Nowadays, Fresh Air treatment and energy conservation are hot topics in the industry, more design and study on fresh air handling is on going, mainly deal with removal of moisture and pre-cool. The application of Heat Pipe should be a good choice on fresh air handling.
There are heat revovery type and dehumidificaiton type heat pipe, by using the characteristic of refreigerant, temperature difference of environment and unique design of tube  circuit, you can obtain energy from the air for pre-cooling or re-heating without energy input, specially ideal for fresh air treatment, achieving energy save as well as better air quality.
