Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As shown in fig. 1 to 10, a preferred embodiment of the present invention is shown, wherein, for the convenience of viewing the internal components of the fresh air conditioner, the fresh air conditioner in fig. 1, 2 and 4 has a cover plate removed from the casing. The arrows in the circulation lines in fig. 7 to 10 indicate the flow direction of the refrigerant, and the crosses in the circulation lines indicate that no refrigerant flows in the lines.
The fresh air conditioner in the present embodiment includes a total heat exchanger 200, a first heat exchanger 110, a second heat exchanger 120, and a controller (not shown in the figure). The total heat exchanger 200 has an indoor air inlet 210, an outdoor air inlet 230, an indoor air outlet 220, and an outdoor air outlet 240, wherein indoor air enters the total heat exchanger 200 through the indoor air inlet 210 and is then discharged to the outside through the outdoor air outlet 240, and outdoor air enters the total heat exchanger 200 through the outdoor air inlet 230 and is then discharged to the inside through the indoor air outlet 220. The indoor air and the outdoor air are simultaneously introduced into the total heat exchanger 200, and the two air streams have respective air flow paths in the total heat exchanger 200, are not mutually merged, and are respectively led out of the total heat exchanger 200 after only heat exchange.
The first heat exchanger 110 is configured to exchange heat with the airflow guided out from the indoor air outlet 220, and may specifically be tightly attached to the indoor air outlet 220 of the total heat exchanger 200, so that the outdoor air guided out from the total heat exchanger 200 exchanges heat with the first heat exchanger 110 and is guided into the room. The second heat exchanger 120 is configured to exchange heat with the airflow guided out by the outdoor air outlet 240, and may specifically be tightly attached to the outdoor air outlet 240 of the total heat exchanger 200, so that the indoor air guided out by the total heat exchanger 200 is guided to the outside after exchanging heat with the second heat exchanger 120.
The controller is configured to control the operation states of the first heat exchanger 110 and the second heat exchanger 120 according to the operation mode of the fresh air conditioner, wherein the operation states comprise opening, closing, heat absorption or heat release of the first heat exchanger 110 and the second heat exchanger 120. That is, in different operation modes, the controller controls the first heat exchanger 110 and the second heat exchanger 120 to be opened and closed, and controls the heat releasing or absorbing state of the first heat exchanger 110 at the same time, and it is noted that the fresh air conditioner may have only the above two heat exchangers, and may also have other heat exchangers, so that the first heat exchanger 110 and the second heat exchanger 120 may absorb heat at the same time, and may also release heat at the same time. And the control of the working state of absorbing or releasing heat can be realized by controlling the flow direction of the refrigerant in the circulating line.
As shown in fig. 10, when the fresh air conditioner has the fresh air exchange function, the controller controls the first heat exchanger 110 and the second heat exchanger 120 to be closed, at this time, outdoor air enters the total heat exchanger 200 to be filtered, exchanges heat with air entering the total heat exchanger 200 from the indoor and then is introduced into the indoor, and indoor air entering the total heat exchanger 200 exchanges heat and then is led out to the outdoor, thereby realizing the fresh air exchange function. Specifically, the fresh air conditioner may include a blower fan which blows air to the outside or to the inside, and when blowing air to the outside, negative pressure is formed in the inside, and the outdoor air is sucked into the inside to exchange fresh air. When the air is blown into the room, positive pressure is formed in the room, and the indoor air is sucked out of the room. In order to improve the efficiency of air circulation, in one embodiment, the fresh air conditioner includes a first fan 410 and a second fan 420, the first fan 410 is configured to guide the indoor air to the outside through the indoor intake port 210 and the outdoor outlet port 240 of the total heat exchanger 200, and the second fan 420 is configured to guide the outdoor air to the inside through the outdoor intake port 230 and the indoor outlet port 220 of the total heat exchanger 200. The two fans are arranged, so that the flow rates of the indoor air and the outdoor air in the total heat exchanger 200 are more synchronous, and the heat exchange effect can be enhanced.
