The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of air-conditioning servicing unit.
With reference to Fig. 1, Fig. 1 is the structural representation of the utility model air-conditioning servicing unit the first embodiment.
In the utility model the first embodiment, this air-conditioning servicing unit is connected with air-conditioner, it specifically comprises a stop valve 12, a check valve 11 and a throttling arrangement 13, wherein, this stop valve 12 is connected with the gas-liquid separator 40 in air-conditioner, this check valve 11 is connected between gas-liquid separator 40 and stop valve 12, and this check valve 11 is by the direction conducting of gas-liquid separator 40 to stop valve 12, and this throttling arrangement 13 is in parallel with check valve 11.Be in the low-pressure area of air-conditioner due to gas-liquid separator 40, so the dirt that the air-conditioner operation produces is deposited on almost in the middle of gas-liquid separator 40.
When needs carry out blowdown to air-conditioner, only need opening stop valve 12, by the inner pressure that exists of gas-liquid separator 40, the dirt in gas-liquid separator 40 just can be discharged via check valve 11 to stop valve 12 automatically, realize the blowdown of air-conditioner, reached the purpose of cleaning air-conditioner built-in system.In addition, when air-conditioner lacks refrigerant, can carry out by stop valve 12 notes that rush of refrigerant, for preventing the impact to gas-liquid separator 40, the refrigerant throttling arrangement 13 of flowing through, enter into gas-liquid separator 40 again after buffering, the refrigerant super-addition while realizing the air-conditioner operation.
Technical solutions of the utility model, by adopting check valve 11, stop valve 12 and throttling arrangement 13, can be cleared up the dirt of air-conditioner inside, avoid must the dismantle link of gas-liquid separator 40 of scrubbing, make the blowdown of air-conditioner simple.In addition, characteristic due to stop valve 12 self, can realize the filling of system refrigerant, and can be in the situation that air-conditioner is moving directly coolant injection in gas-liquid separator 40, the refrigerant that fills can not produce and impact gas-liquid separator 40 after throttling arrangement 13 bufferings.While also having avoided traditional approach to fill on the impact of air-conditioner return-air.
With reference to Fig. 2, Fig. 2 is the structural representation of the utility model air-conditioning servicing unit the second embodiment.
Based on above-mentioned the first embodiment, this air-conditioning servicing unit also comprises a magnetic valve 14, and this magnetic valve 14 is connected with check valve 11 and throttling arrangement 13, and with the port of export of the oil eliminator 30 of air-conditioner, is connected.When air-conditioner during at cold-starting, the hypotony of the low-pressure area (as gas-liquid separator 40) in air-conditioner, cause low-pressure area and higher-pressure region (as oil eliminator 30) to produce larger pressure reduction, and excessive pressure reduction can impel the compression ratio of the compressor 20 of air-conditioner to increase, the operating load of compressor 20 increases, and easily causes the damage of compressor 20.The magnetic valve 14 of setting up is when the air-conditioner cold-starting, can draw from oil eliminator 30 a small amount of refrigerant through magnetic valve 14 to gas-liquid separator 40, and the refrigerant in gas-liquid separator 40 is heated and disturbance, by controlling the opening time of magnetic valve 14, thereby reach the purpose that improves low-pressure area (gas-liquid separator 40) pressure, poor with the high-low pressure of balance air-conditioner built-in system.
Technical solutions of the utility model are by adopting magnetic valve 14 can make air-conditioner when cold-starting moves, on the one hand can heat air liquid/gas separator 40, liquid refrigerants is wherein evaporated as early as possible, improve the pressure of air-conditioner low-pressure area, while is also carried out disturbance to oil and the refrigerant of gas-liquid separator 40 inside, destroy the layering of oily in gas-liquid separator 40 and cold-producing medium, oil and refrigerant are better mixed, also be beneficial to the oil return of spill port on gas-liquid separator 40 mufflers, guarantee the recirculating oil quantity of compressor 20, also avoided the possibility of 20 times liquid of compressor simultaneously.In addition, when air-conditioner was out of service, opens solenoid valve 14, carried out balance to air-conditioner built-in system height pressure reduction, prevents from causing because pressure reduction is excessive damage to the part valve body, improves the stability of air-conditioner.
With reference to Fig. 3, Fig. 3 is the structural representation of the utility model air-conditioning servicing unit the 3rd embodiment.
Based on above-mentioned the second embodiment; this air-conditioning servicing unit also comprises an auxiliary throttling arrangement 15; should be connected between magnetic valve 14 and oil eliminator 30 by auxiliary throttling arrangement 15; after magnetic valve 14 is opened; refrigerant in oil eliminator 30 can be after the buffering of auxiliary throttling arrangement 15 in entering gas-liquid separator 40; avoid gas-liquid separator 40 to be subject to the impact of HTHP refrigerant, effectively protected gas-liquid separator 40.
With reference to Fig. 4, Fig. 4 is the structural representation of the utility model air-conditioning servicing unit the 4th embodiment.
Based on above-mentioned the first embodiment, this air-conditioning servicing unit also comprises an electric expansion valve 16, and this electric expansion valve 16 is connected with check valve 11 and throttling arrangement 13, and with the port of export of the oil eliminator 30 of air-conditioner, is connected.This electric expansion valve 16 both can play the effect of solenoid control pipeline opened/closed, can play again the throttling to refrigerant, the effect of buffering, made the parts of this air-conditioning servicing unit still less, and structure is simpler, and production cost is cheaper.
In above-mentioned all embodiment, because the proportion of dirt is heavier, easily in the bottom of gas-liquid separator 40 deposition, therefore this check valve 11 can be connected to the bottom of gas-liquid separator 40, so that better to the built-in system of air-conditioner, especially gas-liquid separator 40 carries out blowdown, makes the better effects if of blowdown.
The utility model further also proposes a kind of air-conditioning system, comprises air-conditioner outdoor unit and air-conditioning servicing unit, and this air-conditioner outdoor unit comprises the parts such as compressor 20, oil eliminator 30 and gas-liquid separator 40.The concrete structure of this air-conditioning servicing unit, with reference to above-mentioned all embodiment, does not repeat them here.Therefore adopted the technical scheme of above-mentioned all embodiment due to the air-conditioning servicing unit of this air-conditioning system, all these air-conditioning systems of beneficial effect that can bring of the air-conditioning servicing unit in above-mentioned all embodiment all have too, at this, also repeat no more.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
