 (namely, fresh air is blown to the heat exchange range of the first heat exchanger 1 from the fresh air generating assembly), and the generated fresh air is input into the first heat exchanger 1, which means that the fresh air passes through the heat exchange surface of the first heat exchanger 1 and exchanges heat with the refrigerant in the first heat exchanger 1, so that the first heat exchanger 1 adjusts the temperature of the fresh air received by the first heat exchanger to a preset value and outputs the fresh air through the fresh air supply outlet 3. In particular, the preset value of the temperature may be a temperature at which the human body feels comfortable, for example, any temperature value between 24 ° and 27 °, preferably 26 °, to conform to the body feeling comfortable temperature of most users.
In the working process, the temperature and humidity regulating device is provided with a temperature regulating part and a humidity regulating part which are relatively independent, so that the limitation of the joint regulation of temperature and humidity is broken, the temperature can be regulated according to the temperature requirement, the humidity can be regulated according to the humidity requirement, and the temperature and the humidity can be independently controlled and regulated; therefore, the air supply temperature of the temperature regulating component can be determined according to the body surface comfort level requirement and the environment temperature requirement without considering the dehumidification working condition, so that the air supply temperature of the temperature regulating component is not required to be set at the dew point temperature, the energy consumption required by the refrigerant component is obviously reduced, the energy consumption of an air conditioner is reduced, and the energy waste is avoided; meanwhile, the air supply temperature of the temperature regulating component can be improved, so that the air supply temperature is close to or equal to the comfort temperature of the body surface of a human body, and the comfort level of the air conditioner is remarkably improved; in addition, the humidity adjusting device capable of being independently adjusted does not need to be limited by temperature adjustment, the precision of humidity adjustment is enhanced, and the adjusting efficiency is higher.
Specifically, the above-mentioned new trend produces the subassembly and includes the new trend fan 41 that communicates with fresh air source through the air intake pipeline, the new trend pipe joint 42 that communicates with air outlet of the said new trend fan 41, and set up the guard piece in the said air intake pipeline; the fresh air pipe joint 42 is communicated with the first heat exchanger 1 through an air duct. Obviously, the connection of the fresh air pipe interface 42 and the air channel of the first heat exchanger also refers to the flow path of the fresh air; when the fresh air fan 41 is started, the fresh air fan sucks outdoor fresh air and isolates harmful solids through the protection piece, and the fresh air enters the position of the first heat exchanger through the fresh air pipe connector 42, is cooled and then is sent into a room to serve as a indoor dehumidifying medium.
In theory, the fresh air generating assembly is not limited to the above structural form, so long as fresh air can be introduced into the device, for example, the fresh air generating assembly can be a fan only, or comprise a fan and a compressed air source communicated with the fan, and the compressed air source is used for replacing outdoor fresh air so as to be used as a standby air source when the quality of outdoor air is poor. The fresh air machine can be indoor or outdoor, when the fresh air machine is arranged indoors, the bypass valve is arranged in front of the fresh air machine, and when the indoor humidity exceeds a set value only, and the target gas does not exceed the set value, the bypass valve can be opened to enable the indoor air to enter the first heat exchanger for humidity adjustment. The fresh air source can be the atmosphere or another compressed air source.
The protection piece can comprise at least one of an electric air valve 43, an insect-proof net 44 and a rainproof shutter 45, preferably all three parts comprise, namely, the rainproof shutter 45 is arranged at the outer end part of an air inlet pipeline, the insect-proof net 44 and the electric air valve 43 are sequentially arranged from outside to inside so as to avoid rainwater, mosquitoes or dust entering the equipment along with fresh air as much as possible, the opening degree of the electric air valve 43 can be adjusted as required to adjust the air inlet quantity, thereby ensuring the cleaning in the equipment and prolonging the service life of related parts.
