To Use Max AC or AC. If I understand properly, setting your vehicle in the AC setting will cycle air from the outside into your vehicle attempting to cool it before it is pulled in. Likewise, MAX AC only recycles the cabin air not pulling in any air from "under the hood."

Follow-Up #1: car acceleration You're right that the maximum acceleration for some cars can be in the neighborhood of g, 9.8 m/s2. That means that the coefficient of friction, μ, has to be around 1 or so.

When choosing an air conditioner, usually a 1 HP (horse power) equipment is able to remove 9,000 BTU/hr of heat. With better technology, some machines are able to remove 10,000 BTU/hr of heat with the same capacity. The higher the listed BTU/hr, the greater the cooling capacity.

In this car, the controller takes in 300 volts DC from the battery pack. It converts it into a maximum of 240 volts AC, three-phase, to send to the motor. It does this using very large transistors that rapidly turn the batteries' voltage on and off to create a sine wave.

Car manufacturers recommend that your air conditioning system is recharged with gas and lubricant every 2 years. This does not come as part of your annual vehicle servicing. So, if your vehicle is older than 2 years, it is quite likely to be due an air conditioning recharge.

Generally, air conditioning works the same for all cars. All systems run on a high-pressure gas called refrigerant. No matter the make, the air conditioning system uses the following parts: Compressor: Compresses the refrigerant into a fluid, so the refrigerant flows through a line to the condenser.

ISO relays are usually rated at 30 Amps but in fact, because this is a rating for use at the maximum under-bonnet (hood) temperature found in modern cars of 135ºC (150ºC in Europe), in most locations in LBC's they have greater current capability.

Cranking amps are the numbers of amperes a lead-acid battery at 32 degrees F (0 degrees C) can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12 volt battery). In other words, CA/cranking amps determine how much power you have to start your car in most climates.

The HVAC system is an important accessory, and helps you stay cool in the car when it gets hot outside. However, the AC is powered by your engine – the serpentine belt that runs your alternator, water pump, power steering pump and other accessories also turns the pulley for the AC compressor/clutch.

How NASCAR drivers survive racing without A/C. ... But the cars don't have built-in air conditioning. Seriously. It's just one of the many ways stock cars are different from passenger cars, and a traditional air conditioning system would add a significant amount of extra weight.

Yes — like many of your car's features, the air conditioning system uses gas. The air conditioner draws energy from the alternator, which is powered by the engine.

In the case of air conditioning it extracts heat from the passenger compartment in a vehicle and releases it into the atmosphere. It does this by the refrigerant in the air conditioning system absorbing the heat and then releasing it again.
