4. Feature & Benefit

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 be easy for maintenance.
(It’s OK for 1000 hours salt spray test)
2. The adoption of credible protection system
2.1 The protection for compressor
High-pressure protection, low-pressure protection, compressor current protection and so on the series’ protectors can ensure compressor operating normally. Adopts independent system, except for protections of sequence and wire control output, any protection relate to its corresponding compressor. Once a compressor protection energized, the corresponding compressor will stop, others are still working.
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 technical 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.
Nice compressor control
Compressor staging is controlled directly by the indoor temperature. When the indoor temperature is warmer than the setting, cooling is staged up; when the indoor temperature is cooler than the setting, cooling is staged down. However, a stage change can only occur when the indoor 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 fin, the condenser has high-efficient heat exchanger, the energy waste decreases greatly.
3.3 Evaporator
By using the high-efficient, super thin fin and inner-whorl 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 control systems and refrigerant cycle system, the capacity output is adjusted
automatically depending on different demand, save energy when one control system is in running according to low capacity output.

Flange
4. Optional collocation
4.1 Operation in high temperature
The air-conditioner designed for high temperature can run until 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 port.
The external pressure gauge port, which is identified permanently and clearly the embossed wording, H is high pressure connection and L is low pressure connection. With the gauge port mounted externally, an accurate diagnostic for system operation can be quick and easy 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 Function

5.1 Standard specification
A. General
The Packaged cooling or combination heating and cooling unit is suitable for mounting on the roof or ground. The packaged unit consists of scroll compressors, evaporator coil, condenser coil, control wiring and interconnecting piping- all factories assembled and mounted on heavy gauge G-90 galvanized steel sheet press formed base, ready for field connection to utilities and ducts. The packaged unit is of rigid construction with holes provided in the base rails for overhead rigging. The unit is provided with an integral weather resistant control panel. These units are rated and tested in accordance with ARI standard 210/ARI 360.
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 ASTM A 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). 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. Return bend has 0.022 inch thickness (0.56mm). 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. Fan wheels shafts and bearing are selected to operate at 25% below first critical speed. Pillow block bearing are selected for at 200,000 hours average life at design operating conditions. Shaft is turned, ground and polished from solid
