Abstract
Vehicle climate control system and method for control of the vehicle climate control system for temperature regulation of a vehicle battery, the vehicle climate control system includes a refrigerant circuit containing at least a compressor, a gas cooler/condenser, an expansion element, an evaporator, as well as refrigerant lines to connect the components, wherein an intermediate expansion element is arranged upstream from the expansion element in the refrigerant flow direction and a heat exchanger for the temperature regulation of a vehicle battery is arranged between the expansion elements.
Claims8
A vehicle climate control system comprising:
- a refrigerant circuit having components a compressor, a gas cooler/condenser, an expansion element, an evaporator, and refrigerant lines connecting the components;
- an intermediate expansion element arranged upstream from the expansion element in a refrigerant flow direction;
- and
- a heat exchanger for temperature regulation of a vehicle battery arranged between the expansion element and the intermediate expansion element.
A method for heating or cooling of a vehicle battery with a climate control system, the method comprising the steps of:
- providing a refrigerant circuit having components a compressor, a gas cooler/condenser, an expansion element, an evaporator, and refrigerant lines connecting the components, an intermediate expansion element arranged upstream from the expansion element in a refrigerant flow direction, and a heat exchanger for temperature regulation of a vehicle battery arranged between the expansion element and the intermediate expansion element;
- and
- adjusting an intermediate pressure in the refrigerant circuit for the heat exchanger with the intermediate expansion element, wherein the intermediate pressure in the refrigerant circuit is controlled in dependence on at least one of a required and a desired temperature of the vehicle battery.
