First Claim
1. A method for operating a device for the thermal conditioning of a motor vehicle interior, comprising:
- exchanging heat with a flow of air configured to be conditioned by a refrigerant circuit comprising a compressor and a heat exchanger forming an evaporator;
diverting, from the heat exchanger and by at least one bypass means, at least part of said flow of air, the at least one bypass means having the ability to be controlled between a closed position, in which no flow is diverted from the heat exchanger, and a plurality of open positions, in which part of the flow is diverted from the heat exchanger on the basis of one of the plurality of open positions;
mixing the flow of air that has passed through the evaporator and the flow of air diverted by the at least one bypass means to obtain the flow of air at a setpoint temperature; and
operating the compressor in a cyclical manner having a period of operation in a first state, in which the compressor generates together with the heat exchanger a first quantity of frigories stored in the first state, alternating with a period of operation in a second state, in which the compressor generates together with the heat exchanger a second quantity of frigories stored in the second state, wherein the second quantity is lower than the first quantity,wherein the position of the at least one bypass means is controlled in a cyclical manner consistent with the first and second state periods of operation of the compressor,wherein the at least one bypass means is controlled in a cyclical manner between an open position among the plurality of open positions and the closed position, andwherein the duration of a period of the open position is longer than the period of operation in the first state of the compressor.
