摘要： A heat exchange assembly and a heat exchange device. The heat exchange assembly includes a heat exchanger (10) and a fan (20); the heat exchanger (10) and the fan (20) are spaced apart, and the heat exchanger (10) is located in an air intake direction or an air outgoing direction of the fan (20); the fan (20) includes an air opening (21); a shortest distance H between the air opening (21) of the fan (20) facing the heat exchanger (10) and the heat exchanger (10) and a diameter D of an impeller of the fan (20) should meet 2H/D > 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.

摘要： 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 (1), a rotator (2), an upper flange (3), and a lower flange (4). The rotator (2) is arranged inside the cylinder (1) and is rotatable, a compression chamber (10) is formed between the rotator (2) and an inner peripheral wall of the cylinder (1), a vapor injection opening (5) is defined in the upper flange (3) and/or the lower flange (4), and the vapor injection opening (5) is configured to supply gas outside the compressor to the compression chamber (10) 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. Moreover, increased power consumption caused by using a two-stage cylinder is reduced, thereby improving energy efficiency of a system effectively, greatly reducing a cost and a power of the compressor, and achieving objectives of high capacity, a high energy efficiency and a low cost.

摘要： A heat pump air conditioning system and a control method. The heat pump air conditioning system includes: a compressor (1); an indoor unit heat exchanger (2), an outdoor unit heat exchanger (3) and a throttling device (4); a refrigerant circulation loop, connecting the compressor (1), the indoor unit heat exchanger (2), the outdoor unit heat exchanger (3) and the throttling device (4) in series; the heat storage module (5), disposed in the refrigerant circulation loop and configured to absorb heat from refrigerant in the refrigerant circulation loop and store heat when heat storage defrosting is required, and to heat the refrigerant in the refrigerant circulation loop when the outdoor unit heat exchanger is defrosted. 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 processwhile continuing supplying heat to a room to ensure that room temperature remains unchanged, thereby improving comfort of the room.
