Patent

CA 2204843

A cooling and a heating system for a vehicle having a refrigerant compressor of a variable displacement type and a viscous heater of a variable heating capacity, which are integrated by a common, intermediate housing. A space needed for an installation into an engine compartment of a vehicle is saved, while the production cost is reduced. Furthermore, a requirement for reduction of a fuel consumption efficiency in a low outside air temperature condition and a degradation of a lubricant in high outside air temperature condition, which are otherwise contradictory, are harmonized.

Système de refroidissement et de chauffage muni d'un compresseur de réfrigération à cylindrée variable et d'un réchauffeur à viscosité de puissance calorifique variable, intégrés au moyen d'un boîtier intermédiaire commun. On économise de l'espace dans le compartiment moteur d'un véhicule, tout en réduisant le coût de production. De plus, on harmonise ainsi des exigences contradictoires en matière de réduction du rendement de énergétique du carburant à une température extérieure basse et de dégradation du lubrifiant à une température extérieure élevée.
