Device for temperature control in a vehicle

Abstract

A device for a temperature control in a vehicle has element forming a first circuit for circulation of a coolant, element forming a second circuit for circulation of a refrigerant, element for connecting the first circuit with an engine for heating the coolant, element for providing a heat exchange between the second circuit and the first circuit for cooling the coolant, an air temperature regulating element, and element for alternatively connecting the first element to the air temperature regulating element so that when the coolant is heated from the engine and supplied through the first element the air temperature regulating element heats air in the vehicle, or connecting the second element with the air temperature regulating element so that when the coolant in the first circuit is cooled by heat exchange with the refrigerant the second circuit the cooled coolant is supplied to the air temperature regulating element to cool air in the vehicle, and element for passing a medium selected from the group consisting of the heated coolant, the cooled coolant, and both to at least one auxiliary device in a vehicle to provide heating or cooling of the auxiliary device.
