Detailed Description

The air conditioning system and the compressor and exhaust structure thereof according to the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

As used in this specification, the singular forms "a," "an," and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification, the term "or" is generally employed in its sense including "and/or" unless the content clearly dictates otherwise.

In the present embodiment, there is first provided an air conditioning system including two condensers. As shown in fig. 1, the air conditioning system further includes a compressor 10, where the compressor 10 includes a housing 11, and a first cylinder and a second cylinder disposed in the housing 11, the first cylinder may be specifically one of an upper cylinder 12 and a lower cylinder 13, and the second cylinder may be the other of the upper cylinder 12 and the lower cylinder 13, where the upper cylinder 12 is close to the motor 14, and the lower cylinder 13 is far from the motor 14.

Fig. 1 is a schematic structural diagram of a compressor according to an embodiment of the present invention, in which arrows indicate a flow direction of gas, and as shown in fig. 1, when the compressor 10 is vertically installed with respect to a horizontal plane, the upper cylinder 12 and the lower cylinder 13 are arranged up and down, a middle partition 15 is disposed between the two cylinders, and a discharge chamber 151 is disposed in the middle partition 15. Here, the upper and lower positions of the upper cylinder 12 and the lower cylinder 13 are not fixed and may be changed according to the installation direction of the compressor 10, for example, when the compressor 10 is installed horizontally with respect to a horizontal plane, the two cylinders are horizontally arranged, or when the compressor 10 is installed obliquely with respect to the horizontal plane, the two cylinders are correspondingly obliquely arranged. Therefore, the terms "up" and "down" are not used herein to limit the relative positions of the two cylinders in the present invention.

Further, the compressor 10 further includes an exhaust structure, and the exhaust structure includes a muffler, a middle partition 15 and two exhaust ports, the two exhaust ports are disposed on the housing 11, and one of the muffler may be an upper muffler or a lower muffler.

Specifically, an upper head 121 is mounted on the upper end surface of the upper cylinder 12, and the upper end surface of the upper cylinder 12 is far away from the lower cylinder 13. The lower end surface of the lower cylinder 13 is provided with a lower cylinder cover 131, and the lower end surface of the lower cylinder 13 is far away from the upper cylinder 12.

In one embodiment, if the upper cylinder 12 is the first cylinder, one of said silencers is an upper silencer (not shown) provided at the upper head 121; in another embodiment, if the lower cylinder 13 is the first cylinder, one of the silencers is a lower silencer (not shown) provided at the lower head 131.

During actual exhaust: one path of gas enters the upper cylinder 12, is compressed by the upper cylinder 12 and then is discharged to a silencing cavity of the upper silencer, and is discharged to an exhaust port from the silencing cavity of the upper silencer so as to be discharged out of the compressor 10; meanwhile, the other path of gas enters the lower cylinder 13, is compressed by the lower cylinder 13, is discharged to the discharge cavity 151 of the intermediate partition 15, is directly discharged to the other discharge port from the discharge cavity 151 of the intermediate partition 15, and is discharged out of the compressor 10.

Alternatively, in actual exhaust, the following may be used: one path of gas enters the lower cylinder 13, is compressed by the lower cylinder 13 and then is discharged to a silencing cavity of the lower silencer, and is discharged to an exhaust port from the silencing cavity of the lower silencer so as to be discharged out of the compressor 10; meanwhile, the other path of gas enters the upper cylinder 12, is compressed by the upper cylinder 12, is discharged to the discharge cavity 151 of the intermediate partition 15, is directly discharged to the other discharge port from the discharge cavity 151 of the intermediate partition 15, and is discharged out of the compressor 10.

Here, because the upper cylinder 12 and the lower cylinder 13 respectively suck and exhaust air, two operation modes with different cylinder displacement can be designed, and further, when each exhaust port is connected with one condenser in the air conditioning system, the compressor 10 can be simultaneously connected with two independent condensers, so that the overall use performance of the compressor is improved. The condensing temperature of the two condensers can be the same or different, and the compressor can output two different exhaust temperatures according to different requirements, so that the energy-saving effect is achieved. And because the machining precision of the intermediate partition plate is higher than that of the silencer, the tightness of the exhaust gas of the compressor is better.

