Major loop 18 also can be called as refrigerating circuit or direct expansion loop.Conventionally, the described component part of major loop 18 forms steam compression cycle and moves as steam compression cycle.Major loop 18 is filled with refrigerant medium, and it is operating as the working fluid for major loop 18.Major loop 18 is arranged in passenger carriage 12 without any part, and major loop 18 can separate from passenger carriage 12 completely by comprising the structure of fireproof bulkhead (not shown).Refrigerant medium can be for example (and without limitation): R32, R410A, R134a, R152a or other single halogenated hydrocarbons; Non-halogenated hydrocarbon, for example propane; Ammonia; Or carbon dioxide.
Working fluid for temperature booster loop 14 is first liquid medium, different from refrigerant.Similarly, chiller circuit 16 is filled with second liquid medium.First liquid medium and second liquid medium can be or can not be identical material, but both cooling system conditioner or heat-transfer fluid.First liquid medium and second liquid medium both flow in passenger carriage 12, and can therefore be subject to due to possible with passenger contact more restrictions.The example that is used for the cooling system conditioner of first liquid medium and second liquid medium can include but not limited to: the anti-freeze additive solution of the propylene glycol of water or water, Ethylene glycol or diethylene-glycol.
Major loop 18 comprises compressor 20, and it is pressurizes refrigerant, and makes refrigerant move through major loop 18.Compressor 20 can be by electric drive or Mechanical Driven.Compressor 20 becomes liquid by refrigerant from gas conventionally, and allows refrigerant move to liquid-cooled condenser 22.In liquid-cooled condenser 22, the first liquid medium in refrigerant and temperature booster loop 14 is in direct heat-exchange communication.
In the time of in liquid-cooled condenser 22, refrigerant forms from condensation of gas to liquid, thereby occur in thermal exchange in liquid-cooled condenser 22, is the working fluid from refrigerant to temperature booster loop 14, and this working fluid is liquid.Therefore, the thermal exchange in liquid-cooled condenser 22 occurs as from gas refrigerant to liquid, two phase refrigerant is to liquid and liquid refrigerant to liquid, wherein when refrigerant becomes liquid from gas, because latent heat discharges, a large amount of thermal exchanges occurs.
After flowing through liquid-cooled condenser 22, the flow of refrigerant in major loop 18 is to expansion valve 24, and described expansion valve is dropping equipment or gauging device.Many refrigerants or ownership cryogen are changed to two-phase state (liquids and gases the two) by expansion valve 24 and subsequently by liquid warming formula evaporator 26.
Expansion valve 24 can be temperature regulating valve door or het expansion valve, and is configured to keep constant evaporator superheat state when refrigerant enters liquid warming formula evaporator 26.There is not the electronics package relevant to conventional het expansion valve.Expansion valve 24 can for example leave the temperature of the refrigerant of liquid warming formula evaporator 26 by sensor or thermo detector (bulb) monitoring, and can improve heat exchange performance by allowing refrigerant additional or still less enter liquid warming formula evaporator 26.In liquid warming formula evaporator 26, refrigerant (no matter its phase how) with the second liquid medium of chiller circuit 16 in direct heat-exchange communication.
In normal operating period, major loop 18 have fixed flow directions (conter clockwise normally, as shown in Figure 1).Therefore, refrigerant flows through liquid-cooled condenser 22 from compressor 20, subsequently by expansion valve 24, and subsequently by liquid warming formula evaporator 26, and get back to compressor 20.Should note during parking or start-up course, or under extreme case, it is possible that some refrigerants flow in opposite direction.
Temperature booster loop 14 has and the passenger carriage 12 temperature booster core 30 of thermal communication optionally.The first pump 32 allows first liquid medium motion by temperature booster loop 14.The first pump 32 and other pumps as herein described can have fixing or variable discharge capacity and can be driven by being connected to another turning unit or dedicated motor (not shown).

Therefore, when using bypass path 336, some or all of first liquid media move between temperature booster core 330 and liquid-cooled condenser 322, and not by low-temperature radiator 334.When in air cold and temperature booster loop 314, expectation is heated around, bypass path 336 allows temperature booster loops 314 to keep heats, and does not discharge heat.And then when air ratio first liquid medium is warmmer around, bypass path 336 allows temperature booster loop 314 to avoid collecting extra heat.
The chiller circuit 316 of atmosphere control system 310 is filled with second liquid medium, and comprises cooling vessel core 340, its optionally with passenger carriage 312 and chiller circuit 316 thermal communications.The second pump 342 allows second liquid medium motion by chiller circuit 316.
Liquid warming formula evaporator 326 heat connect chiller circuit 316 and major loop 318.Therefore, at least one in major loop 318 and first liquid medium (by liquid-cooled condenser 322) and second liquid medium (by liquid warming formula evaporator 326) be in direct heat-exchange communication, and first liquid medium and second liquid medium are at the liquid form always of operating period normally.
Chiller circuit 316 also comprises auxiliary thermal source 348.Auxiliary thermal source 348 can be such as but not limited to: electric resistance heater, from water or the exhaust heat circulation heat exchanger of explosive motor.Other structures of atmosphere control system 310 can be included in the auxiliary heater in temperature booster loop 314.
In atmosphere control system 310, both are optionally communicated with temperature booster core 330 and cooling vessel core 340 with public air stream 350.Therefore, the cooling and dehumidifying of device core 340 that can be cooled of public air stream 350, and subsequently by temperature booster core 330 heating, thereby passenger carriage 312 is heated and dehumidifies.
Detailed description in accompanying drawing and demonstration are to support of the present invention and description, and scope of the present invention only limits by claim.Although carried out detailed description to carrying out better model of the present invention, it is routine that those skilled in the art can learn that being used in the scope of appended claim implemented many replacement design and implementations of the present invention.
