Combined Direct-Expansion Type Purified Air Handling Unit

HonMing HMZK-D series direct expansion combined air conditioning unit is a high-tech product combining our company’ s latest air source compression and condensation technology and air treatment technology.

Covering single cooling type, heat pump type, purification type, constant temperature and humidity type, fresh air type and other series of products. The air treatment part can also be further designed according to the actual process requirements. Fully meet the special air treatment needs of all walks of life.

It has the advantages of self-contained cold source, customized air treatment, and control integration. The simplified system structure can realize flexible distributed applications and save engineering construction and equipment operation costs. It is a classic that embodies the concept of simple and efficient design.

Especially suitable for application fields with special needs such as medical treatment, hygiene, biological pharmaceutical, microelectronics, automobile manufacturing, experimental scientific research, food processing, schools, etc.

• Modular design

Air treatment part adopts modular design, each mold 100 mm, can flexibly design the height and width of the unit according to the installation site conditions, the installation is flexible, the unit can leave the factory as a whole machine, or can be assembled on site according to the need.

• Unique Broken Cold Bridge Aluminum Alloy Frame

High quality T6 aluminum alloy extrusion molding, excellent strength, beautiful appearance

• Double layer panel with excellent thermal insulation

Adopt 30-50 mm thickened double panel;

The inner/outer plate can be made of high quality color steel plate, high quality galvanized steel plate or stainless steel plate, or magnesium-coated aluminum zinc plate;

The intermediate rigid polyurethane environmental protection material overall foaming molding, has the best performance in heat preservation, sound insulation, fire prevention, strength, service life, cleanliness and so on.

• High quality components with high efficiency and low noise.

The outdoor AC unit of direct expansion combined air conditioning unit adopts brand-name completely closed vortex compressor with high efficiency, low noise and strong hydraulic resistance. The indoor unit adopts high quality double inlet centrifugal fan (AMCA certified fan selection) or no volute fan (optional) or EC fan (optional). Fan impeller and belt are tested and corrected by dynamic and static balance before leaving the factory, and equipped with shockproof measures, Low vibration, quieter operation, and longer life.

• Advanced control, reliable operation

Using single chip microcomputer or PLC control system, the operation panel can choose the text hand operator, or the LCD touch screen, controller has built-in fuzzy control or PID control, friendly man-machine interface, easy to operate, high reliability. The main electrical components adopt Siemens and other international famous brands, with low failure rate and long life, and can provide RS485 communication interface to realize remote monitoring.

• Excellent quality heat exchanger

The optimized and improved coil gap and the copper pipe supporting aluminum fin structure made of precision mechanical expansion pipe have high heat exchange efficiency and large heat exchange coefficient, ensuring excellent heat transfer performance. Aluminum fins are specially treated, which improve the corrosion resistance of the fins and greatly improve the durability of the heat ex-changer.

• Excellent air conditioning internal pipe structure

Using pipeline simulation design technology, perfect stress data analysis to prevent leakage. In the process of air conditioning transportation, it can effectively avoid the resonance of pipeline vibration and transportation vibration, reduce the fatigue damage of pipeline during transportation, increase the noise absorption ability of pipeline, and reduce the noise of air conditioning operation.

• Humanized design

Adopt full frame structure. All panels are removable to facilitate the installation and maintenance of the unit and equipped with maintenance doors for rapid detection and maintenance of internal components . All maintenance work can be carried out in the single side direction without reservation of space for maintenance on the other side, and the sharp corners of all unit components are passivized.

• International famous brand filters are selected

Multiple filter levels are optional. Reasonable configuration of filter grade can ensure that each level of filter is in the best working state. Filter and electronic purification filter can be selected.

• Energy saving and high efficiency

With its own cold and heat sources, it integrates the functions of air handling and automatic control. It has the advantages of less investment, simple system, less intermediate heat exchange links and high efficiency;

• Save space

The air cooling design is adopted, which does not need special central air conditioning main unit room, and saves precious space resources;

• Simple maintenance

The maintenance of air conditioning system is simple. Each system can be maintained independently without affecting the normal operation of other systems;

• Low initial investment

The indoor and outdoor machines are directly connected by copper pipes, without cooling tower, cooling water pump, frozen water pump and connecting pipe. The control is simple, and the project can be constructed in batches, and the overall project cost is low;

• Easy to install

Directly plug in the power cord to use.
