FIELD OF TECHNOLOGY

The following relates to the air purification field, in particular to an air purifier based on the principle of vapor condensation and adsorption and an air-conditioning apparatus having the air purifier.

BACKGROUND

The human body is surrounded by air, and the quality of air is vital to the comfort and health of the human body, and air that can meet three indicators, i.e. cleanliness, temperature and humidity, is the most suitable for the human body.
Cleanliness refers to the degree of air pollution, and the pollutants in the air contain three phase substances, i.e. the solid substances, the liquid substances and the gas substances; the solid particulate pollutants comprise TSP, PM 10, PM 2.5, etc.; the gas pollutants comprise sulfur dioxide, nitride, ozone, ammonia, formaldehyde, etc.; and if these pollutants are not removed, it will seriously affect the health of the human body.
The humidity of vapor in the air is divided into absolute humidity, saturated humidity and relative humidity. Absolute humidity refers to the amount of vapor actually present in a unit volume of air; saturated humidity refers to the limit amount of vapor that can be present in a unit volume of air under a certain pressure and temperature; relative humidity refers a percentage expression of the ratio of the absolute humidity to the saturated vapor content at the same temperature. Experiments show that when the relative humidity of vapor is 50% to 60%, the human body feels most comfortable and it is not easy to cause diseases. Neither too high nor too low humidity of vapor in the air is good for the health of the human body.
When the air is contaminated, the current method of purifying air in households is mainly to adsorb pollutants with activated carbon; the principle of adsorption is that the porous structure of the activated carbon provides a large surface area so as to present an ability to adsorb and collect impurities; and this method has many disadvantages summarized as follows:
1. The activated carbon has limited adsorption capacity, and after adsorption is saturated, it will lose its ability to purify the air, requiring replacing the activated carbon to continue purifying the air;
2. The saturated activated carbon is discarded and becomes a new pollutant, causing secondary pollution to the environment;
3. The humidity of the air cannot be adjusted;
4. The temperature of the air cannot be adjusted.
On the other hand, the conventional art discloses an indoor pollutant abatement and purification technology (Publication Number 105664653B), which discloses seven steps of abatement and purification, including convecting wind blow and suction are carried out on the air to be purified after cooling, and particles in the air to be purified are easily attached to the condensed vapor and discharged out of a room along with convecting wind, and it can be seen that it must work under the premise of the circulation of the indoor air and outdoor air, and this has at least the following two defects: first, due to the circulation of the indoor air and outdoor air, it is difficult to prevent the outdoor air pollution from merging with the indoor air, causing the indoor air to be re-contaminated, and losing the significance of abating and purifying indoor pollutants; secondly, due to the circulation of the indoor air and outdoor air, the humidity and temperature of the indoor air are constantly affected by the outdoor air, resulting in that it is difficult to effectively adjust the humidity and temperature of the indoor air to the ideal values.

DETAILED DESCRIPTION

In the following, the technical solutions in the implementations and embodiments of the present disclosure are explained clearly and fully, and apparently, the described embodiments are merely a part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by one of ordinary skill in the art without creative work belong to the protective scope of the present disclosure.
An air purifier based on the principle of vapor condensation and adsorption of the present disclosure, carries out three processes, that is humidifying the air, cooling the air and heating the air, when it is needed to purify the air and adjust the temperature and humidity of the air, and an action order of a preferred scheme for these three process is: humidifying the air—cooling the air—heating the air; however, it is obvious that varying the order of humidifying the air, cooling the air and heating the air in a specific embodiment, can also play a role in purifying the air and adjusting the humidity and temperature of the air, which also belongs to the protective scope of the present disclosure. The specific structure of the air purifier comprises the following embodiments:

