3 Technical characteristics TEAL FC Free Cooling water chiller Blue Box FREE COOLING units meet the growing needs of energy saving, being designed to reduce the operating costs of the refrigeration equipment that operate for longer or shorter periods of the year, at low ambient temperatures. The strong point of Free Cooling units is definitely the control system that allows complete exploitation of the external air as a free resource, thereby minimizing the energia consumed by the compression system. Giving priority to energy saving, the control enables the most appropriate operating mode according to the measurements made by the temperature probes on the external air and reference water. In fact, the Free Cooling coil is connected in series with the evaporator of the refrigeration circuit and a three-way servocontrolled valve allows bypassing the same coil when its efficiency is too low due to high external temperature. Vice versa, if the weather conditions are favourable, the Free Cooling coil provides cooling of the secondary fluid using the external air, reducing the compressor wear. This way, to decrease the room temperature, the power absorbed is reduced until only the Free Cooling fans are used. Operation The chart shows the progress of the power consumption according to external air temperature while maintaining a constant cooling capacity of the unit. Condensation control needed during the simultaneous operation of the refrigeration and free cooling system is achieved by modulating the fan rotation speed according to condensation pressure and by a fan speed phase cut controller installed as standard or using an EC Accessory for the condensing section. Indicative values of power absorbed per Free Cooling CUSTOM unit % of maximum capacity External air temperature ( C) 3

4 FC circuit diagram Summer The cooling capacity is generated by compressors; in fact, the room temperature is higher than the temperature of the water and glycol solution of the system recovery circuit. The free-cooling coil and the relative fans remain idle. The operation is the same as a classic compression chiller. CHILLER SECTION ACTIVE The fan speed controller operates according to the needs CHILLER FREE COOLING TURNED OFF 30% energy savings in fan capacity against FC units with coupled coils Spring and autumn period The cooling system in free-cooling mode works in conjunction with the mechanical cooling system. The free-cooling is automatically activated when the external air temperature is lower than the temperature of the water and glycol solution in the recovery circuit. The solution is partly cooled by the freecooling coil using the external air; the rest of the cooling capacity required is obtained mechanically by reducing the compressors, thus achieving more significant energy savings when cooling the room temperature. CHILLER SECTION ACTIVE The fan speed controller is ON CHILLER FREE COOLING ACTIVE fans operate at maximum speed Winter Depending on the charging conditions, bellow a certain value of the external temperature, the cooling unit work exclusively in free-cooling mode: the solution is cooled completely by the free-cooling coil; compressors and fans of the condensing section are turned off. For even more stringent external air temperatures, some of the free-cooling fans will be turned off gradually to avoid excessive cooling of the water / glycol solution. With the addition of the fan EC free-cooling accessory, the air flow regulation is achieved through continuous modulation according to the reference temperature, resulting in energy savings. CHILLER SECTION TURNED OFF 30% energy savings in fan capacity against FC units with coupled coils CHILLER FREE COOLING ACTIVE With ON / OFF fan control as an accessory, the EC fans provide further energy savings 4

5 Energy analysis Below are some charts illustrating the energy savings for different cities, in terms of energy consumption, achieved using TEAL FC, in comparison to the correspondent standard unit, assuming that the cooling need is constant throughout the year. Such energy savings can be easily monetized according to the electricity tariff in the country in which the machine will be used, because the investment is recovered within a year in most cases (under specified conditions). The energy savings of the subsequent years result in net profit for the investor. The charts show that for cities with a harsh climate there is a significant reduction of energy consumption, the latter still remains high even in countries with milder climate. In order to determine the investment payback, we also add the power tariff in the country where the machine is installed.

10 Chiller versions TEAL Compared to TEAL standard version, this unit includes smaller sizes of compressors and increased heat exchangers in order to increase the exchange surfaces and compressor potential ratio. This provides greater energy efficiency ( high EER and COP) and high ESEER (European Seasonal Energy Efficiency Ratio) values. TEAL+ Compared to TEAL, this unit provides further increase in the exchange surfaces and compressor ratio. This results in very high energy efficiency. TEAL SLN In addition to the /LN version compressor tank with acoustic insulation, this unit is able to reduce the fan speed in order to achieve lower air flow and, therefore, lower noise level, under standard operating conditions, with respect to the basic version unit. The speed controller allows the fans to rotate at maximum speed even when the outdoor air temperature is particularly critical and, therefore, have the same operating limits as TEAL.

The speed controller allows the fans to rotate at maximum speed even when the outdoor air temperature is particularly critical and, therefore, have the same operating limits as TEAL+. Night Shift System Accessory This accessory is available for TEAL SLN FC and TEAL SLN FC and allows the units, by setting the daily time slot, to operate in high efficiency or low noise mode, depending on the requirements. For example, in the daytime during the summer, the machine can be set to operate at full energy efficiency, while at night, the machine will run in super low-noise mode, with great sensitivity to noise perception. From the default time slot settings below, the user can reset the new time slots directly from the keyboard of the microprocessor Default time slots From 8:00 to 20:00 High Efficiency Mode From 20:00 to 8:00 Super low-noise Mode 10
