Abstract
The utility model relates to an easy continuous starting air conditioner which is characterized in that a uninstall protection device which is composed of an electromagnetic valve and a capillary pipe is arranged between a high-pressure pipeline on the air exhaust end of a compressor and a low-pressure pipeline on the air suction end of the compressor of the existing air conditioner body. A relay is additionally arranged on the existing automatic control device, so the electromagnetic valve is attracted to be in an open state by the relay within the 20 seconds before the starting of the compressor, within the one minute after the starting or the three minutes after the stop of the compressor; the utility model can ensure that after air conditioners are closed, the air conditioners, especially air conditioners with large refrigerating output, can be quickly started once more, so the interval time of two-time starting operation is reduced, and the reliability of the starting operation is increased.
Description
The utility model relates to the air-conditioner of startup continuously that is easy to that can make the rapid equalizing pressure of refrigerating plant after compressor shutdown.
Existing air conditioner, the especially Air Conditioner of refrigerating capacity more than 7 kilowatts, the pressure after compressor shutdown in the refrigeration system is difficult to reach rapidly balance, causes compressor to start difficulty once more, and starting current is big, impacts bigger to electrical network; At present, generally take to allow just to allow more than 3-5 minute to start once more after the compressor shutdown, but this still can't thoroughly solve the pressure balance problem, can not guarantee the continuous startup of short time and can both start smoothly at every turn.
The object of the present invention is to provide a kind of air-conditioner of startup continuously that is easy to,, reduce the blanking time of twice startup, increase the reliability of startup to solve the rapid equalizing pressure of energy after compressor shutdown.
The utility model is the uninstall protection device of being made up of magnetic valve and capillary in the input of compressor and output cross-over connection one; and on automaton, increase again one control this magnetic valve relay; be that the relief circuit that a magnetic valve and capillary are formed is set between the low pressure pipeline of the pressure piping of compressor air-discharging end and compressor air suction end specifically; and above-mentioned magnetic valve is controlled by the relay of setting up on the existing automaton; making it can be at compressor start preceding 20 seconds, starts in 3 minutes in back 1 minute or after the compressor shutdown adhesive magnetic valve and is in open mode and gets final product.
Obvious magnetic valve of the present utility model still was in open mode in back one minute in startup, will reduce the load of initial start stage, and non-reason load is shut down greatly so that can reach higher rotation speed rapidly after guaranteeing to start; In 3 minutes, magnetic valve still is in opening after the compressor shutdown, will make the rapid balance of its high-low pressure after the compressor shutdown, is convenient to compressor and starts once more; And with effect capillaceous that magnetic valve is connected in series mutually be the buffering magnetic valve when after compressor shutdown, directly opening high-low pressure gang up the impact of generation, the gas flow noise that produces to reduce high-low pressure directly to be communicated with.
Further specify the utility model below in conjunction with drawings and Examples.
The utility model comprises by compressor 1 and is attached thereto logical pressure switch 2, oil eliminator 3 and the oil return capillary 12 of suction side, the compression set that gas-liquid separator 11 is formed, the condensing unit of forming by outdoor heat exchanger 4, outdoor fan 5, the vaporising device of forming by indoor heat exchanger 9 and indoor fan 10, and the filter 6 that is used for the throttling step-down between the heat exchanger of indoor and outdoor, electric expansion valve 7, reservoir 8, two logical stop valves 15 and three-way cut-off valve 16 and corresponding pipeline and automaton.It is characterized in that it also comprises the uninstall protection device that a magnetic valve 13 and capillary 14 are connected to form, be provided with or cross-over connection between the low pressure pipeline B of the pressure piping A of compressor 1 exhaust end and suction end.
The relief circuit that above-mentioned magnetic valve 13 and capillary 14 are connected to form, an end of its magnetic valve 13 can link to each other with oil eliminator 3, and the other end of capillary 14 is to link to each other with the arrival end of gas-liquid separator 11, as shown in the figure.
Above-mentioned magnetic valve 13 should be selected the closed type magnetic valve of circulation diameter more than Φ 2mm for use.Capillary 14 should select diameter at Φ 1.0-2.0mm; length range is between 300-2000mm; the annular of general coiled Φ 30-80mm, to reduce bulk, capillary parameter selection principle is mainly exceeded with the criteria for noise that compressor produces when magnetic valve 13 is opened when shutting down.Above-mentioned uninstall protection device; be not difficult to rely on a relay setting up on the existing automaton preceding 20 seconds at compressor start; the adhesive magnetic valve is in open mode in 3 minutes in 1 minute after the startup or after the compressor shutdown; can guarantee that the air-conditioner air-conditioner that particularly refrigerating capacity is big can start rapidly once more after shutdown; thereby reduce the blanking time of twice startup, increase the reliability that starts.