In this embodiment, the heat exchange areas of the two condensers may be different, the two cylinders respectively correspond to one exhaust pressure, the exhaust pressures of the two cylinders may be the same or different, and the preferred exhaust pressures are different.

Further, the housing 11 includes a body, an upper housing cover 113 is disposed at an upper end of the body, a lower housing cover 114 is disposed at a lower end of the body, the upper housing cover 113 is close to the motor 14, and the lower housing cover 114 is close to the cylinder. The two exhaust ports are an upper exhaust port 111 and a lower exhaust port 112 respectively arranged on the shell 11, the upper exhaust port 111 is connected with one of the condensers, and the lower exhaust port 112 is connected with the other condenser. It should be understood that the terms "upper and lower" are not used herein to limit the relative positions of the two exhaust ports.

Preferably, the upper exhaust port 111 is provided on the upper housing cover 113, the lower exhaust port 112 is provided on the housing at the end of the compressor near the lower housing cover 114, for example, when the compressor 10 is vertically installed, the lower exhaust port 112 is provided on the end of the housing below the motor 14, and in particular, the lower exhaust port 113 may be configured as an exhaust pipe which is inserted into an exhaust hole of the middle partition 15 through the housing 11 to exhaust air. Similarly, the upper exhaust port 111 may be configured as an exhaust pipe provided on the housing 11.

In an alternative arrangement, one path of the compressed gas from the upper cylinder 12 exits the compressor 10 through the lower exhaust port 112, while the other path of the compressed gas from the lower cylinder 13 exits the compressor 10 through the upper exhaust port 111. At this time, one path of gas compressed by the upper cylinder 12 is discharged to the discharge chamber 151 of the intermediate partition 15 and directly discharged from the discharge chamber 151 to the lower discharge port 112, and the other path of gas compressed by the lower cylinder 13 is discharged to the muffler chamber of the lower muffler and from the muffler chamber to the upper discharge port 111. This constitutes a first exhaust structure.

In another alternative, one path of the compressed gas in the upper cylinder 12 is discharged out of the compressor 10 through the upper discharge port 111, and the other path of the compressed gas in the lower cylinder 13 is discharged out of the compressor 10 through the lower discharge port 112. Here, one path of gas compressed by the upper cylinder 12 is discharged to the muffling chamber of the upper muffler and is discharged from the muffling chamber to the upper exhaust port 111, while the other path of gas compressed by the lower cylinder 13 is discharged to the exhaust chamber 151 of the intermediate partition 15 and is discharged from the exhaust chamber 151 to the lower exhaust port 112. Thus, the second exhaust structure is constructed.

Compared with the first exhaust structure, the second exhaust structure has relatively short exhaust path, so that exhaust resistance can be reduced, and the working efficiency of the compressor can be improved. Therefore, when any one of the upper cylinder 12 and the lower cylinder 13 is the first cylinder, it is preferable that the gas discharged from the muffler chamber is discharged out of the compressor through the upper discharge port 111, and the gas discharged from the discharge chamber of the intermediate partition is directly discharged out of the compressor through the lower discharge port 112.

In the embodiment of the present invention, a gas flow passage (not shown) is provided in the casing 11, and when a path of gas compressed by the upper cylinder 12 is discharged from the compressor through the upper discharge port 111, the path of gas discharged from the muffling chamber of the upper muffler is discharged to the upper discharge port 111 through the gas flow passage. Or, when one path of gas compressed by the lower cylinder 13 is discharged from the compressor through the upper exhaust port 111, the one path of gas discharged from the muffling chamber of the lower muffler is also discharged to the upper exhaust port 111 through the gas flow channel.

Further, when the gas compressed by the upper cylinder 12 is discharged through the discharge chamber 151, the upper muffler is eliminated, so that the height of the motor 14 with respect to the pump body is reduced, the force of the compressor is reduced, the abrasion of the pump body is reduced, and the reliability of the compressor is improved. Or, the gas compressed by the lower cylinder 13 is discharged through the exhaust chamber 151, so that the lower silencer can be eliminated, the height of the whole compressor can be reduced, and the noise performance of the compressor can be improved.

