【Description of the drawings】
Fig. 1 is the electric automobile air conditioner control logic circuit systematic schematic diagram of this utility model embodiment.
【Specific embodiment】
In order to solve above-mentioned technical problem, inventor considers to need to design second-order circuit.Firstorder circuit is aerator
Opening section circuit, opens aerator by air-conditioning control panel, and 12V controls power supply through blower switch to air-conditioning control panel
Interior heats switch and refrigeration switch, namely when aerator is not turned on, heats switch, refrigeration switch all non-communicated power supplies, open
Open aerator and can just open and heat or freeze, play a protective role.Second-order circuit is to heat partial circuit and refrigerating part circuit,
Heat in partial circuit and refrigerating part circuit and concatenate same normally closed relay, realize heating and making by the normally closed relay
Cold interlocking, when switch conduction is heated, heats partial circuit and forms closed-loop path, and air conditioning system starts to heat, while normally closed
Relay adhesive, refrigeration switch are disconnected with ground, and refrigerating part cannot work；When the switch conduction and heating of freezing is switched off,
Refrigerating part circuit is grounded to form closed-loop path via normally closed relay, and air conditioning system can start to freeze, as long as opening system
Behind hot part, refrigerating part cannot work, and play a protective role.Describe in detail by the following examples.
The electric automobile air conditioner control logic circuit system of the present embodiment, annexation are shown in Figure 1, including：Air-conditioning
Control panel 1, aerator 2, speed adjusting resistance 3, PTC catalysts 4, normally closed relay 5, electric fan 6, electric fan relay 7, temperature control
Switch 8, pressure switch 9, compressor 10, heat switch 11, blower switch 12, refrigeration switch 13 and ptc heater 14.
In specific work process, aerator 2 is opened by air-conditioning control panel 1 first, 12V controls power supply through aerator
The heating switch 11 and freezing in air-conditioning control panel 1 of switch 12 switchs 13.
When unlatching is heated, heat switch 11 and turn on, 12V controls power supply through heating switch 11 to PTC catalysts 4 so that
4 adhesive of PTC catalysts, ptc heater 14 work, and air conditioning system starts to heat；Simultaneously 12V controls power supply through heat switch 11 to
Normally closed relay 5,5 adhesive of normally closed relay, refrigeration switch 13 are disconnected with ground, even if now opening refrigeration, compressor control is believed
Number line switch 13 that cannot also pass through to freeze is grounded, it is impossible to work.
When open refrigeration when, refrigeration switch 13 turn on, compressor control signal line through pressure switch 9, temperature detect switch (TDS) 8,
After refrigeration switch 13, normally closed relay 5, ground connection is (it should be noted that pressure switch 9 is to lead with temperature detect switch (TDS) 8 under normal circumstances
Logical state), compressor 10 works, and air conditioning system starts to freeze.If now open heating, heat switch 11 and turn on, normally closed relay
5 adhesive of device, compressor control signal line are disconnected with ground, and air conditioning system stops refrigeration, starts to heat.
In addition, speed adjusting resistance 3 is serially connected with heat in partial circuit and refrigerating part circuit, for adjusting air-conditioner temperature.Electricity
Son fan relay 7 and electric fan 6 are serially connected with and heat in partial circuit and refrigerating part circuit, for importing into electric automobile
Hot and cold air.
To sum up, can be seen that by the above-mentioned course of work and principle Fig. 1, only when aerator is opened, heat the control with refrigeration
Power supply processed could be turned on；Regardless of whether having turned on refrigeration, as long as unlatching is heated, compressor ground signalling will disconnect so that
Refrigeration cannot work or quit work.Effectively avoid user open when aerator is forgotten out heat or freeze and while
Open the potential safety hazard for heating and being brought when freezing.
Here description of the present utility model and application are all simply illustrative and exemplary, are not intended to this practicality is new
