The whole production is subject to the summer / winter mode of the general control, as well as the selector switch and schedule of the same.
Each pump and electrovalve element has a selector switch (Manual / Stop / Automatic) to directly govern the equipment, for maintenance tasks and solutions of possible incidents that may appear.
Following there is a list of possible improvements in each of the different elements involved:
Another possible improvement in air conditioners is the regulation of the motors of the impulse and return fans by means of a drive, depending on a sensor of differential pressure of air.
To finish, another useful system, is to have dirty filter indicators, because a dirty filter implies an increase in the electrical consumption of the installation.
Heat Production
This double regulation of temperature is also applicable when we have a boiler without possibility of changing temperature setpoint, but we have mixing valves to lower the temperature we drive to the circuits.
The following screen would be an example of temperature curve of impulsion as a function of outside temperature:
The majority of chillers can be questioned using lonworks, bacnet or modbus protocols, so they will let us know all their control variables such as temperatures, pressures, setpoints, alarms, etc.
