New concept purification and sterilization function

In accordance with the requirements of "Construction Standards for Clean Operation Department of Hospitals", "Technical Specifications for Construction of Clean Operation Departments of Hospitals" and "Air Conditioning Units for Clean Operating Rooms", it is equipped with a new concept of purification and sterilization functions. The design of the medical purification air-conditioning unit adopts comprehensive measures to fully control the bacteria, eliminating the possibility of breeding bacteria. The advanced sterilization device can carry out regular disinfection and sterilization very conveniently and effectively. It fully meets the environmental control of the clean operating room Require.

Inhibit dust accumulation and bacterial growth, effectively prevent secondary pollution of the unit

The flat and smooth inner wall design of the unit reduces air turbulence and kinetic energy loss, effectively inhibits the accumulation of dust and bacteria, and facilitates internal cleaning. No dead corners are left. It can also effectively prevent the corrosion of consumer agents and the erosion of wet air. Each functional section is located in the positive pressure section. Not only to ensure smooth drainage of condensate. No water, and can prevent secondary pollution.

Advanced all-round control technology with complete functions

Adopt advanced microcomputer control and luxurious colorful intelligent man-machine interface, professional electromechanical integration on-site supervision system, realize automatic control of constant temperature, VAV, VWV, IAO and energy saving; integrate intelligent area network, realize central monitoring, and integrate with BAS Each subsystem is connected through Ethernet to form a local area network. The control system of the unit can be equipped with a standard RS485 communication interface. Networking is very convenient.

Easy maintenance

It adopts a full frame structure, and all panels can be disassembled, which is convenient for installation and maintenance of the unit. At the same time, the unit is equipped with an inspection door for quick inspection and maintenance of internal components. All maintenance work can be carried out on one side of the unit without reserving space for maintenance on the other side.

Features of the unit

The handling air volume of the unit ranges from 2000m7h to 40000mVh, and there are 30 basic specifications, including direct expansion type and chilled water type.

The three-dimensional composite aluminum alloy frame structure, combined with the new composite sandwich double-layer insulation panel, enables the new generation of unit cabinets to have a true insulation bridge and zero-leakage design. It avoids energy loss caused by cold bridges and leakage and condensation on the outer wall of the unit, and blocks untreated air from penetrating into the system.

A new composite sandwich double-layer insulation panel, the inner panel is made of anti-corrosion and antibacterial plated cast steel plate or stainless steel plate. The outer panel is made of plastic-sprayed steel plate or color steel plate, and the inner and outer layers are filled with high-pressure foamed polyurethane thermal insulation material. The frame uses PVC board edge strips to cut off the cold bridge between the double-layer board and the aluminum frame, ensuring the heat insulation performance of the unit and Very low air leakage rate (≦0.5%), with better performance in terms of heat preservation, sound insulation, fire prevention, strength, service life and cleanliness.

The unit can be controlled by EDDC/PLC, which can realize various operating modes and accurately control indoor temperature and humidity.

The unit can be equipped with primary, medium and sub-high efficiency filters with special antibacterial treatment, and can be equipped with activated carbon filters with sterilization and deodorization functions.

The unit is equipped with PTC electric heating, which can be controlled in multiple levels, with low surface temperature, high heating efficiency, no static electricity, no open flame, safe and durable.

All functional components are located in the positive pressure section, which can ensure smooth drainage of condensed water, protect the evaporation coil from dust pollution, prevent the medium-efficiency filter from getting wet, and prevent secondary pollution.

The surface cooler is made of aluminum fins with hydrophilic film, which is not easy to accumulate dust and bacteria, and will not produce water.

All air filters are equipped with differential pressure warning devices to remind users to replace filters in time.

Use secondary drying dry steam humidifier or electrode humidifier to ensure that there is no water in the humidifier after shutdown, eliminate the possibility of humidifier bacterial growth, and prevent humidifier fever.

When the unit is shut down, the fresh air valve is closed at the same time, and the fan is delayed to stop to ensure that the coil is blown dry.

The unit is equipped with a manual forced start function to ensure that the unit can still be started when the control system fails.

The unit can be configured with a frequency conversion speed regulator/voltage regulator controller for the VAV control system to control the energy-saving operation of the fan and meet the requirements of the air conditioning system.

The outdoor condensing fan of the direct expansion unit can be equipped with a condensing fan speed controller according to customer needs to achieve the purpose of energy saving.
