Abstract: An air outlet device, an air conditioning system, and a control method therefor. The air outlet device is for use in an air conditioning system, and includes: an air outlet device for an air conditioning system, including: a heat exchanger that exchanges heat with the air flowing through; a fan device that drives the air to flow through the heat exchanger; a formaldehyde removal part coated with a formaldehyde removal coating that can catalyze the decomposition of formaldehyde into water and carbon dioxide; a housing for accommodating the heat exchanger, the fan device, and the formaldehyde removal part; and a controller for controlling the start and stop of the fan device. According to the air outlet device, the air conditioning system, and the control method therefor of the present application, the air is purified by providing a formaldehyde removal part in the housing of the air outlet device.

Abstract: A refrigeration system and a control method thereof. The refrigeration system includes a compressor and a condenser, and further includes a first throttling device for receiving liquid refrigerant from the condenser; an ejector having a high-pressure fluid inlet, a fluid suction inlet and a fluid outlet, the high-pressure fluid inlet of the ejector is connected to the first throttling device, the fluid outlet of the ejector is connected to a flash tank, a gas-phase outlet of the flash tank is connected to a compressor inlet, a liquid-phase outlet of the flash tank is connected to an evaporator via a second throttling device, and the evaporator is connected to the fluid suction inlet of the ejector; and a controller configured to control an opening of the first throttling device based on a pressure difference between the fluid outlet and the fluid suction inlet of the ejector.