Further, in order to improve the cleanliness of the fresh air entering the room, the humidity adjusting component further comprises a fresh air filter 13, wherein the fresh air filter 13 is arranged on a fresh air passage between the first heat exchanger 1 and the fresh air supply opening 3, namely, when the fresh air is cooled to a dehumidification temperature through the first heat exchanger 1, the fresh air flows through the fresh air filter 13, after harmful substances such as fine particles are filtered out of the fresh air filter 13, the fresh air enters the room through the fresh air supply opening 3, so that the indoor fresh air cleanliness is improved.
In the above specific embodiment, the temperature adjusting component provided by the invention comprises a second heat exchanger 5, a main fan 6 and an indoor self-circulation air supply outlet 7 communicated with the second heat exchanger 5 through a second air duct; the air inlet side of the second heat exchanger 5 is communicated with the indoor air return port 8, and the refrigerant inlet of the second heat exchanger is communicated with the second refrigerant part 9 through a refrigerant pipeline. In the working process, the main fan 6 sucks indoor hot air into the air conditioner, and the air is cooled by the second heat exchanger 5 and then blown into the room through the indoor self-circulation air supply outlet 7. The first refrigerant component 2 and the second refrigerant component 9 are independently arranged, that is, the first refrigerant component 2 does not interfere with or affect the operation of the second refrigerant component 9 when providing the refrigerant for the humidity adjusting component, and vice versa.
Specifically, the first refrigerant part 2 includes a first condenser, a first compressor, and related piping, and the second refrigerant part 9 includes a second compressor, a second condenser, and related piping.
Besides the structure that the first refrigerant component corresponds to the first heat exchanger and the second refrigerant component corresponds to the second heat exchanger, the temperature and humidity adjusting device provided by the invention can also act on the two heat exchangers through the same set of refrigerant components. Specifically, a refrigerant liquid supply pipe of a compressor is divided into two branches, a throttling device is respectively arranged on each branch for adjusting the throttled evaporation pressure (different evaporation pressures correspond to different evaporation temperatures, namely, high-temperature and low-temperature refrigeration temperatures can be obtained), then the two branches are respectively connected with a first heat exchanger and a second heat exchanger, and the two branches are converged to the compressor after heat exchange, and because the evaporation pressures are different, an evaporation pressure adjusting valve is needed to be arranged on one branch with higher pressure so as to balance the pressures of the two branches.
In the heat exchange process, air around the heat exchanger can be liquefied, the liquefied air forms small liquid drops, and in order to prevent the small liquid drops from flowing into electric elements and ensure the use safety and the service life of equipment, a first water receiving tank 10 is further arranged below the first heat exchanger 1, and the first water receiving tank 10 is communicated with a drain pipe of the air conditioner; and/or, a second water receiving tank 11 is further arranged below the second heat exchanger 5, and the second water receiving tank 11 is communicated with a drain pipe of the air conditioner. In theory, it is the best to provide the first water receiving tank 10 below the first heat exchanger 1 and the second water receiving tank 11 below the second heat exchanger 5, but it is also within the scope of the present invention to provide the first water receiving tank 10 only below the first heat exchanger 1 or the second water receiving tank 11 only below the second heat exchanger 5.
Because humidity control and temperature regulation are independently carried out, in order to avoid mixing between fresh air for humidity control and return air for temperature control, guarantee that two are adjusted smoothly, this temperature and humidity control device still includes baffle 12, first wind channel with the second wind channel passes through baffle 12 separates. The first air duct refers to a fresh air travelling path, the second air duct refers to a return air travelling path, and the first air duct and the second air duct are both fluid travelling tracks or ranges and are not limited in physical structure.
Further, the temperature adjusting component further comprises a self-circulation filter 14, the self-circulation filter 14 is arranged on a return air channel between the air inlet side of the second heat exchanger 5 and the indoor return air inlet 8, and return air entering through the indoor return air inlet 8 is filtered by the self-circulation filter 14 and then enters the air inlet side of the second heat exchanger 5, so that the purity of the return air is improved.
