Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides a control method of an air conditioner. The air conditioner is capable of operating a compression mode and an air pump mode. The air conditioner comprises two working modes, namely a compression mode and an air pump mode. When the outdoor temperature T0 is equal to or higher than the preset temperature T, the compression mode is operated while the throttling element 4 is operated. When the outdoor temperature T0 is lower than the preset temperature T, the air pump mode is operated, and the control valve 3 is opened, for example, the control valve may be a solenoid valve, and when the air pump mode is operated, the solenoid valve is electrically conducted.
In one embodiment, the air conditioner includes: the compressor and the air pump are connected in parallel, and the compression mode and the air pump mode can be operated and switched.
Fig. 2a is a schematic structural diagram of an air conditioner according to an embodiment of the present invention. As shown in fig. 2a, the air conditioner includes a compressor 1, a first stop valve 11, an air pump 6, a second stop valve 61, a condenser 2, a throttling element 4, and an evaporator 5, which are connected in sequence by a pipeline, wherein the throttling element 4 may be an electronic expansion valve 4. By adjusting the opening of the throttling element, the two working modes of the compression mode and the air pump mode can be realized by matching with the opening and closing of the first stop valve 11 at the compressor or the opening and closing of the second stop valve 61 at the air pump 6.
Optionally, a control valve 3 is further disposed between the condenser 2 and the evaporator 5, and is connected in parallel with the throttling element 4, the throttling element 4 may specifically be an electronic expansion valve, and the control valve 3 may specifically be a solenoid valve, an electronic expansion valve, or an electric flow regulating valve.
For example, the combination of the solenoid valve 3 and the electronic expansion valve 4 may be replaced by a single electronic expansion valve, or two electronic expansion valves connected in parallel, or an electric flow control valve connected in parallel with the electronic expansion valves.
Two working modes of a compression mode and an air pump mode can be realized by controlling the switch of the control valve 3. For example, when the control valve 3 is an electromagnetic valve, the air-conditioning operation air pump mode is implemented when the control valve 3 is opened, the first shutoff valve 11 is closed, and the second shutoff valve 61 is opened, and the throttling element 4 is operated when the control valve 3 is closed, and the air-conditioning operation compression mode is implemented when the first shutoff valve 11 is opened and the second shutoff valve 61 is closed.
For example, the air conditioning system has two operation modes, namely a cooling mode and an air pump mode. When the outdoor temperature T0 is greater than or equal to the preset temperature T, the unit starts the compressor operation mode, and at the same time, the air pump 6 and the stop valve 61 are closed, and the electronic expansion valve 4 works. When the outdoor temperature T0 is lower than the preset temperature T, the unit starts the air pump operation air pump mode, and simultaneously closes the compressor 1 and the stop valve 11, and the electromagnetic valve 3 is electrified.
Optionally, a control valve 3 is further disposed between the condenser 2 and the evaporator 5, and is connected in parallel with the throttling element 4, and the control valve 3 may specifically be a solenoid valve, an electronic expansion valve, or an electric flow regulating valve.
For example, the combination of the solenoid valve 3 and the electronic expansion valve 4 may be replaced by a single electronic expansion valve, or two electronic expansion valves connected in parallel, or an electric flow control valve connected in parallel with the electronic expansion valves.
Single electronic expansion valve: the compression mode is normally used in a throttling mode, and the air pump mode is adjusted to be used in a maximum opening degree (in this case, an electronic expansion valve with a large drift diameter is preferably used); two electronic expansion valves in parallel: the compression mode is normally used in a throttling mode, and the air pump mode is adjusted to the maximum opening degree for use. The electric flow regulating valve is connected with the electronic expansion valve in parallel: the compression mode uses an electronic expansion valve for normal throttling use, and the air pump mode uses an electric flow regulating valve for controlling the flow of the system.
Two working modes of a compression mode and an air pump mode can be realized by controlling the switch of the control valve 3. For example, when the control valve 3 is an electromagnetic valve, the air-conditioning operation air pump mode is realized when the control valve 3 is opened, and when the control valve 3 is closed, the throttling element 4 is operated to realize the air-conditioning operation compression mode.
In another embodiment, a cylinder of a compressor of the air conditioner is provided with two exhaust ports having different pressure ratios, and a compression mode or an air pump mode can be implemented by opening the different exhaust ports.
