Developing from traditional split type air conditioner.


There are two ways to achieve VRV

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]1. INVERTER Technology (Electric Adjustment):

Air-conditioners bearing the inverter tag use a variable-frequency drive to control the speed of the motor and thus the compressor. The variable-frequency drive uses a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency. The AC current is used to drive a brushless motor or an induction motor. As the speed of a brushless motor is synchronized to the frequency of the AC current, it is thus possible to build a compressor that can be run at different speeds. Similarly, the voltage and frequency can be varied as needed to efficiently run an induction motor at different speeds. A micro controller can then sample the current ambient air temperature and adjust the speed of the compressor appropriately.

2. DIGITAL SCROLL Technology (Mechanic Adjustment):
Variable capacity adjustment is achieved by PWM (Pulse width modulation valve) to maintain a balance between demanding and providing.
This optimal force, which holds the 2 Scrolls together at all operating conditions, ensures high efficiency of Copeland Scrolls.
The Digital Scroll operates in two stages – the “loaded state”, when the solenoid valve is normally closed and “unloaded state”, when the solenoid valve is open. During the loaded state, the compressor operates like a standard scroll and delivers full capacity and mass flow. However, during the unloaded state, there is no capacity and no mass flow through the compressor. At this stage, let us introduce the concept of a cycle time. A cycle time consists of a “Loaded State” time, and “Unloaded State” time. The duration of these 2-time segments determine the capacity modulation of the compressor.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_video align=”center” video_thumb_image=”2418″ link=”https://youtu.be/_XF0XefAyz8″][/vc_column][/vc_row]