When the target gas is not out of standard, the indoor air can be directly introduced into the first heat exchanger to perform humidity adjustment. To achieve this, at least two methods may be employed, one of which is to provide a bypass valve on the partition 12, the bypass valve being located before the first heat exchanger; secondly, the fresh air fan is positioned indoors, and a bypass valve is arranged in front of the inlet of the fan, so that indoor return air can be introduced.
In addition to the above temperature and humidity adjusting device, the present invention further provides an air conditioner including the above temperature and humidity adjusting device, the air conditioner further includes an indoor unit 101 and an outdoor unit 102, wherein a humidity adjusting component and the temperature adjusting component are disposed in a cabinet of the indoor unit 101, and a fresh air pipe joint 42 of the fresh air generating component is disposed at a side of the cabinet of the indoor unit 101, specifically at a side of the cabinet facing the outdoor unit 102, so as to facilitate pipe distribution; the fresh air supply port 3 in the humidity adjusting part is disposed at the top of the cabinet of the indoor unit 101 or toward the lateral upper part of the indoor side, and the indoor return port 8 in the temperature adjusting part is disposed at the lateral lower part of the cabinet of the indoor unit 101, and the indoor self-circulation supply port 7 is disposed at the lateral upper part of the cabinet of the indoor unit 101, preferably below the fresh air supply port 3.
The first refrigerant component 2 and the second refrigerant component 9 are disposed in the cabinet of the outdoor unit 102, specifically, the first compressor, the first condenser, the second compressor and the second condenser are disposed in the cabinet of the outdoor unit 102; the cabinet of the outdoor unit 102 further includes necessary components for implementing basic functions of an air conditioner, such as the main fan 6, which are the same as those in the prior art, and will not be described in detail.
The fresh air generating assembly may be disposed in the cabinet of the indoor unit 101 or the cabinet of the outdoor unit 102, or may be disposed at an upper portion of the cabinet of the indoor unit 101 or an upper portion of the cabinet of the outdoor unit 102 by another mounting sled.
Besides the air conditioner and the temperature and humidity adjusting device, the invention also provides a temperature and humidity adjusting control system for controlling the temperature and humidity adjusting device.
Referring to fig. 3, fig. 3 is a system block diagram of an embodiment of a temperature and humidity adjustment control system provided by the present invention.
In one embodiment, the control system includes a first detection, a second detection unit 200, and a control unit 400; wherein the first detecting unit 100 is configured to detect a current indoor humidity and output detected current indoor humidity data, and the first detecting unit 100 may be any type of humidity probe configured to detect and output humidity; the second detecting unit 200 is for detecting a current indoor temperature and outputting the detected current indoor temperature data, and the second detecting unit 200 may be any type of temperature probe for detecting and outputting a temperature; the control unit 400 is configured to receive the current indoor humidity data output by the first detection unit 100 and the current indoor temperature data output by the second detection unit 200, compare the current indoor humidity with a pre-stored preset humidity, and compare the current indoor temperature with the pre-stored preset temperature; if the current indoor humidity is greater than or equal to the preset humidity, the control unit 400 sends an opening instruction to the fresh air fan 41 of the humidity adjusting component; if the current indoor temperature is greater than or equal to the preset temperature, the control unit 400 sends an opening instruction to the main fan 6 of the temperature adjusting component.
The temperature comparison and the instruction of the control unit 400 and the humidity comparison and the instruction of the control unit can be synchronously performed, or the humidity comparison and the instruction output can be preferentially performed according to the set requirement, or the temperature comparison and the instruction output can be preferentially performed.
Further, the control system further includes a third detecting unit 300, the third detecting unit 300 being configured to detect a current indoor target gas concentration and output detected current concentration data; the control unit 400 receives the current concentration data outputted from the third detection unit 300 and compares the current concentration with a pre-stored preset concentration; if the current concentration is greater than or equal to the preset concentration, the control unit 400 sends an opening instruction to the fresh air fan 41. Thus, when the indoor target gas concentration exceeds the standard, the control unit 400 sends an opening instruction to the fresh air fan 41 based on the judgment strategy, so as to control the fresh air fan 41 to be opened, the air conditioner enters a fresh air mode, and outdoor fresh air is utilized to timely filter or dilute indoor harmful gas, so that the indoor air quality is improved. The target gas may be carbon dioxide, or may be other indicator gases, such as carbon monoxide or methane.
