How to Calculate Outlet Air Temperature

The outlet air temperature can be calculated by the inlet air temperature, cooling water temperature and air flow capacity using the following procedure.

(Example) Inlet air temperature: 100°C, Cooling water temperature: 20°C, Cooling water flow: 17 L/min
Air flow capacity: 2,000 L/min (ANR), Air pressure: 0.7 MPa, Model: HAW22-14

Correction factor by cooling water temperature (pressure 0.7 MPa)

Correction factor by cooling water temperature (pressure 0.7 MPa)

1. Use an outlet air temperature of 37°C from the Outlet Air Temperature table. In this case, use correction line A.
2. Next, use the correction factor by cooling water temperature chart to obtain a correction factor of 1.3 at the water cooling temperature of 20°C on line A.
3. Divide 37°C (from step 1) by 1.3 (from step 2) to obtain the outlet air temperature.
Outlet air temperature = 37 ÷ 1.3 = 28.5°C

Precautions

Caution on Design

Warning

1. If the supply of coolant water is disrupted, the system will overheat, creating a dangerous situation. Therefore, make sure to take safety measures against water failure.
2. An excess or insufficient flow of coolant water can damage the heat exchanger tube. Therefore, design within the rated water flow range (refer to the standard specifications column).

Caution

1. Design the piping for coolant water and compressed air with a bore that is greater than the bore of the piping connections.
2. The quality of the coolant water to be used must exceed the water quality that has been specified by the Japan Refrigeration and Air Conditioning Industry Association. (Refer to the instruction manual.) Poor quality coolant water damages the heat exchanger and reduces performance, Therefore, inspect the water quality and replace the circulating water on a regular basis.
3. Use tap water or industrial water for coolant water. Never use sea water.

Mounting

Caution

1. Install the unit horizontal to the pipe line.
2. Make sure to correctly connect the compressed air inlet/outlet and the coolant water inlet/outlet.
3. Use union joints to connect the coolant water pipes so that they can be easily removed during maintenance.
4. Connect a drain pipe because a large amount of drainage is created when the compressed air is cooled.
The drain pipe must have a minimum pipe bore of 10 mm and a maximum length of 5 m (when installing an optional auto drain).

Mounting

Caution

1. Inspect the quality of the coolant water and replace the circulating water on a regular basis. If the coolant water is cooled in a cooling tower, it is susceptible to the adhesion of water scale, so replace the coolant water regularly.
2. If there is a likelihood that the coolant water will be frozen, drain the coolant water to prevent damage. Also, drain the coolant water when the equipment will not be used for a long period of time.
3. If the cooling performance decreases, clean the inside of the coolant water pipes. (Refer to the instruction manual for details on the cleaning method.)
