The total heat exchanger of the fresh air ventilation fan in underground parking lots is a key equipment used to improve the air quality of underground parking lots. It plays an important role in improving the air quality of underground parking lots, ensuring the health of personnel, and saving energy.
working principle
Underground parking lot fresh air centrifugal duct fans and total heat exchangers are usually used in combination to achieve efficient air exchange and temperature control.
The fresh air system introduces fresh outdoor air into the underground parking lot through pipelines, while also expelling polluted indoor air. The total heat exchanger exchanges heat between the fresh air and the exhaust air, recovers the heat from the exhaust air, and uses it to preheat or pre cool the fresh air, thereby improving energy utilization efficiency.
Functional Features
Efficient ventilation: It can quickly and effectively update the air in underground parking lots and maintain indoor air quality.
Energy saving and consumption reducing: The total heat exchanger reduces the energy consumption required for fresh air treatment and lowers operating costs by recovering heat from exhaust air.
High air volume design: Suitable for the large space and high air volume requirements of underground parking lots, ensuring effective air circulation.
Scénarios d'application
Underground parking lot: mainly used for ventilation and temperature control in multi-level underground parking lots.
Other enclosed spaces: also applicable to other enclosed spaces that require efficient ventilation and energy conservation, such as shopping malls, hotels, offices, etc.

Grain drying is an important step in ensuring safe storage and reducing losses, and the drying heat exchanger plays a crucial role in this process. The grain drying heat exchanger can quickly complete the grain drying process and improve production efficiency through an efficient heat transfer mechanism. Meanwhile, adopting waste heat recovery technology can significantly reduce energy consumption, lower production costs, and reduce carbon emissions, which contributes to environmental protection.
structure type
Tube and tube heat exchanger: Tube and tube heat exchangers, also known as shell and tube heat exchangers, have a simple structure, low manufacturing difficulty, and are easy to clean and maintain. During the process of grain drying, high-temperature flue gas generated by burning coal or other fuels is used as the heat medium.
Plate heat exchanger: Plate heat exchangers are widely used in grain drying due to their simple structure and low manufacturing cost.
working principle
Waste heat recovery: During the drying process of grain, a large amount of heat is generated. The waste heat recovery system improves energy efficiency by collecting this waste heat and transferring it to new dry air.
Preheating air: Some advanced grain drying systems utilize waste heat recovery technology to preheat fresh air, further improving drying efficiency.
Application scope
Plate heat exchangers are suitable for various sizes and types of grain drying equipment, whether it is corn drying towers in large grain storage and logistics centers or grain dryers in small farms.

working principle:
The waste heat recovery heat exchanger for painting and baking room exhaust gas is a device that exchanges energy between air and air through a heat-conducting plate, and uses the energy of exhaust air to pretreat fresh air, thereby achieving the purpose of energy recovery. The fresh air and exhaust air are completely separated by a heat-conducting plate to avoid cross contamination and ensure the cleanliness of the fresh air.
