Variable-section inclined channel punched thermal mass exchanger

Abstract

The invention discloses a variable-section inclined channel punched thermal mass exchanger. The variable-section inclined channel punched thermal mass exchanger comprises an inclined channel punched thermal mass exchanger shell, a punched flat plate, a water absorption material layer, ventilating pipes, a water distribution pipe and a water collection pipe. Small holes are formed in the flat plate, and the ventilating pipes are inserted into the small holes. The thin porous water absorption material layer covers the top of the flat plate, and the water distribution pipe and the water collection pipe are arranged at the two ends of the flat plate correspondingly. The flat plate is arranged in a straight channel shell square pipe in an inclined mode, and a straight channel shell is divided into an upper inclined channel and a lower inclined channel. The water distribution pipe comprises a water inlet and a water outlet, and the water collection pipe comprises a water inlet and a water outlet. A drip hole is formed in the lower portion of the side face of the water distribution pipe, and a water inlet hole is formed in the upper portion of the side face of the water collection pipe. The variable-section inclined channel punched thermal mass exchanger has the beneficial effects that the structure is simple, the airflow organization is reasonable, the flow resistance is low, water management is easy, the dry air at the dew point temperature can be obtained, and the variable-section inclined channel punched thermal mass exchanger and other parts are easily assembled to form a novel energy-saving air conditioner through an external air header.

Description

technical field [0001] The invention relates to the technical field of evaporative refrigeration, in particular to a perforated heat-mass exchanger with variable cross-section oblique channels. Background technique [0002] my country is facing very severe energy and environmental challenges. In terms of energy consumption, the total energy consumption of buildings is about 1 billion tons of standard coal, accounting for about 30% of the country's total energy consumption; and the total carbon emissions of buildings are 1.96 billion tons, accounting for about 10% of the country's energy carbon emissions. 19.0%, of which compression evaporative refrigeration and air conditioning contributed more than 50% of building energy consumption and carbon emissions. At present, the energy efficiency ratio (EER) of compression evaporative refrigeration air conditioners is close to 8, which has reached a very high level, and the room for further improvement is very limited. It is very ...

Problems solved by technology

Indirect evaporative cooling solves the problem of increased moisture content in direct evaporative cooling, but the heat transfer efficiency is poor, and the temperature can only drop to the wet bulb temperature

So far, no matter the technology and equipment of direct evaporative cooling or indirect evaporative cooling, mainly heat and mass exchangers, cannot reduce the air to a lower dew point temperature. Therefore, the obtained cold air is difficult to be used as air supply for comfort air conditioners
