Abstract
A vehicle air conditioning system includes a compressor, a condenser, an evaporator and a thermoelectric device. The compressor is configured to receive a refrigerant and compress the refrigerant to a compressed state. The condenser is in fluid communication with the compressor to receive the refrigerant in the compressed state via a high pressure tube. The evaporator is in fluid communication between the condenser and the compressor to receive the refrigerant from the condenser and convey the refrigerant to the compressor via a low pressure tube. The thermoelectric device is operatively arranged relative to at least a portion of the high pressure tube to remove heat from the high pressure tube.

A vehicle air conditioning system comprising:
- a compressor configured to receive a refrigerant and compress the refrigerant to a compressed state;
- a condenser in fluid communication with the compressor to receive the refrigerant in the compressed state via a high pressure tube;
- an evaporator in fluid communication between the condenser and the compressor to receive the refrigerant from the condenser and convey the refrigerant to the compressor via a low pressure tube;
- and
- a thermoelectric device operatively arranged relative to at least a portion of the high pressure tube to remove heat from the high pressure tube, the thermoelectric device contacting at least a portion of the low pressure tube to dissipate heat from the thermoelectric device to the portion of the low pressure tube.
