5 DEG C or more work, but are unable to satisfy vehicle heating demand.
Second is Gas-supplying enthalpy-increasing heat pump system, this scheme is by heating water in existing HVAC (heating and ventilation and air-conditioning)
Heater cores are changed to condenser, and when operation of heat pump, condenser heat dissipation, outdoor heat exchanger then absorbs heat, reaches heat outside vehicle
It is sent to interior purpose；Simultaneously in order to promote heat pump heating capacity and promote low-temperature working ability, heat pump operating mode uses 2
Grade throttling and gas-liquid separator and dedicated Gas-supplying enthalpy-increasing compressor, this system operating temperatures range can be promoted to >=-10 DEG C,
And heating capacity promotes about 10%, but components, using excessively, special-purpose member is at high price.
Summary of the invention
The first purpose of this invention is to provide a kind of heat pump system, solve conventional heat pump system heat pump performance it is low and at
This high problem.
Second object of the present invention is to provide a kind of air-conditioning, solves the problems, such as that traditional air conditioner is at high cost.
Third object of the present invention is to provide a kind of automobile, solves orthodox car air conditioning performance difference and at high cost asks
Topic.
The embodiment of the present invention is achieved in that
A kind of heat pump system, comprising:
Compressor, condenser, outdoor heat exchanger, gas-liquid separator, evaporator, the first electromagnet cut off valve, the second electromagnetism are cut
