China hopes to build a $5 billion particle collider within three years, ahead of Europe's proposed giant collider. The 100-kilometer-diameter Circular Positron-Positron Collider (CEPC) is designed to accurately measure the Higgs boson, the mysterious particle that gives everything its mass. This information could answer fundamental questions about how the universe evolved and why particles interact the way they do.

When the total heat exchanger operates in the summer cooling period, the new air is cooled from the exhaust air to reduce the temperature, while being dried by the exhaust air to reduce the humidity of the new air; when it operates in the winter, the new air is heated from the exhaust air to increase the temperature, while being humidified by the exhaust air. Fresh air ventilator is a kind of fresh outdoor gas sent into the room after filtering, purifying and heat exchange treatment, and at the same time, the indoor polluted harmful gas is filtered and purified.
