Abstract
The utility model relates to an automobile air conditioner with a cold storage device, which is formed by orderly connecting a refrigerating compressor, a stored liquid drier, a condenser, an expansion valve and an evaporator by a refrigerant pipeline. The vicinity of an air outlet of the evaporator is provided with a refrigerant shunting branch, an outlet of the condenser is connected with a pipeline at one end of a shunting branch of which the other end passes through the cold storage device composed of an electromagnetic switch, a cold storage and expansion valve, a cold-storage evaporator and cold-storage working media to be connected with an inlet pipeline of the refrigerating compressor. Air streams in an air supply system orderly flow through the evaporator and the cold storage device, and then arrive at an outlet of the air supply system. The utility model has the characteristics that comfort temperature of the air outlet can be assured by an air conditioning system, and great temperature fluctuation of wind outlet is improved.
Description
Affiliated technical field
The utility model relates to a kind of air conditioner for motor vehicle, especially can improve the automotive air-conditioning system of leaving air temp traveling comfort.
Background technology
At present, for most of cars, lilliput car and construction machinery and equipment, the power of needed power of air-conditioning and driving automobile is all from same driving engine.All there is a common characteristic in this system: because vehicle behavior changes frequently, refrigerant flow alters a great deal.As the scroll compressor refrigeration system TR-60 of three electric companies, refrigerating capacity is when rotating speed 1120rpm: 5400KJ/h; Refrigerating capacity is when rotating speed 3500rpm: 10500KJ/h; When idling, refrigerating capacity is lower.Because the refrigerating capacity instability of refrigeration system, cause the air conditioner system air blast system to go out wind-warm syndrome also unstable, sometimes hot and sometimes cold, it is not very comfortable giving people's sensation.
Summary of the invention
In order to overcome existing air conditioning for automobiles leaving air temp less stable, to understand the deficiency that changes with the speed of a motor vehicle, the utility model provides a kind of automotive air-conditioning system with cold-storage device, this system can improve the deficiency of original system easily, improves the big characteristics of leaving air temp fluctuation effectively.
The technical scheme that its technical matters that solves the utility model adopts is: in automotive air-conditioning system, refrigerating compressor, liquid storage dryer, condenser, expansion valve, evaporator connect with refrigerant tubing successively, one refrigerant diverter branch is set, make condensator outlet and diverter branch one an end plumbing connection, the diverter branch other end is connected with a refrigerating compressor inlet duct after by a cold-storage device of being made up of electromagnetic switch, cold-storage expansion valve, cold-storage evaporator, agent for storage of coldness.When at high-speed running automobile, refrigerating capacity is far longer than actual needs, causes the air-conditioning wind pushing temperature on the low side, at this moment can pass through control system, opens electromagnetic switch, makes cold-storage device devote oneself to work, a part of refrigerating capacity is stored in the cold-storage device.Because cold-storage device has been shunted part of refrigerant, the refrigerant flow in the evaporator descends, and the air-conditioning wind pushing temperature will be brought up to a comfort temperature.When during the automobile low-speed running, because refrigerating capacity descends, wind pushing temperature is higher, at this moment closes electromagnetic valve by control setup, makes cold-storage device stop to fill cold.Simultaneously, make air by evaporator, again the cold of cold-storage device is discharged, make that the air-conditioning wind pushing temperature remains in the comfort standard in the automobile again by the air by-pass passage of cold-storage device.
The beneficial effects of the utility model are, can automobile in the air-conditioning wind pushing temperature remain in the comfort standard, simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a refrigeration system schematic diagram of the present utility model.
Fig. 2 is the sectional structural map of cold-storage device.
1. refrigerating compressors among the figure, 2. liquid storage dryer, 3. condenser, 4. expansion valve, 5. evaporator, 6. electromagnetic switch, 7. cold-storage expansion valve, 8. cold-storage evaporator, 9. cold-storage working substance, 10. cold-storage device, air by-pass passage in 11. cold-storage devices.
The specific embodiment
In Fig. 1, refrigerating compressor (1), liquid storage dryer (2), condenser (3), expansion valve (4), evaporator (5) connect with refrigerant tubing successively, one refrigerant diverter branch is set near evaporator (5), make condenser (3) outlet and diverter branch one end plumbing connection, the diverter branch other end is by cold-storage device (a 10) back and (1) refrigerant inlet plumbing connection of refrigerating compressor of being made up of electromagnetic switch (6), cold-storage expansion valve (7), cold-storage evaporator (8), cold-storage working substance (9).Comfortable for guaranteeing temperature out, the air-flow in the supply air system flows through evaporator, cold-storage device successively, arrives the supply air system outlet then.
Claims (2)
1. air conditioning for automobiles with cold-storage device, refrigerating compressor, liquid storage dryer, condenser, expansion valve, evaporator are linked in sequence with refrigerant tubing successively, it is characterized in that: condensator outlet and refrigerant diverter branch one an end plumbing connection, the diverter branch other end is connected with a refrigerating compressor inlet duct by behind the cold-storage device.
2. the air conditioning for automobiles of band cold-storage device according to claim 1, it is characterized in that: cold-storage device is to be linked in sequence with refrigerant tubing successively by electromagnetic switch, cold-storage expansion valve, cold-storage evaporator, sealing cold-storage working substance between shell and the cold-storage evaporator, in air by-pass passage is arranged.
