How to find the causes and repair water chiller

How to find the causes and repair water chiller

In the process of operation and use of air conditioners in general and chillers in particular, there are many incidents that make users face with many difficulties. In this article we provide readers with the most basic knowledge to determine the causes, phenomena and remedies when air conditioning (chiller) is in trouble.To help you deal with problems during the machine operation and use, we would like to introduce some of the following common problems:

Some attentions of desicant air dryer (heatless type) maintenence

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, in fact there are many different problems  such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using  time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended  maintenance   in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operate safely Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen  longevity  of mạchine as well as compress
Piston maintenance and repair

Piston maintenance and repair

Piston compressors are widely used in industry (manufacturing factory), with high mobility, simplicity , easy repair, cheap price which are suitable for many objects. Therefore, Piston compressors are widely used in daily life such as: motorbike inflation, car drying , pumping car tires...

Wiring for remote operation of Handsome II air compressor

The compressor can be operated remotely with the LOCAL/REM selector switch on the meter panel. For the remote operation, the following wiring work is required. Before wiring, be sure to turn off the main power and make sure that no electric power is supplied to the compressor.

Location for installation of Hansome II air compressor

Tuesday - 30/07/2019 23:58

Location for installationis of  Hansome II air compressor very important to the compressor system. Proper place can avoid some bad affects from environment, improve the efficiency  as well as lengthen the life of the machine. Following are some cautions which must be highly considerable to ensure the durable operation. ​​​​​                       

        1.Places to be avoided of  Hansome II air compressor.

  • Avoid outdoor. This machine is designed for indoor use only. 
  • Avoid rain. Use or store in location where the machine is protected from rain. Exposure to rain may cause electrical leakage or rust, as the machine is equipped with electrical parts. 
  • Avoid places where the atmosphere contains a lot of dust such as inron powder and sand , or hamful gases such as chlorine, hydrogen sulfide, zinc oxide, and high concentration ozone. Such subtrates may cause damage to the compressor main body, poor insulation in electric components, deterioration of lubricants, or corrosion in parts. 
  •  Avoid places where the ambient temperature exceeds 40◦C (140ºF). It may cause serious accidents such as burning of the machine and fire. 
  •  Install the machine on a flat and level floor. Placing the machine on blocks may hinder the proper operation. 
  • Avoid places where excessive vibration is expected. 
  • The noise level may change depending on the building construction  and the installation site.

2. Environments to be avoided of  Hansome II air compressor

             Avoid environments where the units my suck in:
  • Mist of cutting fluids from machine tools
  • Exhaust/ smoke from boilers
  • Cracked gases of plastics
  • Vapor of waste water/liquids in food processing plants
  • Emission from vehicles including trucks
  • Any other harmful gases including NH3, SO4  and NOx.
                Caution 
  • Avoid installation in environments where the machine may suck in harmful gasses containing subtances listed above. Sucking  in such gases may cause clogging off the oil separator element, resulting in malfuntional shutdown. 
  • Ventilation to avoid sucking harmful gases/mist.
  • Provide a suction or exhaust fan or ventilation duct.
  • Do not install the compressor in the downstream of gas flow.

3.Installation of Hansome II air compressor space for safe operation.

  • Secure sufficient space away from the outlet above the inlet on both side faces the machine to ensure proper funtion.
  • Secure sufficient space away from the front and upper faces of the machine to ensure proper opening and closing of door, operation, and maintenace. 
4.Install the machine in an enclosed room.
  • Installation of a vetilating fan 
  • Be sure to provide a suction opening to take in fresh air and an exhaust opening to send out the rising air. Equip the exhaust opening with a fan.
  • When the ambient temperature exceed 40ºC (104ºF), the compressor may be shut down due to a high temperature alarm
  • Use the ventilating fan with the specifications equal or better than the following.
Type  HM37A HM37AD
Calorific volume  Mj/h 154 175
Ventialting capacity  Kcal/h 36800 41900
m³/min 430 500
       The above figures are in the case of ambient temperature rise by 5ºC (41ºF) and the static pressure of 0 Pa ( 0       mm H2O).
  • Installation of a ventilating duct.
  • Be sure to install a ventilating duct if a ventilating fan can not be installed. 
  • Do not fix the compressor directly to the duct with screw or others. 
  • Cover the exit of the duct with a metal net to prevent obstacles from entering the duct. Also take necessary measures to prevent rain water from coming in.

           Equip the duct exit with a ventilating fan if the pressure loss in the duct exceeds 50 Pa ( 5 mm H2O).
