General description

The YLCC water chillers and YLCC-H heat pumps are supplied 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 follow a quality control process in accordance with the ISO 9001 standard, which is also demanded from the acquired components.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 processes that require cold (or hot) water or water with glycol. Designed for indoor installation.

Technical specifications

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. Starting will be direct on line. With electronic control. The crankcase 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 (standard 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 different 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,

connected and tested.The electric box has a door with a blocking mechanism and contains the compressor and fan contactors, fuses and electrical protection. Also has IP44 protection.

Centrifugal fans

Transmission is by belts and removable core pulleys. The motors are mounted on tensing bases fastened directly to the fan casing.

Two versions are available: with horizontal or vertical air discharge

Controls

So as to achieve maximum energy savings, perfect operation of the equipment and prolong the useful life of same, the YLCC water chillers or heat pump units are equipped with the following controls:

-Electronic thermostat that controls cold water return temperature.

-Electronic antifreeze thermostat.

-High pressure switch, 31 bar.

-Low pressure switch, 2 bar.

-Stage rotation (included in the thermostat).

-Remote terminal unit (optional).

-Timed start.

-Remote control.

Compatible with the following units:

GH200	for size 42
GH260	for sizes 62 and 82

Accessories

Hydro kit GH

Includes: Buffer tank, automatic air purger, pressure gauge, automatic 1.5 bar filling valve, expansion vessel, pump, flow switch, drain valve, safety valve and electronic board for interconnection. Available in 200, 260 and 600 litre capacities. There are two versions of GH600: GH600S and GH600P.

DI buffer tanks

Cylindrical shape and in vertical position. Available in 200, 260 and 600 litre capacities.

Low ambient kit (factory-mounted, optional)

This accessory allows operation of the unit when the condensing outdoor air temperature is below 10° C.

General information

This accessory controls condensing pressure in the winter cycle by varying air flow through the outdoor coils. This flow variation keeps condensing pressure constant when outdoor temperatures are low.

Operation

By means of the pressure detected through the analogical pressure switches installed in the cooling circuit, and carrying out the appropriate calculations as programmed, this control generates an analogical signal that opens the dampers to maintain the condensing pressure previously programmed as the set point.

Anti-vibratory supports

Whenever a maximum reduction of vibration and noise generated by the unit is required, a set of steel spring anti-vibratory supports can be used.These should be installed between the supporting frame of the unit and the base or floor where same is to be located. This base should be solid and sized in accordance with the weight to be supported. 12MA bolts are use to secure the supports to the base of the frame.This antivibratory support accessory for YLCC-42/62 includes 4 springs, whereas forYLCC-82/102/122/152 it includes 6.These spring supports should be distributed and secured by means of the corresponding holes drilled in the chiller base, the location of which is detailed in General Dimensions.

Remote control (accessory)

For access and control by means of the buttons and LEDs available. Allows selecting the cool, heat and OFF functions, and the red LED indicates any failure.

Can be installed at a maximum distance of 50 m.The remote terminal should be connected to the unit with a 7 x 0,35 mm2 cable.

Flow switch (optional accessory)

Flow switch

Switch with a 1" MPT thread, adequate for a Design Operating Pressure of 10 bar hand so as to protect the equipment against water flow drops. This switch, or an equivalent, is required for the site installation of each unit (obligatory).

Remote terminal

For total access and control of the system by means of the display, buttons and LEDs. Allows selecting cool, heat and off functions. Can also modify operating parameters and monitor the system. Can be installed at a distance of 150 m.

Factors with water and glycol

Glycol can be used for antifreeze protection, or as brine for operation at low temperatures. We recommend the use of water and glycol when the discharge water temperature is below +6° C. The “Solution with glycol/freezing point” table gives the freezing point of water with glycol, and the “Recommended glycol concentration” table shows the glycol concentration needed, depending upon application.

Glycol contains anticorrosive and antifoam components that favour circuit protection.

Solution with glycol/freezing point

% Glycol weight per weight	Freezing point °C

10	-4
20	-10
30	-17
35	-20
40	-25
50	-37

A mixture of glycol and water has a freezing point below that of pure water. Depending upon the concentration of glycol in the solution, an even lower freezing point can be achieved and this protects the circuit when the unit is off and ambient temperature is low (below 0° C).This table indicates freezing point in accordance with glycol concentration. This concentration appears in % per weight.

Recommended glycol concentration

LWT °C	Glycol % per weight
6°C > LWT > 0°C	20
0°C > LWT > -5°C	30

The glycol concentration in the water should be checked regularly to ensure adequate protection of the chiller.
