a compressor disposed in the first vehicle chamber and disposed in the circulating path, and an evaporator disposed in the second vehicle chamber and disposed in the circulating path, the evaporator comprising a meandering flattened pipe; a first header joined with one end of the flattened pipe for introducing the compressed refrigerant from the compressor to the flattened pipe; and a second header joined with the other end of the flattened pipe for receiving the refrigerant from the flattened pipe and for discharging the refrigerant toward the compressor, wherein both headers are disposed in the first vehicle chamber, and the meandering flattened pipe has opposite ends located in the first vehicle chamber.
2. The vehicle air-conditioning system according to claim 1 , wherein the flattened pipe is a continuous pipe without joints and the flattened pipe is joined to the first and second header in the first vehicle chamber.
3. The vehicle air-conditioning system according to claim 1 , further comprising a condenser and a throttling device, each of which is disposed in the first vehicle chamber, wherein the condenser and the throttling device are disposed in the circulating path between the compressor and the evaporator.
4. The vehicle air-conditioning system according to claim 1 , wherein the refrigerant is HFC-152a.
5. The vehicle air-conditioning system according to claim 3 , further comprising an oil separating and recovering device for separating the refrigerant and lubricating oil and recovering and returning the lubricating oil to the compressor, disposed in the first vehicle chamber, wherein the oil separating and recovering device is disposed proximate to the discharge opening of the compressor.
6. The vehicle air-conditioning system according to claim 5 , wherein the oil separating and recovering device is disposed between the compressor and the condenser.
7. The vehicle air-conditioning system according to claim 1 , further comprising an oil separating and recovering device for separating the refrigerant and lubricating oil and recovering and returning the lubricating oil to the compressor, disposed in the first vehicle chamber, wherein the oil separating and recovering device is disposed proximate to the discharge opening of the compressor.
