Application scenarios and effects of heat recovery fresh air system

1. Application scenarios

‌Commercial buildings‌

‌Typical places‌: Large shopping malls, office buildings, airports, etc., using rotary heat recovery units to handle large air volume needs, combined with 

frequency conversion technology to reduce air conditioning energy consumption

‌Case‌: A complex in Changsha saved 600,000 yuan in electricity and 800,000 yuan in gas fees annually through the "cooling tower frequency conversion 

+ heat recovery" transformation, with a payback period of only 2.5 years

‌

Medical and laboratory‌

‌Demand‌: Plate heat exchangers are suitable for high-cleanliness places such as hospitals and laboratories due to their strong airtightness and no 

cross-contamination risks

‌

Industrial plants‌

‌Functional adaptation‌: For industrial scenarios such as printing and textiles, the system combines antifreeze design and large air volume processing 

capabilities to recover waste heat for heating or process heating

‌High-end residential buildings‌

‌Technology selection‌: Small full heat exchangers achieve indoor constant temperature and humidity, with multi-layer filtration System (such as PM2.5 filtration) 

improves living air quality

II. Actual effect

‌Energy saving efficiency‌

The waste heat recovery rate can reach 60%-80%, and the air conditioning load is reduced by more than 35%

After combining with frequency conversion technology, the overall energy efficiency is improved by 20%-30%

‌Economic benefits‌

The investment recovery period of commercial building renovation projects can be shortened to within 2.5 years

In industrial scenarios, recycling heat for process pretreatment can reduce fuel costs by 30%-40%

‌Air quality optimization‌

The filtration system can remove pollutants such as PM2.5 and bacteria, and the fresh air cleanliness is more than 95%

The humidity control function stabilizes the indoor relative humidity in the comfortable range of 40%-60%

‌Multi-function expansion‌

Some systems can be linked to hot water supply (such as recycling waste heat to produce domestic hot water) and auxiliary heating to achieve "one machine for multiple uses"
