The ice accumulator unit is comprised of a vaporizer with an expansion organ and an ice accumulator surrounding the latter. Furthermore, a further vaporizer with an expansion organ is connected in parallel to the at least one ice accumulator unit, wherein it can be controlled by means of respective switching valves, if the refrigerant flows through the further vaporizer or the vaporizer of the ice accumulator unit. The compressor is mechanically driven by a driving motor of the vehicle and can be coupled with the latter by means of a magnetic clutch via a fan belt.
- It is the object of the invention to provide a compact air conditioning system which is adapted to cool a vehicle in a stationary operation of the vehicle.
- The invention is characterized by an air conditioning system for a vehicle having a first refrigerant circuit which comprises an electrically driven compressor, a condenser, an expansion valve and a latent cold storage the heat of which is drawn by means of the refrigerant circuit, and having means for cooling air which is formed such that heat is drawn from the air and the heat is supplied to the latent cold storage. By means of the electrically driven compressor, the power of the compressor can be adjusted independently of the rotational speed of a driving shaft of the vehicle and, if necessary, the compressor can also be provided with electrical energy independently of the drive of the vehicle. Thereby, a predetermined amount of heat can be drawn from the latent cold storage in a simple manner also during extreme hotness.
- If a further primary air conditioning system is disposed in the vehicle, the compressor of which is driven by the driving shaft of the vehicle, for example, by the crank shaft, the charging of the latent cold storage of the air conditioning system can also be affected quickly when the compressor of the primary air conditioning system is operated at its maximal capacity.
- The latent cold storage is characterized by a very high specific cold capacity. This has the advantage that the air conditioning system can be formed very compact. In particular, it can draw a high amount of heat from the air in the stationary operation of the vehicle when the driving shaft does not rotate.
- In an advantageous formation of the invention, the air conditioning system hast a refrigerant circuit which comprises a pump, the latent cold storage and a heat exchanger by means of which heat is drawn from the air and the heat is then supplied to the latent cold storage. This has the advantage that the heat exchanger can be disposed at any position in the vehicle.
- In a further advantageous formation of the invention, a blower is assigned to the heat exchanger which influences the air flow through the heat exchanger and simultaneously influences the air flow through a heating element. This has the advantage that only one blower is necessary for cooling the air, on the one hand, and for heating the air, on the other hand.
- In particular, it is advantageous when the heating element is a heating heat exchanger through which a fluid flows which can be heated by means of a fuel heating device. With a heating element formed in such a manner a notably high heating power is possible.
- In a further advantageous formation of the invention, the latent cold storage is disposed such that the air to be cooled flows through the latent cold storage and, at the same time, is cooled by the latter. Thus, the air conditioning system can be formed notably compact. In this context, it is notably advantageous when the refrigerant circuit comprises a plurality of latent cold storages. Accordingly, cooling at many positions of the vehicle can be affected. In particular, this is advantageous in motor trucks which have, besides a driver compartment, a sleeping/living compartment formed separately of the latter.
- In a further advantageous formation of the invention, a generator is assigned to the air conditioning system which is driven by a driving shaft of a drive of the combustion engine and thus, provides the electrical energy of the electrically driven compressor. In such a manner, the electrical driven compressor can be operated with high power during the driving operation.

FIG. 1 shows a first embodiment of the air conditioning system, -
FIG. 2 shows a second embodiment of the air conditioning system, -
FIG. 3 shows a third embodiment of the air conditioning system, -
FIG. 4 shows a fourth embodiment of the air conditioning system, -
FIG. 5 shows a fifth embodiment of the air conditioning system, and -
FIG. 6 shows a sixth embodiment of the air conditioning system. - Elements of the same construction and function are identified with the same reference numerals in all figures of the drawings.