In one embodiment of the present disclosure, as shown in FIG. 1, the air purifier based on the principle of vapor condensation and adsorption comprises a humidifying device 1, a cooling device 2, a heating device 3, and an air blowing device 4; wherein the humidifying device 1 is used to increase the content of vapor in the air; the cooling device 2 is used to reduce the temperature of the air; the heating device 3 is used to heat the air so as to increase the temperature of the air; the humidifying device 1, the cooling device 2 and the heating device 3 are connected to form a whole via the circulation of the air, specifically, the humidifying device 1, the cooling device 2 and the heating device 3 are sequentially intercommunicated to form a passage for air circulation, an inlet of the humidifying device 1 is an inlet of the passage for air circulation, and an outlet of the heating device 3 is an outlet of the passage for air circulation, and under the action of the air blowing device 4, the air to be purified flows in via the inlet of the passage for air circulation, and when the air is cooled at the cooling device 2, vapor in the air is condensed into droplets and solid particles and adsorbs pollutants in the air during condensation, and the pollutants, together with the droplets and solid particles formed by the condensation of vapor, drip from the air to be purified under the action of gravity, so as to be removed from the air to be purified, and the heating device 3 is used for heating the air, such that the air discharged from the outlet of the passage for air circulation satisfies a pre-set temperature threshold.
In embodiments of the present disclosure, the vapor may be water vapor, and may also be vapor of other liquid solutions, such as brine solution, alkaline aqueous solution or acid aqueous solution, wherein the brine solution can be applied to subzero temperature environment, the alkaline aqueous solution can enhance the purifying capacity for acid gases (such as sulfur dioxide gas), and the acid aqueous solution can enhance the purifying capacity for alkaline gases (such as ammonia gas). In the following, it takes water/vapor as an example to explain:
In the present embodiment of the present disclosure, the humidifying device 1 comprises a liquid reservoir 11, a booster pump 12 and an atomizing nozzle 13, as shown in FIG. 1, the liquid reservoir 11 is used to store water; the booster pump 12 is used to enable the water in the liquid reservoir to flow towards the atomizing nozzle 13 at a pre-set pressure threshold; the atomizing nozzle 13 is used to spray out the water from the booster pump in a mist form; and the liquid reservoir 11, the booster pump 12 and the atomizing nozzle 13 are connected via water pipes.
The cooling device 2 is a refrigerant evaporator 21 in an air conditioning system, and the heating device 3 is an electric heating wire or electric heating wires 31.
In order to facilitate the collection of droplets and solid particles condensed with pollutants, the air purifier is further provided with a collection container for receiving the droplets and solid particles formed by the condensation of vapor, which is disposed at a lower part of the cooling device 2 so as to clean the waste liquid in the collection container by the user after a period of time. Or, the air purifier is further provided with a drain outlet for discharging the droplets and solid particles formed by the condensation of vapor, that is, it does not need the user to regularly clean the container for collecting the waste liquid.
In order to realize the control of the temperature and humidity, the air purifier is further provided with a controller, a temperature sensor and a humidity sensor both electrically connected with the controller, the temperature sensor is used to detect temperature at the outlet of the passage for air circulation, the humidity sensor is used to detect humidity at the humidifying device, and the controller adjusts heating temperature of the heating device according to the detection result of the temperature sensor, and adjusts humidification of the humidifying device according to the detection result of the humidity sensor.
Based on the principle that the higher the temperature, the higher the saturability of the water vapor, that is, the higher the temperature, the more aqueous solution can be evaporated to form water vapor, therefore, a preferred implementation is: the air purifier is further provided with a second heating device (not shown), and the second heating device is provided at the humidifying device 1 to increase the saturated humidity of the vapor at the humidifying device 1, which brings advantages as follow: at high temperature, due to the high saturability of the vapor the air can contain more vapor, that is to say, the vapor in unit volume is denser, so that the vapor can be condensed into more droplets or solid particles under the action of cooling device 2, the droplets or solid particles wrap and adsorb more pollutants, and finally remove more pollutants from the air in unit time, improving the purification efficiency.
Even if a small amount of pollutants is not discharged from the air purifier along with the droplets formed from water vapor, after returning back into the room for a period of time, it will be sucked into the air purifier again by the air blowing device to achieve circulated purification.
