DC Inverter Module Energy-saving Precision Cooling
Product Introductions
Conventional fixed-frequency precision air conditioners can only output a constant cooling capacity, cannot adjust to the actual thermal and humidity loads of the server room, and consume more energy.
The KMAL.S unit based on a modular design and using DC inverter technology, can dynamically match the actual thermal and humidity loads inside the server room in real-time, solving the energy consumption problem of data centers.
At the same time, the modules can be flexibly combined according to customer needs, making deployment more convenient and straightforward.
Applications
Data Centers
Data centers, communication server rooms, switching rooms
Large and Medium-sized Institutions
Government, medical, financial sectors
Special Environment Requirements
Archives, museums
The indoor fan of the unit drives air circulation within the room. During this process, indoor air flows through the air conditioning evaporator, transferring heat to the refrigerant. The refrigerant is transported via system piping to the outdoor unit, where the condenser dissipates the heat into the outdoor environment.