- An air conditioning system (
FIG. 1 ) is disposed in a vehicle, in particular, in a motor truck. The air conditioning system has a refrigerant circuit 1 which comprises an electrically drivencompressor 2, acondenser 4 which has assigned acondenser blower 6 thereto, anaccumulator 8, anexpansion valve 10 and a latentcold storage 12. - The
expansion valve 10 can be controlled or can merely be formed as a flow restrictor. The output of thecompressor 2 is connected to thecondenser 4 via afirst line 14 and the output of thecondenser 4, in turn, is connected to theaccumulator 8 via asecond line 16 which, preferably, also comprises a drier. Theaccumulator 8 is connected with theexpansion valve 10 via athird line 18, and the output of theexpansion valve 10 is connected to the latent cold storage via afourth line 20. The output of the latentcold storage 12 is connected to the intake of thecompressor 2 via afifth line 22. The electrically drivencompressor 2 is, preferably, supplied with electrical energy from agenerator 24 which is driven by adriving shaft 26 of adrive 28 of the vehicle. For example, thedrive 28 can be a combustion engine. However, the electrically drivencompressor 2 can also be supplied with electrical energy in another way, for example, by means of a fuel cell or any elements outputting electrical energy, for example, a battery. Also, the electrically drivencompressor 2 can be supplied with electrical energy by any combination of the elements mentioned above. By a respective dimensioning of these elements, the electrically drivencompressor 2 can be operated with a power which is sufficient also under extreme operating conditions in order to draw the desired amount of heat from the latentcold storage 12. - During the operation of the electrically driven
compressor 2, the refrigerant which can be, for example, R134a or also CO2, is compressed, whereby its temperature increases. Thecondenser 4 is formed in cooperation with thecondenser blower 6 such that heat is drawn from the refrigerant by the air flowing through thecondenser 4. - The thus cooled and liquefied refrigerant flows further to the
accumulator 8 via thesecond line 16, and then, to theexpansion valve 10 via thethird line 18 by means of which it is expanded to a lower pressure, wherein the temperature of the refrigerant decreases significantly. Subsequently, the refrigerant flows to the latentcold storage 12, and there, draws heat from the cold storage medium by vaporizing it. The refrigerant which is then gaseous again flows further to the electrically drivencompressor 2 via thefifth line 22 and, there, is compressed again. - The high specific cold capacity of the latent
cold storage 12 results from the fact that the cold storage medium in the latent cold storage draws energy by means of the refrigerant such that a phase transition from a liquid state to a solid state occurs. Thus, the latent cold storage can be compact. Furthermore, it can be produced inexpensively. - When the refrigerant is CO2, it is preferred that the
condenser 4 is a gas cooler and thelines line 22. - The air conditioning system comprises a
refrigerant circuit 30 which has aheat exchanger 32, apump 34 and a latentcold storage 12. The latentcold storage 12 is connected to theheat exchanger 32 via asixth line 36, the output of which is connected with the intake of thepump 34 via aseventh line 38. The output of thepump 34 is connected with to the latentcold storage 12 via aneighth line 40. - Preferably, the
pump 34 is electrically driven and, for example, can obtain the electrical energy necessary for it from a battery not shown. Thepump 34 pumps the refrigerant of the refrigerant circuit through the latentcold storage 12, wherein the latentcold storage 12 is supplied with heat and is cooled in this manner. The cooled refrigerant then pours or flows to theheat exchanger 32 through thesixth line 36 which is supplied with air by ablower 42 in a controlled manner which then delivers the heat to theheat exchanger 32, and thus, is cooled and contributes to the desired cooling of the internal space of the vehicle. Theheat exchanger 32 can be disposed in the region of the passenger compartment or can also be disposed in a sleeping or living room of the vehicle. The heat delivered from the flowing air heats the refrigerant in theheat exchanger 32, and thus, the heated refrigerant flows to thepump 34 via theseventh line 38 where it is pumped again to the latentcold storage 12. - It is preferred that the electrically driven
compressor 2 is operated during the driving operation of the vehicle, and thus, heat is drawn from the latentcold storage 12. Dining the stationary operation of the vehicle, it is preferred that thecompressor 22 is not operated, or at the most, is operated with a low electrical power. In the stationary operation, thepump 34 is driven dependent on the required cooling power, and accordingly, air is cooled in the vehicle by means of therefrigerant circuit 30. - In a second embodiment of the invention (
FIG. 2 ), in addition a heating element is provided which is aheating heat exchanger 44, wherein fluid, preferably a water glycol mixture, is flowing through the latter which can be heated by means of afuel heating device 46 and is supplied to theheating heat exchanger 44 via aninth line 48. Theheating heat exchanger 44 is disposed such that theblower 44 also controls the air flowing through theheating heat exchanger 44. Thus, simply with oneblower 44, the air flowing through both theheating heat exchanger 44 and the air flowing through theheat exchanger 32 can be controlled. - In a third embodiment of the air conditioning system (
FIG. 3 ), anair heating element 50 is provided which, for example, can be formed as a PTC-resistance element, and thus, transforms electrical energy to heat and which is disposed such that the amount of air which flows next to theair heating element 50 is controlled by means of theblower 42. For example, theair heating element 50 can be formed as fuel air heating device. - In a fourth embodiment of the air conditioning system (
FIG. 4 ), theblower 42 is assigned to the latentcold storage 12 and the air to be cooled flows through the latent cold storage or flows next to cooling fins which are assigned to the latter and, thus, delivers heat to the latentcold storage 12 and is thus cooled. In this way, the air conditioning system can be formed notably compact, since therefrigerant circuit 30 can be omitted, in particular when at the plurality of positions of the vehicle, a cooling of the air has to be affected, it is advantageous in this context when the air conditioning system comprises a plurality of latentcold storages 12. This plurality of latentcold storages 12 can then be disposed at respective positions of the vehicle, for example the latentcold storage 12 in a motor truck can be disposed in the passenger compartment and the further latentcold storage 12 can be disposed in a sleeping and/or living room which is separately formed from the latter. - In the fourth embodiment of the air conditioning system, the
fuel heating device 46 and theheating heat exchanger 44 or theair heating element 50 according to the embodiments ofFIGS. 2 & 3 can also exist. - In a fifth embodiment of the air conditioning system (
