Fig. 6 is a flowchart of an alternative control method of a perfusion apparatus according to an embodiment of the present invention, where as shown in fig. 6, the control flowchart of a dual-gun four-system coolant perfusion apparatus system, as shown in fig. 6, a perfusion gun a and a perfusion gun B communicate with coolant flow paths where R22, R134a, R32, and R410a are located, respectively, and can close a stop valve 2 of the flow path where R22 is located, a stop valve 1 of the flow path where R134a is located, a stop valve 4 of the flow path where R32 is located, and a stop valve 3 of the flow path where R410A is located; then, discharging the refrigerants; then, the stop valve 1 of the flow path where the R22 is located, the stop valve 2 of the flow path where the R134a is located, the stop valve 3 of the flow path where the R32 is located and the stop valve 4 of the flow path where the R410A is located are opened, the refrigerant is discharged, and filling is started; respectively detecting whether the sensor 2, the sensor 1, the sensor 4 and the sensor 3 have readings, and if so, alarming and stopping; otherwise, whether the sensor 1, the sensor 2, the sensor 3 and the sensor 4 have readings is detected, if not, the machine is stopped by alarming, otherwise, the machine is filled.
In the embodiment of the present invention, the perfusion gun B is described as an example.
Wherein, the hardware part can be: the main loop is provided with a flowmeter (flowmeter B) for measuring the weight of the refrigerant in the filling process of the filling gun) and a stop valve (stop valve B for cutting off the refrigerant when the filling gun is overhauled); the main loop is connected in series with a parallel loop, and the parallel loop has two paths which respectively correspond to two different refrigerants, namely R32 and R410A; in two loops of the parallel loop, a loop with lower pressure, namely an R410A loop, is connected with a check valve in series (the check valve B prevents R32 refrigerant from being connected into an R410A pipeline by pressure difference when a stop valve 3 and a stop valve 4 are opened simultaneously, so that the refrigerant is mixed); the parallel loop and 2 paths are all provided with 1 stop valve, a sensor (flow sensor) and a joint respectively.
Specifically, when the perfusion R410A refrigerant is produced and needs to be switched to the perfusion R32 refrigerant, as shown in fig. 3 and 4, the operation is as follows: 1) adjusting the type of refrigerant R410A of the interface of the filling machine to be R32; 2) closing the stop valve 4; 3) butting the filling gun B to a joint of a refrigerant recovery pipeline, setting a direct filling mode of the filling machine, pressing a filling button of a filling gun head, and discharging R410A refrigerant of a pipeline between the stop valve 4 and the filling gun B to the recovery pipeline; 4) opening the stop valve 3, and repeating the step 2, wherein the step is used for cleaning the filling machine system; 5) connecting the filling gun B to a quick connector or a corner valve of an air conditioner product; 6) pressing a perfusion button on the perfusion gun B to start perfusion; 7) and respectively reading the numerical values of the sensor 3 and the sensor 4 in the perfusion process, and judging according to the following sequence: step 1, judging whether a sensor 4 has a numerical value, if so, giving an alarm to prompt, and stopping filling; if no value exists, entering the step 2; step 2, judging whether the sensor 3 has a numerical value, if not, alarming and prompting, and stopping filling; if so, the perfusion is continued to be completed.
By the control method of the filling machine provided by the embodiment of the invention, the capacity of three refrigerant (for example, R22/R32/R410A) products is basically met in the current air-conditioning production line, the cost can be saved (the number of the filling machines is saved), 2 filling machines which are matched with a single gun to output a single refrigerant are needed for one production line to solve the refrigerant type filling error, and only 1 filling machine which is matched with a double gun and a four system is needed for the double gun, namely 1 filling machine is saved; the problem of refrigerant type perfusion error can be effectively solved: in the case where 1 filling machine is selected for both the "two-gun two-system" and the "two-gun four-system". Both cases require a filling machine 1 in which the gun can selectively output one of 2 refrigerants, such as R32 and R410A refrigerants share a common gun. The "dual-gun dual-system" filling machine has a risk of wrong filling of refrigerant types during refrigerant switching, such as: R410A is used in production, the next order is switched to use R32, a refrigerant pipeline butted to a filling machine is not switched to R32, only the refrigerant selection of a filling interface of the filling machine is changed to R32, and thus refrigerant type filling errors occur, and the problem is hidden and is not easy to find; the above problems do not occur in the "two-gun four-system" perfusion apparatus, and the embodiments are specifically described.
