Rooftop packaged unit features :
High quality electronic expansion valve
The high-precision electronic expansion valve / Emerson thermal expansion valve throttles, dynamically controls the refrigerant superheat at the outlet of the evaporator, quickly responds to the operating conditions of the unit, and takes into account the regulation accuracy and reliability. It has the function of opening self inspection to ensure safety and reliability during operation.
Internal thread fin heat exchanger
The finned heat exchanger adopts high-efficiency internal screw tube, which makes the refrigerant form a liquid film on the inner wall of the pipeline. The special heat exchange surface designed for different heat transfer mechanisms and fluid media greatly improves the heat exchange effect, and then improves the capacity and energy efficiency of the unit; High quality hydrophilic aluminum foil and unique hydrophilic characteristics prevent condensate from forming a water bridge and ensure smooth heat dissipation and heat transfer.
Intelligent defrosting Technology
Through the comprehensive judgment of system parameters and optimizing the entry time of defrosting cycle, we can effectively judge the defrosting demand, so as to avoid unnecessary heat loss and improve the stability of air conditioning heating, with better heating performance.
Super protection function
Advanced microcomputer control system with complete safety protection functions and powerful fault self diagnosis function.
PLC control and microprocesser control available
