Mechanical Cooling – Production of chilled water

Working limits diagram for chilled water production in Free-Cooling mode, according to the ambient temperature and chilled water inlet temperature.

PARTIAL HEAT RECOVERY Working limits for hot water production from partial heat reclaim system. The system is not regulated and the heating capacity which is supplied depends on the machine working conditions. 40÷75 °C hot water outlet temperature range 5÷15 °C Δt range between water inlet/outlet.

ANTIFREEZE MIXTURES Antifreeze mixtures have to be used when the machine working conditions foresee the chilled outlet liquid temperature below 5 °C.

OPTIONAL ACCESSORIES – LNO KIT

This optional is available as accessory to obtain a machine noise reduction. The versions equipped with LNO KIT have the following characteristics : - Set of the working parameters. - Technical compartment and panels insulated with polyurethane for sound proofing. - Cap with sound-absorbing material on each compressor. The LNO KIT allows 3 different types of set : LNO KIT 100%

No air flow reduction. Noise reduction is obtained through a different working set of the microprocessor control and an acoustic insulation of the noise source. LNO KIT 85%

Noise reduction is obtained through a different working set of the microprocessor control, an acoustic insulation of the noise source and a reduction of the condenser coil air flow at 85% of the nominal value. Consider that a condenser coil air flow reduction induces a minor cooling capacity of the machine

and a major energy consumption of the compressor.

Warning : To obtain the effective working conditions of cooling capacity and noise reduction for unit equipped with LNO KIT, please refer to the selection program.

OPTIONAL ACCESSORIES – PARTIAL HEAT RECOVERY SYSTEM

The partial heat recovery exchangers are installed on every refrigerant circuit of the machine before the main

condenser. The system is not regulated and the control is ON-OFF type. The heat recovery system’s operation is

subject to the supply demand of cooling capacity.

The system includes:

- Copper brazed plate type heat exchanger with cover plates, plates and connections in AISI 316 stainless steel. - Anticondensate insulation made of polyurethane. - Hydraulic piping.

The heating capacity which is supplied depends on the kind of refrigerant gas which is used and on working

temperatures. The heat exchangers can produce hot water up to the maximum temperature of 70÷75 °C and according

to the working conditions of the unit.
