The utility model provides a kind of debugging apparatus of air-conditioner restricting element.
With reference to Fig. 1 and 2, Fig. 1 is the module diagram of the debugging apparatus of the utility model air-conditioner restricting element; Fig. 2 is the structural representation of the debugging apparatus of the utility model air-conditioner restricting element.The debugging apparatus (hereinafter to be referred as debugging apparatus) of a kind of air-conditioner restricting element that the present embodiment provides, comprise the first switch module K1 being connected with condenser 1, the second switch assembly K2 being connected with evaporimeter 2, for storing the refrigerant storage assembly 3 of refrigerant, and reclaim assembly 4 for the gas of gas recovery.Wherein, at least one restricting element 5 that removably connects between the first switch module K1 and second switch assembly K2.The first end of restricting element 5 is connected with the first end of the first switch module K1, and the second end of restricting element 5 is connected with the first end of second switch assembly K2.The second end of the first switch module K1 is connected with condenser 1, and the second end of second switch assembly K2 is connected with evaporimeter 2.The delivery outlet of refrigerant storage assembly 3 is connected with the first end of restricting element 5.Gas reclaims the input port of assembly 4 and the second end of restricting element 5 is connected.
This first switch module K1 has played switch.When debugging apparatus is connected and starts air conditioner debugging with condenser 1, the first switch module K1 opens, and debugging apparatus is communicated with condenser 1.When stopping air conditioner debugging, the first switch module K1 closes, and debugging apparatus is not communicated with condenser 1.This first switch module K1 can be any device with on-off action, for example triple valve or knob valve.It should be noted that for fear of secondary refrigerant leakage in air, the first switch module K1 and condenser 1 and throttling arrangement are all tightly connected.In like manner, second switch assembly K2 is identical with the first switch module K1 role in debugging apparatus, please refer to the first switch module K1 and understands second switch assembly K2, does not repeat them here.
Refrigerant storage assembly 3 is for storing refrigerant.This debugging apparatus to the emptying means of restricting element 5 is: in restricting element 5, fill liquid refrigerant, by liquid refrigerant, the air in restricting element 5 is squeezed to gas and reclaimed in assembly 4.What therefore, refrigerant storage assembly 3 stored is the refrigerant of liquid.It should be noted that refrigerant storage assembly 3 comprises delivery outlet.The refrigerant of liquid is exported by the delivery outlet of refrigerant storage assembly 3.The delivery outlet of refrigerant storage assembly 3, the first switch module K1 and restricting element 5 connect by three-way pipe, thereby realize three, are communicated with.
Gas reclaims assembly 4 for reclaiming air and the refrigerant being emitted by restricting element 5.For the gas in restricting element 5 can be easily discharged in gas recovery assembly 4, the pressure of gas recovery assembly 4 should be less than the pressure of restricting element 5.Preferably, emptying front gas reclaims in assembly 4 in vacuum state.
Debugging apparatus can connect one or more restricting elements 5, and this restricting element 5 can be capillary 5a or electric expansion valve 5b.A plurality of restricting elements 5 are set in debugging apparatus, have avoided being dismounted for multiple times back and forth, can convenient debugging operations.Restricting element 5 is located at the position between the first switch module K1 and second switch assembly K2.
In the present embodiment, debugging apparatus two restricting elements 5 that removably connect, these two restricting elements 5 are arranged in parallel, and it is capillary 5a that the present embodiment preferably arranges one of them restricting element 5, and another is electric expansion valve 5b.Should be understood that, according to actual needs, two restricting elements 5 can be capillary 5a simultaneously, can be also electric expansion valve 5b simultaneously.The first switch module K1 and second switch assembly K2 are triple valve.For convenient debugging, the first knob valve is also set between the first switch module K1 and restricting element 5, the second knob valve is also set between second switch assembly K2 and restricting element 5.When air-conditioner need to carry out matching and debugging, first close the first switch module K1, second switch assembly K2, the first knob valve and the second knob valve, and close the delivery outlet of refrigerant storage assembly 3 and the input port that gas reclaims assembly 4.Again capillary 5a and electric expansion valve 5b are installed on to the position between the first switch module K1 and second switch assembly K2.After installing, to capillary 5a, carry out emptying.When emptying, first open the first knob valve and the second knob valve, then that the delivery outlet of refrigerant storage assembly 3 is crack, then open the input port that gas reclaims assembly 4.It is inner that liquid refrigerants in refrigerant storage assembly 3 will be filled to capillary 5a, and the air in capillary 5a is squeezed to gas and reclaimed in assembly 4.Air in capillary 5a is discharged to gas and reclaims after assembly 4, closes successively gas and reclaims the input port of assembly 4 and the delivery outlet of refrigerant storage assembly 3, then open the first switch module K1 and second switch assembly K2, and enter air-conditioner matching and debugging state.When needs carry out matching and debugging to electric expansion valve 5b, similarly, carry out emptying to electric expansion valve 5b.The evacuation step of electric expansion valve 5b is identical with the evacuation step principle of above-mentioned capillary 5a, please refer to above-mentioned steps and understands.Do not repeat them here.
The debugging apparatus of the air-conditioner restricting element that the utility model provides has mainly increased refrigerant storage assembly 3 and gas reclaims assembly 4.When air-conditioner model machine is changed after restricting element 5, this debugging apparatus can fill liquid refrigerants to restricting element 5 by refrigerant storage assembly 3.During liquid refrigerants squeezes the air in restricting element 5 to reclaim assembly 4 to gas, thereby realized emptying to restricting element 5.And gas reclaims 4 pairs of air of assembly and refrigerant reclaims, thereby avoided refrigerant pollution air.On the other hand, this debugging apparatus squeezes air by refrigerant, and these refrigerants are not from air-conditioner prototyping system, but from the refrigerant storage assembly 3 of extra increase, therefore make in whole evacuation procedure, can not reduce the coolant quantity of air-conditioner model machine itself, thereby can guarantee that air-conditioner model machine can good debug.In addition, in the process of air-conditioner prototype debug, coolant quantity is not enough, and refrigerant storage assembly 3 can add refrigerant in air-conditioner model machine, to guarantee that air-conditioner can good debug.
