Description
Technical field
The present invention relates to air-conditioning, especially a kind of air-conditioning that has anti-liquid hammer adjusting device.
Background technology
In general, air conditioner is arranged on the wall of the interior spaces such as office or family, the refrigerating/heating household electrical appliance that room air is freezed or heats.Air conditioner constitutes the refrigerating/heating circulation by compressor, condenser, expansion valve, evaporimeter.
Air conditioner constitutes with the indoor set that is arranged on interior of building by being arranged on outdoor off-premises station.Off-premises station is provided with condenser (outdoor heat converter) and compressor, and indoor set is provided with evaporimeter (indoor heat converter).
The kind of air conditioner roughly is divided into the integrated air conditioner of off-premises station and the indoor type-dividing conditioner that is separated from each other and off-premises station and an integral body of indoor set formation.
Be example with the window air conditioner below, air-conditioning described:
As shown in Figure 1, the structure of the window air conditioner of prior art design is: chassis 1 constitutes the bottom surface of air-conditioning, and the place ahead, indoor of 1 is provided with front panel 3 on the chassis.
The lower end of panel 3 has formed the air suction structure 3i that draws room air in front, and the upper end is provided with the air discharge grille 3e of the air after indoor discharge heat exchange.And, on air discharge grille 3e, be provided with several steam vents 3e` to indoor discharge air.
Simultaneously, be provided with suction grille 4, and on suction grille 4, be provided with the suction hole 4` of several absorbing air, and between suction grille 4 and air suction structure 3i, be provided with filter (not expression among the figure) in the place ahead of air suction structure 3i.
The inboard of panel 3 is provided with evaporimeter 5 in front.In evaporimeter 5, working fluid that it is inner and the air of drawing through air suction structure 3i carry out heat exchange.Evaporimeter 5 specifically is arranged on the baffle plate 7.
The rear end of said The One On The Chassis evaporimeter 5 is provided with baffle plate 7.The effect of baffle plate 7 is that whole air-conditioning is divided into indoor section and outdoor section.Thus, under the effect of baffle plate 7, can not produce air between indoor section and the outdoor section and flow.Be provided with the brace that is connected with following guard shield 18 in the upper end of baffle plate 7.
In the set inside of baffle plate 7 volute 9.On volute 9, be provided with by certain curvature from the crooked guide face 9g of a certain side direction opposite side.
In the front of volute 9, be provided with orifice plate 11 on the promptly corresponding position with evaporimeter 5.The air that has passed through evaporimeter 5 is guided to the throttle orifice 12 on the following indoor fan 13 being provided with on the orifice plate 11.And, be provided with the air that forms integral body with it in the upper end of orifice plate 11 and guide to the exhaust guide 11e on the air discharge grille 3e after the heat exchange.
Simultaneously, in the set inside of volute 9 indoor fan 13, make room air pass through air suction structure 3i and evaporimeter 5 and throttle orifice 12 and flow.Indoor fan 13 is discharged air through throttle orifice 12 absorbing air and from circumferencial direction, and the air of discharging is directed to exhaust guide 11e along guide face 9g.
More than the structure of explanation is the indoor section of window air conditioner, down in the face of being described by the structure of the outdoor section of baffle plate 7 divisions:
On the outside of baffle plate 7, be provided with the motor 15 of drive chamber's internal fan 13 and outdoor fan 17.The rotating shaft of said motor 15 outstanding towards relatively.Wherein the rotating shaft of a certain side runs through the center that said baffle plate 7 extends to volute 9, turning cell internal fan 13.
In motor 15 outside rotating shafts, be provided with outdoor fan 17.Outdoor fan 17 makes it carry out heat exchange through following condenser 19 behind the outdoor absorption outside air of air-conditioning.On outdoor fan 17, be provided with the water ring 17r that connects blade end.
On chassis 1, be provided with the guard shield 18 of the air-flow of guiding outdoor fan 17 generations.On guard shield 18, be provided with along with the rotation of the outdoor fan 17 of condenser 19 intercommunications and produce the through hole 18` of air-flow.The outside air that guard shield 18 guiding outdoor fans are seen off, and air is flowed on whole condenser 19.Guard shield 18 is arranged at the two ends of condenser 19, and is connected with said baffle plate through brace.
On the outside on chassis 1, be provided with guard shield 18 towards relative condenser 19.The effect of condenser 19 is to make the outside air of absorption and inner working fluid carry out heat exchange.And, on the The One On The Chassis position that is equivalent between baffle plate 7 and the guard shield 18, be provided with the compressor 20 in the air handling system.
At last, utilize as above each element of the formation air-conditioning of layout of shell 21 sealings, so that be isolated from the outside.Such shell 21 has constituted the outward appearance of air-conditioning.
The indoor section of the air-conditioning that as above constitutes is arranged to be needed to regulate in the indoor environment of air, and that outdoor section is arranged at is outdoor.
For split-type air conditioner, its operation principle is the same, no longer narration.The compressor of air-conditioning is divided into constant speed compressor and frequency-changeable compressor.Air-conditioning for using constant speed compressor can cause the evaporation of refrigerant incomplete when low load operation, has liquid refrigerant to get in the compressor easily, causes the Wet Compression of compressor, can cause liquid hammer when serious, damages compressor.
Specifically, because unevaporated refrigerant gets into compressor through low pressure line, make liquid refrigerants get into compressor; When a large amount of refrigerant liquids sucks compressor cylinder along with steam; Because the impact of liquid and incompressible can damage suction valve chip, and do not discharge rapidly after getting into cylinder in exhaust process; Be compressed during near top dead centre and the high hydraulic pressure of moment that produces at piston, liquid hammer takes place.Liquid hammer can cause the damage of compressor stressed member in very short time, thereby compressor is caused fatal damage.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of compressor that prevents to produce the air-conditioning that has anti-liquid hammer adjusting device of liquid hammer.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of air-conditioning that has anti-liquid hammer adjusting device; Comprise compressor, fluid reservoir, evaporimeter, condenser, indoor fan, outdoor fan; Between the escape pipe of the air inlet pipe of constant speed compressor and compressor, increase by one and make the anti-liquid hammer adjusting device that to carry out heat exchange between air inlet pipe and the escape pipe; The air inlet and the gas outlet of evaporimeter are provided with temperature detector, and when the air inlet temperature of temperature detector sensing evaporator was higher than the gas outlet, anti-liquid hammer adjusting device started.
Said air inlet pipe is positioned at the top of fluid reservoir, and escape pipe is positioned at the top of compressor.
Said anti-liquid hammer adjusting device comprises the shell of tubular; Be formed with air inlet pipe groove and escape pipe groove that the air inlet pipe that makes compressor respectively and escape pipe pass on the shell of tubular; In the enclosure; The inboard of air inlet pipe groove and escape pipe groove is formed with a plurality of angle-inserting type fins; When air inlet pipe and escape pipe were inserted in air inlet pipe groove and the escape pipe groove, the angle-inserting type fin closely contacted with escape pipe with air inlet pipe, was provided with the fan that the enclosure air is flowed in the shell between air inlet pipe groove and escape pipe groove.
Said fan is an aerofoil fan, is installed on the support that enclosure vertically is set.
The said shell side of being tube.
