Air conditioning unit combining dehumidification with evaporative cooling and air handling method thereof

Abstract

The invention discloses an air conditioning unit combining dehumidification with evaporative cooling and an air handling method thereof. The air conditioning unit comprises a dehumidification cooling module, an equal-humidity cooling module, an evaporative refrigeration module, a solution regeneration module, a solution regeneration circulating pump, a solution cooling heat exchanger and a solution heating heat exchanger. The invention also aims to disclose an air handling method of the air conditioning unit combining dehumidification with evaporative cooling. The air conditioning unit provided by the invention be used for completely omitting a mechanical refrigerating system, thereby completely omitting completely the mechanical refrigeration energy consumption, and overcoming the problems that the refrigeration energy consumption is high, the indoor air quality is low, the noise is larger, the aeration sense is strong, the fan energy consumption is high and the like in the prior art; and the air conditioning unit has the characteristics of completely omitting the mechanical refrigerating energy consumption, adapting to wide high-temperature high-humidity regions, avoiding oversize noises and aeration sense, reducing the fan energy consumption, carrying out sterilizing and dedusting treatment on air, improving the energy utilization efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit combining dehumidification and evaporative refrigeration and an air treatment method thereof. Background technique [0002] The energy problem has increasingly become the most critical and urgent problem in today's economy and society. my country's building energy consumption accounts for about 1 / 3 of the total energy consumption, and the air conditioning energy consumption accounts for more than 50% of the total building energy consumption. Therefore, air conditioning energy saving is undoubtedly It has become an unavoidable problem in our country's economy and society. [0003] Traditional air conditioners mostly use the air treatment method of combined temperature and humidity control. In order to reduce the air temperature below the dew point to achieve dehumidification of fresh air, it has to use low-temperature cold water (7°C) lower than th...

AI Technical Summary

Problems solved by technology

However, the hot and dry areas in Northwest my country in summer are precisely the areas where water resources are seriously lacking, which seriously restricts the application of evaporative refrigeration technology. The temperature difference between the dry and wet bulbs of fresh air is very small, which makes the cooling effect of this kind of air cooler unsatisfactory, the comfort level is low, and it must be operated with a large air volume, which leads to loud noise and strong blowing feeling, and significantly increases the energy consumption of the fan At the same time, the indoor air humidity is too high due to the lack of dehumidification treatment of the fresh air, which further affects the comfort of the hot and humid environment, and often because the enthalpy value of the fresh air is higher than the enthalpy value of the design indoor air state point, the indoor heat load cannot be eliminated and the indoor heat load cannot be satisfied. Air condition requirements make it unable to meet the air-conditioning needs of the vast high-temperature and high-humidity areas in my country, but these vast areas are precisely the areas with developed economy, dense population, and the highest demand for air-conditioning in summer
