TECHNICAL FEATURES
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.
ENERGY ANALISIS
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.
