In the related technology, referring to Fig. 1, vehicle includes engine 100, engine cooling system 200 and refrigeration unit 300.
Wherein, engine cooling system 200 includes cooling pipe 210, pump 220, radiator 230 and liquid reserve tank 240, pump 220
Coolant liquid (such as water) is sucked in the cooling duct in engine 100, the coolant liquid after cooling engine 100 is dropped by radiator 230
Temperature simultaneously continues cycling through back pump 220, realizes recycling for coolant liquid.When coolant liquid deficiency in cooling pipe 210, pump 220
Coolant liquid can be obtained from liquid reserve tank 240.In general, the temperature into the coolant liquid of engine 100 is less than specific temperature threshold value (such as 80
℃).When engine cooling system 200 and 100 synchronization action of engine, i.e. engine 100 work, engine cooling system 200 is to engine 100
It is cooled down, prevents 100 temperature of engine excessively high.
Dependent refrigeration unit 300 on vehicle includes compressor 310, condenser module 320 (outer machine) and evaporator mould
Block 330 (interior machine) is connected between compressor 310, condenser module 320 and evaporator module 330 by pipeline (such as hose).This
The compressor 310 of embodiment is equipped with clutch, is connect by belt pulley or other power transmitting assemblies with engine 100, works as engine
When 100 operation, clutch is attracted, and engine 100 drives compressor 310 to rotate by belt pulley or other power transmitting assemblies.
Wherein, condenser module 320 includes condenser, and evaporator module 330 includes evaporator.When refrigeration unit is freezed,
The circulation loop of refrigerant are as follows: compressor 310- > condenser module 320- > evaporator module 330- > compressor 310.Modules
Between circulation loop formed by piping connection.Flow can be equipped on pipeline between condenser module and evaporator module to adjust
Device 340, the flow for flowing to the refrigerant of evaporator module for adjusting condenser module.Optionally, compressor 310 uses swash plate
Formula compressor, oscillating compressor or other kinds of compressor.
Summer high temperature (temperature > 43 DEG C) weather, in the environment, the condensation temperature of system is general for the exposure of condenser module 320
At 50 DEG C or more, casing 311 and excessive discharge temperature (delivery temperature > 120 DEG C, 311 temperature > 100 of casing of compressor 310
DEG C), 310 seal member of lubricating oil quality and compressor can be destroyed, so as to cause the damage of compressor 310.In addition, engine 100
Revolving speed is by being determined according to the driving of driver needs, so the revolving speed for passing to compressor 310 is uncontrollable.In high temperature
Under environment, if 310 revolving speed of compressor is excessively high, the casing 311 and delivery temperature of compressor 310 can be further improved.
For this, the relevant technologies cool down compressor 310 by 310 spray system of compressor, specifically, in compressor
Exhaust gas temperature sensor or switch are set on 310 exhaust pipes；Referring to fig. 2, between refrigerant system condenser outlet and air intake duct
It is arranged hydrojet branch (shown in Fig. 2), hydrojet branch road is equipped with the first solenoid valve 350 (normally closed).When exhaust gas temperature sensor or open
After pass detects that 310 delivery temperature of compressor is higher than a certain setting value, the first solenoid valve 350 is opened, a part of liquid refrigerants quilt
310 air intake duct of compressor and vaporization absorption heat are sucked, thus temperature of the cooling compressor 310 to safety.Hydrojet branch road is set
The coolant quantity for having spray hole to flow through when limiting hydrojet, plays the role of reducing pressure by regulating flow.In addition, the diameter of spray hole cannot be too
Greatly, usually < 1.0mm.However, hydrojet can reduce the cold medium flux in normal refrigerating circuit, coolant quantity is caused to decline 5~15%.
Moreover, hydrojet is limited the reduction of 310 delivery temperature of compressor by spray hole, under hot weather, if 100 revolving speed of engine
Very high, 310 delivery temperature of compressor still can be excessively high.
In addition, in the related technology, after 310 delivery temperature of compressor is more than safety value, compressor 310 can be forced to stop work
Make until delivery temperature is restored within safety value.However, force compressor 310 stop working meeting prevent refrigeration system from just
Often work, the low temperature food product or cargo that vehicle is transported cannot be stored well, and eventually going bad leads to customer claim.
And winter low temperature weather, after one night of vehicle parking, 310 temperature of compressor is lower, and refrigerant can potentially migrate into compressor
In 310, the cold start-up of compressor 310 easily causes liquid hammer and damages.Refrigeration unit 300 is generally defrosted and is made using hot-gas bypass mode
Heat, heating capacity depend on 310 temperature of compressor, and when microthermal climate heats, 310 temperature of compressor is low, and the heating capacity of unit is not high.
As shown in Fig. 2, hot gas defrosting/heating bypass is arranged between evaporator and compressor 310, set in hot gas defrosting/heating bypass
There is second solenoid valve 360 (normally closed).When exhaust gas temperature sensor or switch detect 310 delivery temperature of compressor lower than a certain pre-
If after value, second solenoid valve 360 is opened, and hot gas defrosting/heating bypass, condenser is in an off state, thus to compression
Machine 310 is heated.
In view of the foregoing drawbacks, the embodiment of the present invention on the compressor 310 that conventional vehicle-mounted engine 100 drives by increasing
Heat exchanger channels 1, and be connected with car engine cooling system 200, the temperature of compressor 310 can be effectively reduced under hot weather,
Prevent compressor 310 from overheating and damaging；When microthermal climate is cold-started, pre- thermocompressor 310 can be shifted to an earlier date, reduce liquid hammer risk.
