Problems solved by technology

However, this latent cooling is usually exhausted after a few seconds and is no longer available to cool the interior, especially in motor vehicles
[0004] In order to be able to further achieve a further cooling of the interior and thus further driving comfort for the motor vehicle occupants, the internal combustion engine is usually restarted, which makes it difficult to save fuel

Abstract

The invention relates to a combined cooling and extinguishing system (3) for a motor vehicle. Another claim relates to a motor vehicle with the combined cooling and fire suppression system (3). The combined cooling and extinguishing system (3) includes the cooling system (4), carbon dioxide (CO 2 ) circulates as a coolant inside the cooling system, wherein the cooling system (4) has a compressor (6), an evaporator (8), an expansion valve (7) and a condenser (9). The combined cooling and extinguishing system (3) also includes: extinguishing system (5) with pressure vessel (14), compressed CO 2 stored in the pressure vessel; and a control valve (21) connected to the pressure vessel (14) of the fire extinguishing system (5) and to the cooling system (4) and designed to to put the CO from the pressure vessel (14) 2 conveyed to the cooling system (4) and in the opposite direction to the cooling system (4) of the CO 2 to the pressure vessel (14).

Description

technical field [0001] The invention relates to a combined cooling and fire suppression system for a motor vehicle. Furthermore, a motor vehicle with a combined cooling and fire suppression system is claimed. Background technique [0002] A cooling system or air conditioning system for a motor vehicle usually includes a compressor, an expansion valve, an evaporator and a condenser. A coolant circulates inside the air conditioning unit, this coolant can especially be carbon dioxide (CO 2 ). CO 2 Also known as refrigerant R744. CO 2 Can be compressed by the compressor inside the air conditioner. The compressor is usually driven by a belt drive, which in turn is driven by the internal combustion engine of the motor vehicle. In known motor vehicles, especially hybrid vehicles, a motor shutdown function is provided in order to reduce the fuel consumption of the motor vehicle. [0003] However, as mentioned above, the compressor of the air conditioning system is usually co...
