- the refrigerant bypass 33 would be conducted downstream of the second evaporator 19 and upstream of the suction throttle 15 to the refrigerant guide 20.
- the refrigerant bypass 33 is guided behind the suction throttle 35 to the refrigerant guide 20.
- the additional operation of the second evaporator 19 is present angest- REBT particular for the case that the coolant temperature is more than 40 0 C. up to 55 ° C.
- the suction pressure levels of the first evaporator 29 and the second evaporator 19 are designed differently by the suction throttle 35 according to the concept of the invention in the second variant.
- the suction throttle 35 is integrated into the manifold of the second evaporator 19, refrigerant downstream in the refrigerant guide 20.
- An expansion element 22 '- in the present example, in the form of a thermal expansion valve - controls the overheating of the suction throttle 35.
- a standard TXV thermo Expansion valve
- the refrigerant side pressure drop in the second evaporator 19 is not very critical in this case because it can be offset against the Saugdrosseldruckabfall.
- the suction throttle 35 may also be designed as an electrically actuated expansion valve or timing valve. As a result, the suction throttle 35 can be combined with the shut-off valve 28 '. The latter leads to the saving of an additional valve.
- Fig. 8 shows in views (A) and (B) two possible modifications for arranging a condenser 23 and coolant radiator 13 relative to each other, which are suitable for both variants of the invention.
- the coolant circuit is advantageously realized as a low-temperature circuit.
- the heat exchanger 11 is advantageously realized as an indirect intercooler.
- the coolant radiator 13 is advantageously realized in the form of a low-temperature radiator.
- View (A) of FIG. 8 shows the arrangement of the coolant cooler 13 and the condenser 23 as shown in FIGS. 1 to 7 described so far.
- a coolant-side switching valve 17 has proven to be advantageous in the manner described above for actuating the coolant-side bypass 10 ', so as to bypass the second evaporator 19 and thus to regulate indirectly.
- a switching valve 28 or shut-off valve 29 ' has proven to be particularly advantageous for switching off the second evaporator 19 in the form of the CAS evaporator. This causes a reduction of the coolant-side pressure drop and thereby a lower power consumption of the coolant pump 15, which ultimately leads to fuel savings.
- the second evaporator in the form of the CAS evaporator can also be replaced by a comparatively small refrigerant-side mass flow - e.g.
- the first variant the invention of the second evaporator designed as a CAS evaporator can also be arranged in series in front of the first evaporator designed as a HVAC evaporator.
- an arrangement of two shut-off valves for actuating the bypass sections 30 may be provided in each case instead of the three-way valves 24, 28.
- an expansion element in the form of a TXV or EXV can optionally be arranged at the location of the expansion elements 26, 26 ', 22, 22'.
- FIG. 9 A method for cooling an essentially gaseous charging fluid provided for charging an internal combustion engine with a previously described circuit 100, 200 for charging an internal combustion engine is shown in FIG. 9 as a logic flow diagram in a particularly preferred embodiment and in FIG. 10 with associated temperature profiles for a coolant temperature T on the one hand or an operating state V1 for a first evaporator 29 - which symbolizes the activity of the evaporator 29 in the form of the HVAC evaporator for cooling an ambient air or cabin air (eg in recirculation mode) - and an operating state V2 - which the activity of a second evaporator 19 symbolizes a refrigerant for cooling the refrigerant in the form of the CAS evaporator.
- the refrigerant bypass 33 for the second evaporator 19 is actuated in a first operating state B1 characterized by a coolant temperature lying below a limit temperature.
- the limit temperature is present in a range of 40 ° C to 50 ° C.
- the second evaporator 19 is inactive in this first operating state B1.
- the corresponding areas are indicated in FIG. 10 by B1.
- the coolant temperature is preferably below the limit temperature of, for example, 40 ° to 55 ° C.
- the CAS evaporator is not switched as a coupling element between the low-temperature cooling circuit and the refrigerant circuit or completely bypassed by the present refrigerant side bypass 33, actuated by the three-way valve 28.
- a coolant-side bypass can be provided to the additional cooling effect of the second evaporator 19 is not required.
