Claims (1)

[Scope of utility model registration request] A rolling piston type variable capacity compressor that has two coaxial cylinders, one inlet and one outlet, and the inflow of gas into each cylinder can be controlled by a slide valve moved by an electromagnetic coil. In an automotive air conditioning system that uses a condenser, receiver dryer, expansion valve, and evaporator in series and is powered by the main engine of a portable vehicle, the compressor electromagnetic clutch O is activated at the start of cooling operation.
In order to reduce the shock to the main engine due to N, the system is characterized by starting operation with the flow of refrigerant gas to one cylinder always stopped, and after a certain set time, starting operation with two cylinders of the compressor. Automatic military air conditioner.