Further, as a preferred implementation, the air purifier further comprises an air pollutant detection device connected with the controller, the air pollutant detection device is used to detect pollutant concentration in the air, specifically, the air pollutant detection device may be disposed within the air purifier (to detect the pollutant concentration at the outlet of the air purifier), and may also be disposed outside the air purifier (to detect the indoor pollutant concentration), and if the detection result of the pollutant concentration is unsatisfactory (beyond a concentration threshold), the controller heightens the heating temperature of the second heating device, and preferably, increases the humidification of the humidifying device 1 at the same time; and if the detection result of the pollutant concentration keeps at an ideal level for a period of time, the controller turns off the air purifier, that is, cuts off the power supply of the humidifying device 1, the cooling device 2 and the heating device 3, referring to the positive (+) and negative (−) symbols in FIG. 1 for the power supply. It may utilize a particulate matter concentration detection device to detect the pollutant concentration in the air.
The operating principle of the air purifier based on the principle of vapor condensation and adsorption provided in the present disclosure is as follow:
When the air contains pollutants such as fog and haze, nitrides, sulfides, and formaldehyde and needs to be purified, the air driven by natural wind or the air blowing device 4 can be blown to flow through the humidifying device 1, the cooling device 2 and the heating device 3; when the air humidity is low, the humidifying device is turned on to spray water mist into the air to increase the moisture (water vapor) content in the air, and specifically: the booster pump 12 is turned on to enable the water in the liquid reservoir 11 to flow towards the atomizing nozzle 13; the atomizing nozzle 13 sprays water from the booster pump 12 into the air in a mist form, to increase the water content in the air; when the air flows through the cooling device 2, the air and the cooling device 2 perform heat exchange, and specifically: the air conditioning system 23 is started, the refrigerant evaporator 21 in the air conditioning system decreases the temperature due to the evaporation of the refrigerant, and when air flows through the surface of the refrigerant evaporator 21 in the air conditioning system, the air and the refrigerant evaporator 21 in the air conditioning system perform heat exchange, and the temperature of the air is reduced by the low-temperature refrigerant evaporator 21 in the air conditioning system, and when the temperature of the vapor is lower than the dew point temperature or the solidification temperature under this condition, the vapor in the air begins to get liquefied and solidified, and gradually becomes tiny water droplets and ice particles floating in the air, the collision between small water droplets or between small water droplets and small ice particles further forms large water droplets and ice particles, and the water droplets and ice particles continue to merge in the floating movement, so that the water droplets and/or ice particles continue to enlarge, and when the water droplet and ice particle enlarges until its gravity can overcome the support of the air, it will drip from the air; when the air is cooled by the cooling device 2 (the refrigerant evaporator 21 in the air conditioning system), and the water vapor in the air condenses into water droplets and ice particles due to the cooling, the tiny solid particulate pollutants in the air can just play the role of nucleus of condensation, which not only accelerates the condensation of water vapor, but also causes the tiny solid particulate pollutants to be wrapped in water droplets and ice particles, and can be removed from the air along with the separation of the water droplets and ice particles from the air; on the other hand, when the water vapor in the air condenses into water droplets and ice particles, the sum of the surface areas will be very huge due to the large number of small water droplets and ice particles; such huge large surface areas can sufficiently adsorb various pollutants in the air, so as to further purify the air, especially for water-soluble pollutants such as nitrides, sulfides, and formaldehyde, which will be completely removed from the air once being wrapped or adsorbed by water droplets and dissolved in the water; the humidification effect of the humidifying device 1 and the cooling effect of the cooling device 2 jointly complete the first step: the purification effect of the air; the moisture in the air is also reduced during the process of vapor condensation and separation from the air, in this way, the cooling effect of the cooling device 2 (the refrigerant evaporator 21 in the air conditioning system) completes the second step of air humidity adjustment while completing the air purification: reducing the air humidity, and avoiding the humidification process to produce a too high air humidity to cause discomfort to the human body or fail to meet specific humidity requirements; after the air flows through the cooling device 2 and is cooled, if the temperature is lower than the temperature at which the human body feels comfortable or a specific required temperature, the heating device 3 is turned on (turning on the power supply of the electric heating wire(s) 31), the electric heating wire(s) 31 starts to generate heat under the action of current, and the air is heated when it flows through the electric heating wire(s) 31, and its temperature increases until the temperature rises to the temperature that the human body feels comfortable or to a specific required temperature; after the air temperature rises, the saturation humidity of the air increases with it, and the absolute humidity of the air remains constant during this process, so that the relative humidity of the air decreases as the air temperature increases until the air reaches the relative humidity which is suitable for the human body or a specific required relative humidity, which completes the third step of air humidity adjustment: relative humidity adjustment; the foregoing three steps achieve the triple function, i.e., the purification treatment and temperature and humidity adjustment of polluted air, and the polluted air purified by air purifier based on the principle of vapor condensation and adsorption can simultaneously meet the requirements of human body for air cleanliness, humidity and temperature.

