York YLCC-h, 122, 152 manual Nomenclature, General characteristics, Mechanical specifications

General description

The YLCC water chillers and YLCC-H heat pumps are sup- plied factory-assembled and with all refrigerant piping and interconnecting wiring ready for installation at the job site. After assembly, the water chillers go through a water test. Possible leaks are also checked once the refrigerant is charged.

The units are made of galvanized steel with anticorrosive nuts and bolts. The panels can be removed for access to internal components. The outer galvanized steel parts are painted with oven-dried enamel (RAL 9002).

Throughout the manufacturing process, all our products fol- low a quality control process in accordance with the ISO 9001 standard, which is also demanded from the acquired compo- nents.The PED pressure equipment directive is also applied. The water chillers or air-water type heat pumps are designed to be installed in air conditioning systems or industrial proc- esses that require cold (or hot) water or water with glycol. Designed for indoor installation.

General characteristics

The main characteristics of these units are:

-Operating test at factory.

-Ready for job site installation.

-Electronic control of water temperature.

-Two independent circuits (2 stages up to 102) (4 stages 122 and 152).

-Scroll compressors.

-Centrifugal fan (horizontal or vertical air discharge).

-Coaxial exchanger.

-R-407C refrigerant.

-Hydro kit (option).

The accessibility of all components and control system al- lows quick installation and start-up, as well as trouble-free maintenance.

Mechanical specifications

Casing

Made of zinc-coated aluminium steel sheeting, finished with oven-polymerised powdered paint, colour RAL 9002. it may be installed directly outdoors.

Their extraordinary protection against corrosion, along with their heavy duty internal structure, make up an extremely robust and resistant unit.

Compressor

The hermetic Scroll compressor is protected internally. Start- ing will be direct on line. With electronic control. The crank- case heater is activated when the compressor is inoperative. Mounted on anti-vibratory supports.

Evaporator (water)

Coaxial type exchanger, of a large transmission surface, made of finned tubing. Insulated externally.

Maximum operating pressure is 25 bar on the refrigerant side, and 10 bar on the water side.

Condenser (air)

Of a large surface. Made of copper tubing in staggered rows, mechanically expanded within high performance aluminium fins. Maximum operating pressure of the coil is 28 bar (stand- ard unit).

Control of refrigerant to the exchangers

Refrigerant feed is carried out by means of an expansion valve with external pressure equalizer (reversible on heat pump models).

Refrigerant

The units are supplied with an optimum R-407C refrigerant charge for correct operation and maximum output under dif- ferent working conditions.

Cooling circuit

Made of welded copper tubing and equipped with 1/4" SAE connections on the high and low pressure sides.

This product has been designed, manufactured and tested in accordance with the strictest European safety regulations. Includes the following components:

-Suction accumulator (heat pump only).

-Filter-dryer.

-Expansion valve.

-4-way valve (heat pump only).

-Liquid sight glass.

-Liquid accumulator (heat pump only).

-Automatic high and low pressure switches.

Electric and control panel

The electric and control components are factory-controlled,
