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 consist

Abstract: In a device for air temperature control in a vehicle either by use of a valve unit to control a portion of coolant and thereby the temperature of air flowing from the temperature control element, by a temperature of coolant controlled by said thermostat, or by speed of said fan, individually and independently from one another.
