Combined cooling and extinguishing system
Various embodiments include a combined cooling and extinguishing system for a motor vehicle, the system comprising: a cooling system circulating carbon dioxide as a coolant, the cooling system including a compressor, an evaporator, an expansion valve; and a condenser; an extinguishing system including a pressure vessel storing compressed CO 2 ; and a control valve connected to the pressure vessel and to the cooling system. The control valve includes a first setting to supply CO 2 from the pressure vessel to the cooling system and a second setting to supply CO 2 from the cooling system to the pressure vessel.
1. A combined cooling and extinguishing system for a motor vehicle, the system comprising:
a cooling system circulating carbon dioxide as a coolant, the cooling system including a compressor, an evaporator, an expansion valve; and a condenser;
an extinguishing system including a pressure vessel storing compressed CO 2 ; and
a control valve connected to the pressure vessel and to the cooling system;
wherein the control valve includes a first setting to supply CO 2 from the pressure vessel to the cooling system and a second setting to supply CO 2 from the cooling system to the pressure vessel.
2. The combined cooling and extinguishing system as claimed in claim 1 , wherein the control valve supplies carbon dioxide to the cooling system if the compressor is not being driven.
3. The combined cooling and extinguishing system as claimed in claim 1 , wherein the control valve closes supply of carbon dioxide to the cooling system if the compressor is being driven.
4. The combined cooling and extinguishing system as claimed in claim 1 , wherein the control valve moves into a closed position if the extinguishing system releases CO 2 for fighting a fire.
5. The combined cooling and extinguishing system as claimed in claim 1 , wherein the control valve supplies carbon dioxide to the pressure vessel if the cooling system is at a steady state.
6. The combined cooling and extinguishing system as claimed in claim 1 , wherein the control valve comprises an overpressure valve, a thermostat valve, or a solenoid valve.
7. A vehicle comprising:
at least one traction surface;
a drive system providing force to the at least one traction surface;
a cooling system circulating carbon dioxide as a coolant, the cooling system including a compressor, an evaporator, an expansion valve; and a condenser;
an extinguishing system including a pressure vessel storing compressed CO 2 ; and
a control valve connected to the pressure vessel and to the cooling system;
wherein the control valve includes a first setting to supply CO 2 from the pressure vessel to the cooling system and a second setting to supply CO 2 from the cooling system to the pressure vessel.
8. The vehicle as claimed in claim 7 , further comprising:
an internal combustion engine; and
a belt drive;
wherein the internal combustion engine drives the belt drive; and
the belt drive rotates the compressor.
