It can be understood by those skilled in the art that, the device structure shown in
In the system architecture platform 100 shown in
Based on the hardware structure of the system architecture platform 100, various embodiments of the air conditioner of the present disclosure are provided.
As shown in
In an embodiment, the air conditioner of the embodiment of the present disclosure includes, but is not limited to, a compressor 200, an outdoor heat exchanger 300, an indoor heat exchanger 400, a water tray, an enthalpy increasing system and a gas bypass 600. The outdoor heat exchanger 300 is connected to the indoor heat exchanger 400 through a first refrigerant flow path. The first refrigerant flow path includes a flow path branch, that is, a second refrigerant flow path. The first refrigerant flow path is capable of being connected to an enthalpy increasing port of the compressor 200 through the second refrigerant flow path. In addition, the enthalpy increasing system includes a one-way electromagnetic valve 510 in the second refrigerant flow path. The water tray is located below the outdoor heat exchanger 300. The gas bypass 600 is arranged in the first refrigerant flow path and located between the enthalpy increasing system and the indoor heat exchanger 400, and is also arranged at the water tray.
It should be noted that, the compressor 200 mentioned above is an enhanced vapor injection compressor 200, which adopts two-stage throttling intermediate gas injection technology, and uses a flash evaporator 520 for gas-liquid separation to achieve enthalpy increasing effect. By compressing and injecting gas at medium and low pressure to mix and cool the gas, and then compressing the gas normally at high pressure, an exhaust capacity of the compressor 200 is improved, and a purpose of improving heating capacity in low temperature environment is achieved.
In addition, it should be noted that, the enthalpy increasing system mentioned above can improve a heat extraction process in a heating mode, so that more outdoor heat can be sent indoors. Based on the enhanced vapor injection compressor 200, the enthalpy increasing system optimizes the medium-pressure refrigerant injection technology, inhales a part of the gas with intermediate pressure through the intermediate-pressure suction hole, and then mixes the part of the gas with the partially compressed refrigerant for recompression, thus realizing two-stage compression within a single compressor 200, increasing the refrigerant flow in the condenser and increasing the enthalpy difference of the main circulation loop, and improving the efficiency of the compressor 200. In an embodiment, the compressor 200 of enhanced vapor injection technology has an additional second suction port to cool the refrigerant in the main cycle by generating vapor. The vapor enters the compressor 200 from the second suction port, and the vapor compression process is divided into two stages by the gas supplement process, and the vapor compression process becomes a quasi-two-stage compression process. Gas injection reduces the exhaust temperature, the exhaust superheat, and a length of the gas-phase heat exchange area of the condenser, and increases the two-phase heat exchange area, thus improving the heat exchange efficiency of the condenser. The greater the difference between an evaporation temperature and a condensation temperature, the better the effect is, so the effect will be more obvious in the low temperature environment.
In addition, it should be noted that the embodiment of the present disclosure includes the gas bypass 600 located at the water tray. In an embodiment, during the heating period, the outdoor heat exchanger 300 generates condensed water and drip the water into the water tray. If the outdoor ambient temperature is relatively low, the condensed water in the water tray may be frosted or frozen, thus blocking the water tray. Therefore, the embodiment of the present disclosure adopts the gas bypass 600 to perform defrosting or deicing treatment. In an embodiment, in the heating mode, the refrigerant enters the indoor heat exchanger 400 from a gas exhaust hole of the compressor 200 and releases heat to the indoor environment, and then exits the indoor heat exchanger 400 and enters the gas bypass 600. Although the gas exiting the indoor heat exchanger 400 has released heat at this time, its temperature is still in a high heat state, so the gas bypass 600 is also in a high heat state at this time, and capable of defrosting or deicing.
It should be noted that, the gas bypass 600 of the embodiment of the present disclosure includes, but is not limited to, a plurality of U-shaped pipes spliced in sequence, so that the gas bypass 600 has large area and better defrosting effect.
In addition, it should be noted that, the air conditioner of the embodiment of the present disclosure further includes a drainage device, where one end of the drainage device is located at the water tray and configured to extract the condensed water in the water tray, and another end of the drainage device is configured to spray the condensed water to the indoor heat exchanger 400.
The embodiment of the present disclosure is capable of using the hot gas bypass, namely the gas bypass 600, to heat the water tray of the outdoor unit to ensure that the water temperature is higher than the freezing or frosting temperature, and then spray the water of the outdoor unit to the indoor unit through the drainage device, thus achieving the humidification effect.
It can be understood that, the one-way electromagnetic valve 510 may be a split combination structure of a one-way valve and an electromagnetic valve, or an integrated combination structure of the one-way valve and the electromagnetic valve.
It should be noted that, the air conditioner in the embodiment of the present disclosure may be a window-mounted air conditioner or a split air conditioner, and the structural form of the air conditioner is not specifically limited in the embodiment of the present disclosure.
In an embodiment, the enthalpy increasing system in the air conditioner of the embodiment of the present disclosure further includes a flash evaporator 520, which includes a first refrigerant flow hole, a second refrigerant flow hole and a third refrigerant flow hole. The flash evaporator 520 is connected to the enthalpy increasing port of the compressor 200 through the first refrigerant flow hole and the one-way electromagnetic valve 510 sequentially. The flash evaporator 520 is connected to the outdoor heat exchanger 300 through the second refrigerant flow hole. The flash evaporator 520 is connected to the gas bypass 600 through the third refrigerant flow hole.
It can be understood that, the flash evaporator 520 mentioned above can realize flash evaporation. The flash evaporation refers to a phenomenon that after saturated liquid with high pressure enters a relatively low pressure container, the saturated liquid become saturated vapor and saturated liquid in combination under the pressure of a part of the container due to the sudden drop of pressure.
In an embodiment, the enthalpy increasing system in the air conditioner of the embodiment of the present disclosure further includes a throttling device, which is arranged in the first refrigerant flow path and located between the outdoor heat exchanger 300 and the gas bypass 600.
In an embodiment, the throttling device mentioned above may include a first throttling device 530 and/or a second throttling device 540. The first throttling device 530 is arranged in the first refrigerant flow path and located between the outdoor heat exchanger 300 and the second refrigerant flow hole. The second throttling device 540 is arranged in the first refrigerant flow path and located between the third refrigerant flow hole and the gas bypass 600.
In an embodiment, a respective one of the first throttling device 530 and the second throttling device 540 mentioned above may be an electronic expansion valve or a capillary tube.
It can be understood that, the capillary tube mentioned above is the simplest throttling device of the air conditioner. Generally, the capillary tube is a copper tube which has a specified length and an inner diameter of 0.5 mm to 2 mm. Advantages of such an arrangement are convenient manufacture and low price, and the disadvantage is that there is no function to adjust the flow.
In addition, it can be understood that, the structure of the electronic expansion valve mentioned above may be composed of three parts: detection, control and execution. Advantages of such an arrangement are wide flow adjustment range and high control precision, and it is suitable for intelligent control and can adapt to the rapid change of refrigerant flow with high efficiency. In other words, the electronic expansion valve can be regarded as an intelligent capillary tube with variable inner diameter.
In an embodiment, the throttling device is capable of throttling liquid refrigerant with medium-temperature and high-pressure into wet vapor with low-temperature and low-pressure, and then the refrigerant absorbs heat in the evaporator to achieve the refrigeration effect. The expansion valve controls valve flow through change of superheat at an end of the evaporator to prevent the underutilization of evaporator area and cylinder knocking.
In an embodiment, the air conditioner of the embodiment of the present disclosure further includes a four-way valve 700 respectively communicated with the outdoor heat exchanger 300, the indoor heat exchanger 400, and a gas return hole and the gas exhaust hole of the compressor 200.
In an embodiment, the air conditioner of the embodiment of the present disclosure further includes a muffler 800 between the four-way valve 700 and the gas exhaust hole of the compressor 200.
The refrigeration operation flow of the embodiment of the present disclosure is as follows: the refrigerant comes out of the gas exhaust hole of the compressor 200, enters the outdoor heat exchanger 300 through the four-way valve 700, comes out of the outdoor heat exchanger 300, passes through the first throttling device 530 and enters the flash evaporator 520 which is in a full-operation state. In this case, the one-way electromagnetic valve 510 is in a closed state, so that gas cannot enter the enthalpy increasing port of the compressor 200, that is, the gas supplement port. The refrigerant coming out of the flash evaporator 520 is throttled by the second throttling device 540, and then enters the indoor heat exchanger 400 through the gas bypass 600. The refrigerant evaporates in the indoor heat exchanger 400 and becomes gas, and then returns to the gas return port of the compressor 200 through the four-way valve 700.
The heating operation flow of the embodiment of the present disclosure is as follows: the refrigerant comes out of the gas exhaust hole of the compressor 200, enters the indoor heat exchanger 400 through the four-way valve 700, comes out of the indoor heat exchanger 400 into the gas bypass 600, comes out of the gas bypass 600 and enters the flash evaporator 520 through the second throttling device 540. Then the gas enters the enthalpy increasing port of the compressor 200, that is, the gas supplement port, through the one-way electromagnetic valve 510, and at the same time, the liquid enters the outdoor heat exchanger 300 after being throttled through the first throttling device 530, and then comes out of the outdoor heat exchanger 300 and returns to the gas return port of the compressor 200 through the four-way valve 700.
It can be understood that, the structure of the controller mentioned above may include a processor 110 and a memory 120 as shown in
It can be understood by those having ordinary skills in the art that, the structure described above is not limited to the air conditioner, and may include more or less components than shown, or combine some components, or have different component arrangements.
Based on the above system architecture platform 100 and the hardware structure of the air conditioner, various embodiments of the ice melting method for the air conditioner of the present disclosure are provided.
As shown in
At the step S100, an icing condition in the water tray is detected.
At the step S200, the icing condition indicates ice existing in the water tray.
At the step S300, an operating state of the air conditioner is adjusted to improve heat supply of the gas bypass.