As shown in fig. 7, when the operation mode of the fresh air conditioner is the cooling mode, the controller controls the first heat exchanger 110 to start and absorb heat, and at this time, the first heat exchanger 110 serves as an evaporator. The controller controls the second heat exchanger 120 to turn on and release heat, when the second heat exchanger 120 acts as a condenser. Outdoor air is sucked into the fresh air conditioner by the second fan 420, passes through the total heat exchanger 200 and exchanges heat with indoor air sucked in the total heat exchanger 200, and because the indoor air has a relatively low temperature, the outdoor air in the total heat exchanger 200 can transfer heat to the indoor air in the total heat exchanger 200, so that the outdoor air in the total heat exchanger 200 is cooled for the first time. The indoor air discharged from the total heat exchanger 200 is introduced into the room after being cooled down for the second time by the first heat exchanger 110. The indoor air is sucked into the fresh air conditioner by the first fan 410, passes through the total heat exchanger 200 and exchanges heat with the outdoor air in the total heat exchanger 200, so that the heat of the indoor air rises to a certain extent, but the temperature of the indoor air in the total heat exchanger 200 is lower than that of the outdoor air, the indoor air in the total heat exchanger 200 is led out by the outdoor air outlet 240 and exchanges heat with the second heat exchanger 120, and the led-out indoor air has lower temperature, so that the heat exchange efficiency between the indoor air and the second heat exchanger 120 is higher.
In the above working process, the fresh air conditioner has the refrigeration function and performs fresh air exchange in the refrigeration process, and although the indoor low-temperature air is led out to the outdoor in the fresh air exchange process, the indoor air with lower temperature exchanges heat with the air to be led into the indoor and exchanges heat with the second heat exchanger 120 serving as a condenser, so that the energy contained in the indoor air is well utilized, energy waste is not caused, and the refrigeration and fresh air exchange processes are performed simultaneously, so that energy is saved.
The working process of exchanging fresh air while refrigerating is only disclosed, and certainly, the working process can also be the same as the refrigerating mode of a conventional air conditioner, indoor air is sucked into the first heat exchanger 110 for heat exchange and then is led into the room during refrigerating, and outdoor air is led out of the room after heat exchange with the second heat exchanger 120.
In one embodiment, the fresh air conditioner further includes a third heat exchanger 130, the third heat exchanger 130 is configured to exchange heat with outdoor air before the outdoor air enters the outdoor air inlet 230, and the operation state of the third heat exchanger 130 is controlled by the controller, that is, the on/off state and the heat absorption/release state of the third heat exchanger 130 are controlled by the controller.
As shown in fig. 8, the addition of the third heat exchanger 130 can enable the fresh air conditioner to have a better dehumidification function, when the working mode of the fresh air conditioner is a cooling dehumidification mode, the controller controls the first heat exchanger 110 to be closed, controls the second heat exchanger 120 to be opened and release heat (at this time, the second heat exchanger 120 serves as a condenser), and controls the third heat exchanger 130 to be opened and absorb heat (at this time, the third heat exchanger 130 serves as an evaporator). When the cooling and dehumidifying mode is used, the power of the third heat exchanger 130 can be increased to lower the temperature, so that the temperature difference between the outdoor air and the third heat exchanger 130 is larger and the water vapor is more condensed than the first heat exchanger 110 in the cooling mode, so that the humidity of the outdoor air to be introduced into the room is lower. However, since the outdoor air is subjected to heat exchange with the indoor air of the total heat exchanger 200 after heat exchange with the third heat exchanger 130, and since the outdoor air is subjected to temperature reduction once, the temperature difference between the indoor air and the outdoor air in the total heat exchanger 200 is large, the heat exchange efficiency of the indoor air and the outdoor air is high, so that the temperature of the outdoor air introduced into the room from the total heat exchanger 200 is increased to a certain extent, the final temperature of the outdoor air introduced into the room from the total heat exchanger 200 is not lower due to the increase of the power of the third heat exchanger 130, and only the humidity is reduced, so that the user experience is better.
For example, in the conventional cooling and dehumidifying mode, the temperature of the evaporator is lowered to 18 degrees, and the temperature of the air blown into the room by the air conditioner is maintained substantially at about 18 degrees (actually, it may be slightly higher than 18 degrees). In this embodiment, the temperature of the third heat exchanger 130 is decreased to 14 degrees, and the temperature of the air after heat exchange by the third heat exchanger 130 is substantially maintained at about 14 degrees, compared with the conventional mode, the humidity of the air after heat exchange by the third heat exchanger 130 is lower, the outdoor air exchanges heat with the indoor air in the total heat exchanger after heat exchange by the third heat exchanger, and the temperature is increased to substantially maintain at 18 degrees, and then the outdoor air is blown into the room.
