Abstract: This temperature regulation apparatus comprises a heat pump (12) comprising a main compression circuit (14) for a refrigerant fluid taking heat from a cold source (16) and transferring it to a hot source (18). The cold source (16) comprises a first heat exchanger (24) for exchanging heat between the refrigerant fluid and a liquid coolant thermally coupling the main refrigerant circuit (14) to a first secondary coolant circuit (26). The first secondary circuit (26) has selective connection means (40, 52, 54) for selectively connecting it to the upstream and downstream ends (48A, 48B) of a “heater” branch (48) of a cooling liquid circuit (46) of an exothermal part of the vehicle. The exothermal part is preferably a heat engine of the vehicle. The invention is applicable to air conditioning a motor vehicle cabin.

Abstract: According to the method, heat delivered to the cabin (H) comes from a hot source (18) of a heat pump (12) comprising a main refrigerant circuit (14) taking heat from a cold source (16) to transfer it to the hot source (18). Heat taken from the cold source (16) comes from a flow of air recycled from the cabin. The cold source (16) has a refrigerant/coolant heat exchanger (24) thermally coupling the main circuit (14) to a first secondary coolant circuit (26) capable of being selectively connected to an outside heat exchanger (30) and to a cold heat exchanger (32). Air flow circuits have an inlet for admitting air recycled from the cabin, an outlet for delivering air to the outside of the vehicle, first connection means for connecting the recycled air inlet to the upstream end of the cold heat exchanger (32), and second connection means for connecting the downstream end of said cold heat exchanger (32) to the outside outlet.

The refrigerant loop and coolant loop can also operate together where the air conditioning system is operating as a heat pump and drawing heat from the coolant loop.

Abstract: A method of automatically operating a machine with respect to an object having a desired profile, wherein the machine's operation is controlled based on a model of the object's profile. The method includes generating at least a portion of the model in the form of a plurality of successive layers wherein the cross-section of each layer is defined by the intersection of a pair of parallel planes and a model profile connecting the parallel planes. Each layer's thickness is selected such that the geometrical error between the object's desired profile and the model profile of the layer remains no greater than a preselected geometrical error. More than one layer thickness is selected during the step of generating this portion of the object. The machine can be operated in successive steps with each step based on a separate one of the layers.
