Abstract
The utility model discloses an automobile air conditioning system. The on-off state of a control loop of a compressor and the on-off state of a control loop of a condenser fan are controlled through a high and low pressure switch and a normally open contact of a temperature relay, and a working loop of the compressor and a working loop of the condenser fan share one fuse. According to the automobile air conditioning system, the working loop of the compressor and the working loop of the condenser fan share the fuse, accordingly, after the fuse is ablated by the condenser fan, the compressor also stops working, and the condition that after the fuse on the working loop of the condenser fan is ablated, a clutch of the compressor is ablated due to the fact that the high and low pressure switch loses efficacy is effectively avoided.
Description
Technical field
The utility model relates to a kind of automotive air-conditioning system, relates in particular to compressor and the work loop of condenser and the design of control loop to automotive air-conditioning system.
Background technology
Air-conditioning system in automotive electrical system is trouble point occurred frequently, and in air-conditioning system, the damage of each parts all may cause whole-vehicle air-conditioner system to break down, and especially in hot summer, it is even more important that the reliability of air-conditioning system just seems.In order to guarantee the Proper Match of air-conditioning system electric loop wire and insurance, in air-conditioning system, the work loop of compressor and condenser fan adopts independently insurance design conventionally, as shown in Figure 1, on the work loop of compressor P, fuse F1 is set, on the work loop of condenser fan M2, fuse F2 is set, for the air-conditioner control system shown in Fig. 1, the work loop of compressor P and the work loop of condenser fan M2 are separate under normal conditions, in the time that condenser fan M2 does not work, compressor P can normally work, only have in the time that air-conditioning system hypertonia causes the high-low pressure switch P K disconnection on air-conditioning duct, compressor P and condenser fan M2 all cannot work.For this kind of air-conditioner control system, in the time that it occurs extremely causing fuse F2 ablation, compressor works long hours and can make system pressure too high, in this kind of situation, the work loop of compressor P can not be cut off if high-low pressure switch P K breaks down, compressor clutch ablation will be caused so.As can be seen here, there is following defect in existing automotive air-conditioning system: independently insurance design occurs when abnormal, may causing compressor clutch ablation at air-conditioner control system; The synchronous working design of compressor and condenser fan can cause air-conditioner control system in the time of work subtransient, affects the normal use of other system because working pulse electric current is excessive.
Utility model content
The above defect that the utility model exists in order to solve existing automotive air-conditioning system, at least provide a kind of fuse on the work loop of condenser fan to burn after also out-of-work automotive air-conditioning system simultaneously of compressor.
To achieve these goals, the technical solution adopted in the utility model is: a kind of automotive air-conditioning system, by the control loop of normally opened contact control compressor of high-low pressure switch and temperature relay and the on off operating mode of the control loop of condenser fan, the work loop of described compressor and the work loop of described condenser fan share fuse.
Preferably, the normally opened contact of described high-low pressure switch and described temperature relay is electrically connected in the control loop of described compressor, and the normally opened contact of compressor start relay is electrically connected in the control loop of condenser fan.
Preferably, the work loop of described compressor comprises normally opened contact and the described compressor of the described fuse being electrically connected between normal electric terminal and ground terminal, described compressor start relay; The work loop of described condenser fan comprises the described fuse being electrically connected between described normal electric terminal and described ground terminal, normally opened contact and the condenser fan of condenser starting relay.
Preferably, the control loop of described condenser fan comprises the normally opened contact of the described fuse being electrically connected between described normal electric terminal and ground terminal, described compressor start relay and the coil of described condenser starting relay.
The beneficial effects of the utility model are: the work loop of the compressor of automotive air-conditioning system of the present utility model and the work loop of condenser fan share fuse, therefore, at condenser fan by after fuse ablation, compressor also will quit work, effectively avoid after the fuse ablation on the work loop of condenser fan, occur because high-low pressure switch failure causes the situation of compressor clutch ablation; In addition, by the normally opened contact of compressor start relay being electrically connected in the control loop of condenser fan, make condenser fan be controlled by compressor start relay, compressor and condenser fan start timesharing like this, working pulse electric current can effectively reduce automotive air-conditioning system startup time, avoids affecting other system work.

The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Be exemplary below by the embodiment being described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
As shown in Figure 2, automotive air-conditioning system of the present utility model is the same with existing automotive air-conditioning system, still from high-low pressure switch P K and temperature relay X2(according to Fig. 1 and 2, temperature relay X2 is controlled by the state of temperature controller T) the control loop of normally opened contact control compressor P and the on off operating mode of the control loop of condenser fan M2, different is, the work loop of compressor P and the work loop of condenser fan M2 share fuse F4, at this, what it should be apparent to those skilled in the art that is, the control loop of compressor P is the loop at the coil place of compressor start relay X4, the control loop of condenser fan M2 is the loop at the coil place of condenser starting relay X3, the work loop of compressor P is the normally opened contact of compressor start relay X4 and the loop at compressor P place, the work loop of condenser fan M2 is the normally opened contact of condenser starting relay X3 and the loop at condenser fan M2 place.
For compressor P and condenser fan M2 can be started in timesharing, as shown in dotted line frame part in Fig. 2, the normally opened contact of high-low pressure switch P K and temperature relay X3 can be electrically connected in the control loop of compressor P, and the normally opened contact of compressor start relay X4 is electrically connected in the control loop of condenser fan M2, like this, coil at compressor start relay X4 obtains electric, make after the normally opened contact closure (now compressor P starts) of compressor start relay X4, the coil of condenser starting relay X3 just electric, condenser fan M2 just starts to start.For this enforcement structure, high-low pressure switch P K and temperature relay X3 control the on off operating mode of the control loop of condenser fan indirectly by compressor start relay X4.
