An example of a specific embodiment according to the present invention is described below with reference to fig. 1.
The invention aims to at least solve the problems that the prior art or the related technology only judges whether fluorine is deficient or not and the resolution ratio of the air conditioner to detect the refrigerant content is low. The scheme can improve the resolution ratio of the air conditioner for detecting the content of the refrigerant, and detect the percentage of the content of the residual refrigerant relative to the content of the full fluorine.
The invention provides a method for detecting the content of a refrigerant of an air conditioner, which comprises the following steps:
s1, enabling an indoor fan of an air conditioner to be in a shutdown state, adjusting the frequency of an outdoor fan and a compressor and the step number of an electronic expansion valve to an experiment set value, and enabling the air conditioner to run for setting experiment time H;
s2, calculating an inner pipe temperature difference (T0 '-T1') in the H time period and determining the percentage of the residual refrigerant quantity of the current air conditioner relative to the refrigerant quantity under the condition of full fluorine based on the inner pipe temperature difference (T0 '-T1');
said § R Practice of /R Datum ＝[(T0′-T1′)/H-K]/R Datum ；
The method comprises the following steps that T0' is an initial pipe temperature T0' in the H time period, T1' is a final pipe temperature in the H time period, K is a compensation value, H is set experiment time, K is a compensation value aiming at deviation of actual test conditions and laboratory test conditions, R reference is an indoor heat exchanger pipe temperature reduction rate reference value corresponding to the current machine type, and different machine types have different reference change rates.
Preferably, the step S0 is performed first, and then the step S1 is performed, where the step S0 includes: and S0, responding to the query instruction, restarting the air conditioner after the air conditioner is stopped for a first set time, and adjusting the load.
Preferably, after the step S2, the method further comprises: and S4, displaying and/or sending the calculation result to a client on a display panel of the air conditioner internal unit.
Preferably, in the step S1, the outdoor fan and compressor frequency and the electronic expansion valve step number are adjusted to the experiment set values: the frequency of the external fan and the compressor, the step number of the electronic expansion valve and the experimental conditions for obtaining the R reference are kept consistent.
Preferably, the compensation value K is determined based on the T inner loop.
Preferably, the T inner loop has a functional relationship with the compensation value K, the functional relationship being K = f (T) Inner ring )
Preferably, the R reference is determined before the air conditioner leaves a factory, and is pre-stored in the air conditioner.
The monitoring method provided by the invention is based on the simplified process and thought as follows:
heat Q released by temperature drop of air conditioner inner pipe (indoor heat exchanger pipe temperature) Releasing Only in relation to the temperature change T of the tube temperature,
Q releasing ＝M*C*(T0-T1),
The refrigerant mass M and the refrigerant specific heat capacity C of the inner pipe cannot be changed. Due to the internal air blower, the heat released by the internal air-conditioning pipe is approximately considered to be equal to the heat taken away by the refrigerant: q Releasing ＝Q Absorption of From this, a formula can be derived: t is unit time
Through simplification:
in a fluorine-deficient system, the mass M of the refrigerant flowing through the inner tube per unit time is reduced, and the substantially constant ratio of the refrigerant temperature can be approximated to 1, whereby the refrigerant content can be detected by detecting the temperature change rate of the inner tube.
Firstly, a reference change rate R is measured for a machine type Reference(s) And the temperature T0 of the inner pipe just started is recorded under the environment, the temperature T1 of the inner pipe is tested after the operation H time, and then the following steps are obtained:
R datum ＝(T0-T1)/H
R Datum As system parameter storage, only one model is used, and different models have different reference change rates. This baseline rate of change is experimentally determined by the tube temperature. Different machine types have different factors such as the number of the machines, the amount of a compressor and the amount of a refrigerant, the factors affect the standard change rate more or less, the temperature reduction degrees of the pipes tested under the same condition at the same time are different, and different machine types need to test different standard change rates. H may be selected to be 5 minutes.
