A GUIDE TO PURCHASING THE DAMATAJHIZ AIR HANDLING UNIT

In general, fresh air and return air from the building flow through the multi-layer filtration system of the air handling unit, and in the summer, the air is cooled by passing through the fins and coils of cold water (or refrigerant). In the winter, hot water (or steam) travels through fins and coils, heating the air that exits the air handling unit. Finally, this air is directed (forward or backward) by the ventilation fan from within the installed channels to various building areas. Additionally, before the cooling or heating coil and air distribution in the channels, the air is humidified by water or steam inside the air handling unit as needed. Most air handling devices comprise a body, fan, electric motor, filter, cooling, heating coils, humidifier sprayers, control equipment, dampers for incoming and output air, and return air.

WHAT IS A DX (DIRECT EXPANSION) COIL AIR HANDLING UNIT?

Air handling systems with DX coils or direct expansion use air chiller refrigerant gas (R407, R410, R22) directly in the air handling unit rather than using the chiller's cold water flow in its cooling coil to cool the environment. The refrigerant gas in the device (chiller-rooftop package) enters the coil of the air handling unit directly, as opposed to water being heated in devices like cold chillers (summer) or boilers (winter) and then entering the coil with a pump to reduce or increase the temperature of the air around the pipes (which is blown by the fan) by the refrigerant flowing in the inner tubes of the coil.

HYGIENIC AIR HANDLING UNIT

According to the importance of air quality in certain places such as electronic industries, food industries, pharmaceutical industries, operating rooms, hospitals, and so on, hygienic (sanitary) air-generating devices with special features such as the use of sound-damp cabins made of chrome-nickel alloy and equipped with an air recovery system including (HEPA filter, IPA filter, ULPA filter, UV lamp, and so on) are used to provide clean or sterile air.

TIPS TO ORDERING THE DAMATAJHIZ AIR HANDLING UNIT

Since the air handling unit is one of the most important and practical types of equipment for air conditioning in the building, it can have a lot of variety and complexity. Please check and declare the following items carefully before placing a purchase order:

• Type and horizontal or vertical air handling unit
• The exact amount of cooling capacity and heating capacity required by the project
• The face of the air handling unit (how to connect the channel to the device)
• The number and type of air filters in the air passing through the air handling unit
• Determination of the type and pressure drop of the heat transfer fluid (hot water or steam) in the heating coil
• Having a humidifier system or not having a humidifier system in the air handling unit
• The number of rows, diameter, material, and thermal surface of the cooling and heating coils of the air handling unit
• The number of heat exchange fins in the coil per square inch of the cooling and heating coil
• Required aeration volume (m3/hr - CFM) and return air volume percentage
• Determining the type and pressure drop of the refrigerant fluid (chiller cold water or refrigerant gas) in the cooling coil
• The static pressure of the centrifugal fan of the aeration device to overcome the pressure drop of the longest path of the aeration channel (backward and forward)
• The height above sea level and the air pressure of the project site, and the outside design temperature in summer and winter
