摘要： Disclosed in the present invention are a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises a cold accumulation tank, and a condensation tank accommodating the cold accumulation tank. The cold accumulation tank stores a quantity of cold by means of a cold accumulation material. The condensation tank is used for separating a gas mixture of gaseous refrigerant and non-condensable gas exiting the system into liquid refrigerant and non-condensable gas, by causing the gas mixture of gaseous refrigerant and non-condensable gas to undergo heat exchange with the cold accumulation material in the cold accumulation tank; the isolated liquid refrigerant is led into the system, and the isolated non-condensable gas is discharged from the condensation tank. The method comprises a cold accumulation process, a condensation process, a gas discharge process and a liquid discharge process.

摘要： The present invention provides a gas discharge device for discharging non-condensable gas in a refrigeration and air conditioning system, and a method thereof. The gas discharge device comprises an evaporative condenser, which isolates liquid refrigerant and non-condensable gas by condensing a gas mixture of gaseous refrigerant and non-condensable gas exiting the refrigeration and air conditioning system, and leads the isolated liquid refrigerant into the refrigeration and air conditioning system, but discharges the isolated non-condensable gas. The method comprises an evaporative condensation process, a gas discharge process and a liquid discharge process. The present invention can prevent the accumulation of non-condensable gas in a condenser of a refrigeration and air conditioning system, and thereby helps to guarantee the refrigerating capacity and energy efficiency of the refrigeration and air conditioning system, such that it operates safely and efficiently.

摘要： A fan, comprising blades (102), an upper hub (111), and a lower hub (112). Each blade (102) comprises a connecting part (211). The connecting part (211) is clamped between a lower surface of the upper hub (111) and an upper surface of the lower hub (112). The lower surface of the upper hub (111) is provided with an upper hub connecting area, and the upper surface of the lower hub (112) is provided with a lower hub connecting area. An upper surface and a lower surface of the connecting part (211) are separately provided with a junction surface extending from the connecting part (211). The lower surface of the upper hub (111) and the upper surface of the lower hub (112) are separately provided with a matching surface matching the junction surface. The junction surface and the matching surface are arranged in the radial direction and/or circumferential direction of the upper hub (111) and the lower hub (112), and are configured to match with each other to impede the movement of at least two blades (102) in the circumferential direction and/or radial direction with respect to the upper hub (111) and the lower hub (112). The fan structure can prevent the movement of the blades (102) with respect to the upper hub (111) and the lower hub (112). The connecting part (211) and the fan body (201) are not easy to break and can be easily assembled, such that better stability can be ensured while the cost is low.