In actual testing, the program sets the stop of the inner fan, the wind gear of the outer fan, the frequency V of the compressor, and the step number S of the electronic expansion valve (the adjustment of the opening of the electronic expansion valve is generally calculated according to steps, and the minimum angle range of the rotation of the stepping motor is called one step because the adjustment structure of the electronic expansion valve of the air conditioner is a stepping motor.
Here, V and S are kept the same as the laboratory, and the internal tube temperature T0 'at startup is also measured, and the internal tube temperature T1' is measured after H operation, and then:
R testing ＝(T0′-T1′)/H
Because the actual test is inconsistent with the inner ring temperature of the laboratory, and the natural radiation speed of the inner tube to the heat of the air under different inner rings is inconsistent, a compensation value K is required to be added to the R test, and the K value is calculated as follows:
keeping the same experimental environment, stopping the inner fan, stopping the outer fan at the middle wind gear, the compressor frequency V, the electronic expansion valve step number S, adjusting the inner ring temperature T and the inner ring (30-0 ℃), then obtaining R under different inner rings,
Kt inner ring ＝R-R Datum
By linear fitting, K and T are obtained Inner ring The relationship of (1):
K＝f(T inner ring )
With the compensation value K, the actual inner tube change rate Ractual under the current inner ring can be calculated by adjusting the R test:
R in fact ＝R Testing -K
Finally, according to the ratio of the change rate of the inner tube temperature and the change rate of the standard full fluorine, the refrigerant content § R is obtained In fact /R Reference(s) ＝[(T0′-T1′)/H-K]/R And (4) benchmark.
It can be seen from the above analysis that the measurement of the fluorine content needs to keep the same experimental environment as the measurement of the standard value, and the parameters of the internal fan stop, the wind gear in the external fan, the compressor frequency V, and the electronic expansion valve step number S are consistent with those in the laboratory, so that the parameters do not affect the test result, but only the refrigerant content affects the pipe temperature.
If the inner ring temperature T is adjusted to be within the range of 30 ℃ to 0 ℃, the tube temperature reduction rate R at each inner ring temperature of 0 ℃ to 30 ℃ is tested. Subtracting the tested data from the reference reduction rate Rbenchmark of 20 ℃ to obtain the difference value KT between the tube temperature reduction rate R and the reference tube temperature reduction rate Rbenchmark at each inner ring temperature Inner ring . Fitting KT inner ring data to obtain a relation between a compensation value and inner ring temperature through simulation, such as K = f (T) Inner ring ). The formula obtained by simulation (such as K = f (T) Inner ring ) And the current inner ring temperature) can be calculated by mathematical operation to obtain the temperature drop rate compensation value at the temperature. The advantage of doing so is that need not to save a plurality of compensation value data to system memory, obtains corresponding interior ring temperature compensation through saving simulation formula operation and saves memory space.
Practical applications, as illustrated in fig. 1: the user uses the air conditioner with the inquired refrigerant content and needs to check the residual refrigerant quantity of the air conditioner at present. And the user uses the remote controller to inquire by one key to enter the refrigerant inquiry state. The air conditioner is stopped for three minutes according to the preset mode by the internal and external machines (waiting for the temperature of the internal pipe to rise again). If now the room temperature is 23 ℃. The air conditioner records the temperature T0 'of the inner tube when the air conditioner is started up immediately after three minutes, records the temperature T1' of the inner tube after running H time, and measures the temperature drop rate of the inner tube in the current test as R test according to the preset value in the air conditioner. At this time, the measured data is not data compared with the reference inner tube temperature drop rate, and a temperature compensation value at the current inner ring temperature needs to be added (the inner ring temperature is different, the heat radiation of the inner tube of the air conditioner is different, and influences are exerted). According to the internal ring temperature 23 ℃ before testing and the internal ring temperature and temperature compensation value formula K = f (T) stored by the system Inner ring ) Converting the temperature compensation value at 23 ℃ to be K 23℃ . Finally, the data are stored according to a refrigerant content requirement formula stored in the system § R In fact /R Reference(s) ＝[(T0′-T1′)/H-K 23℃ ]/R Datum And calculating the current refrigerant content.
The present invention also provides other embodiments:
