Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by way of embodiments and with reference to the accompanying drawings. 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.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings). In the description of the present application, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present application and for simplicity in description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be considered as limiting the present application.
In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
In the using process of the air conditioner, if the phenomenon of insufficient refrigerant storage or refrigerant leakage occurs, the exhaust pressure and the suction pressure of the compressor 110 in the air conditioning system are both lower. The load of the motor is reduced while causing an increase in the output torque of the compressor 110. Because the heat dissipation of the compressor 110 cannot be taken away by the refrigerant flowing in a sufficient amount in time, if the compressor is an external protector, the motor cannot be protected in time, and the service life of the motor is influenced because the motor works at a high temperature.
In addition, when an excessive amount of refrigerant is added into the air conditioning system, the refrigerant dilutes the lubricant oil to reduce the viscosity of the lubricant oil, so that the wear parts of the compressor 110, such as the roller, the cylinder, the crankshaft, and the vane, cannot be effectively lubricated, and the wear is increased. In addition, liquid slugging can occur, which can cause fatal damage to the pump body of the compressor 110. When the refrigerant is filled too much, the suction end is left with more liquid refrigerant, which increases the load force. The output torque of the refrigerant compressor 110 may be small.
In the after-sale maintenance process, a phenomenon that part of maintenance workers falsely report faults and mislead users to add refrigerants exists. In addition, after sale, the refrigerant adding process has strong subjectivity, and the amount of the added refrigerant is different according to different people. The specific amount and the remaining amount of the refrigerant cannot be known to consumers. Therefore, there is a need for a device capable of detecting the storage amount of refrigerant, so as to provide visual data for consumers and maintain the legitimate rights of consumers.
Referring to fig. 1, an embodiment of the present application provides a method for detecting an amount of refrigerant stored. The refrigerant storage capacity detection method comprises the following steps:
s10, measuring the output torque value of the compressor 110 in the air conditioner;
and S20, judging whether the content of the refrigerant in the air conditioner is in a preset range according to the output torque value.
In S10, the compressor 110 may be configured to compress a refrigerant in an air-conditioning refrigerant circuit. The compressor 110 may be installed outdoors. The compressor 110 may extract the refrigerant from the low pressure region, compress the refrigerant, and send the compressed refrigerant to the high pressure region for cooling and condensation, and emit heat to the air through the heat sink, and the refrigerant is changed from a gas state to a liquid state, and the pressure is increased. The compressor 110 operates to generate an output torque value. The refrigerant can be acted by the output torque value.
In S20, when the refrigerant of the air conditioning system is insufficient, both the discharge pressure and the suction pressure of the compressor 110 are relatively low. The load of the motor driving the compressor 110 is reduced, thereby causing an increase in the output torque value of the compressor 110. When the refrigerant in the air conditioning system is excessive, a large amount of liquid refrigerant remains at the air suction end of the air conditioning system, so that the load capacity is increased, and the output torque value of the compressor 110 is small. Therefore, the content of the refrigerant in the air conditioner can be judged according to the magnitude of the output torque value. It is understood that the correspondence relationship between the refrigerant content in the air conditioner and the output torque value may be determined by an empirical value or calculation. And determining the content range of the refrigerant in the air conditioner according to the range of the output torque value of the compressor 110 during normal operation. The content range of the refrigerant can be used as the preset range.
The refrigerant storage amount detection method provided by the embodiment of the application firstly measures the output torque value of the compressor 110 in the air conditioner, and then judges whether the content of the refrigerant in the air conditioner is in a preset range according to the output torque value. That is, the magnitude of the output torque value of the compressor 110 is related to the refrigerant content in the air conditioner. By establishing the corresponding relationship between the refrigerant content in the air conditioner and the output torque value, the refrigerant content in the air conditioner can be determined when the compressor 110 normally works, and then the amount of the refrigerant content in the air conditioner can be judged according to the magnitude of the output torque value, so that measures for supplementing the refrigerant or discharging the refrigerant can be taken timely, the normal work of the air conditioner is ensured, and the service life of the air conditioner can be prolonged.
Referring to fig. 2, in one embodiment, the S20 includes: and S21, when the output torque value is larger than a first preset value and smaller than a second preset value, judging that the content of the refrigerant in the air conditioner is in a normal range. Wherein the first preset value is smaller than the second preset value.
The first preset value may be an output torque value of the compressor 110 corresponding to a minimum value of the refrigerant content when the air conditioner is maintained to normally operate. The second preset value may be an output torque value of the compressor 110 corresponding to a maximum value of the refrigerant content for maintaining normal operation of the air conditioner. The output torque of the compressor 110 can be quantized by setting the first preset value and the second preset value, so that the working state of the compressor 110 can be known in time, and the content of the refrigerant in the air conditioner can be adjusted in time.
Referring to fig. 3, in one embodiment, the S20 includes: and when the output torque value is smaller than the first preset value, judging that the refrigerant in the air conditioner is excessive. It can be understood that when the refrigerant in the air conditioning system is excessive, more liquid refrigerant remains at the air suction end of the air conditioning system, so that the load force is increased, and the output torque value of the compressor 110 is smaller. Therefore, when the output torque value of the compressor 110 is smaller than the first preset value, it may be determined that the refrigerant in the air conditioner is excessive, and at this time, a measure of stopping or releasing the refrigerant in the air conditioner may be taken.
