Introduction

Different from the traditional commercial and household air conditioner, outdoor cabinet air conditioner is a full automation temperature control product, it used intelligent controller to control the whole system of the air conditioner and widely deployed in telecommunication outdoor base stations, power station outdoor cabinet, outdoor LED screen, where require the temperature level below than 35℃ situation.

Feature

• This series of products can be widely used for outdoor communication cabinets, battery cabinets, electric cabinets and industry control cabinets etc.
• The protective level of internal and external circulation is IP55, which can protect cabinet to avoid moisture, dust, water. The air conditioner can also be indoor or outdoor installed.
• R134a system.
• R134a system fits working conditions of high/low temperature 55℃/-5℃.
• Digital temperature controller and high precision of temperature control.

Note:

1. Above model are powered by AC power, if you need DC powered or other parameter, please contact the representative or other distributors from whom you purchased your product.
2. Heating function is optional, and the heater power is manufacturer’s default (heater power capacity also can be customized), please consult the representative or other distributors from whom you purchased your product.

Air Conditioner Parameter Selection Method

Formula:
Qt = (Qi + Qr) ×1.2
Qt: Heat released by the cabinet (W)
Qi: Heat released by the inner cabinet (W)
Qr: Heat spreads from outside to the inside of cabinet (W)
Qi: Heat released by the inside of the cabinet (W)

The calculation of the heat released by the components in the cabinet is based on the following (related to the components installation)：

1. Heating of variable-frequency drive, transformer, drive and servo amplifier etc.If the equipment is rated power 1K, it will generate approx. 30~50W heat (depending on the load and divided by fan pump load and mechanical load);
2. PLC is about 35~50W heating(group as a unit), heat of industrial personal computer is controlled by its size. All calculated of 300W/ unit;
3. Heat of contact components: rated power 1KW is about 5~20W heat, can be ignored compared with large power components;
4. Heat of common server is about 280-500W. Heat of UPS is 20% of its power; When the variable-frequency drive is working with load, its loss (transformed into heating) is about 3%~5% of system rated power, which can be calculated. When the variable-frequency drive is of 1KW, the loss maybe 30W to 50W;
5. Heat of SCR: 2W/A,1KW DC Drive is about 7W~10W.

Qr =k×A×ΔT
k—Heat transfer coefficient
k=5.5W/ m2 Steel cabinet
k=12.0W/ m2 Aluminum-magnesium alloy enclosure
k=0.2W/ m2 Plastic material cabinet
A —Surface area of the cabinet（unit—m2）
ΔT=T1 – T2 （unit—℃）
T1—maximum temperature of outside cabinet
T2—controlled temperature of inside cabinet
The air-con. outdoor cabinet cooling requirement:
Steel cabinet dimension(L×H×D)：1500×2000×800 mm
Heat of the inside element is 1000W,controlled temperature inside cabinet is 28 ℃, outside temperature is 35 ℃
The calculation process of air conditioner parameter :
Surface area of the cabinet—A=1.5×2×2+0.8×2×2+ 1.5×0.8=10.4 m2.
Heat rumored from out to inside of cabinet—Qr = k ×A×Δ T = 5.5×10.4×(35-28) =400.4 W
Total heat produced by the cabinet—Qt =( Qi + Qr) ×1.2=(1000+400.4)×1.2 = 1680.48 W
So choose the cabinet air conditioner with cooling capacity of 2000W.

Cooling System

Basic Components
Air conditioner is composed of compressor, condenser, evaporator, electric control system, expansion valve and capillary tube, dry filter and fans etc.
Cooling Theory
A. The compressor takes in the gas refrigerant from the evaporator and compresses it into high temperature and high pressure then sends it into the condenser. The refrigerant will release heating in the condenser and then the cold high pressure liquid goes through capillary throttling and turns into low temperature and low pressure
and then flows in to the evaporator. The refrigerant will absorb heat and then turns into gas in the evaporator. Thus forms the cooling cycle system.
B. The condenser and evaporator has circulation fan to enhance air convection and heat exchange efficiency. The heat exchange between condenser and air is outside the control box and that of evaporator and air is inside the control box.
C. The electrical system is mainly monitoring the temperature of the cooled closed cabinet and controls the cooling circulation by setting temperature.

Air Conditioner Operation

Check before Operation
Please check the following after the electrical and air conditioner installation:
a. No barrier before air inlet and outlet.
b. The air conditioner is installed vertically, and all mounting screws have been tightened.
c. Air conditioner drain has been securely mounted and connected with the drain line cabinet (optional).
d. Connecting power cord has been connected reliably.
e. Fans can freely rotate with no strange noise.
f. AC input voltage matches with the contents of the nameplate parameters
Start to Operate
a. Turn on the power breaker and start running.
b. AC input power closed, the inside fan runs. If the inside temperature reaches the operation conditions, the cooling and heating systems start to operate. When the cooling system starts to operate, the outside circulation fan is controlled by condenser thus it will start after the compressor.

Fault Analysis & Handling

After power on, the cabinet temperature is higher than setting temperature and the air conditioner doesn’t work.| 1.Check the power supply and circuit. 2.Contact professional people for help.
The air conditioner runs normally but the cooling effect is not ideal.| 1.  Choose another air conditioner or correct cooling capacity according to the heat loading.
2.  Make sure the air conditioner works within its normal working temperature range.
3.  Contact professional people for help.
**** The air conditioner runs normally, it suddenly stops cooling and no electrical control system failures.| **** 1.Normal phenomenon. It monitor the temperature inside the cabinet temperature and then decides whether star or stop cooling according it. 2.Contact professional people for help.
The air conditioner runs normally, it suddenly stops running
with no electrical control system failures.| 1.  Check the power supply.
2.  Contact professional people for help.

Notes :

• Please install leakage circuit breaker
• Do not put your fingers or objects in the air outlet because the running air conditioner will cause injury to human beings or damage to the air
• Do not repair without
• The air conditioner can not be inverted in any case, otherwise it may cause damage to the
• Try to remain stable during handling The tilt angle should not exceed 45 degrees.

Check and Maintenance

Regular Inspection
A. Check whether cabinet air conditioner power supply wire and communication wire is ok or not;
B. Check whether cabinet air conditioner running is normal, whether the air inlet and air outlet mouth temperature difference is obvious when starting refrigeration system;
C. Check whether fan and compressor work normally and whether there is obvious noise or shake;
D. Check whether mechanical structural parts are damaged or deformed;
E. Check whether air conditioner inner and outer circulation air inlet and outlet, cabinet outer protective cover air inlet and outlet screen are jammed;
F. According to the actual air quality, please arrange maintenance personnel to inspect cabinet air conditioner every 3-6 months;
Regular Maintenance
During air conditioner running, dust may cover on the fins of heat exchange, which may affect the heat exchange and even cause degradation of air conditioner performance seriously. It is suggested to clean and maintain heat exchange for each 3-6 months. The cleaning and maintaining interval depend on the air pollution and running time in different regions. When cleaning, do not use hot water or gasoline and other organic solvent