In an embodiment, the outdoor heat exchanger is prone to frosting in the heating mode, especially at low temperature. The air conditioner collects the defrosted water into the water tray through periodical defrosting and discharges the defrosted water through the drainage hole. Since the external environment temperature is too low, and the defrosted water is prone to freezing in the water tray, a corresponding sensor detects the icing condition in the water tray, so as to determine whether to carry out the ice melting operation. In an embodiment, the air conditioner includes an ice detection sensor, by which the condition in the water tray is detected. When ice existing in the water tray is determined, the operating state of the air conditioner is adjusted to improve the heat supply of the gas bypass. Since the gas bypass is arranged at the water tray, the ice in the water tray can be melted, and the normal operation of the air conditioner is prevented from being affected by the freezing of the water tray. It can be understood that, an architecture of the air conditioner mentioned in the embodiment of the second aspect of the present disclosure may refer to the architecture of the air conditioner in the embodiment of the first aspect of the present disclosure, and is not repeated here.
In addition, as shown in
At the step S410, the ice detection sensor detects resistance in the water tray.
At the step S420, when the resistance is higher than a preset resistance threshold, it is determined that ice exists in the water tray.
In an embodiment, the ice detection sensor detects the resistance of the water/ice/ice-water mixture in the water tray. Since the resistance of water, ice and ice-water mixture is different, the amount of ice in the water tray may be determined by comparing the resistance detected by the ice detection sensor with the preset resistance threshold. The resistance of ice is higher than the resistance of water, and the resistance of ice-water mixture is between the resistance of ice and the resistance of water. When the detected resistance is greater than the preset resistance threshold, the proportion of ice in the water tray is determined to exceed a certain degree, and the ice melting operation may be performed.
In addition, as shown in
At the step S500, when the resistance is lower than or equal to the preset resistance threshold, it is determined that ice does not exist in the water tray.
In an embodiment, the ice detection sensor detects the resistance of the water/ice/ice-water mixture in the water tray. Since the resistance of water, ice, and ice-water mixture is different, the amount of ice in the water tray may be determined by comparing the resistance detected by the ice detection sensor with the preset resistance threshold. The resistance of ice is higher than the resistance of water, and the resistance of ice-water mixture is between the resistance of ice and the resistance of water. When the detected resistance is less than or equal to the preset resistance threshold, the proportion of ice in the water tray is determined to be small, and performing ice melting operation is unnecessary at this time.
In addition, as shown in
At the step S610, the one-way electromagnetic valve is kept open an opening degree of the throttling device is maintained.
At the step S620, the operating frequency of the compressor is increased, a rotation speed of an indoor fan is decreased, and a rotation speed of an outdoor fan is maintained.
In an embodiment, it can be known from the above heating mode that during the heating operation, both the first throttling device and the second throttling device are in an open state, and the one-way electromagnetic valve is in an open state. When entering an ice melting mode, the air conditioner maintains the heating mode, that is, the one-way electromagnetic valve is kept open, the opening degrees of the first throttling device and the second throttling device are maintained, and then the operating frequency of the enhanced vapor injection compressor is increased, the rotation speed of the outdoor fan remains unchanged, and the rotation speed of the indoor fan is decreased. Since the rotation speed of the indoor fan is decreased, the heat exchange level of the indoor heat exchanger decreases. Since the opening degrees of the first throttling device and the second throttling device remain unchanged, more heat of the refrigerant is distributed to the gas bypass to melt the ice, and at the same time. The operating frequency of the compressor is increased to improve the heat exchange capacity in the refrigerant pipeline, thereby in turn improving the ice melting efficiency.
In addition, as shown in
At the step S700, the rotation speed of the indoor fan is decreased to keep a temperature of the indoor heat exchanger higher than a first preset temperature.
In an embodiment, the first preset temperature may be 52° C. Since the rotation speed of the indoor fan is decreased, the heat exchange efficiency between indoor air and indoor heat exchanger decreases, and the temperature increases. In order to ensure more heat supply to the gas bypass, the temperature of the indoor heat exchanger is limited by the first preset temperature. The temperature of the indoor heat exchanger cannot be lower than 52° C. Therefore, the lowest rotation speed of the indoor fan can be decreased to 0, that is, the indoor fan is turned off.
In addition, as shown in
At the step S810, the resistance or a temperature in the water tray is re-detected at every preset time.
At the step S820, it is determined whether to continue ice melting according to the detected resistance or temperature.
In an embodiment, for example, after the ice melting operation is performed, a timer is set inside the air conditioner. When the timer reaches the preset time, the resistance in the water tray is re-detected through the ice detection sensor, or the temperature in the water tray is re-detected through a temperature sensor. When the resistance is lower than the preset resistance threshold (indicating that the proportion of ice in the water tray is low to a certain extent) or the temperature is higher than a certain value (such as above 0° C.), the ice melting operation is ended and the aforementioned heating mode is returned. The temperature detection and determination may be performed in the following way: when the temperature collected by the temperature sensor at the water tray is more than a certain value for more than 10 seconds, the ice in the water tray is completely melted by default, and the ice melting operation may be ended.
Based on the ice melting method for the air conditioner in the above embodiments, detail description of the ice melting method for the air conditioner in the present disclosure is set forth below.
