Abstract

This invention provides an auxiliary heating and cooling circuit for an automobile interior compartment. The auxiliary circuit uses a circulated liquid heat transfer fluid such as the same liquid used for the vehicle engine system. In a cooling mode, the liquid is circulated through a heat exchanger within the vehicles air-conditioning circuit. The cooled fluid flows to an auxiliary heat exchanger where cooled air is made available. In a heating mode, the auxiliary system is connected directly with the engines cooling system where the hot engine coolant flows through the auxiliary heat exchanger for interior compartment heating.