In the cooling and dehumidifying mode, the temperature of the indoor air discharged from the total heat exchanger 200 is lower than that of the outdoor air, so that the heat exchange efficiency between the discharged indoor air and the second heat exchanger 120 is higher, and the energy consumption of the second heat exchanger 120 is smaller.
As shown in fig. 9, when the operation mode of the fresh air conditioner is the heating mode, the controller controls the first heat exchanger 110 to be turned on and release heat, and at this time, the first heat exchanger 110 serves as a condenser. The controller controls the second heat exchanger 120 to turn on and absorb heat, when the second heat exchanger 120 acts as an evaporator. The controller controls the third heat exchanger 130 to turn on and release heat, when the third heat exchanger 130 is acting as a condenser. The outdoor air is introduced into the total heat exchanger 200 after exchanging heat with the third heat exchanger 130, and the temperature of the outdoor air in the total heat exchanger 200 is increased, because the indoor air in the total heat exchanger 200 has a high temperature, the outdoor air in the total heat exchanger 200 can exchange heat for the second time, so that the temperature of the outdoor air is further increased, and the outdoor air in the total heat exchanger 200 is introduced out of the total heat exchanger 200, and then introduced into the room after exchanging heat for the third time with the first heat exchanger 110. Like the summer refrigeration mode, the fresh air conditioner in the embodiment can well utilize the heat in the indoor air, so that the fresh air conditioner has a certain energy-saving effect compared with a product which can exchange fresh air and has air conditioning capacity in the prior art.
As shown in fig. 7 to 10, in the circulation pipeline of the fresh air conditioner, the first heat exchanger 110 is connected in parallel with the third heat exchanger 130, and both the first heat exchanger 110 and the third heat exchanger 130 are connected in series with the second heat exchanger 120, so that the controller can conveniently achieve the control effect.
In an embodiment, the compressor 300 for compressing the refrigerant in the fresh air conditioner can dissipate heat by using the first fan 410, that is, as shown in fig. 2, indoor air or outdoor air (which air can be determined according to the temperature of the indoor air and the outdoor air, and the air flow with lower temperature can be selected to dissipate heat of the compressor 300) blows to the compressor 300 and then is extracted to the outside by the first fan 410, so as to dissipate heat of the compressor 300.
The fresh air conditioner in this embodiment further includes a housing 500, and the housing 500 defines an accommodation chamber. The compressor 300, the total heat exchanger 200, the first fan 410, the second fan 420, the first heat exchanger 110, the second heat exchanger 120 and the third heat exchanger 130 are uniformly arranged in the accommodating cavity, the housing 500 is provided with a first air inlet 510, a first air outlet 520, a second air inlet 530 and a second air outlet 540, indoor air enters the accommodating cavity from the first air inlet 510 and is led out to the outside through the second air outlet 540, outdoor air enters the accommodating cavity from the second air inlet 530 and is led out to the inside through the first air outlet 520, a purification net 600 for filtering air is arranged at the first air inlet 510 and/or the second air inlet 530, and the purification net 600 can effectively prevent foreign matters and dust from entering the housing 500.
Specifically, the total heat exchanger 200 may have a hexagonal prism shape as shown in fig. 3, in which a top surface, a bottom surface, and two opposite side surfaces are closed, and the other four surfaces are in conduction. The indoor air inlet 210 is communicated with and arranged opposite to the outdoor air outlet 240, and the outdoor air inlet 230 is communicated with and arranged opposite to the indoor air outlet 220. The indoor air and the outdoor air exchange heat only in the total heat exchanger 200, and they do not mutually merge. Each air outlet and each air inlet of the total heat exchanger 200 may be in a hole shape, or as shown in fig. 3, the whole side surface may be used for air inlet or air outlet.

The second heat exchanger 120 may be closely attached to the outdoor air outlet 240 of the total heat exchanger 200, or may be disposed at an interval from the outdoor air outlet 240. The third heat exchanger 130 may be closely attached to the outdoor air inlet 230 of the total heat exchanger 200, or may be spaced from the outdoor air inlet 230.
In the case 500, the first fan 410 and the second fan 420 are independently divided into two chambers, and the outdoor air outlet 240 of the total heat exchanger 200 is communicated with the chamber where the first fan 410 is located, so that only the indoor air guided out by the outdoor air outlet 240 can be drawn out of the case 500 by the first fan 410. The indoor outlet 220 of the total heat exchanger 200 communicates with the chamber where the second fan 420 is located, so that only the outdoor air guided out of the indoor outlet 220 can be guided out of the case 500 by the second fan 420.
