A single-stage enthalpy enhancing rotary compressor and an air conditioner having same. The single-stage enthalpy enhancing rotary compressor includes: at least one single-stage cylinder, a rotator, an upper flange, and a lower flange. The rotator is arranged inside the cylinder and is rotatable, a compression chamber is formed between the rotator and an inner peripheral wall of the cylinder, a vapor injection opening is defined in at least one of the upper flange the lower flange, and the vapor injection opening is configured to supply gas outside the compressor to the compression chamber directly. According to the present disclosure, two-stage compression is realized without adding an extra cylinder, thereby effectively enhancing a circulation of refrigerant, improving cooling performance of the air conditioner under high environmental temperatures.

A heat exchange assembly and a heat exchange device. The heat exchange assembly includes a heat exchanger and a fan; the heat exchanger and the fan are spaced apart, and the heat exchanger is located in an air intake direction or an air outgoing direction of the fan; the fan includes an air opening; a shortest distance H between the air opening of the fan facing the heat exchanger and the heat exchanger and a diameter D of an impeller of the fan should meet 2H/D&#x3e;1.05. A problem in the prior art of increased air intake resistance caused by an improperly arranged distance between the heat exchanger and the fan is solved.

A heat pump air conditioning system and a control method. The heat pump air conditioning system includes: a compressor; an indoor unit heat exchanger, an outdoor unit heat exchanger and a throttling device; a refrigerant circulation loop, connecting the compressor, the indoor unit heat exchanger, the outdoor unit heat exchanger and the throttling device in series; the heat storage module, disposed in the refrigerant circulation loop and configured to absorb heat from refrigerant in the refrigerant circulation loop and store heat when heat storage is required, and to heat the refrigerant in the refrigerant circulation loop when the outdoor unit heat exchanger defrosting is required. The heat pump air conditioning system can store excess heat of the system for defrosting when indoor heat load is low, and release heat for defrosting by means of the heat storage module during a defrosting process while continuing supplying heat to a room.

An exhaust bearing seat, a screw compressor and an air-conditioning unit are provided. The exhaust bearing seat is provided with a discharge port, wherein an opening of the discharge port is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside the housing, and facilitates the reduction of noise of the gas flow pulsation.
