Damatajhiz Air Cooled Compression Chiller

Damatajhiz air-cooled compression chiller with screw and scroll compressor has been produced and supplied by Damatajhiz HVAC engineering group since 2004 in the Middle East; In the following, the technical specifications, capacity estimation, sales resume, and the best price of all types of apartment and industrial Damatajhiz air-cooled chillers are presented.

Selecting all types of DamaTajhiz air-cooled chiller

In general, the compressor is considered the beating heart and the main electromechanical equipment in all types of scroll and screw air-cooled chillers, and it has a very important effect on the efficiency of the device, performance coefficient, dimensions, useful life, and electricity consumption of air-cooled chillers. Therefore, all scroll air-cooled and screw DamaTajhiz air-cooled chillers, based on the type of order and project needs, are produced in screw, scroll and piston types and from well-known and reputable international brands such as Copeland, Bitzer and Danfoss (with a product ID code to track and ensure the authenticity of the product) and Also, the guarantee of Damatajhiz company with a suitable delivery time has been produced and supplied since 2004 in the Middle east.

The design basis and technical specifications are presented in the table of air-cooled chillers based on the temperature of cold water leaving the evaporator of 45°F (7°C) in the dry temperature of 104°F (40°C) in summer and to know the real capacity of the device in other weather conditions, you can contact our sales experts in the engineering department of Damatajhiz HVAC company.

Considering the variety and scope of technical issues related to air-cooled compression chillers in scroll and screw type, if you have a special order or more demand regarding other technical specifications of chillers, in addition to the product description and technical specifications, when purchasing the device, make sure these items to the sales experts of the air conditioning equipment department of Damatajhiz HVAC group.

Important points before buying DamaTajhiz air-cooled chiller

In the following, you can read important buying tips before purchasing the DamaTajhiz air-cooled chiller:

• It is possible to manufacture air-cooled chillers or other types of air-compression chillers in other capacities according to the order of the respected buyer.
• The compressors of Damatajhiz chillers are usually from reputable brands such as Copeland, Bitzer, etc.
• The declared capacities and specifications are related to Freon 22 gas, and to know the working capacity for other refrigerants such as R410, contact the engineering department of Damatajhiz HVAC company.
• When ordering the required air-cooled chiller, check its approximate dimensions to allow the chiller to pass through the entrance door and transfer it to the foundation of the installation site.
• The change in the technical specifications and equipment used in the DamaTajhiz compression air-cooled chillers can be done based on the customer's order (such as the installation of a plate converter for the evaporator) at different prices.
• The refrigerant in the air-cooled chiller circuit is higher in quantity, volume, and working pressure than in water-cooled chillers. In the air condenser, the chiller is cooled by a fan and forced air flow and usually directly enters the DX cooling coil of the air conditioner or the blue DX evaporator in the air chiller. Therefore, as you know, air-cooled chillers do not need a water-cooling tower.
• When choosing air-conditioned chillers, pay attention to the difference between the nominal capacity and the actual capacity of the chiller, especially about the design temperature outside the summer in the chiller operation area. Among the determining factors in the performance of the actual capacity of the air-conditioned compression chiller, we can point out the important issue of sufficient heat exchange levels in the condenser and evaporator of the chiller to choose the nominal capacity of the chiller (length, diameter, and the number of tubes used in the condenser and evaporator).
• Note that the price of air-cooled chillers (with air condenser, refrigerant gas, oil, etc.) is usually about 50% more expensive than water-cooled chillers with the same capacity. However, in places where cooling tower water supply is an issue Or in areas where the relative humidity is high in summer (such as hot and coastal cities), the use of air-cooled chillers is inevitable.

Determination of the capacity of the DamaTajhiz air-cooled chiller

In general, the facility experts calculate the air-cooled chiller capacity required for each project, which is based on the exact calculation of the total refrigeration load capacity, in addition to calculating parameters such as geographical conditions (Ambient Temperature), and summer design temperature, altitude above sea level, humidity relative air, type of use of the building (temperature inside the design), the type of materials used and execution of the building facade, the direction of the building about the angle of the sun, the number of floors and the surface of the building, the number of people and small and large electrical equipment inside the building and ..., pay attention to the volume of cold water required and sufficient reliability coefficients in chiller performance.
But if you want to use the possibility of calculating the fingertip (phase 1) of the air chiller required for residential and office buildings in climatic conditions like Tehran, you can approximately have a nominal capacity of 4 tons of refrigeration per 100 square meters of the building. Consider air-cooled chillers.
Also, before determining the final capacity and choosing the required air chiller for your project, please contact the experts of the air conditioning equipment sales department of Damatajhiz Company for the final control of calculations and correct estimates of the cooling load and the correct selection of the air conditioner chiller required for the project.
The use of air-conditioned chillers as the central core of the building's cooling system is generally used in areas with high relative humidity (RH) and so-called humid air.
In the air-cooled compression chiller, the liquid refrigerant in the chiller circuit, which is higher in terms of quantity, volume, and working pressure than water chillers, is cooled in the air condenser by the forced flow of the ventilation fan.
One of the advantages of air-cooled chillers is the possibility of operating and using the (FREE COLLING) system in them without the need to operate the chiller compressors when the outside air is cool, especially on cool nights.

Buying DamaTajhiz air-cooled chiller 

In the discussion of buying an air compression chiller (temperature-equipped air-conditioning compression chiller), before we talk about the price of all types of chillers and their complementary equipment such as fan coils, we need to have minimal information about points such as the climate and weather conditions of the installation site, We should have the amount of cold, the maximum cold water flow, the maximum required water pressure, etc.
