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.