In order to improve the intelligence and the adjustment accuracy of the control strategy, the control unit 400 may further comprise a difference comparison module, which may be a computer program embedded in the control unit 400 or a chip enabling the difference comparison.
The difference comparison module may be configured to calculate and obtain at least one of a humidity difference between a current indoor humidity and a preset humidity, a temperature difference between a current indoor temperature and a preset temperature, and a concentration difference between a target gas concentration and a preset concentration.
Preferably, in this embodiment, the difference comparing module calculates and obtains the humidity difference, the temperature difference and the concentration difference, respectively, and the three comparisons and the adjustment may be performed simultaneously or in any possible order, for example, the humidity difference may be detected first, the concentration difference may be detected after the adjustment, and the temperature difference may be detected finally; for another example, the concentration difference may be detected first, the humidity difference may be detected after adjustment, and the temperature difference may be detected synchronously; since the comparison result of the concentration difference and the comparison result of the humidity difference will act on the fresh air fan 41, the two types of comparison results can be compared again to adjust the adjustment target with a larger gear span, or preset priority to adjust the adjustment target with a higher priority.
Taking the specific embodiment as an example, specifically, the difference comparison module calculates a humidity difference between the current indoor humidity and the preset humidity, and compares the humidity difference with a pre-stored preset humidity difference; if the current humidity difference is greater than the preset humidity difference, the control unit 400 sends an upshift command to the fresh air fan 41, and if the current humidity difference is less than the preset humidity difference, the control unit 400 sends a downshift command to the fresh air fan 41. In the working process, after the fresh air fan 41 is started, the gear of the fresh air fan 41 is adjusted according to the humidity difference between the current indoor humidity and the preset humidity by comparing the difference; if the current humidity difference is larger than the preset humidity difference, the humidity difference is larger, the gear of the fresh air fan 41 needs to be adjusted to accelerate dehumidification, and if the current humidity difference is smaller than the preset humidity difference, the humidity difference is smaller, and at the moment, the gear of the fresh air fan 41 can be reduced to save energy; thus, when the humidity difference is different, the gear of the fresh air fan 41 can be adjusted at any time so as to ensure the dehumidification effect and efficiency, and simultaneously, the energy consumption is reduced to realize energy conservation.
Meanwhile, a difference comparison module calculates a temperature difference between the current indoor temperature and a preset temperature, and compares the temperature difference with a pre-stored preset temperature difference; if the current temperature difference is greater than the preset temperature difference, the control unit 400 sends an upshift command to the main fan 6, and if the current temperature difference is less than the preset temperature difference, the control unit 400 sends a downshift command to the main fan 6; in the working process, after the fresh air fan 41 is started, the gear of the main fan 6 is adjusted according to the temperature difference between the current indoor temperature and the preset temperature by difference comparison; if the current temperature difference is larger than the preset temperature difference, the temperature difference is larger, the gear of the main fan 6 needs to be adjusted to accelerate temperature adjustment, and if the current temperature difference is smaller than the preset temperature difference, the temperature difference is smaller, and the gear of the main fan 6 can be reduced to save energy; therefore, when the temperature difference values are different, the gear of the main fan 6 can be adjusted at any time, so that the temperature adjusting effect and the efficiency are ensured, and the energy consumption is reduced to realize energy conservation.
Further, the difference comparison module calculates a concentration difference between the current indoor target gas concentration and a preset concentration, and compares the concentration difference with a pre-stored preset concentration difference; if the current concentration difference is greater than the preset concentration difference, the control unit 400 sends an upshift command to the fresh air fan 41, and if the current concentration difference is less than the preset concentration difference, the control unit 400 sends a downshift command to the fresh air fan 41. At this time, if an upshift or downshift instruction has been issued to the fresh air fan 41 after the humidity difference comparison, it is determined that the shift difference between the upshift or downshift twice is large.
