This is typical of coolant being low in the radiator-engine. Let the engine cool overnight, then remove the radiator cap to see if you need to add some coolant. Depending on the type of radiator overflow system, checking the overflow bottle will not always reflect if the radiator is full, especially if there is a slow coolant leak somewhere. Check it at the ...

There is NO free lunch, you will need many batteries and a much better alternator. You could in fact attach a window mounted air conditioner like @Spehro Pefhany suggests. OR TEC Thermo Electric Cooling There are peltier elements that also generate a cooling effect compressor free. They are essentially a plate of ceramic postively charged, and one ...

Yes, this is possible. Several companies (VAG, BMW) have switched to AC units that are driven by electric motors. For BMW, this is part of their Efficient Dynamics strategy, where they'll switch the compressor on/off depending on engine load to optimize fuel consumption. When the weather's not too hot, you can run the compressor intermittently without the ...

Well, Teslas (and presumably other all-electric cars) have A/C so it's not impossible, but A/C takes a fair amount of power. On the other hand, Teslas store a lot of energy. The A/C is something like 2.4kW which is about 8,000 BTU/h or about 3HP. So using an electric motor on a conventional car might give you a few more HP briefly, but the alternator has ...

The short answer to your question is no. As @JPhi1618 noted, the compressor is mechanically driven. Without the compressor you don't have any cooling. The AC runs by changing the state and pressure of a liquid, and compressing the liquid is a big part of that cycle. If you bolted an electric compressor onto the car you would have to find a way to switch ...

I can't give you numbers or calculations without some work, but I can tell you than energy is never free. Cars have an A/C compressor that is mechanically driven by the engine because this is the easiest way to get the job done in a typical consumer car. An A/C compressor actually takes a huge amount of energy to operate. In fact a central A/C unit for a ...

Vent Doors in your HVAC system are not working properly You have various doors in your system to direct air to appropriate places as you change the settings on your dash. When you want air to come out at the floor and you change the setting, a door closes off or opens up appropriately in your system to direct the air to the correct location. The internal ...
