4. Features

1. The adoption of anticorrosive-box

The reinforced anticorrosion by using galvanization armor plate and coated with man-composed paint.

The appearance is stylish and easy for maintenance.

(Has been passed 1000 hours salt spray test)

2. The adoption of credible protection system

2.1 The protection of compressor

High-pressure protection, low-pressure protection, compressor’s current protection and so on.The series’ protectors can ensure compressor operating normally. It adopts independent system, except for protection of sequence and wired controller output, any related protection to its corresponding compressor. Once a compressor protection energized, the corresponding compressor will stop, the others working still.

2.2 Fan motor

The fan motors for evaporator have over-heat protection and over-current protection function. The fan motors for condenser have the temperature controller protection function.

3. Energy saving design

3.1 High efficiency compressor

Using professional compressor, heat exchanger and optimum connection pipe, the compressor can

startup under low power input. Provide maximum reliability, efficiency and quiet operation. Two refrigerant circuits on larger units (above 12.5ton) provide efficient part load performance. Standard low and high pressure safety switches.

Well compressor control

Compressor staging is controlled directly by the control temperature. When the control temperature is warmer than the cooling set point, cooling is staged up; when the control temperature is cooler than the cooling set point, cooling is staged down. However, a stage change can only occur when the control temperature is outside the dead band. Staging is constrained by an inter-stage delay timer. These constraints protect the compressors from short cycling while eliminating temperature variations near the diffusers.

3.2 Condenser

By using high-efficient thin wing, the condenser has high-efficient heat exchanger, the energy waste decreases greatly.

3.3 Evaporator

By using the high-efficient, super thin wing and inner grooved copper pipe, the evaporators get the higher capacity and the lower noise level.

3.4 The heat insulation of indoor unit

The heat insulation of indoor unit can availably decrease heat loss.

3.5 The control and refrigerant cycle system There are two independent refrigerant cycle systems, the capacity output is adjusted automatically by

different demand, save energy when one control system is in running according to low capacity output.

4. Optional collocation

4.1 Operation in high temperature

The air-conditioner designed for high temperature operating, even when the ambient temperature reaches up to 52℃（125℉）.

4.2 Strong air flow

Large air volume from the air inlet is forced ventilating by the condenser fan.

4.3 Minimum installation arrangement

The installation is fast and low cost with the easy installation and ready operation.

4.4 Pre-drilled duct flange

Flanges are prepared at the supply and return duct connections so that they can reduce duct connection work at site.

4.5 Quiet operation

Noise and vibration have been effectively reduced by adopting new style hermetic compressor. The centrifugal fan and fan casing are optimum shaped for efficient and low noise operation.

5. Cabinet

5.1 Sloped drain pan and drain pipe.

5.2 Cabinets have forklift and lifting holes for easy transportation.

5.3 Cabinets have fresh air function, and the filter can be washable.

5.4 External pressure gauge ports.

With the gauge ports mounted externally, an accurate diagnostic of system operation can be performed quickly and easily without disrupting airflow.

5.5 Durable construction.

Weather-resistant construction with capped seams and sloped top panels. G90 galvanized heavy gauge plate conforming to ASTM-A-653, Zinc content of

galvanized plate is 275 g/m2 .

5. List of Functions

5.1 Standard specifications A. General

The units are convertible airflow. All units shall be factory assembled, internally wired, fully charged refrigerant and 100% run tested to check cooling and heating operation, fan and blower rotation, and control sequence before leaving the factory. Wiring internal to the unit shall be colored and numbered for simplified identification. The unit is provided with an integral weather resistant control panel.

B. Unit enclosure

Panels are of heavy gauge, G-90 galvanized steel sheet with removable access panels, completely weatherized for outdoor installation and properly reinforced and brazed. Panels and access door are provided for inspection and access for all internal parts. Enclosures are provided with adequately reinforced points of support for setting in the unit. Steel sheet panels are zinc-coated and galvanized by the hot dip process of lock forming quality conforming to ASTMA 653 commercial weight G-90, followed by baked on electrostatic polyester dry powder coat paint, on all external panel.

C. Compressor

Compressors are scroll for all the models. They are provided with all the standard controls and accessories necessary for safe operation. These are equipped with internal motor protector; factory installed crank case heater and rubber vibration isolator for quiet and efficient operation.

D. Air-cooled condensing section

1. The air-cooled condensing section is enclosed within the unit housing and consists of condenser coil, fan(s) electric motor(s) and inherently protected compressor(s). Inner grooved copper tubes with wall thickness of 0.3mm, mechanically bonded to enhanced louvered aluminum fins are standard for all condenser coils. As an option, enhanced coated aluminum fins may be provided. Tube support sheets are galvanized steel, formed to provide structural strength.

2. Fans are propeller type, direct driven, upward discharge and provided with fan grille mounted on the casing.

3. Motors are totally enclosed air-over type with class F insulation. Inherent thermal protection is automatic reset type.

E. Evaporator coil section

1. All cooling coils are of enhanced louvered fins and inner grooved copper tubes with wall thickness of

0.3mm, mechanically bonded to aluminum fins. As option, enhanced coated aluminum fins may be

provided. Tube support sheets are galvanized steel, formed to provide structural strength.

2. Drainage pan: An insulated drainage pan made of G-90 galvanized steel is provided, for additional corrosion protection.

3. Insulation: Insulation is supplied in adequate density and thickness for all units to prevent condensation from forming on the unit casing. Insulation meets the requirements of NFPA 90A and is protected against deterioration and erosion from air currents.

F. Evaporator fan

Evaporator fan is of centrifugal forward-curved blade design capable of handling total required CFM and

static pressure in the low and the medium ranges. Casings are made of galvanized steel. Blower motors are of open drip proof type (totally enclosed types are optional) and conform to NEMA MG-1 and MG-2. Blower motor is mounted on adjustable base and secured by locking device. Pillow block bearing are selected for at 200,000 hours average life at design operating conditions. Shaft is turned, ground and
