Air conditioning units for clean operating rooms

I. Model Description

The inner surface corners of the unit are designed with arc transitions for easy cleaning, and gaps are sealed with silicone-free sealant; the cooling coil section is located in the positive pressure section, without a water baffle, and the dry drain pan ensures smooth drainage, preventing water accumulation: equipped with ultraviolet
germicidal lamps; the drain pan is made of antibacterial material, providing continuous sterilization with an efficiency of over 99.99%; the inner wall panels of the casing can be made of antibacterial material for better antimicrobial effect.

For units with strict temperature and humidity requirements, electric heaters can adopt multi-stage proportional distribution or 1:2:4 differential distribution to meet the fine-tuning accuracy of temperature rise. Humidifiers can be selected from dry steam humidifiers, electrode humidifiers, or electric heating humidifiers. Through advanced automatic control, high-precision sensor configuration, and strictly controlled cold and heat sources, AAHM-H2 series units can achieve high-precision control of temperature and humidity (up to ±0.5℃ for temperature and ±2% for humidity).
This series of products offers primary, medium, and high-efficiency three-stage filters, with filter grades up to H13. It also provides fiber activated carbon composite filtration, TiO2 sterilizers, UV sterilizers, etc., effectively removing dust and sterilizing to ensure fresh and healthy indoor air with multiple filtration devices. The AAHM-H2 series units, powered by energy sources, can achieve high-precision control of temperature and humidity (up to ±0.5℃ for temperature and ±2% for humidity).

All structural forms of air conditioning units, except for ceiling-mounted units, should be installed on a level foundation. Sufficient space should be left around the unit, especially on the side of the unit's piping and the access doors for the fan and motor, to facilitate daily inspection and regular maintenance of the unit. The condensate drain outlet must first be connected to a "U"-shaped drain pipe before connecting to the external pipe. When connecting the inlet and outlet pipes of the coil, force should be balanced, avoiding excessive force to prevent damage to the coil. The motor of the air conditioning unit should be connected to a power supply with overload protection and have grounding protection. A flexible connection should be used between the air conditioning unit and the external duct to avoid vibration transmission. For direct expansion units, the connecting pipes between the indoor and outdoor units should be as short as possible, and reduce height differences and elbows.
quantity. Outdoor units require sufficient space for inspection and heat dissipation.

VI. Unit Usage

Before each unit operation, all valves in its water and air ducts should be checked and ensured to be in normal operating condition.
Connections, operation, and transmission of moving parts such as fans and motors should be regularly checked and adjusted promptly. Primary filters should be cleaned with clean water or a cleaning agent depending on the degree of dirt, and the frequency of cleaning depends on the operating environment. Medium filters should be cleaned or replaced when their resistance rises to twice the initial resistance. When the unit is not operating in winter, the water in the coils should be drained; if the unit continues to operate in winter, for a short shutdown, water must be kept flowing continuously within the coils, and the fresh air damper should be closed to prevent coil freezing. For long-term shutdown, the water in the coils needs to be drained. Cold and hot water should be clean softened water. Every two years of operation, scale inside the coils should be chemically removed, and fins should be cleaned with compressed air or water.
Surface dirt. The steam valve must be closed before the fan stops. The electric heater must be turned off 5 minutes before the fan stops after the fan is turned on.
