Below with reference to Fig. 1-Fig. 4, the air-conditioning system 100 according to the utility model embodiment is described.
As Figure 1-Figure 4, air-conditioning system 100 according to the utility model embodiment comprises: compressor 1, outdoor heat exchanger 2, first throttle device 3, pressure pan 4, indoor heat exchanger 5, the second throttling arrangement 6, the first temperature sensor 7, the second temperature sensor 8 and controller (scheming not shown).
The entrance of outdoor heat exchanger 2 is connected to the outlet of compressor 1, the entrance of first throttle device 3 is connected to the outlet of outdoor heat exchanger 2, the entrance of pressure pan 4 is connected to the outlet of first throttle device 3, and the outlet that the entrance of indoor heat exchanger 5 is connected to the outlet of pressure pan 4 and indoor heat exchanger 5 is connected to the import of compressor 1.The second end apart from its bottom preset distance place and the second throttling arrangement 6 that the first end of the second throttling arrangement 6 is connected to pressure pan 4 sidewalls is connected to the entrance of compressor 1.
The first temperature sensor 7 and the second temperature sensor 8 are placed in respectively the junction of the second throttling arrangement 6 and pressure pan 4 sidewalls and compressor 1 entrance, the first temperature sensor 7 is placed in the junction of the second throttling arrangement 6 and pressure pan 4 sidewalls, and the second temperature sensor 8 is placed in the junction of the second throttling arrangement 6 and compressor 1 entrance.
Wherein, the first temperature sensor 7 and the second temperature sensor 8 are connected to respectively controller with the difference of calculating the first temperature sensor 7 and the second temperature sensor 8 measured temperatures by controller and compare with predetermined value.
Here it will be appreciated that, when operating personnel fill refrigerant, be full of refrigerant in pipeline, outdoor heat exchanger 2 and the indoor heat exchanger 5 of system after, unnecessary refrigerant will temporarily be stored in pressure pan 4, along with continuing to fill refrigerant, the liquid level in pressure pan 4 can rise gradually.When refrigerant reaches a certain default liquid level in pressure pan 4, at this moment the charging amount of refrigerant in system reached zone of reasonableness, and now operating personnel should stop continuing to fill.Wherein should can carry out by experiment concrete calculating according to concrete air-conditioning system 100 by those skilled in the art by default liquid level.
Air-conditioning system 100 according to the utility model embodiment, because the first temperature sensor 7 is placed in the junction of the second throttling arrangement 6 and pressure pan 4 sidewalls, the first temperature sensor 7 is placed in apart from the preset distance place of pressure pan 4 bottoms, while when refrigerant, reaching the position at these the first temperature sensor 7 places in pressure pan 4, the first temperature sensor 7 will detect the temperature of the refrigerant in pressure pan 4, difference and predetermined value by the measured temperature by the first temperature sensor 7 and the second temperature sensor 8 compares again, just can judge refrigerant whether the default liquid level in pressure pan 4 whether reached this position, and then whether the coolant injection that can judge system has reached zone of reasonableness.
Particularly, close according to the logic judgement of a judgement coolant injection amount of the air-conditioning system 100 of the utility model embodiment and be:
When the difference of the first temperature sensor 7 and the second temperature sensor 8 measured temperatures is more than or equal to this predetermined value, the coolant injection amount of air-conditioning system 100 has reached zone of reasonableness, and operating personnel can stop filling refrigerant.When the difference of the first temperature sensor 7 and the second temperature sensor 8 measured temperatures is less than this predetermined value, the refrigerant in air-conditioning system 100 does not also reach reasonable amount, and operating personnel can continue to fill refrigerant.
By the second throttling arrangement 6 being set between pressure pan 4 and compressor 1 entrance to be communicated with the entrance of pressure pan 4 and compressor 1, can make thus the more accurate of the difference of the first temperature sensor 7 and the second temperature sensor 8 measured temperatures and predetermined value.
Therefore according to the air-conditioning system 100 of the utility model embodiment, by the first temperature sensor 7 and the second temperature sensor 8 are set, and difference and predetermined value by the first temperature sensor 7 and the second temperature sensor 8 measured temperatures compare, by the detection to pressure pan 4 places and compressor 1 porch temperature, statistics and judgement, judge the charging amount of these air-conditioning system 100 refrigerants, thereby guarantee that the refrigerant of this air-conditioning system 100 can be all the time in rational scope.
That is to say, the air-conditioning system 100 of the utility model embodiment be a kind of simple in structure, control the air-conditioning system with refrigerant automatic detection function 100 accurate, easy and simple to handle, with low cost, by this air-conditioning system 100, both can judge accurately that system coolant injection amount whether in rational scope, guaranteed the good result that this air-conditioning system 100 heats, freezes; The puzzlement of technical solution personnel aspect the judgement of coolant injection amount effectively again, for refrigeration industry provides reference value to more perfect, more humane future development.
In embodiment more of the present utility model, operating personnel can utilize as required this controller to start or turn-off the refrigerant automatic detection function.For example, when operating personnel carry out coolant injection, can start this refrigerant automatic detection function by controller, carry out the filled work of refrigerant according to the refrigerant automatic detection function as operating personnel, after making coolant quantity reach in zone of reasonableness, when operating personnel can turn-off this refrigerant automatic detection function by controller, with the time air-conditioning system 100 use more flexible.
Particularly, can on air-conditioning system 100, control button be set, can press this control button to start the refrigerant automatic detection function when operating personnel carry out coolant injection, after completing the filling of refrigerant, operating personnel can press this control button again to turn-off the refrigerant automatic detection function.
In an embodiment of the present utility model, air-conditioning system 100 also can comprise suggestion device (scheming not shown).Suggestion device is connected with controller after comparing with the difference according to the first temperature sensor 7 and the second temperature sensor 8 measured temperatures and predetermined value and is pointed out.Thus can by this suggestion device more easily the coolant injection amount of alert air-conditioning system 100 whether meet the requirements.
This suggestion device can be the various forms such as sound, light, electronics, and the difference that can make thus air-conditioning system 100 adapt to various reality requires and different physical conditions.
In a specific embodiment of the present utility model, the lamp that suggestion device is variable color.Particularly, when the difference of the first temperature sensor 7 and the second temperature sensor 8 measured temperatures is less than this predetermined value, the refrigerant in air-conditioning system 100 does not also reach reasonable amount, and lamp prompts for a kind of color, for example green, can continue to fill refrigerant with this alert; When the difference of the first temperature sensor 7 and the second temperature sensor 8 measured temperatures is more than or equal to predetermined value, the coolant injection amount of air-conditioning system 100 has reached zone of reasonableness, lamp can prompt for another color, for example red, with this alert, can stop filling refrigerant.
