Heat suitablely.Used heat from internal combustion engine is sent to heater core by such as cooling agent based on ethylene glycol etc heat transfer liquids
Portion, herein the heat energy from heat transfer liquids be transferred to be flow to by heater cores the surrounding air in compartment.With bigger efficiency
The appearance of internal combustion engine, the especially hybrid vehicle with smaller internal combustion engine and electric vehicle, it is the passenger in compartment that can be used for
The heat energy for providing comfortableness can be inadequate.
In order to provide additional heat to the compartment of the vehicle with smaller internal combustion engine, it is known that in heat pump mode operating air conditioner system
System.Typical air conditioning system for motor vehicle includes evaporator in HVAC module and positioned at being externally exposed surrounding air
Condenser in anterior cabin.Compressor makes two phase refrigerant cycle through evaporator, and the refrigerant is come from by absorption herein
The heat in compartment and be expanded into low-pressure steam refrigerant.After low-pressure steam is compressed by the compressor into HCS, vapor phase
Refrigerant is transferred to condenser, and highly pressurised liquid refrigeration is condensed into this HCS is by rejecting heat to environment substantially
Agent.Liquid phase refrigerant is back to evaporator by expansion gear, the expansion gear make high pressure liquid refrigerant change into liquid and
The low pressure mixture of vaporous refrigerant is with persistent loop.By in heat pump mode operating air conditioning system, cold-producing medium stream countercurrently,
In the situation, condenser is absorbed from the heat in ambient air outside by evaporated liquid refrigerant, and evaporator passes through
Condense vaporous refrigerant and discharge to compartment heat.Low-pressure side when being used for air conditioning mode due to air-conditioning system can become
High-pressure side when being for heat pump mode, thus in heat pump mode one of operating air conditioning system have the disadvantage because needs must not

Outward, it is necessary to be strengthened to evaporator to bear high-pressure refrigerant, and install additional together with additional associated pipe
Expansion gear and receiving device.In heat pump mode another known disadvantage of operating air conditioning system be under colder weather, by
Drop to less than 32 °F in the surface temperature of condenser so that any moisture being condensate on condenser surface can freeze, thus
The efficiency of system can be reduced and condenser can be even damaged.
Known electric heater is used for the compartment offer additional heat for using air-conditioning system as the vehicle of heat pump.Most cold
Under cold weather, it is known that operating air conditioning system is invalid in heat pump mode；Accordingly, it would be desirable to additional electric heater.However,
For mixing and electric vehicle, electric heater represents can increase current draw, and this can significantly reduce driven by power
Scope.
In sum, it is necessary to a kind of compartment to motor vehicles provides the heating system of additional heat, the heating system without
The refrigerant circulation of air-conditioning system need to be made to reverse or negatively affect driven by power scope.
