Mine Exhaust Waste Heat Recovery Anti-Freezing System for a Coal Mine
In northern China, winter mine intake shaft heads freeze easily, threatening safety. Using the large amount of low-grade waste heat in mine exhaust to preheat fresh air can replace traditional boiler heating, achieving both energy saving and anti-freezing goals.
Indirect Evaporative Cooling Retrofit for a Data Center
Equipped a large data center with an indirect evaporative cooling system that uses outdoor dry air through a plate heat exchanger to cool the data center return air, reducing compressor cooling runtime and significantly lowering PUE.
Boiler Flue Gas White-Plume Elimination Retrofit for a Thermal Power Enterprise
For wet flue gas from boilers in steel, coking, chemical and thermal power industries, a BXB plate heat exchanger cools and condenses water out, then reheats before discharge, eliminating white plumes and reducing pollutant emissions.
Ventilation Heat Recovery System for a Modern Mushroom Cultivation Base
In modern greenhouses for mushrooms, flowers and other crops, heat recovery fresh-air units maintain temperature, humidity and CO2 concentration while recovering over 60% of exhaust heat, providing a stable growth environment.
Heat Pump Drying Exhaust Heat Recovery System for a Food Enterprise
For drying production lines of fruits, seafood, herbs and other products, a heat pump combined with a plate heat recovery unit recovers sensible and latent heat from drying exhaust, reducing compressor load and improving drying speed and product quality.
Fresh Air Heat Recovery Energy-Saving System for a Large Transportation Hub
In crowded public places such as airports and high-speed rail stations, fresh air energy consumption accounts for a high proportion of total HVAC load. This project uses fresh air ventilation equipment with heat recovery devices to transfer cooling or heating from exhaust air to the fresh air side for pre-cooling or pre-heating, effectively reducing the main HVAC load and improving indoor air quality.
Free Cooling Heat Exchange System for a Large Data Center
Installed 4 large detachable plate heat exchangers as free cooling heat exchangers for a data center, achieving 2,800 hours of annual free cooling operation, saving 3.2 million kWh per year, reducing PUE from 1.52 to 1.41.
Fresh Air Heat Recovery for a GMP Pharmaceutical Cleanroom
Integrated hygienic cross-flow plate heat recovery units into the fresh air handling system of a pharmaceutical cleanroom, achieving 72% heat recovery efficiency, saving 860,000 kWh electricity per year and reducing HVAC energy share by 35%.
Steam Condensate Waste Heat Recovery for a Large Food Enterprise
Used hygienic detachable plate heat exchangers to recover waste heat from 85C steam condensate to preheat boiler feedwater, saving 2.1 million Nm3 of natural gas per year, about 5.2 million RMB in cost, with only 0.8-year payback.
