If you mean an "orifice tube", then yes.

Some units use orifice tubes and some units use thermostatic expansion valves to meter the refrigerant, but in either case it will be found between the condensation coil and the evaporator coil. Usually just before entering the evaporator coil.
No use for exhaust in car air conditioning
I have 1998 chev suburban with rear air do they use two orifice tubes
yes.
The air conditioning drain is on the passenger's side of the firewall. If you do not have air pressure to blow into it to get it to drain then you might use something soft and flexible so as not to put a hole in the evaporator.
The concept of air conditioning has been in use since the time of the Ancient Egyptians. The first modern electric air conditioning device was invented in 1902 by Willis Carrier.
A '99 Olds Delta 88 doesn't use an orifice tube system for the air conditioning it uses a thermal expansion valve. The location is under the passenger side dash in the heater/evaporator box. Unfortunately, you have to remove the dash to replace it as well as discharge the a/c system.
Air conditioning is removing hot air with cold air. For example we use air conditioner that removes hot air by blowing cold air from a refrigeration cycle into a room.
Air conditioning involves the transformation of electrical energy into thermal energy. The electrical energy is used to power the air conditioning unit, which then removes heat from the indoor air, cooling it down.
Central air conditioning systems do not use water for cooling. Instead, they use refrigerants to transfer heat from inside a building to the outside.
you get a big electric bill.
