Heat exchange assembly, control method thereof and air conditioner

Abstract

The invention provides a heat exchange assembly and a control method thereof and an air conditioner. The heat exchange assembly comprises a heat exchange tube, an inlet tube and an adjusting part, wherein at least two inlets are formed in the tube wall of the inlet tube, and each inlet communicates with a flow supply tube; the flow supply tube communicates with the heat exchange tube; the flow supply tube is used for guiding a heat exchange medium in the inlet tube to flow into the heat exchange tube for heat exchange; the adjusting part is arranged on the inlet tube and can move to adjust the number of the open inlets. According to the heat exchange assembly, the control method thereof and the air conditioner, under the condition that production and maintenance cost is not increased, the cooling capacity or heating capacity adjusting range of a fan unit is widened.

Description

technical field [0001] The application belongs to the technical field of air conditioners, and in particular relates to a heat exchange component, a control method thereof, and an air conditioner. Background technique [0002] At present, the fan coil water system with one supply pipe and one return pipe is called a double water pipe system, which is similar to the hot water heating system of mechanical circulation. Cold water in summer and hot water in winter. At this time, the structure of the fan coil unit is single, the form and number of flow channels of the coil unit are relatively uniform, and the cooling capacity of the unit is mainly solved by the water flow. [0003] However, the water flow of the fan coil unit cannot be infinitely small or infinitely large. If the water flow is too small, the resistance of the fan coil unit is too large, and the water flow can be too large. The flow rate is adjusted within a small range, so the adjustment range of the cooling ca...

AI Technical Summary

Problems solved by technology

At this time, the structure of the fan coil unit is single, the form and number of flow channels of the coil unit are relatively uniform, and the cooling capacity of the unit is mainly solved by the water flow.

[0003] However, the water flow of the fan coil unit cannot be infinitely small or infinitely large. If the water flow is too small, the resistance of the fan coil unit is too large, and the water flow can be too large. The flow rate is adjusted within a small range, so the adjustment range of the cooling capacity is also very small

When the heating and cooling capacities of the hot water coil and the cooling coil do not overlap, most of the methods are to set up two coils (hot water coil and cold water coil) in one unit for cooling in summer. , heating in winter, this method increases the production and maintenance costs of a coil
