Abstract
The utility model relates to an air conditioner, in particular to an automobile air-conditioner. The automobile air-conditioner comprises a check valve, a capillary tube, a compressor, a first electromagnetic valve, an oil gathering bag, an evaporator, a condenser, an expansion valve, a second electromagnetic valve and a third electromagnetic valve, wherein the compressor is sequentially in closed-loop connection with the condenser, the third electromagnetic valve, the expansion valve, the evaporator and the first electromagnetic valve, an exhaust pipe of the compressor after passing through the second electromagnetic valve is connected with a liquid inlet of the evaporator by a pipe, and the oil gathering bag after sequentially passing through the capillary tube and the check valve is connected with a crankcase of the compressor by a pipe. In the utility model, a lubricant is exhausted back to the compressor through exhausting by using the compressor, therefore, the automobile air-conditioner disclosed by the utility model has the advantages of being simple to control, reliable in running, simple in installation, easy in producing operation, and capable of preventing the compressor from oil starvation.
Description
Technical field
The utility model relates to air-conditioning, especially a kind of air conditioning for automobiles.
Background technology
In the present air conditioning for automobiles running, evaporimeter can store the lubricating oil of a part of compressor.Automobile refrigerating air-conditioning system for no oil separating device; It is very few after the lubricating oil of discharging from compressor with higher pressure refrigerant gas is through a kind of refrigeration cycle, to get back to the inner oil mass of compressor; When being not enough to satisfy the lubricating requirement of compressor, petrol starvation can take place in compressor, causes lubricated insufficient; The lighter causes compressor operating operation troubles to occur, wear and tear parts and damage compressor of weight person.Existing automobile refrigerating air-conditioning system is utilized the mutual dissolution characteristics of cold-producing medium and lubricating oil; Compressor is also inhaled the crankcase of getting back to compressor with the lubricating oil that has in air-breathing simultaneously when sucking cold-producing medium; Because lubricating oil uses dissolving cold-producing medium ability to descend for a long time in the automobile refrigerating air-conditioning system, and the cold-producing medium that uses of air conditioning for automobiles is impure etc., and reason will cause effectively oil return.Therefore, be necessary to take measures to improve the oil return efficient of automobile refrigerating air-conditioning system.
Summary of the invention
The purpose of the utility model is to overcome defective of the prior art, invents a kind of air conditioning for automobiles, moved a period of time after, automatically lubricating oil is drained into compressor crankcase, install simple, easy operating.
For realizing above-mentioned purpose; The technical scheme of the utility model is to adopt a kind of air conditioning for automobiles; Comprise check valve, capillary, compressor, first magnetic valve, oil-collecting bag, evaporimeter, condenser, expansion valve, second magnetic valve, the 3rd magnetic valve; Described compressor is connected with condenser, the 3rd magnetic valve, expansion valve, evaporimeter, first magnetic valve closed loop successively, and described compressor exhaust pipe is connected with the evaporimeter inlet through second magnetic valve through pipeline.
Described oil-collecting bag is installed in the evaporimeter lowermost, and described oil-collecting bag is connected with the crankcase of compressor through capillary, check valve through pipeline successively.
The basic principle of the utility model: after using the utility model; Too much when the lubricating oil that flows to the oil-collecting bag, open second magnetic valve, close first magnetic valve and the 3rd magnetic valve; Compressor air-discharging with grease pump to compressor crankcase; Lubricate compressors prevents that effectively compressor lacks lubricating oil, causes fault.
The beneficial effect of the utility model is:
(1) with compressor air-discharging lubricating oil is flow back to compressor, prevent the compressor oil starvation.
(2) control is simple, reliable.
(3) install simply, be easy to production operation.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Among the figure: 1, check valve 2, capillary 3, compressor 4, first magnetic valve 5, oil-collecting bag 6, evaporimeter 7, condenser 8, expansion valve 9, second magnetic valve 10, the 3rd magnetic valve.
The specific embodiment
In conjunction with Fig. 1 the utility model specific embodiment is further described:
The technical scheme that provides according to the utility model; A kind of air conditioning for automobiles; Comprise check valve 1, capillary 2, compressor 3, first magnetic valve 4, oil-collecting bag 5, evaporimeter 6, condenser 7, expansion valve 8, second magnetic valve 9, the 3rd magnetic valve 10; Described compressor 3 and condenser 7, the 3rd magnetic valve 10, expansion valve 8, evaporimeter 6, first magnetic valve 4 closed loop successively are connected, and described compressor 3 blast pipes are connected with evaporimeter 6 inlets through second magnetic valve 9 through pipeline.
Described oil-collecting bag 5 is installed in evaporimeter 6 lowermost, and described oil-collecting bag 5 is connected with the crankcase of compressor 3 through capillary 2, check valve 1 through pipeline successively.
The course of work of the utility model is:
In the refrigeration system of air conditioning for automobiles air-conditioning, behind use the utility model, when the air conditioning for automobiles air-conditioning system is worked; Lubricating oil is compressed machine 3 and discharges, and flows to evaporimeter 6 through condenser and expansion valve, and temperature is low in the evaporimeter 6; The viscosity of lubricating oil increases, and is difficult for by the gaseous refrigerant dissolving and takes back compressor 3, and this moment, a large amount of lubricating oil accumulated in the oil-collecting bag 5; Work as accumulated running time, arrive the lubricating oil flow to oil-collecting bag 5 when too much, open second magnetic valve 9; Close first magnetic valve 4 and the 3rd magnetic valve 10, compressor 3 exhausts drain into compressor 3 crankcases, lubricate compressors 3 with lubricating oil.
The advantage of present embodiment is, with compressor 3 exhausts lubricating oil flow back to compressor 3, prevents compressor 3 oil starvations and damages, and control is simple, and is reliable, installs simply, is easy to production operation.
Claims (2)
1. air conditioning for automobiles; Comprise check valve, capillary, compressor, first magnetic valve, oil-collecting bag, evaporimeter, condenser, expansion valve, second magnetic valve, the 3rd magnetic valve; It is characterized in that: described compressor is connected with condenser, the 3rd magnetic valve, expansion valve, evaporimeter, first magnetic valve closed loop successively, and described compressor exhaust pipe is connected with the evaporimeter inlet through second magnetic valve through pipeline.
