Embodiment Construction

[0031] The first object of the present invention is to provide an air-conditioning unit and a shell-and-tube heat exchanger. The structural design of the air-conditioning unit and the shell-and-tube heat exchanger can effectively solve the problem of the reduction in the heat transfer performance of the condenser and the overheating of the heat exchange tubes 7. To solve the problem of insufficient cooling, the second object of the present invention is to provide a heat exchange method for a shell-and-tube heat exchanger.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative ef...

Abstract

The invention discloses an air conditioning unit, a shell and tube heat exchanger and a heat exchange method of the shell and tube heat exchanger. The shell and tube heat exchanger comprises a housing, a heat exchange tube as well as a vibrator, wherein the heat exchanger and the vibrator are positioned inside the housing; and the vibrator can drive the heat exchange tube to vibrate. The vibrator drives the heat exchange tube to vibrate, so that too much liquid-state refrigerant is prevented from being adhered on the heat exchange tube below to form a liquid film, and therefore, the conditions that heat exchange performances of a condenser are reduced, and the heat exchange tube is super-cooled insufficiently are avoided.

Description

technical field [0001] The invention relates to the technical field of refrigeration, and more specifically relates to an air conditioner unit, a shell-and-tube heat exchanger and a heat exchange method for the shell-and-tube heat exchanger. Background technique [0002] During the operation of the air conditioning unit, the gaseous refrigerant needs to go through three processes of condensation, cooling and supercooling after entering the condenser. For the shell-and-tube heat exchanger, the gaseous refrigerant will first condense into a gas-liquid mixed state after entering the shell-and-tube heat exchanger, in which the liquid refrigerant will drip downward, and part of the liquid refrigerant will drip to and adhere to the heat exchanger below A layer of liquid film is formed on the tube, and the gradual thickening of the liquid film will increase the heat transfer resistance of the outer surface of the heat exchange tube and reduce the heat transfer coefficient, thereby ...
