Abstract
The utility model relates to an automotive air conditioner, in particular to a high-pressure ejection oil return automotive air conditioner, which comprises an ejector, a compressor, a solenoid valve, a first oil collection pocket, a condenser, a second oil collection pocket, an evaporator and an expansion valve. The air conditioner is characterized in that: the compressor is sequentially in closed loop connection with the condenser, the expansion valve and the evaporator; the first oil collection pocket is arranged at the bottommost point of the evaporator; and the second oil collection pocket is arranged at the bottommost point of the condenser. The air conditioner has the advantages that: lubricating oil returns back to the compressor under the high pressure of the condenser, so that the oil starvation of the compressor is prevented; and the air conditioner is easy to control, mount and produce, and is reliable in running.
Description
Technical field
The utility model relates to air conditioning for automobiles, especially a kind of high pressure injection oil return air conditioning for automobiles.
Background technology
In the automotive air-conditioning system running, condenser, evaporimeter and conveying pipe of refrigerant road all 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, adopts a kind of high pressure injection oil return air conditioning for automobiles, when lubricant level is too high in detecting the oil-collecting bag lubricating oil is drained into compressor crankcase, and easy operating is installed simply.
For realizing above-mentioned purpose; The technical scheme of the utility model is to adopt a kind of high pressure injection oil return air conditioning for automobiles; Comprise injector, compressor, magnetic valve, the first oil-collecting bag, condenser, the second oil-collecting bag, evaporimeter, expansion valve; Described compressor is connected with condenser, expansion valve, evaporimeter closed loop successively, and the described first oil-collecting bag is installed in the evaporimeter lowermost, and the described second oil-collecting bag is installed in the condenser lowermost.
The described second oil-collecting bag is connected in the crankcase of compressor after pipeline connects magnetic valve and injector successively.
Described second oil-collecting is assured in the diversion chamber that is connected to injector.
The basic principle of the utility model: after using the utility model, the lubricating oil that flows to the oil-collecting bag is too much, and magnetic valve is opened, and lubricating oil is drained into compressor crankcase, and lubricate compressors prevents that effectively compressor lacks lubricating oil, causes fault.
The beneficial effect of the utility model is:
(1) utilizes the high pressure of condenser that lubricating oil is taken back 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, injector 2, compressor 3, magnetic valve 4, the first oil-collecting bag 5, condenser 6, the second oil-collecting bag 7, evaporimeter 8, expansion 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 high pressure injection oil return air conditioning for automobiles; Comprise injector 1, compressor 2, magnetic valve 3, the first oil-collecting bag 4, condenser 5, the second oil-collecting bag 6, evaporimeter 7, expansion valve 8; Described compressor 2 is connected with condenser 5, expansion valve 8, evaporimeter 7 closed loop successively, and the described first oil-collecting bag 4 is installed in evaporimeter 7 lowermost, and the described second oil-collecting bag 6 is installed in condenser 5 lowermost.
The described second oil-collecting bag 6 is connected in the crankcase of compressor 2 after pipeline connects magnetic valve 3 and injector 1 successively.
The described second oil-collecting bag, 6 pipelines are connected in the diversion chamber of injector 1.
The course of work of the utility model is:
In the refrigeration system of air conditioning for automobiles air-conditioning, compressor 2 is connected with condenser 5, expansion valve 8, evaporimeter 7 closed loop successively, behind use the utility model; When the air conditioning for automobiles air-conditioning system is worked; Lubricating oil is compressed machine 2 and discharges, and through condenser 5 and evaporimeter 7, this moment, lubricating oil accumulated in the first oil-collecting bag 4 and the second oil-collecting bag 6; Automobile air conditioner compressor runs to the lubricating oil of oil-collecting bag 8 when too much continuously; Open magnetic valve 3, lubricating oil is ejected into the crankcase of compressor 2 from the second oil-collecting bag 6 from injector 1, this moment, the first oil-collecting bag, 4 lubricating oil were under the diversion chamber low-pressure suction of injector 1; With the crankcase that sprays to compressor 2 that has that is sprayed, lubricate compressors 2.
The advantage of present embodiment is, utilizes the high pressure of condenser 5 that lubricating oil is taken back compressor 2, prevents compressor 2 oil starvations and damages, and control is simple, and is reliable, installs simply, is easy to production operation.
