It should be noted that, when the regulating device 1 is disposed downstream of the detecting device 2, the flow rate of the regulating device 1 may be measured, but the flow rate must be accurately fed back after the refrigerant flow in the entire refrigeration system is in stable equilibrium. Preferably, the regulating device 1 is arranged upstream of the detecting device 2, in the flow direction of the refrigerant inside the branch conduit 4.

Preferably, as shown in fig. 1 and 2, the detecting means 2 is provided on the connecting tube 13.
Exemplarily, the detecting device 2 is disposed on the connecting pipe 13 and near one side of the adjusting device 1, that is, the detecting device 2 and the adjusting device 1 are taken as an integral component, and can be conveniently mounted or dismounted with the branch pipe 4, thereby saving the mounting and dismounting steps between the detecting device 2 and the adjusting device 1.
It should be noted that the detecting device 2 can also be installed on a separate pipeline, and the separate pipeline is connected to the connecting pipe 13, and such adjustment and change of the specific installation position of the detecting device 2 do not depart from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

In a preferred case, as shown in fig. 1 and 2, the inner diameters of the connection pipes 13 are the same, and the detection device 2 includes a flow rate sensor 22, the flow rate sensor 22 being disposed inside the connection pipe 13.

When the refrigerant passes through the flow dividing device at a high speed, that is, when the flow rate of the refrigerant is greater than a specific flow rate, the refrigerant is uniformly distributed in the branch pipes 4, and since the inner diameters of the connecting pipes 13 are the same, the amount of the refrigerant flowing through the connecting pipes 13 per unit time can be fed back according to the flow rate of the refrigerant, when the flow rate of the refrigerant is greater than the specific flow rate, the flow rate of the refrigerant is detected by the flow rate sensor 22, the flow rate of the refrigerant in each branch pipe 4 is controlled by the adjusting device 1, and the flow rate of the refrigerant in each branch pipe 4 can be kept relatively balanced.

It should be noted that, when the refrigerant passes through the flow dividing device at a low speed, that is, the flow rate of the refrigerant is not greater than a specific flow rate, the flow state of the refrigerant is affected due to the internal resistance problem of the evaporator pipeline, or the placement problem of the evaporator pipeline, for example, the evaporator is not placed correctly or obliquely, when the flow rate of the refrigerant is in the low speed state, in the above situation, the refrigerant is not uniformly distributed in the branch pipes 4, at this time, the flow rate of the refrigerant detected by the flow rate sensor 22 cannot accurately feed back the flow rate of the refrigerant flowing through the connecting pipe 13, so that the temperature and the air pressure of the refrigerant in the connecting pipe 13 are obtained, and the accuracy of the flow rate of the refrigerant in the connecting pipe 13 can be ensured.
According to the ideal gas state equation, the formula is as follows:
wherein the parameter p represents pressure; the parameter V represents the volume; the parameter M represents mass; the parameter R is a universal gas constant; the parameter mu is the molar mass; the parameter T represents the temperature.
The ideal gas state equation is simplified as follows:
because the inner diameter of each connecting pipe 13 is set to be the same, the volume parameter V can be replaced by the flow velocity of the refrigerant, in this way, in the same time, only three parameters of the pressure, the temperature and the flow velocity of the refrigerant in the connecting pipe 13 need to be obtained, the ratio of the product of the pressure parameter p and the flow velocity of the refrigerant and the temperature parameter T is recorded as a flow state value, the flow size of the refrigerant in each branch pipe 4 is controlled through the adjusting device 1, the flow state values fed back by the detecting devices 2 of each branch pipe 4 are kept to be the same, and the flow of the refrigerant in each branch pipe 4 can be kept to be relatively balanced.
In another preferred case, the detection device 2 is a flow sensor (not shown in the figures).
Illustratively, the access detection device 2 on each branch pipe 4 of the flow dividing device is a flow sensor (not shown in the figure).
A flow sensor is a detecting instrument for detecting a flow parameter of a medium such as a liquid or a gas, converting the flow parameter into a signal of another form, and outputting the signal. The flow rate of the refrigerant in the branch pipe 4 can be directly obtained by the flow rate sensor.
It should be noted that, by comparing the flow rate values of the refrigerants in the branch pipes 4 of the branching device and controlling the flow rate of the refrigerants in the branch pipes 4 by adjusting the direct adjusting device 1, the flow rate sensor can directly feed back whether the flow rates of the refrigerants in the branch pipes 4 of the branching device are balanced.
It should be noted that the adjusting device 1 may be provided as an electronic expansion valve or an electrically operated valve (not shown).
Illustratively, the regulating device 1 is directly connected to each branch pipe 4 of the flow dividing device by using an existing electronic expansion valve or electric valve (not shown).
It should be noted that the electronic expansion valve or the electrically operated valve may be connected to a controller of the refrigeration system, and the state parameters of the refrigerant in each branch pipe 4 are detected by feedback from the detection device 2, and the electronic expansion valve or the electrically operated valve is automatically calculated and adjusted by the controller, so that the flow rate of the refrigerant in each branch pipe 4 is kept relatively balanced, manual operation is not required, and the automatic control effect of the flow dividing device is improved.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the utility model, and the technical scheme after the changes or substitutions can fall into the protection scope of the utility model.