Embodiment 2

The difference from Embodiment 1 is that in this embodiment of the present disclosure, the order of connection between the humidifying device 1, the cooling device 2 and the heating device 3 has changed: as shown in FIG. 2, the cooling device 2, the humidifying device 1 and the heating device 3 are connected sequentially, and the cooling device 2 is close to the inlet of the passage for air circulation (that is, the inlet of the cooling device 2 is the inlet of the passage for air circulation, and is connected to the air blowing device 4), and the heating device 3 is close to the outlet of the passage for air circulation (that is, the outlet of the heating device 3 is the outlet of the passage for air circulation).

Embodiment 3

The difference from Embodiment 1 and Embodiment 2 is that in this embodiment of the present disclosure, the order of connection between the humidifying device 1, the cooling device 2 and the heating device 3 has changed: as shown in FIG. 3, the heating device 3, the humidifying device 1 and the cooling device 2 are connected sequentially, and the heating device 3 is close to the inlet of the passage for air circulation (that is, the inlet of the heating device 3 is the inlet of the passage for air circulation, and is connected to the air blowing device 4), and the cooling device 2 is close to the outlet of the passage for air circulation (that is, the outlet of the cooling device 2 is the outlet of the passage for air circulation).
Both Embodiment 2 and Embodiment 3 are adjusted based on Embodiment 1 in the order of connection between the humidifying device 1, the cooling device 2 and the heating device 3, but the principle of achieving air purification is the same as that of Embodiment 1.

Embodiment 4

In another optional embodiment of the present disclosure, the humidifying device 1 comprises a liquid reservoir, an ultrasonic generator and an oscillating piece; wherein the oscillating piece is set in the liquid reservoir, and the ultrasonic generator is used to provide a high oscillation frequency to the oscillating piece so as to atomize the liquid in the liquid reservoir into vapor.
In the current embodiment, it further provides another applicable scheme of the cooling device 2, as shown in FIG. 4, the cooling device 2 is a cold air duct 26 through which the natural cold air passes.
When the natural cold air is easier to be obtained and the temperature of the polluted air is higher, for example, the temperature of outdoor air in winter is generally lower, and the polluted air is indoor air and has a higher temperature; the natural cold air is blown into the natural cold air duct 26 by a natural cold air blowing device 25, which is made of a material with good thermal conductivity, and when the polluted air flows along a polluted air duct 24 to contact the outer surface of the natural cold air duct 26, the polluted air indirectly exchanges heat with the natural cold air via the outer wall of the low-temperature natural cold air duct 26, thereby achieving the cooling effect of the cooling device 2.
In the current embodiment, another possible implementation of the heating device 3 is further provided, and referring to FIG. 5, the heating device 3 is a refrigerant condenser 32 in an air conditioning system, and the refrigerant condenser 32 in the air conditioning system is connected to the refrigerant evaporator 21 in the air conditioning system via the refrigerant pipe(s) 22 of the air conditioning system, and it should be noted that the refrigerant condenser 32 is different from that in the normal use situation, that is, the above-mentioned refrigerant condenser 32 is set indoors or in a space to be air-purified. When the air conditioning system is in operation, the compressor sucks in the low-temperature and low-pressure gaseous refrigerant from the refrigerant evaporator 21 in the air conditioning system and compresses the refrigerant, and therefore due to work, the temperature and pressure of the refrigerant are changed into a high temperature state, and the refrigerant is then sent into the refrigerant condenser 32 in the air conditioning system, due to the heat exchange effect, the surface temperature of the refrigerant condenser 32 in the air conditioning system is heated up by the high temperature refrigerant, and when the air cooled by the cooling device 2 flows through the surface of the refrigerant condenser 32 in the air conditioning system, it is heated by the refrigerant condenser 32 in the air conditioning system, the heating effect of the heating device 3 is realized; at the same time, the temperature of the refrigerant itself is reduced to get liquefied to become liquid. The advantage of the current embodiment is that it takes advantage of the characteristics of that the refrigerant needs to reduce the heat by heat emission, it heats the air with the heat emitted by the refrigerant to effectively use the waste heat, and to save energy; and meanwhile, the low-temperature cold air is more beneficial to the heat emission of the refrigerant, and reduces the energy consumption of the air-conditioning compressor, which further saves the energy; especially when the cooling device 2 is a refrigerant evaporator 21 in an air conditioning system, the energy-saving effect is particularly obvious.
It should be understood that the variable embodiments of the humidifying device 1, the cooling device 2 and the heating device 3 in the current embodiment may be partially or wholly introduced into Embodiment 1, Embodiment 2 or Embodiment 3 to replace the implementations of the humidifying device 1, the cooling device 2 and the heating device 3 in the original embodiments, and the new embodiments obtained by simple combination should also fall into the protection scope claimed by the present disclosure.

Embodiment 5

In one embodiment of the present disclosure, a new-type air conditioner combining the above-mentioned air purifier function is provided, and compared with the air conditioner in the conventional art, the difference is that it includes two or more condensers, at least one condenser is installed indoors as a heating device of the air purifier, and an evaporator of the new-type air conditioner is still installed indoors and used as a cooling device of the air purifier.
It works as follows:
Under the control of the control device, it is divided into three working modes: pure cooling mode, pure air purification mode, and cooling and air purification combined mode.
In the pure cooling mode, under the function of the control device, the refrigerant does not flow through the condenser disposed indoors, and the condenser disposed indoors does not work, and in this working mode, the new-type air conditioner refrigerates the indoor air in accordance with the working process of the air conditioner in the conventional art. The advantage of this working mode is that when the cleanliness of indoor air reaches the threshold, the new-type air conditioner turns off the air purification function, which is conducive to energy conservation;
When working in the pure air purification mode, under the action of the control device, the refrigerant does not flow through the condenser disposed outdoors, the refrigerant only releases heat in the condenser disposed indoors, and heats the air to be purified while releasing the heat, which functions as a heating device in the air purifier; at the same time, the refrigerant evaporates and absorbs heat when it flows to an evaporator disposed indoors, and reduces the temperature of the air to be purified flowing through the evaporator, and functions as the cooling device in the air purifier. The advantage of this working mode is that when the new-type air conditioner activates the air purification function, the heat absorbed by the indoor air to be purified is theoretically equal to the heat released to the indoor air to be purified, it generally does not affect the temperature of the indoor air, avoids to affect the temperature of the indoor air when the air purification function is activated and avoids the situation of adding additional equipment and consuming additional power to eliminate this effect, which is beneficial to saving equipment costs and energy.
When working in the cooling and air purification combined mode, the position where the refrigerant releases heat is proportionally distributed by the control device to the outdoor condenser and the indoor condenser, corresponding to the outdoor release of heat and the indoor release of heat, respectively, and for the heat released outdoors, the heat is transferred from the indoor air to the outside, which generally has a cooling effect on the indoor air and plays the role of cooling of the traditional air conditioner, and the heat released indoors by the refrigerant heats the air to be purified flowing through the indoor condenser and plays the role of the heating device in the air purifier. The advantage of this working mode is that the effect of the new-type air conditioner on the indoor air temperature when the air purification function is activated, under the function of the control device, works towards an advantageous direction, and the dual functions of indoor air purification and temperature regulation is achieved with the most simplified equipment and the lowest energy consumption.
In the current embodiment of the air conditioner, the refrigerant flows to the outdoor condenser or the indoor condenser or is distributed to the outdoor condenser and the indoor condenser according to a pre-set ratio, and the flow direction control can be realized through a reversing valve (not shown), which is a commonly used reversing device in air-conditioning equipment, and will not be repeated here.

Any equivalent structure or equivalent process transformation utilizing the content of the specification and drawings of the present disclosure, or applying the content of the specification and drawings of the present disclosure in the other related technical fields directly or indirectly, should be covered by the protective scope of the present disclosure.

For the sake of clarity, it is to be understood that the use of ‘a’ or ‘an’ throughout this application does not exclude a plurality, and ‘comprising’ does not exclude other steps or elements.
