Double Skin Fan Coil unit DDW

Features General Information DAIKIN DDW air handling units are designed to meet the needs of the terminal air conditioning market. DDW units are full featured handlers that are applicable for the central air-conditioning systems installed in hotels, supermarkets, hospitals and office buildings.

Without Frame Type DDW units are equipped with no frame structure patent of DAIKIN and prevent air leakage angle design,to ensure no cold bridge and low leakage rate.

Casing DDW Casing units is of double-skin panels and assembled with self supporting modular panel elements with an integrated base frame made of galvanized steel. assembled 25mm polyurethane foam offer ideal heat/sound insulation.

Filter Washable nylon primary air filter, removable and easy installation. Bag filter is optional.

Coil Selection All the computing results and the products built on these results have passed strict test. This ensures their safe, reliable and effcient operation.

Sirocco Fan High efficient and quiet titled multi-blade double-intake fans.

Motor V-belt driving,Class F,IP55 provide different amounts of air flow and ETP to meet different needs.

Installation Installing DDW Important Notice Installation and maintenance are to be performed only by technicians who are familiar with local rules and regulations, and experienced with this type of equipment. Make sure that the rated voltage of the power supply conforms to the voltage stated on the unit nameplate. Cut off all power supplies before mounting or maintaining the unit. Electric connections must conform to local laws and regulations. The voltage should fluctuate within the range of ± 10% of the rated voltage. The unit must be well earthed to prevent insulation failures. All the wires must be securely connected. The design of water pipes and ducts must conform to the Specifications of Heating, Ventilation and Air Conditioning (GBJ19-87). DDW Mounting Location Make sure it is convenient to connect wires and pipes in the selected mounting location. The minimum space reserved around DDW horizontal units is shown in Figure 1; DDW vertical units are shown in Figure 2. Unit: mm

Suspending Installation During the installation, please handle the unit or packing case with care, to avoid damage to any part. Before leaving the factory, the unit or its packing case already has forklift handling holes or hoisting holes. During the hoisting, the lifting poles should be strong enough to bear the unit weight. Please handle the DDW unit as shown in Figure 3.

Storage When a unit is placed protect it from dirt, rain, snow and even animals. Be sure not to damage the protective film on its surface.

Base Setup Adjust the base levelness The base, if not put on a level surface, may result in water leakage or break the dynamic balance of the fan due to poor drainage of condensing water or cause the bearing to fail or vibrate. The base height should match the U-shaped pipe blend. The drain pipe should be connected with the Ushaped water seal, as shown in Figure 4. Need suitable water seal when installing in order to condensation water drain smoothly.

Servicing And Maintenance Notices Responsibilities And Obligations This product comes to you with the DAIKIN service warranty. Only DAIKIN technicians or experienced technicians authorized by DAIKIN are allowed to install, test or maintain these products.

Using The Unit After installing the piping system, please first wash the pipes. To do so, be sure to shut off the valve connected to the unit, to prevent unwanted things in the pipes from entering the coils or blocking the loop. After the installation, please check there is anything unwanted inside the fan. Turn the blades by hand. If no unusual noise is heard, turn on the fan, to see if it is running properly. Before turning on the water flow, please open the exhaust valve to let the air out of the pipe till water flows out from the pipe. When the unit stops running, fill the coil with water or otherwise keep the pipe from erosion. When the environment temperature falls below 0°C in the winter, drain the pipe to prevent it from freezing. Clean the coils at regular intervals, to remove the dust from the coils. Clean the scale inside the coils every 2 or 3 years. If possible, use soft water to supply hot/cold water to the coils. Check the unit filter for dust regularly; if possible, please use a pressure difference detector. Once the resistance reaches the limit, wash or replace the filter media in time. After the unit runs for a week, please readjust the V-belt. Afterwards, check the belt every three months.

Servicing And Maintenance A sound maintenance schedule helps reduce operational failures. A dirty filter may worsen the performance and air flow of the unit. Thus, replace or wash the filter in time. Be sure to check the filter every month to see if it is clean enough. Wash the coils with compressed air or water. Brush the coil surface gently with a soft brush or use a vacuum cleaner to clean the dust. Do the following on a regular basis: Clean up the fans every 6 months, to keep them in good balance. Check and clean the water coils. Check the drain pipe in case dust or unwanted things block the pipes. Check if the bearing comes loose. If so, fix the fastening screw tightly to the bearing. Clean the dirt in the coils at regular intervals. Check that the side front of the fan V-belt is flush with the side front of the motor V-belt, to make sure the pulleys are placed on a flat plane. Usually, check using the four-point method (see Figure 5). Use V-belts of the same brand and model. Never mix old V-belts with new ones. Make sure that the V-belts match the pulley grooves. Use a tensiometer to check the V-belts, and tighten them properly (see Figure 6).

Possible causes

Solutions

Blower is mounted incorrectly

Contact the seller

Fan rotates in the opposite direction

Regulate the power phase sequence

Actual resistance in the duct exceeds set resistance.

Re-design the system

Duct is poorly sealed

Seal with glue

Fireproof valve is shut off

Shut on the fireproof valve

3. Filter

Too dirty or even blocked

Clean or replace filter

The fan is 4. Coil functioning but the air 5. Blocked air supply supply is insufficient 6. Fan air inlet is blocked

Too dirty or even blocked

Clean coil

1. Fan

2. Duct system

The air inlet and the air outlet are not properly isolated. Thus, Add air deflector the air runs directly to the air inlet through the separator Elbow at the return air inlet and fan outlet are too close to the Move the fan unit wallboard The fan outlet is blocked

Remove the obstructions

A length of straight tube is mounted at the fan outlet during 7. No collimator tube at fan testing. Without straight tube, the fan performance might the fan outlet be worsened. Thus, the fan may run faster to offset the resistance. (Check the fan speed) 8. There’re unwanted The fan outlet is blocked things inside fan There is an elbow at the fan outlet system

The fan is functioning 1. System but the air supply is too large 2. Duct

Mount collimator tube Remove the obstructions Re-design duct

Improper duct size

Remove the obstructions

The access door is open

Close the access door

The system is not well balanced and the actual resistance is lower than the set resistance

Re-design the system

No air valve or air valve blade

Mount wind valve or wind valve blower

Filter falls off

Re-mount the filter

Return duct leaks

Seal it with glue