- the CAS evaporator is preferably bypassed on the refrigerant side by means of the bypass 33 and a corresponding position of the three-way valve 28.
- the CAS evaporator as the second evaporator 19 can advantageously be kept at a comparatively low temperature level - similar to the temperature level of the HVAC evaporator as the first evaporator 29.
- the low temperature level can continue be favored. For example, this can be achieved by targeted opening - in the form of a low-frequency clocking - the shut-off valve on the CAS evaporator as the second evaporator 19.
- Another possibility is to obtain a very low refrigerant mass flow over a defined geometry in the expansion element 22 as a leak.
- the second evaporator 19 is as CAS evaporator in case of need, ie when additional charge air cooling power is required, at a relatively low temperature level.
- a low temperature level has a certain buffering effect when the second evaporator 19 is switched on, or allows a rapid cooling of the charge air - this before the coolant circuit with a coupled CAS evaporator would normally be started and would be in stationary operation.
- this measure has the advantage that the power consumption of a coolant pump 15, be it an electric or conventional coolant pump, is reduced due to the elimination of the coolant-side pressure drop of the CAS evaporator. As a result, fuel consumption is thus reduced.
- a second operating state B2 characterized by a coolant temperature lying above a limit temperature
- two operating substates B21 and B22 for cooling the charging fluid or, more specifically, for operating the first evaporator 29 and the second evaporator 19 are possible.
- a first operating substate B21 neither the refrigerant bypass 33 for the second evaporator 19 nor the refrigerant bypass 31 for the first evaporator 29 is actuated.
- the second variant of the invention opens - as already explained above - the shut-off valve 28 'of the second evaporator 29.
- both evaporators 29, 19 are active.
- This operating sub-state is suitable for the case that a power requirement of the first and second evaporators 29, 19 is below a power limit of the coolant guide 10.
- the first evaporator in the form of the HVAC evaporator remains switched on when the power at the CAS evaporator and the power of the HVAC evaporator does not exceed the total capacity of the refrigeration circuit.
- the air inlet temperature and the air quantity can be used for the respective output of the evaporators 19, 29. This is known for example by an engine control unit and / or a climate control device.
- the power control of the HVAC evaporator via an EXV or TXV as explained above and / or by measuring the pressure and temperature of the refrigerant after the CAS evaporator.
- EXV electric expansion device 26
- the decreased power on the HVAC evaporator can be varied according to the specification.
- the performance of the CAS evaporator can be regulated only comparatively poorly directly, but rather advantageously takes place indirectly through the HVAC evaporator.
- the power dissipated is set by the setting, overheating depending on the suction pressure.
- the setting is prioritized on the HVAC evaporator so that the power left over from the HVAC evaporator - that is, the rest of unevaporated refrigerant - is available to the CAS evaporator.
- the refrigerant-side performance of the CAS evaporator can be adjusted in parallel by the coolant-side changeover valve in the form of the three-way valve - also referred to as three / two-way valve - by clocking the valve 28 and 24 a certaindemit- telmassenstrom and thus a certain power decrease the coolant takes place.
- a power demand of the first and second evaporators is above a power limit of the refrigerant guide and the refrigerant bypass 33 for the second evaporator 19, and the refrigerant bypass 31 for the first evaporator 29 is operated mutually.
- this operation substate B22 corresponds to the case where the coolant temperature is more than 40 0 C to 55 ° C and the power demand is too high.
- the CAS evaporator as Koppelglied between the low-temperature cooling circuit and the refrigerant circuit is indeed switched to additional cooling of the coolant, but there is an alternate operation of both evaporators 19, 29 due to the high power requirement of the CAS evaporator to the coolant and / or refrigerant circuit.
- the evaporators 19, 29 are switched on and off by the switching valves 24, 28 described above.
- a power control of the CAS evaporator takes place, for example, via a conventional thermostatic expansion element 26 (TXV) explained above or via a TXV with integrated shut-off function.
- TXV thermostatic expansion element 26
- the first evaporator in the form of the HVAC evaporator is switched off or bypassed on the refrigerant side via a bypass line 31.
