省電 Adjust the inverter compressor’s output according to the cooling/heating load resulting mass amount of energy savings.DC inverter control used is even more energy-saving than AC variable speed control

Energy Saving

Commercial/Industrial useInverter Air Conditioning System

MAIN FEATURES

Wide Range of

Application Widely used in offices, residential blocks, commercial areas and hotels etc.High coordination between indoor and outdoor units.

2

Sine-wave driven inverter having lower noise.R410a refrigerant is used which has low ODP value.DC motor for indoor units which has higher efficiency.Using electronic expansion valve (EEV) high system performance is maintained.

High

Performance

Human

Centered High precision micro-computer control that is able to maintain the room temperature difference to less than 1℃.Instant cooling/heating, human-centered function raising space comfort.

Low-noise indoor unit providing higher comfort.Inverter compressor reduces output during low load condition while the fan of outdoor unit lowers its speed to reduce noise.

Low Noise

Performance

May select wielding or bolt-and-nut connecting method for piping.Lower space utilized, easier installation.Multi-stage capacity for indoor unit in order to match the space loads.

According to the

thermostat

settings of the space, instant

and high efficiency operating

mode of compressor control

can be achieved via smart

microcomputer’s PI calculation

program, hence providing a

more comfortable space and

environment.

The air-conditioning units

control the space to constant

temperature. This control

enables the units perform in

high-efficiency operating

mode. Hence much energy and

the cost can be saved.

SYSTEM CONTROL PARTS

Using high pressure sidepressure sensor to examine,high precision and wide range,also complete surveillance.

Calculate according to spaceload and refrigerant pressure to provide highefficiencyoutput.

Pressure Sensor

The indoor unit uses DC fanmotor which the efficiency is 60% higher than that of AC motor. Hence more energy is saved.

Multi-stage control is provided for fan speed hence provided comfortable environment.

DC FanMotor

EEV

EEV is used for the whole series.It is high precision flowcontrol, highly stable.

Adjust the opening according to mass flow and temperaturechange in order to achieveoptimization.
