AI Technical Summary
In existing technologies, heat pumps provide either too much or too little heat, resulting in a mismatch between heat demand and drying costs, and the heat pump load is not fully utilized.
A multi-temperature-controlled parallel drying heat pump system is adopted, which sets up multiple independent temperature-controlled zones. Each zone is equipped with two heat exchangers for dehumidification and heating. Through control methods, staggered drying is achieved to ensure that the temperature and humidity of each zone are independently controllable. By utilizing multiple zones to stagger their load phases, the heat pump load is optimized to match the actual demand.
This achieved a match between the heat pump heating load and actual demand, reduced drying costs, improved energy efficiency, and ensured precise control of the drying process in different areas.
