Use of pve lubricants with substitute refrigerants in a mobile air conditioning system

A mobile air-conditioning system for use in a vehicle, the system comprising:

• a compressor, wherein the compressor includes one of a mechanically driven compressor and an electrically driven compressor;
• and
• a heat transfer composition, wherein the composition comprises:
• a first component including a hydrofluoroolefin refrigerant;
• a second component including a polyvinyl ether lubricant;
• and
• wherein the heat transfer composition is compatible for use in the mobile air-conditioning system when the mobile air-conditioning system is powered by a mechanically driven compressor, and further wherein the heat transfer composition is compatible for use in the mobile air-conditioning system when the mobile air-conditioning system is powered by an electrically driven compressor.

• and
• a heat transfer composition, wherein the composition comprises:
• a first component including a substitute refrigerant of the HFO-1234yf type;
• a second component including a polyvinyl ether lubricant;
• and
• wherein the heat transfer composition has a resistivity of about 1×1014 ohm-cm and is compatible for use in the mobile air-conditioning system when the mobile air-conditioning system is powered by a belt driven compressor, and further wherein the heat transfer composition is compatible for use in the mobile air-conditioning system when the mobile air-conditioning system is powered by an inverter driven compressor.
