Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] It includes a cooling air pipeline and a cooling air pipeline, and the two channels are not connected to each other, and each takes its own path. The cooling air pipeline is composed of 3 to 6 cold sides of heat exchange units 5 connected in series with the pipelines. In this embodiment, there are 5 heat exchange units, and each heat exchange unit is vertically arranged at intervals. The air inlet and outlet ends are connected by diversion elbow 2 and are connected in series with each other. One end of the bottom heat exchange unit is connected to the hot side air inlet pipe 11, which is the hot side air inlet end, and one end of the uppermost heat exchange unit is the hot side. The air outlet is connected to the hot side air outlet pipe 10 to form a cooling air pipeline; the heat exchange unit 5 is a plate-fin heat exchange unit, including a shel...

Abstract

The invention relates to an air-air heat exchanger for refrigeration using water and air as a mixed working medium, which includes a cooling air pipeline and a cooling air pipeline, and the cooling air pipeline is composed of a heat exchange unit hot side and a pipeline The heat exchange unit is connected in series, and the cold side of the heat exchange unit is connected in the cooling air pipeline. The spray nozzle is connected to the high-pressure water source. The heat exchange unit is a plate-fin heat exchange unit, which is installed in a fork-countercurrent heat exchange manner; the cooling air pipeline is in a negative pressure shape. The present invention proposes the design concept of using water and air as the mixed working medium for refrigeration, and the hygroscopic phase change link is designed to be carried out in the heat exchanger with high efficiency, and achieves mass transfer and heat transfer synchronization and a virtuous cycle. The present invention becomes an air-air heat exchanger with higher refrigeration efficiency.

Description

technical field [0001] The invention relates to an air-air heat exchanger for refrigeration using water and air as a mixed working medium, belonging to the technical field of refrigeration and air conditioning. Background technique [0002] At present, most of the working fluids used in air-conditioning refrigeration are Freon. Although this type of air-conditioning has high refrigeration efficiency, it has the problem of environmental pollution. Whether a new harmless substance can be used to replace Freon for refrigeration and have higher refrigeration efficiency is a difficult problem in the current refrigeration industry. [0003] In a general air-to-air heat exchanger, the low-temperature cold fluid flows through the cold side and exchanges heat with the heat exchanger fins on the cold side. The sheet performs heat exchange to lower its temperature and take away the cooling capacity to complete the entire heat exchange process. Generally speaking, the change in the co...
