Cooling and heating system for vehicle

摘要

A cooling and a heating system for a vehicle having a refrigerant compressor (12) of a variable displacement type and a viscous heater of a variable heating capacity, which are integrated by a common, intermediate housing, and have a common driving shaft. 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.
