Expert Guide to Selection, Purchase, and Pricing of DamaTajhiz AHUs

In air handling units, fresh air and return air from the building are typically mixed and then passed through several layers of the AHU filtration system. Subsequently, during summer operation, the air is cooled by passing through fins and chilled water coils (or refrigerant coils), while in winter it is heated by passing through fins and hot water coils (or steam coils). Finally, the conditioned air is delivered by a supply fan—either forward-curved or backward-curved—with the required static pressure through the installed ductwork to various spaces within the building.

In full fresh AHUs, where 100% of the required air for the project in both summer and winter is supplied from the outdoor environment, the heat exchange surfaces as well as the cooling and heating capacities of the chilled and hot water coils are naturally much greater than those of conventional AHUs.

Moreover, if required, air humidification using water or steam can be carried out inside the AHU before the heating coil and before air distribution through the ducts. Air handling units generally consist of the following components: an airtight casing, a supply fan with adequate static pressure, a powerful electric motor with fixed or variable speed, filters, cooling and heating coils (with heat transfer surfaces suitable for project requirements), humidification nozzles, control equipment (for regulating cold and hot fluid flow or varying air volume and ultimately the supply air temperature), as well as intake, exhaust, and return air dampers.

DamaTajhiz AHUs, available in residential, industrial, and hygienic models, are manufactured fully in compliance with the latest international standards, with suitable or fast delivery, and are supplied to Iran, Afghanistan, Iraq, and other Middle Eastern countries.

DamaTajhiz Air Handling Unit Components

DamaTajhiz air handling units mainly consist of the following components:

• Sealed Body
• Ventilation Fans with Static Pressure
• Variable-Speed or Fixed-Speed Electric Motors
• Filters
• Cooling and Heating Coils (with appropriate heat transfer surface)
• Humidification Nozzles

• Inlet, outlet, return air damper
  
  

DamaTajhiz air handling units are designed and manufactured in domestic, industrial, and hygienic models according to the latest standards and are supplied globally, especially in the Middle East and West Asia, with fast delivery times.

Hygienic Air Handling Unit Advantages

According to the importance of air quality in certain places such as electronic industries, food industries, pharmaceutical industries, operating rooms, hospitals, etc.

Therefore, hygienic air handling units with special features such as the use of sound-damp cabins made of chrome-nickel alloy and equipped with an air recovery system equipped with HEPA filters, IPA filters, ULPA filters, UV lamps, etc., are used to provide clean or sterile air for any space.

What is the DX (Direct Expansion Coil) in an Air Handling Unit"

Air handling units with DX coils (direct expansion coils) use refrigerant gases such as R407, R410, and R22 directly in the air handling unit device rather than using cold water from a chiller.

The refrigerant gas in these devices (chiller or rooftop package) enters the coil of the air handling unit directly, instead of cold water from chillers (summer) or hot water from boilers (winter), and then enters the coil with a pump to reduce or increase the temperature of the air around the pipes by the refrigerant flowing in the inner tubes of the coil.

Factors to Consider Before Buying a DamaTajhiz Air Handling Unit

Since air handling units are one of the most important and practical types of air conditioning equipment in the building, they can have many varieties and complexities. Please check and declare the following key factors carefully before ordering or buying a DamaTajhiz AHU:

• The dimensions of the installation location of the air handling unit.
  
  
• Shape of the air handling unit, which can be either horizontal or vertical.
  
  
• The exact amount of cooling and heating capacity required by the project.
  
  
• The airflow direction of the air handling unit and how it will be connected to the ducts.
  
  
• The number and type of air filters in the air passing through the air handling unit.
  
  
• Type and pressure drop of the heat transfer fluid (hot water or steam) in the heating coils of the air handling unit.
  
  
• Either having 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.
  
  
• Type and pressure drop of the refrigerant fluid (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, the air pressure of the project site, and the outside temperature in summer and winter.
  
  
• The diameter and thickness of the coils, body sheet type, and frames of the air handling unit. 
  
  
• The amount of static pressure of the fan, which is the factor of air thrust inside the ducts and its transfer to the desired environment.
  
  

Extra:

Air handling units are designed and built based on the needs of the project and the customer's order, whether you need a single-zone or multi-zone AHU:

1. In single-zone AHUs, all areas of the building are ventilated with uniform temperature and humidity.
   
   
2. In multi-zone AHUs, it is possible to distribute air with different temperatures and humidity to different areas with the help of controllers and dampers.
