초록 ▼

A heat pump type air conditioner for a vehicle has a refrigeration cycle constituted by a compressor, an external heat exchanger, a refrigerant valve unit and an internal heat exchanger unit. The refrigerant valve unit includes first and second flow control valves, and the internal heat exchanger unit includes an auxiliary internal heat exchanger and a main internal heat exchanger. In the refrigeration cycle, the first flow control valve, the auxiliary internal heat exchanger, the second flow control valve and the main internal heat exchanger are serially connected in the order of mention. The main and auxiliary internal heat exchangers change their function between an evaporator and a condenser according to the controlled state of the first and second flow control valve.

1. A heat pump type air conditioner for a vehicle executing a heating operation and a cooling operation according to a temperature condition, said heat pump type air conditioner comprising:refrigerant; a compressor applying workload to said refrigerant; an external heat exchanger connected to an outlet of said compressor; a bypass passage connecting a refrigerant inlet and a refrigerant outlet of said external heat exchanger; a flow mode selector that selects a heating flow mode when the heating operation is executed and selects a cooling flow mode when the cooling operating is executed, said refrigerant flowing through said bypass passage without flowing through said external heat exchanger when the heating flow mode is selected, said refrigerant flowing through said external heat exchanger without flowing through said bypass passage when the cooling flow mode is selected; a first flow control valve connected to the refrigerant outlet of said external heat exchange, said first flow control valve being an electromagnetic valve which comprises a valve body having a port through which said refrigerant flows, a valve opening and closing the port according to an electrical signal, and a choked portion through which said refrigerant restrictedly flows when the port is closed by said valve; an auxiliary internal heat exchanger connected to an outlet of said first flow control valve; a second flow control valve connected to a refrigerant outlet of said auxiliary internal heat exchanger; a main internal heat exchanger connected to an outlet to said second flow control valve, a refrigerant outlet of said main internal heat exchanger being connected to an inlet of said compressor; air delivering means for passing air through said main and auxiliary internal heat exchangers and delivering the air to a passenger compartment of the vehicle; a sub heat exchanger connected to the refrigerant outlet of said main internal heat exchanger and the inlet of said compressor, said sub heat exchanger being arranged to heat said refrigerant by means of engine coolant of a vehicular engine; a heater core which is connected to the vehicular engine so that the engine coolant circulates said heater core, said heater core being disposed in said air delivering means and downstream of said main and auxiliary internal heat exchangers; and an air-mix door disposed between said auxiliary internal heat exchanger and said heater core, said air-mix door controlling a quantity of the air passing through said heater core.