Fig. 2b is a schematic structural view illustrating an air conditioner according to another embodiment of the present invention. As shown in fig. 2, the air conditioner includes a compressor 1, a condenser 2, a throttling element 4, and an evaporator 5, and the throttling element 4 may be an electronic expansion valve 4, and the compressor has two working modes, i.e., a compression mode and an air pump mode. Two working modes of a compression mode and an air pump mode can be realized by adjusting the opening of the throttling element.
Optionally, a control valve 3 is further disposed between the condenser 2 and the evaporator 5, and is connected in parallel with the throttling element 4, and the control valve 3 may specifically be a solenoid valve, an electronic expansion valve, or an electric flow regulating valve.
For example, the combination of the solenoid valve 3 and the electronic expansion valve 4 may be replaced by a single electronic expansion valve, or two electronic expansion valves connected in parallel, or an electric flow control valve connected in parallel with the electronic expansion valves.
Single electronic expansion valve: the compression mode is normally used in a throttling mode, and the air pump mode is adjusted to be used in a maximum opening degree (in this case, an electronic expansion valve with a large drift diameter is preferably used); two electronic expansion valves in parallel: the compression mode is normally used in a throttling mode, and the air pump mode is adjusted to the maximum opening degree for use. The electric flow regulating valve is connected with the electronic expansion valve in parallel: the compression mode uses an electronic expansion valve for normal throttling use, and the air pump mode uses an electric flow regulating valve for controlling the flow of the system.
Two working modes of a compression mode and an air pump mode can be realized by controlling the switch of the control valve 3. For example, when the control valve 3 is an electromagnetic valve, the air-conditioning operation air pump mode is realized when the control valve 3 is opened, and when the control valve 3 is closed, the throttling element 4 is operated to realize the air-conditioning operation compression mode.
Specifically, a cylinder of a compressor of the air conditioner is provided with a first exhaust port and a second exhaust port; the pressure ratio of the exhaust pressure of the first exhaust port to the suction pressure of the cylinder is epsilon 1; the pressure ratio of the discharge pressure of the second discharge port to the suction pressure of the cylinder is epsilon 2, wherein epsilon 1 is larger than epsilon 2.
Two exhaust ports are arranged on the same cylinder: the exhaust pressure ratio of the first exhaust port and the second exhaust port, the two exhaust ports are different, for example, the exhaust pressure ratio can be realized by arranging exhaust valves with different exhaust pressures on each exhaust port, and the cylinders can play different roles by selecting to exhaust from different exhaust ports.
The pressure ratio of the exhaust pressure of the first exhaust port to the suction pressure of the cylinder is larger than the pressure ratio of the exhaust pressure of the second exhaust port to the suction pressure of the cylinder, so that when the first exhaust port exhausts, the cylinder is used as a compression cylinder, and when the second exhaust port exhausts, the cylinder is used as an air pump cylinder; therefore, the cylinder itself is used as a compression cylinder or an air pump cylinder by outputting different pressures to exhaust, which can save the space needed by additionally and separately arranging the air pump, is beneficial to the miniaturization design of the equipment and can also reduce the cost.

When the compression mode is operated, the throttling element 4 works, and when the air pump mode is operated, the control valve 3 is opened, for example, the control valve can be an electromagnetic valve, and when the air pump mode is operated, the electromagnetic valve is electrified and conducted.
For example, the throttling element 4 is an electronic expansion valve, and the control valve 3 is an electromagnetic valve; when the outdoor temperature T0 is equal to or higher than the preset temperature threshold value T, the compression mode is operated while the electronic expansion valve 4 is operated. When the outdoor temperature T0 is less than the preset temperature threshold T, the air pump mode is operated while the solenoid valve 3 is energized.

In one embodiment, the adjusting the rotation speed of the external fan according to the first preset control logic specifically includes: and adjusting the rotating speed of the outer fan according to the suction superheat degree or the exhaust temperature or the exhaust superheat degree of the compressor. For example, when the suction superheat degree or the exhaust temperature or the exhaust superheat degree is smaller than the corresponding preset threshold (i.e., the preset threshold corresponding to each of the suction superheat degree, the exhaust temperature and the exhaust superheat degree), the rotating speed of the external fan is controlled to be increased; when the suction superheat degree or the exhaust temperature or the exhaust superheat degree is larger than a corresponding preset threshold value, controlling the rotating speed of the outer fan to be reduced; and when the suction superheat degree or the exhaust temperature or the exhaust superheat degree is equal to the corresponding preset threshold value, the rotating speed of the outer fan is kept unchanged.
