YDS Variable refrigerant flow system

Variable capacity operation and energy saving

By using high technology digital type Scroll

compressors, a constant energy control of between

10% and 100% can be achieved while maintaining a

greater energy efficiency ratio (EER) when operating

at low charges. This is a design with a high degree of

energy efficiency.

Independent and economic controls

All indoor units can be controlled independently, thus

giving stable and excellent performance. Therefore,

the indoor units do not affect each other and can easily

avoid unnecessary expenses.

Easy, practical, economic installation that saves space

This installation does not require a circuit for oil

refrigeration. One or more outdoor units can be

located directly on the roof/terrace.

The interconnecting tubing can save you installation

expenses and space. And maintenance is easy.

Flexible combination of indoor units

Each outdoor unit allows connecting up to 16 indoor

units, this amount depending upon the model. The

total capacity of the indoor units can vary between 50%

and 130% of the outdoor unit nominal capacity.

11,0-14,0 kW

The Digital Scroll Compressor uses a simple and

effective method to modulate the capacity of an AC,

giving unparalleled performance in the modulation field.

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 flow, and the unloaded state, where there

is not capacity and mass flow. During the unloaded

state there is a separation between the scrolls. Once the

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.

Intelligent technologyComfortable and pleasant intelligent temperature control.

The advanced temperature control system maintains the indoor

ambient temperature at a precision of 0.5 C. This precise

temperature control improves the feeling of comfort.

The different indoor units have diverse charges that are

measured by the control system, and refrigerant quality

distributed to each one of the indoor units is calculated and

controlled by the microprocessor, so that each indoor unit may

satisfy all individual needs.

YORK System YDSThe YORk system with Digital Scroll is working like the VRF

principle and offers you economical air-conditioning system for

projects, which are requiring more capacity than the normal split

and multi split solutions.

The lengths for the connecting tubes between the indoor and

outdoor have been prolonged, which brings you more flexible

solutions for complex air-conditioning projects.
