Double-runner fresh air treating unit combining total heat recovery runner and dehumidifying runner

Abstract

The invention belongs to the field of heating ventilation and air conditioning, and particularly relates to a double-runner fresh air treating unit combining a total heat recovery runner with a dehumidifying runner. The double-runner fresh air treating unit consists of a plurality of layers of channels, and can be used for dehumidifying and cooling fresh air. A solid adsorbent having moisture absorption performance is taken as a dehumidifying medium, and a honeycomb-shaped runner is taken as a carrier for performing total heat recovery and dehumidification on the fresh air. The runner has a large specific surface area, so that the size of the device can be reduced, and superior dehumidification and total heat recovery performance is realized; by using the total heat recovery runner, the cold and hot quantity input of active cold and heat sources can be reduced, so that the energy consumption in a fresh air treating process is lowered. By adopting the device, high-temperature cold source cooling and low-temperature heat source heating can be realized, so that efficient cold and heat source driving of solar energy, heat pump systems, high-temperature cold machine cold water and the like can be adopted. Therefore, an efficient fresh air dehumidifying and cooling process can be realized efficiently in summer by using the system.

Description

Technical field [0001] The invention belongs to the field of heating, ventilation and air conditioning, and particularly relates to a double-rotor fresh air processing unit combined with a total heat recovery runner and a dehumidification runner. Background technique [0002] In the process of building thermal and humid environment control, the introduction of fresh air can effectively remove indoor pollutants and improve indoor air quality. However, the increase in fresh air volume will also increase the energy consumption of the air conditioning system. Therefore, improving indoor air quality while reducing the energy consumption of fresh air treatment is an important issue for building energy conservation. Efficient dehumidification methods and the use of total heat recovery have significant effects in reducing the energy consumption of fresh air treatment. [0003] Commonly used condensation dehumidification methods have the disadvantages of higher energy consumption and bact...
