Maybe a clogged heater core!
Air in the cooling system. Look up bleeding cooling system.
Heat removal in the design of this new cooling system is managed through the use of efficient heat exchangers and fans that help dissipate heat away from the system. Additionally, the system may incorporate advanced cooling technologies such as liquid cooling or phase-change cooling to enhance heat removal capabilities.
Refrigerant absorbs heat in a cooling system by circulating through the system and changing from a liquid to a gas state. As it evaporates, the refrigerant absorbs heat from the surrounding air or water, cooling the area.
They are probably not working because they are most likely broken.
No!
There are many places where you can find an entire picture of cooling system and heat. You could look online for example.
heat transfer by convection Heat lost by the water = Heat gain by the air
heat transfer by convection Heat lost by the water = Heat gain by the air
Air trapped in the system, defective water pump, blown head gasket or cracked head, cooling fan not working properly.Air trapped in the system, defective water pump, blown head gasket or cracked head, cooling fan not working properly.
Blockage in the cooling system No or little fluid in the cooling system Radiator fan not working
No. If the A/C is not working there is a problem related to the A/C system. A thermostat is in the cooling system and if its not working properly the vehicle can overheat or not get warm enough to give you heat inside the vehicle.
A heat pump uses a refrigerant to transfer heat from one place to another, providing both heating and cooling. A heat recovery system captures and reuses waste heat for heating or cooling. Heat pumps are generally more efficient for heating and cooling purposes compared to heat recovery systems because they can provide both heating and cooling functions.
