Specific embodiment
Referring to Figure of description 1 to a kind of energy-saving low-temperature heat pump air conditioner control system for electric coach of the utility model make with
Under explain in detail.
A kind of energy-saving low-temperature heat pump air conditioner control system for electric coach of the utility model, structure include compressor 1, steam
Device 2, condenser 3 and main expansion valve 4 are sent out, passes through pipeline between the compressor 1, evaporator 2, main expansion valve 4 and condenser 3
Form a main circulation loop, be provided with economizer 5 between the evaporator 2 and main expansion valve 4, evaporator 2 and compressor 1 it
Between be provided with a tonifying Qi circuit, the tonifying Qi circuit includes tonifying Qi inlet pipe 61 and tonifying Qi outlet pipe 62, the tonifying Qi inlet pipe 61
Both ends be connected respectively with an import of evaporator 2 and economizer 5, the both ends of tonifying Qi outlet pipe 62 benefit with compressor 1 respectively
Port is connected with the one outlet of economizer 5, is provided with tonifying Qi solenoid valve 7 and economizer expansion valve on the tonifying Qi inlet pipe 61
8, exhaust gas temperature sensor 9, the benefit between economizer 5 and compressor 1 are provided on the pipeline between compressor 1 and evaporator 2
It is provided with pressure sensor 10 in gas outlet pipe 62, further includes the outdoor temperature sensor being arranged in outside compartment, the tonifying Qi electricity
Magnet valve 7 controls its switch, the economizer expansion valve 8 by outdoor temperature sensor or 9 value of feedback of exhaust gas temperature sensor
Its aperture is controlled by 10 value of feedback of pressure sensor.
The main expansion valve 4 is heating power expansion valve.
The compressor 1 uses permanent magnet synchronous motor.
When control system intelligent decision opens tonifying Qi.
When 1 excessive discharge temperature of compressor, tonifying Qi circuit overheat can be controlled by control 8 aperture of economizer expansion valve
Degree reduces delivery temperature.
Three-in-one integrated type power module drives 1 permanent magnet DC motor of compressor, energy-efficient.
Compressor 1 uses permanent magnet synchronous motor, and mutually more common threephase asynchronous machine is more efficient.
Control system uses CAN communication mode, major loop operation information, tonifying Qi circuit pressure, temperature, economizer expansion valve
8 apertures can show at panel in real time, facilitate monitoring and after-sales service.
Major loop realizes throttling using heating power expansion valve, stable, easily controllable；Tonifying Qi circuit using tonifying Qi solenoid valve 7 and
Economizer expansion valve 8 realizes the throttling under non-heating mode, and under dual guarantee refrigeration mode, refrigerant does not flow through tonifying Qi circuit
Compressor 1 is returned to, so that causing refrigeration effect decline and system unstable.
Under heating mode, the real-time detection tonifying Qi circuit degree of superheat, control economizer expansion valve 8 realizes the section in tonifying Qi circuit
Stream, control precision is more accurate, and sensitivity is higher, effectively controls 1 delivery temperature of compressor in optimum range, guarantees that low temperature is disliked
Under bad operating condition, system stable operation.
Tonifying Qi circuit is equipped with pressure sensor 10, real-time monitoring system pressure, by intelligent PID logic operation, from
It is dynamic to adjust 1 frequency of compressor and fan delivery, air-conditioning Energy Efficiency Ratio is promoted to greatest extent, is extended heating and defrosting interval, is shortened heating
Defrosting cycle effectively extends vehicle course continuation mileage.
When heating circulation, 9 real-time monitoring environment temperature of outdoor temperature sensor and exhaust gas temperature sensor, outdoor temperature is passed
Sensor set target temperature value near freezing point, i.e., when outdoor temperature freezing point around and above when, tonifying Qi solenoid valve 7 be in close
Closed state, tonifying Qi circuit and economizer 5 do not work, and air-conditioning system is only realized by main circulation loop and heated.When outdoor temperature passes
Sensor monitors temperature when below freezing, and it is poor to depend merely on main circulation loop heating effect at this time, and control tonifying Qi solenoid valve 7 is opened
It opens, some refrigerant enters economizer 5 via tonifying Qi solenoid valve 7 and economizer expansion valve 8, and refrigerant is from low-temp low-pressure liquid gas
Admixture becomes steam condition, is injected into compressor 1, injects more compressed gas for it, realizes enthalpy-increasing effect, heating effect
Fruit is promoted.
When exhaust gas temperature sensor 9 monitors excessive discharge temperature, control tonifying Qi solenoid valve 7 is opened, some refrigerant
Economizer 5 is entered via tonifying Qi solenoid valve 7 and economizer expansion valve 8, refrigerant becomes from low-temp low-pressure liquid gas admixture
Steam condition is injected into compressor 1, realizes enthalpy-increasing effect, and cool down to compressor 1, reduces delivery temperature, works as exhaust
Temperature drops to set temperature target value hereinafter, tonifying Qi solenoid valve 7 is closed.
