Description
Technical field
The invention belongs to vehicle air conditioning field, more particularly to a kind of device of the refrigerant deterioration of real-time detection air-conditioning.
Background technology
In use for some time, the pollutants such as impurity, vapor can be mixed into air-conditioning refrigerant vehicle air conditioner, be made
Into the deterioration of refrigerant, and then cause the decline of vehicle refrigerating efficiency and the raising of energy consumption.Tackle the usual way of the problem, one
It is the refrigerant replaced using dedicated refrigerant charging machine in air-conditioning system, and common plunger pump type or compressor-type filling
The filling precision of machine is low, is difficult to control, and equipment cost is higher, and filling process is complicated, it is often more important that, this replacement refrigerant
Method only can wait until refrigerant deterioration to a certain extent after can just implement, can not inhibit or slow down in real time before this system
The process of cryogen deterioration, it is clear that deleterious effect can all be brought by replacing refrigerant too early or too late.And when should replace system
Cryogen is typically only capable to roughly be inaccurate by air conditioning usage time.
The content of the invention
In order to which the opportunity for replacing air-conditioning refrigerant is given to provide accurate foundation, the present invention provides a kind of detection air-conditionings in real time
Refrigerant deterioration device, technical scheme is as follows, including：
The air-conditioning includes compressor, at least one heat exchanger and the connection for forming refrigerant flow cycle
Pipeline；It is characterized in that, described device includes：
The first detection pipe positioned at the downstream side of refrigerant flow cycle of compressor is closely arranged on, is used in real time
Detection refrigerant flows through the degradation after compressor；Closely it is arranged on being located under refrigerant flow cycle for heat exchanger
The second detection pipe of side is swum, is used to detecting refrigerant in real time and flows through the degradation after heat exchanger；First, second inspection
The bottom of the inside of test tube has ultrasonic transmitter-receiver, and top is ultrasonic reflections face；
Controller is connected respectively with the ultrasonic transmitter-receiver signal in first, second detection pipe and signal compressor,
Controller judges to freeze in circuit according to the tach signal of compressor and the ultrasonic signal from ultrasonic transmitter-receiver perception
The degradation of agent：
When air-conditioning system is run, refrigerant flows into through connecting pipe and successively full of first, second detection pipe；Work as compressor
Rotating speed when undergoing mutation, since the refrigerant in detection pipe can form turbulent flow, ultrasonic transmitter-receiver record at this time it is actual when
Length can not accurately reflect the degradation of refrigerant, therefore controller control ultrasonic transmitter-receiver does not work, until compression
The stabilization of speed of machine；
During the stabilization of speed of compressor, the ultrasonic transmitter-receiver in detection pipe sends ultrasonic wave to ultrasonic reflections face and connects
The ultrasonic wave that reflects is received, ultrasonic signal is recorded from being issued to and receives actual duration used, controller is by the reality
Border duration calculates the difference of the two compared with ultrasonic signal under standard state is from the standard duration being issued to used in reception
Value, when two differences are respectively less than first threshold, controller then judges that the refrigerant does not deteriorate；When in two differences
It is at least one between first threshold and second threshold, controller then judges that the refrigerant is being flowed through corresponding to the difference
It is deteriorated during the upstream of detection pipe；When two differences are all higher than second threshold, controller then judges that the refrigerant occurs
It deteriorates and issues the user with the prompt message for replacing refrigerant.
The obvious first threshold<Second threshold.
The standard state refers to：Working condition when being used for the first time after air-conditioning system has replaced refrigerant.
The deterioration process of refrigerant can be simultaneously and dynamically detected by the present invention, the opportunity to replace refrigerant provides
Accurate foundation.
Description of the drawings
Fig. 1 shows the schematic diagram of the device of the invention.
Specific embodiment
Below in conjunction with specific embodiment, detailed description of the present invention detects the device of the refrigerant deterioration of air-conditioning in real time.
As shown in Figure 1, air-conditioning system includes compressor 1, at least one heat exchanger 3 and for forming refrigerant stream
The connecting pipe in logical circuit；Described device includes：
The first detection pipe 2 positioned at the downstream side of refrigerant flow cycle of compressor 1 is closely arranged on, is used for reality
When detection refrigerant flow through the degradation after compressor 1；Closely be arranged on heat exchanger 3 is located at refrigerant flow cycle
Downstream side the second detection pipe 4, be used to detecting refrigerant in real time and flow through the degradation after heat exchanger 3；Described first
The bottom of the inside of detection pipe 2 has ultrasonic transmitter-receiver 2.1, and top is ultrasonic reflections face 2.2；Second detection pipe 4
Inside bottom have ultrasonic transmitter-receiver 4.1, top be ultrasonic reflections face 4.2
Respectively with compressor 1, ultrasonic transmitter-receiver signal 2.1,4.1 signals in first, second detection pipe connect controller 5
It connects, and according to the tach signal of compressor 1 and the ultrasonic signal from ultrasonic transmitter-receiver perception, judges to freeze in circuit
The degradation of agent：
When air-conditioning system is run, refrigerant flows into through connecting pipe and successively full of first, second detection pipe；Work as compressor
Rotating speed when undergoing mutation, since the refrigerant in detection pipe can form turbulent flow, ultrasonic transmitter-receiver record at this time it is actual when
Length can not accurately reflect the degradation of refrigerant, therefore controller control ultrasonic transmitter-receiver does not work, until compression
The stabilization of speed of machine；
During the stabilization of speed of compressor, the ultrasonic transmitter-receiver in detection pipe sends ultrasonic wave to ultrasonic reflections face and connects
The ultrasonic wave that reflects is received, ultrasonic signal is recorded from being issued to and receives actual duration used, controller is by the reality
Border duration calculates the difference of the two compared with ultrasonic signal under standard state is from the standard duration being issued to used in reception
Value, when two differences are respectively less than first threshold, controller then judges that the refrigerant does not deteriorate；When in two differences
It is at least one between first threshold and second threshold, controller then judges that the refrigerant is being flowed through corresponding to the difference
It is deteriorated during the upstream of detection pipe；When two differences are all higher than second threshold, controller then judges that the refrigerant occurs
It deteriorates and issues the user with the prompt message for replacing refrigerant.
