1. YDS system series
1.1
What is YDS
The YDS (YORK Digital Scroll Air Conditioner) air conditioning system is operated by a
variable-capacity compressor and is accommodated by multiple evaporators (indoor units). It is
considered as the next-generation modular system with high efficiency air conditioning in the
world.
It has undoubtedly changed the face of cooling associated with high-storied buildings. It
provides a broad range of different applications for settings such as offices, hotels and schools.
With the advantage of easy installation and simple controlling system and so on, the YDS system
can meet the demands of the air conditioning market better.
1.2 Features of YDS
(1) Variable compressor
The world’s first PWM (Pulse Width Modulation) compressor controls the cooling and
heating capacity automatically according to the load.
Principle of the digital scroll compressor:
[1] Composition
The solenoid valve is installed for the compressor’s loading/ unloading between the upper
part of the fixed scroll and the suction pipe.
[2] Mechanism
a. When the solenoid valve is turned off, the fixed scroll is close to the orbiting (Loading).
b. When the solenoid valve is turned on, the fixed scroll is separated from the orbiting
scroll. (Unloading)
