Digital Scroll Compressor operation
The Digital Scroll Compressor uses a simple and effective method to modulate the capacity of an AC, giving unparalleled performance in the modulation feld.To modulate the capacity the Digital Scroll operates in two stages, the “loaded state” in which the compressor works as a normal Scroll compressor at full capacity and mass fow, and the “unloaded state”, where there is not capacity and mass fow. During the “unloaded state” there is a separation between the scrolls. Once th scrolls separate, any gas passing through is no longer compressed. Changing the cycle time (“Loaded state” time and “Unloaded state” time) determines the capacity modulation of the compressor.
The biasing chamber communicates with the by-pass circuit. When the compressor is in the loading state, the pressure inside the biasing chamber is equal to the compressor’s discharge pressure, as the PWM solenoid valve keeps separate the two segment of the by-pass circuit between the biasing chamber and the suction pipe (see figure). In this situation the “loading”geometrical configuration is possible as the stator is pressed down by the compression’s pressure itself.
Depending on thermal load conditions,for cooling or heating operations, the PWM solenoid valve (2-ways), opens theby-pass circuit, thus allowing the communication between the discharge and suction sections. In this way the respective pressures become equal and coincident to the suction pressure. The pressure in the compression chamber no more self-balanced, (self-balancing due to the presence ofthebiasingchamber), pushes the stator upward,producing a circumferential port, thus opening the compression chamber . So the previously described “unloading”configuration, is achieved.
FAN
axial type aluminum (80/100) or ABS plastic(othermodels) fans with direct drive motor. All fans are statically and dynamically balanced for quiet operation.
Intelligent technology
Comfortable and pleasant intelligent temperature control. The advanced temperature control system maintains the indoor ambient temperature at a precision of ± 0.5º C. This precise temperature control improves the feeling of comfort. The different indoor units have.
Range of Operation
TOYO digital scroll DX is more energy saving than inverter VRF
1. General Power Loss
- Under unload status, the energy consumption of TOYO digital scroll DX system is about 10% of the rated one, and there’s no power loss under loaded status, thus the total power loss of York digital scrol
2. Part Load Condition
- Capacity modulation range of TOYO digital scroll dx system is 10%-100%. For a typical 5HP system the lowest capacity is 5HP*10%=0.5HP. Even when there’s only one small indoor unit (1HP) is running, the whole system can operate properly without any bypass.
- Normal inverter compressor’s capacity modulation range is 33%-107%. For a typical 5HP system, the lowest capacity is 5HP*33%=1.65HP. When there’s only one small indoor unit (1HP) is running, system bypass is required which will reduce the efficiency.
3.High Ambient/ High Load Operation
- Since the compressor speed is constant, TOYO-AC digital scroll DX system can operate properly under high ambient/ high load conditions.
- For inverter VRF system, the discharge temperature will rise rapidly under high speed operation, and liquid refrigerant cooling is necessary to protect the compressor and reduce the efficiency at the same
