Combined Air Conditioner

• Self-owned foam molding equipment: Using self-owned high-quality foam molding equipment, the unit box panels are independently foam molded, ensuring the quality control of the panels. High-quality boxes significantly reduce heat loss
• High-Strength Enclosure: The box panels are integrally foam molded, with an aluminum-plastic composite frame around the perimeter, multiple sealing joints, steel plate interior lining, high-strength connecting cover plate, right-angle support fixing, bolted joint sealing, ensuring high mechanical strength of the enclosure.
• Complete Cold Bridge Disconnection: The profiles adopt an aluminum-plastic composite structure, with the inner and outer panels completely separated by materials such as PVC and EVA. The interior is filled with high-pressure foamed polyurethane insulation material, effectively eliminating cold bridges in the box and reducing heat loss.
• Highly Sealed Inspection Door: The inspection door leaf is integrally foamed, and seamless adhesive technology, combined with a double-edged sealed door frame, ensures no deformation or leakage under a pressure of 3000Pa, eliminating any loss of cold.
• Neat Interior of the Enclosure: The interior of the enclosure is seamlessly joined with a smooth surface, free of dust corners. The water tray adopts a three-dimensional dam-like structure to ensure complete drainage of condensate during operation, preventing bacterial growth.

Partial Product Types of Combined Air Conditioner

Efficient Purification Combined Air Conditioner

Fluidized Bed Air Treatment Combined Air Conditioner

EC Digitalized Energy-Saving Combination Air Conditioner

Efficient Purification And Sterilization Combination Air Conditioner

Working principle:

• Both supply fan and exhaust fan are built inside to bring in fresh air and exhaust out the stale indoor air as well, thus to keep indoor space in natural comfort.
• Built-in heat exchanger (rotary heat exchanger or plate heat exchanger) transfers energy contained in the outgoing indoor air to the coming fresh air, thus fresh air is precooled or preheated.
• Various functional sections such as filter section, cooling/heating section, humidifying section etc. can be combined together to meet different air treatment requirements.

Main Combination:

Combination mode 1:Wheel + Coarse filter (medium filter) + Cooling coil (heating coil+ Humidification + Fan)

Main Combination:

Air handling units with heat recovery core

Air handling units with heat recovery rotary wheel

Fan Section

We offer different types of fans such as direct driven centrifugal fan, belt driven DIDW forward centrifugal fan, and belt driven DIDW backward centrifugal fan etc.

Direction of Fan Output

Air filter

In order to ensure heat exchanging efficiency and cleanness, combination of G3 coarse filter and F5 medium filter is selected as standard configuration in HJK AHU.

Heat Exchangers

Crossflow total heat exchanger, cross-flow plate heat exchanger, or rotary heat exchanger to meet different demands.