Referring to fig. 4, in one embodiment, the S20 includes: and when the output torque is larger than the second preset value, judging that the refrigerant in the air conditioner is insufficient.
When the refrigerant of the air conditioning system is insufficient, the discharge pressure and the suction pressure of the compressor 110 are relatively low. The load of the motor driving the compressor 110 is reduced, thereby causing an increase in the output torque value of the compressor 110. Therefore, when the output torque of the compressor 110 is greater than the second preset value, it may be determined that the refrigerant in the air conditioner is insufficient. When the lack of the refrigerant in the air conditioner is known through the output torque of the compressor 110, the refrigerant can be added into the air conditioner in time, and the normal work of the air conditioner is ensured.
In one embodiment, when the content of the refrigerant in the air conditioner is not within a preset range, the air conditioner is controlled to stop working. This indicates that the refrigerant in the air conditioner is either excessive or insufficient. Insufficient refrigerant may cause the heat generated by the compressor 110 to be not carried away in time by the refrigerant flowing sufficiently. Causing damage to the motor. If the refrigerant is excessive, the refrigerant may dilute the lubricant to reduce the viscosity of the lubricant, so that the wear parts of the compressor 110, such as the roller, the cylinder, the crankshaft, and the vane, may not be effectively lubricated, which may cause the wear to be aggravated and the service life of the air conditioner to be affected, and thus the air conditioner may need to be timely controlled to stop working.
Referring to fig. 5, an embodiment of the present application further provides a device 10 for detecting an amount of refrigerant stored. The refrigerant storage amount detection device 10 includes a sensor 140 and a processor 120. The sensor 140 is used to be disposed at the compressor 110 of the air conditioner. The sensor 140 is used to monitor the output torque of the compressor 110 and to generate a torque signal. The processor 120 is coupled to the sensor 140. The processor 120 is configured to determine whether the content of the refrigerant in the air conditioner is within a preset range according to the torque signal. The torque sensor 140 may be a contactless torque sensor 140 or a strain gauge torque sensor 140, etc. The torque signal may carry an output torque value of the compressor 110. The voltage of the torque signal may be positively correlated with the force applied to the sensor 140.
The processor 120 may store the first preset value and the second preset value. The magnitude of the output torque value can be judged by the relation between the torque signal voltage and the first threshold voltage and the second threshold voltage. Wherein the first preset value may correspond to a first threshold voltage. The second preset value may correspond to a second threshold voltage.
The processor 120, upon receiving the torque signal, may compare the output torque value with the first preset value and the second preset value. And when the output torque value is larger than a first preset value and smaller than a second preset value, judging that the content of the refrigerant in the air conditioner is in a normal range. And when the output torque value is smaller than the first preset value, judging that the refrigerant in the air conditioner is excessive. And when the output torque is larger than the second preset value, judging that the refrigerant in the air conditioner is insufficient. The first preset value corresponds to the maximum refrigerant content of the air conditioner during normal operation. The second preset value corresponds to the minimum refrigerant content of the air conditioner during normal operation.
In one embodiment, the refrigerant storage amount detection apparatus 10 further includes an alarm device 130. The alerting device 130 is coupled to the processor 120. The warning device 130 is used for prompting the content state of the refrigerant in the air conditioner. When the output torque value is smaller than the first preset value or the output torque value is greater than the second preset value, the warning device 130 may generate a warning sound or a warning picture to prompt addition or reduction of refrigerant content in the air conditioner. When the output torque value is greater than the first preset value and less than the second preset value, the warning device 130 may also send a prompt that the refrigerant content is normal.
In one embodiment, the alerting device 130 comprises a hand-held device. The hand operator is connected with the processor 120. The manual operator is used for displaying the content state of the refrigerant in the air conditioner. The hand operator can be a portable instrument terminal. The manual operator can display through the LED nixie tube and acquire information sent by the processor 120 in real time. In one embodiment, the hand operator may communicate with the processor 120 via a CAN bus. When the amount of refrigerant in the air conditioner is excessive or insufficient, the processor 120 may send a signal of the refrigerant excess or lack to the hand operator. The manual operator can display words such as 'excessive refrigerant' or 'insufficient refrigerant' and the like.
In one embodiment, the refrigerant storage amount detection apparatus 10 further includes a controller 150. The first end of the controller 150 is connected to the processor 120. A second end of the controller 150 is adapted to be coupled to the compressor 110. The processor 120 controls the operating state of the compressor 110 through the controller 150. The processor 120 may send instructions to the controller 150. The controller 150 may control the compressor 110 to operate or stop according to the instruction of the processor 120.
An embodiment of the present application also provides an air conditioner. The air conditioner includes the refrigerant storage amount detection device 10 provided in the above embodiment. The air conditioner includes the compressor 110. The refrigerant storage amount detection device 10 is connected to the compressor 110. I.e. the sensor 140 may try to monitor the output torque of the compressor 110 and send a torque signal. The processor 120 may determine whether the content of the refrigerant in the air conditioner is within a preset range according to the torque signal. When the output torque of the compressor 110 is within a preset range, it may be considered that the air conditioner is normally operated. When the output torque of the compressor 110 is greater than the first preset value or less than the second preset value, it indicates that the refrigerant in the air conditioner is insufficient or excessive, and the content of the refrigerant in the air conditioner needs to be adjusted. Therefore, the air conditioner has the function of judging the content of the refrigerant, the air conditioner can work under the condition that the refrigerant has normal content, and the service life of the air conditioner is prolonged.