It should be appreciated that the difference comparison module is a difference obtained at a set time interval (e.g., a one minute interval, a three minute interval, or other suitable time interval), and the adjustment of the up-down shift is based on the change amount of the difference in unit time.

It should be understood that the above solution is only two embodiments, and not limited to the scope of the present invention, and more similar or similar embodiments are possible under the same concept of the present invention, for example, the quality control of fresh air may not be performed, but only the indoor humidity and the indoor temperature may be detected, and other embodiments are not listed herein.
It should be noted that, the high temperature working mode refers to the working condition that the evaporating temperature exceeds the preset value range, the common working condition refers to the working condition that the evaporating temperature is within the preset value range, and the names of the working conditions are only for convenience of description and do not represent the real working condition of the air conditioner. In the actual working process, the evaporating temperature range corresponds to a low-temperature unit or an ultra-low-temperature unit, for example, the evaporating temperature under the common working condition can be 0-8 ℃, and the evaporating temperature under the high-temperature working condition can be 15 ℃ or other temperature values higher than the evaporating temperature under the common working condition.

The air conditioner, the temperature and humidity adjusting device, the temperature and humidity adjusting control system and the temperature and humidity adjusting control method can achieve the purposes of saving energy and improving comfort level, and specific technical effects can be better verified through the following test data and theoretical analysis.
Specifically, taking a common living room as an example in terms of energy conservation and energy consumption reduction, the cold load of the room in summer comprises two parts, (1) the cold load formed by the heat obtained by the enclosure structure; and (2) a cooling load formed by a heat source and a humidity source in the room.
Taking the case of the indoor temperature of 26 ℃ and the relative humidity of 60% as an example, the cold load of the enclosure structure of 2881W, the indoor heat source does not consider the heat generation of indoor electric equipment, only the sensible heat of 61W, the latent heat of 73W and the moisture dissipation of 109g/h under the condition of the light labor load of three adult men in the environment of the designed temperature of 26 ℃, at the moment, the sensible heat load of 3064W, the latent heat load of 219W, the total heat load of 3264W, the wet load of 327g/h (without considering other open water moisture dissipation) of the room are taken into account, and the indoor air enthalpy value of h1= 58.37kJ/kg. Assuming that the outdoor temperature in summer is 33 ℃ and the relative humidity is 80%, the maximum fresh air volume is 120m 3/h=0.033 m 3/s=0.04 kg/s (unit conversion) of the outdoor air, the enthalpy value of the outdoor air is h2= 99.16kJ/kg, the maximum fresh air load Q=0.04X (h 2-h 1) X1000=1634W, and the total load of a room after fresh air is introduced is 3264+1634= 4898W.
Under the traditional temperature and humidity combined regulation working condition, a common working condition compressor is adopted, the evaporation temperature t0=4 ℃, the condensation temperature tk=40 ℃, the theoretical refrigeration coefficient of R134a is 6.315 by taking R134a as an example, and the theoretical power consumption of the compressor is 4898/6.315 = 775.6W.
Under the independent temperature and humidity regulation working condition, a common working condition compressor is adopted to bear indoor fresh air and latent heat load, and a high temperature working condition compressor is adopted to bear indoor sensible heat load, wherein the evaporation temperature t0=4 ℃, the condensation temperature tk=40 ℃ of the common working condition compressor, the evaporation temperature t0=15 ℃ of the high temperature working condition compressor and the condensation temperature tk=40 ℃.
The outdoor fresh air is cooled and dehumidified by the refrigeration under the common working condition and then is sent into a room, the heat exchange temperature difference of 6 ℃ is considered, the state point after the fresh air treatment is 10 ℃, the relative humidity is 95%, h3=28.31 kJ/kg, the fresh air load is Q=Q=0.04X (h 2-h 3) X1000=2834W, and the theoretical power consumption is 2834/6.315 = 448.8W. The remaining 4898-2834=2064w load is borne by the high temperature operating compressor, and the calculated parameters are shown in table one:
