Maximum Height Difference Between Indoor and outdoor units (H)
Under 50m (Under 40m if the outdoor unit is installed below the indoor unit. Under 15m if the outdoor temperature is under 10˚C.)
■ Selecting Refrigerant Pipes
Gas pipe: Liquid pipe:
■ Adding the Refrigerant The outdoor unit is shipped with 8.5 kg of refrigerant. It does not include enough refrigerant for extra piping system. Use additional refrigerant for each refrigerant piping system (2 refrigerant circuits). Record the length of the pipe and the amount of the added refrigerant on the outdoor unit for services in the future. ■ Calculating the amount of refrigerant to be added
ø 28.58 ✕ 2 ø 12.7 ✕ 2
Size of the liquid pipe Total length of the pipe with a diameter of ø 12.7 ✕ 0.12
+ 2.0kg
(m) ✕ 0.12 (kg/m)
(i.e.) When using a 120m pipe with a diameter of ø 12.7 120m ✕ 0.12kg/m + 2.0kg = 16.4 kg
· The amount of refrigerant needed for additional piping depends on the diameter and the length of the added liquid pipes. · Calculate the amount to be added as shown on the right, and add the refrigerant in that amount. · Round up the figure under 0.1kg. (e.g. 11.06kg would be 11.1kg).
Caution Charge Liquid Refrigerant Filling the equipment with gas refrigerant will result in a power loss due to transformation of refrigerant in the tank.

✻1 20HP indoor unit is shipped with B1 and B2 terminals of TB21 and A1 and A2 terminals of TB23 short-circuited respectively. When connecting wire to those terminals, do not eliminate this feature. If it is eliminated, the units in one of the 2 refrigerant circuits may not operate. ✻2 Do not bundle with high-voltage (AC220-240V) wire, since noise interference from such wire may cause the unit to malfunction. ✻3 Do not bundle with minute-voltage (DC30V or below) wire, since noise interference from such wire may cause the unit to malfunction.
Caution 1) Wiring should be covered by insulation tube with supplementary insulation. 2) Use relays or switches with IEC or equivalent standard. 3) The electric strength between accessible parts and control circuit should have 2750V or more. 4) TB21 is a terminal specifically for No-voltage contact point input. Do not apply voltage to TB21, since it must result in malfunction of indoor unit controller board. 5) TB23 is specifically for contact point input with voltage. Check the polarity before connecting to avoid damage to the unit. 6) Keep the wires on the input side and on the output side away from each other when using AC220240V as a power source for displays. 7) Keep the length of the extension part of external signal line under 100m. 8) 20HP is shipped with B1 and B2 terminals of TB21 and A1 and A2 terminals of TB23 short-circuited respectively. Do not eliminate this feature. If it is eliminated, the units in one of the two refrigerant circuits may not operate.

9. Air Conditioning the Computer Room 9-1 Main Features of the Floor-Duct Air Conditioners This system is installed by building a floor over an existing floor and using the space between these two floors as an air-conditioning duct. This system has the following characteristics: 1 The temperature and humidity can efficiently and reliably be controlled, since the air-conditioned air is sent directly to the machine. 2 It provides a comfortable environment for the operator, since the air can be conditioned to best suit the needs of the operator and machines. 3 It is favorable in terms of appearance because the air-conditioning duct is out of sight. 4 The location of the duct is irrelevant when considering adding new machines or rearranging the existing machines, since the entire floor serves as the air duct.
Ceiling
Free-access top floor
Computer
Filter
Caution (1) Unlike plenum ventilation and overhead-duct type conditioners, since the conditioned air is not mixed with the air in the room, the air that comes out of the unit has to meet the predetermined conditions (constant temperature/constant humidity) at the time the air exits the unit. Close attention must be paid to the auto-controlling system. (2) Dust in the duct space (between the free-access top floor and the existing floor) must be thoroughly removed before installing the unit. (3) Since the existing floor is cooled by the unit, it may produce dews on the ceiling of the room down below.
9-2 Major Characteristics of Computer Room Air Conditioners (Constant Temperature · Constant Humidity) A computer-room air conditioner is a device that is used to maintain certain temperature and humidity in the room. Especially, floor-duct conditioners must be able to provide air that meets predetermined requirements. In this unit, the compressor works year around. To respond to the change in temperature, the capacity control compressor regulates the temperature. Since this unit does not ship with a humidifier, humidity is controlled with the use of a humidifier installed in the room.

9-4 Conditions for the Installation of Computer-Room Air Conditioners (1) Outdoor Temperature and Humidity Generally the values set for general air conditioners are used, although the value higher than the maximum outdoor temperature and humidity may be set for devices like computer-room air conditioners that must keep the air temperature and humidity under predetermined levels.
(2) Indoor Temperature and Humidity There is a wide range of conditions set by different computer manufacturers, and the conditions need to be set in consultation with the manufacturers. The most basic conditions include keeping dew condensation and static electricity from forming. It is also necessary to keep the room free of dust to ensure a smooth operation of the computer.
(3) Matching the Volume of Air Flow It is possible to use the fan on the computer to cool the room. This controlling method requires a certain volume of cold air in proportion to the amount of heat produced by the device. The inlet panel is located at the bottom of the unit, and the exhaust pipe is located either on the ceiling, front and back, or on the side. Air intake
Air conditioner
Computer Fan Free-access floor Air discharge
(4) Considering a Back-up Air Conditioning System When the system is not allowed to stop at all, a back-up system is necessary. There are several different options for a back-up as the following: 1 Installing two sets of air conditioning systems necessary for the computer. 2 Utilizing regular office air conditioners (for people) 3 Using one of the units as a back-up 1 is used infrequently due to high costs involved. 2 involves many technical problems such as the difference between preset conditions for computer rooms and office rooms. In general, 3 is a preferred method. If 3 is chosen, the unit method (package method) is more economical than the central method.
36
9-5 Setting the Air conditioners (1) Air-Conditioning Load 1 Once the floor plan is made and the conditions for the air-conditioning system are set, air conditioning capacity has to be determined by calculating the load. 2 Unlike the outdoor air, computer load remains constant throughout the year. However, it is possible that there are considerable fluctuations within a day. This is due to the fact that, depending on the time of the day, there are changes in the number of computers that are turned on and that the different computer systems are in operation. 3 If there is a plan to expand the current computer system in the future, it is important to include the load for the units to be added in the future when calculating the thermal load because it is practically impossible to keep the computers off for days on end during the installation of the new units. 4 The following items need to be checked before calculating the unit capacity: · Floor area of the computer room (m2) · Total quantity of heat generated by computers

(2) Notes ●The above chart shows a maintenance schedule for a unit that is used under the following conditions: A. Less than 6 times per hour of compressor stoppage B. The unit stays on 24 hours a day. ●Shortening the inspection cycle may need to be considered when the following conditions apply: ➀ When used in high temperature/high humidity area or when used in a place where the temperature and/or humidity fluctuate greatly ➁ When plugged into an unstable power source (sudden change in voltage, frequency, wave distortions) (Do not exceed the maximum capacity.) ➂ When the unit is installed in a place where it receives vibrations or major impacts. ➃ When used in a place with poor air quality (containing dust particles, salt, poisonous gas such as sulfuric acid gas and sulfuric hydrogen gas, oil mist). ●Even when the above maintenance schedule is followed, there could be unexpected problems that cannot be predicted. ●Holding of Parts We will hold parts for the units for at least 9 years after the termination of the production of the unit, following the standards set by the ministry of economics and industries.
