WORKING LOGIC

The control of temperature and humidity conditions, with very small tolerances, are obtainedwith a proportional working logic of the system which provides continuous anduninterrupted operation of the compressor (H) (MAN ON set on microprocessor) for thesimultaneous production of cooling and heating.

Temperature control:During cooling phase the system produce only sensible cooling, without dehumidification

This is done by raising the expansion temperature by increasing the fan speed automatically(by 0-10V proportional signal from microprocessor) and by hot gas injection in the evaporatingcoil (B) though the valve (M) until you cancel the latent component of the cooling produced bythe evaporating coil.

Any excess of cooling is canceled by the proportional hot gas reheating system (C+I) thatuses the hot gas from the compressor to reheating the air flow.

The accuracy of the hot gas reheating system is obtained through a proportional valve withcontinuous control (I) directly driven by 0-10V proportional signal from microprocessor.

The excess of condensation heat, not used by the hot gas reheating system, is exhausted bythe condenser (U).

• DX version: remote air cooled condenser equipped with axial fans and modulatingcondensing control system. Condensers are also available with centrifugal fans.

• DW version: built-in water cooled condenser equipped with 2-way modulating valvefor the water flow control.

In case of heating request, primarily using the hot gas reheating system and, if it is notsufficient, the 3 steps electric heaters (D) are activated (in combination with the hot gasreheating system).The steps of the electric heaters are very close and allow a precise temperature control.

Humidity control :In case of dehumidification request, the system automatically controls the latent coolingcapacity by producing cool with forced dehumidification through a reduction of the supply fanrotation speed (by 0-10V proportional signal from microprocessor) and closing the hot gasinjection valve (M). In this way the expansion temperature decrease and consequently thelatent cooling component increase.

Also in this case any excess of sensible cooling is compensated by the hot gas reheating colias previously described.

The humidification is obtained by the proportional steam humidifier with immersed electrodes(G). The humidifier is oversized compared to the standards used in traditional air conditioners.

NOTE : To avoid any potential conflict of the regulation control, the system always has priorityon the control of temperature.Only after reaching the temperature set-point the system begins to control the humidity.

TYPICAL INSTALLATION DIAGRAMS FOR DIRECT EXPANSION MACHINES

WITH REMOTE AIR COOLED CONDENSER

WARNINGIt is necessary to provide the refrigerant charge for the connection pipes and for theremote air cooled condenser.

Charge refrigerant in the suitable quantity and lubricant oil in 10% ratio of chargedrefrigerant.Lubricant oil must be the same type as the charged one as shown on the compressorplate.

1) Air conditioner2) Remote air cooled condenser3) Gas discharge line4) Liquid line

5) Trap. Foresee a trap every 5m of the rising pipe.6) Additional liquid receiver external to the conditioner with valves and safety valve.Suggested part in the following cases:a) refrigerant line longer than 25-30mb) plant operation with ambient temperature lower than 0°C with refrigerant line any lengthInstall the liquid receiver close to the air conditioner.

7) Solenoid valve of the liquid l ine. It is an optional accessory of the air conditioner for refrigeration plants withrefrigerant pipe longer than 10m

EXAMPLE FOR MACHINES NOISE EMISSION CALCULATION

IMPORTANTThe declared noise levels are intended in free field conditions.The noise pressure level of an installed unit is affected by the room acousticcharacteristics. Please consider an average noise increase of +4/+6 dB(A).
