Abstract

The utility model provides a double-cylinder variable-displacement heat pump air conditioner system, which comprises a double-cylinder variable-displacement compressor, a gas-liquid separator, a Y-shaped three-way valve, a three-way stop valve, an evaporator, a two-way stop valve, a throttle valve, a condenser and an electromagnetic five-way reversing valve. When an air conditioner does refrigeration work, a small cylinder valve plate arranged in the double-cylinder variable-displacement compressor is opened, and the pressure in an external connecting pipe of the compressor is balanced with the pressure in an air return pipe of the compressor, so a small cylinder of the compressor is in an idle load state, and the operation energy consumption of the air conditioner is effectively reduced. When the air conditioner does heating work, the small cylinder valve plate is closed, double cylinders of the double-cylinder variable-displacement compressor simultaneously work, the external connecting pipe of the compressor and the exhaust pipe of the compressor are both in a communicated state, and the heating effect is greatly improved.
