At Articae we give a personalised treatment to the client and we continuously update our developments, which allows us to introduce new templates, refrigerants and control algorithms for new installations, based on the client’s needs, at the same time as we can be more competitive and more efficient.

Please contact us through the contact form, and in a short period of time we will contact you in order to study your particular case.

If there is only one refrigerant circuit, it is sufficient to measure the temperature and pressure upstream of the compressor inlets and the temperature and pressure downstream of the compressor outlet junction. The electrical power can be measured jointly for all compressors, which will give an overall compression efficiency.

If there is a physical impossibility, it can also be done individually for each compressor. The electrical power can be measured for each of the compressors, which will give an individual efficiency for each compressor and an overall efficiency for all compressors. However, it is advisable that the customer informs us of this beforehand, so that we can develop a template and visualisation tailored to his needs.

If the circuit has a suction gas heat exchanger, the PilotE² HVACR unit reports by default the COP and EER, which are calculated from the useful heat or cooling of our process, i.e. without taking into account the heat exchanged in the suction gas heat exchanger. However, it is possible to develop a template that allows a visualisation of different performances depending on the customer’s requirements.

No, it is not necessary. PilotE² HVACR uses the laws of thermodynamics to perform the energy balance and obtain the efficiencies without the need to measure any flow rate or intrusive measurements in the refrigeration or heat pump circuit.

All the program assumes is a combined thermal and electrical efficiency of the compressor of 93%. This estimate is close enough for most hermetic and semi-hermetic compressors, without any external air or liquid cooling, such as water or oil.

For complex cases, Articae will offer as an additional service the study and further development of each particular case.

Of course. Since the network analyser sends the data wirelessly via Modbus RS485 to the PilotE², several compressors can be measured at the same time, even several circuits at the same time, by incorporating as many wireless analysers as necessary. Each analyser can measure up to two three-phase circuits.

There is also the option of measuring temperatures and pressures wirelessly, via Modbus RS485, with the corresponding gateway.

All you need is a computer, mobile phone or tablet with internet access. With a customer-specific username and password, the installation can be monitored in real time and historical data of different variables can be observed.

This may be because the temperature or electrical power is outside the measuring range of the probes, so the error may be significantly higher than the error given by the probes.

PilotE² HVACR can work with different probes of different temperature, pressure or current ranges to best suit the customer’s particular case.
