1. YDS system series 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.

General information ___________________________________________________________________________________ c. This process controls the On/Off time of the valve and the rotating refrigerants in the circle thus adjusting the capacity. d. The cooling capacity of the outdoor units is adjusted automatically, according to the number of operating indoor unit(s). [3] PWM (Pulse Width Modulation) Valve PWM valve is the valve to take away the fixed scroll by lifting up through the difference of pressure after the digital scroll compressor being connected to the outlet and inlet of suction.

General information ___________________________________________________________________________________ (3) High efficiency EER is up to 3.2. (4) Long & single piping system Digital scroll system is the only system that is free of oil separator and oil recycling equipment. In the loading state, the speed of the refrigerant is enough to move oil back to the compressor.
Page 12
General information ___________________________________________________________________________________ (5) Advanced oil return technology. Combining the electronic control and the mechanical control, the oil level controller keeps appropriate oil level in the compressor crankcase. Equipped with oil balance pipe and low-pressure accumulator, it is applicable to both low-pressure & high-pressure oil cycling system.
Page 13
The structure of the YDS system and the piping work are simple, thus the installation is easy. Indoor units installation: Whole series indoor units have the same gas/liquid connection size for R-410A ,and by flare nut connection, it is easy to connect and decrease your installation cost up to 30%. Independent system The YDS system can be installed by stages and the owners can install their system at their convenient time.