In this embodiment, the intermediate partition 15 is provided with an air inlet (not shown) penetrating the exhaust cavity 151, and the air compressed by the corresponding cylinder is exhausted to the exhaust cavity 151 through the air inlet. Meanwhile, the middle partition 15 is further provided with an air outlet hole communicated with the air discharge cavity 151, and air is discharged from the air discharge cavity 151 through the air outlet hole and enters the lower air discharge port 112.

In one embodiment, the intermediate partition 15 is formed by stacking two sub-panels one on top of the other. For example, only the first sub-plate adjacent to the upper cylinder 12 is opened with an exhaust chamber 151 and an intake hole penetrating the exhaust chamber 151, so that the gas compressed by the upper cylinder 11 is exhausted to the exhaust chamber 151 of the first sub-plate through the intake hole. Alternatively, as shown in fig. 1, an exhaust cavity 151 and an intake hole penetrating through the exhaust cavity 151 are formed in the second sub-plate close to the lower cylinder 13, so that the gas compressed by the lower cylinder 13 is exhausted to the exhaust cavity 151 of the second sub-plate through the intake hole. In other embodiments, the two daughter boards may be recessed to face each other to form a venting chamber 151. In addition, when the upper cylinder 12 exhausts air to the intermediate partition 15, only one groove may be formed on the second sub-plate to form the exhaust cavity 151, and an air inlet hole communicated with the exhaust cavity may be formed on the first sub-plate; similarly, when the lower cylinder 13 exhausts air to the intermediate partition 15, only one groove may be formed on the first sub-plate to form the exhaust cavity 151, and an air inlet hole communicated with the exhaust cavity may be formed on the second sub-plate.

Further, a valve structure (not shown) is installed in the upper cylinder 12 or the lower cylinder 13, and the opening and closing of the valve structure is determined by the gas pressure borne by the surface; when the gas pressure is greater than or equal to the maximum pressure that the valve structure can bear, the valve structure is opened; the valve structure closes when the gas pressure is less than the maximum pressure that the valve structure can withstand. Specifically, as the gas in the upper cylinder 12 or the lower cylinder 13 is compressed, the pressure of the gas in the upper cylinder 12 or the lower cylinder 13 increases accordingly, and when the sucked gas is accumulated to a certain extent, so that the pressure of the gas in the upper cylinder 12 or the lower cylinder 13 reaches the maximum pressure which can be borne by the valve structure, the valve structure is opened, and the gas enters the gas inlet hole (not shown) through the valve structure and finally enters the gas exhaust cavity. More preferably, the valve structure may also prevent the compressed gas from flowing back into the upper cylinder 12 or the lower cylinder 13.

It should be added that, since the installation position of the silencer is known to those skilled in the art, those skilled in the art should know how to implement the above-mentioned several exhausts based on the disclosure of the present application. In addition, the main function of the silencing cavity is to reduce the exhaust noise of the compressor, and the exhaust cavity can also reduce the exhaust noise of the compressor besides the exhaust.

Finally, according to the technical scheme provided by the embodiment of the invention, the exhaust structure of the compressor comprises a silencer, a middle partition plate with an exhaust cavity and two exhaust ports arranged on a shell of the compressor, so that one path of gas is compressed by a first cylinder of the compressor and then exhausted to the silencing cavity of the silencer, and is exhausted to one exhaust port from the silencing cavity, and then is exhausted out of the compressor, and the other path of gas is compressed by a second cylinder of the compressor and then is exhausted to the exhaust cavity of the middle partition plate, and is exhausted to the other exhaust port from the exhaust cavity, and then is exhausted out of the compressor. Here, because two cylinders inhale respectively, the exhaust, consequently, can design into the different mode of operation of two cylinder discharge capacities, and then when each gas vent connects a condenser in the air conditioning system, can make the compressor connect two independent condensers simultaneously, improve the whole performance of compressor, and different condensers can possess the same or different condensation temperature, and the compressor can be according to different demands, exports two different exhaust temperature, reaches energy-conserving effect. And because the machining precision of the intermediate partition plate is higher than that of the silencer, the tightness of the exhaust gas of the compressor is better.

Finally, it should be noted that the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
