Definitions

  • the present invention relates to an HVAC control system. More particular, the present invention relates to an HCAC control system that allows dynamic temperature control.
  • IoT Internet of Things
  • Smart thermostats need to be programmed once and then can adapt automatically to the set temperatures, depending on whether or not there are people present in a home or building, in order to save energy.
  • EP 2 769 277 describes a smart thermostat. Embodiments of EP 2 769 277 describe thermostats who can be configured to operate in one mode when the home is occupied and to operate in a second mode when the home is unoccupied. For example, when the home is occupied, devices can be configured to activate user interfaces, maintain certain levels of temperature and/or humidity. On the other hand, when the home is unoccupied, devices can be configured to turn off user interfaces, conserve power by altering normal levels of humidity, turn off appliances, and otherwise reduce power usage of the home when no one is there. Therefore, the thermostat comprises one or more temperature sensor for determining an ambient air temperature. Further, the thermostat comprises at least one occupancy sensor in operative communication with a processing system.
  • the thermostat includes an away-state feature in which the thermostat enters into an away-state mode of operation upon a determination by the processing system based on readings acquired by the at least one occupancy sensor that an away-state criterion indicative of a non-occupancy condition for an enclosure in which the thermostat has been installed has been satisfied.
  • the away-state mode of operation includes an automated setpoint temperature setback mode.
  • the processing system is configured to automatically determine, without requiring user input, whether to activate the away-state feature for the enclosure in which the thermostat has been installed.
  • the thermostat described in EP 2 769 277 can only be set in an away state and an occupancy state, i.e. a temperature setpoint for the case when nobody is in the home or building and a temperature setpoint for the case when at least one person is present in the home or building.
  • a temperature setpoint for occupancy on evenings is set at 21°, it happens that a person present in the building or home is, at that time, walking around for, e.g. cleaning the house. At that time, 21° may be too high for that person, and he or she needs to adapt the temperature, i.e. lower the temperature, manually.
  • the person may be sitting in the seat watching television. At that moment, 21° may be too low, and again, he or she needs to adapt the temperature, in that case increase the temperature, manually.
  • US 2016/0168002 relates to temporarily or permanently modifying a time-based temperature program of a programmable thermostat based on changes in the type or degree of observed or anticipated occupant activity. Additionally, the present disclosure relates to determining and implementing an activity-based temperature program that a programmable thermostat may use to control a HVAC system based on a type or degree of observed or anticipated occupant activity, rather than according to a time-based schedule. Measurements performed by sensors provide inputs to the HVAC system, that may be used to determine how many occupants may be in the structure 10, where occupants may be located within the structure, and what types and/or levels of activity these occupants may be performing.
  • the thermostats may use this sensor data, as well as other measurements or observations, to determine occupancy and/or occupant activity information and then to modify a temperature setpoint schedule for the structure 10 based on this occupancy and/or occupant activity information.
  • a processor of the thermostat analyzes the time, temperature, and occupant activity data associated with the current user input relative to the time, temperature, and occupant activity data associated with previous user inputs and attempt to identify trends. If the processor identifies a trend or correlation between the time, temperature, and occupant activity data associated with the current user input and the time, temperature, and occupant activity data associated with previous user inputs, the processor may create or modify a temperature setpoint of the temperature setpoint schedule based on the correlation.
  • the information received from the sensors or from input from a user are used to leam about the behavior of a user and to update the programmed temperature setpoint schedule accordingly.
  • US 2016/0168002 suffers from same problem as described for EP2 769 277 above.
  • the information is not used for activating a particular temperature directly when e.g. activity is detected. So, when a person is active, e.g, cleaning the house, it may be too hot, and the person will manually set a lower temperature.
  • the HVAC system will learn from it, and will later on, when this is a recurring process, adapt the programmed temperature setpoint schedule accordingly. It will thus take some time, e.g. days or months, before the HVAC system learns from this.

And according to another example, in case of the control and communication means 3 being e.g. a display, it can be provided on a wall in a room of the building. However, the location of the control and communication means 3 is not necessarily fixed.

  • the processor 4 may be adapted for receiving input for setting the presence temperature setting T PRES and the away temperature setting T AWAY via the at least one user input interface 2.
  • the presence temperature setting T PRES and the away temperature setting T AWAY may be done manually by the user. This may be done by programming the HVAC control system 10 with the preferred temperature settings T PRES and T AWAY as a function of time. In other words, the preferred temperature settings T PRES and T AWAY are activated at the programmed hour.
  • programming the HVAC control system 10 may be such that activation of the preferred temperature settings T PRES and T AWAY may be connected to the detection of the presence of an occupant. Therefore, the HVAC control system may furthermore comprise means 5 for detecting presence of at least one occupant.
  • Such means 5 for detecting the presence of at least one occupant may, according to embodiments of the invention, comprise a CO 2 sensor, means for detecting opening or closing of a door, means for detecting presence of WiFi or Bluetooth, a PIR sensor, a light measurement sensor, or any other suitable means for detecting the presence of a person in an area, e.g. room or space, of a building.
  • the processor 4 may be adapted for receiving input from the means 5 for detecting presence of the at least one occupant. This input is a signal representative of the presence of at least one occupant in the area or room. Upon receiving such signal, the processor 4 will send a signal to the at least one temperature control means 1 for adapting the temperature to the presence temperature setting T PRES . When the occupant leaves the area or room, the means 5 for detecting presence will no longer detect an occupant and will stop sending the signal representative to the presence of at least one occupant to the processor 4.
  • the processor 4 When the processor 4 no longer receives the signal representative of the presence of at least one occupant from the means 5 for detecting presence, the processor 4 will send a signal to the at least one temperature control means 1 for adapting the temperature to the away temperature setting T AWAY .
  • energy consumption can be lowered with respect to the former embodiment, where the HVAC control system 10 is programmed to adapt the temperature to the presence temperature setting T PRES or to the away temperature setting T AWAY at predetermine, programmed time frames.
  • An HVAC control system 10 can even more lower the energy consumption, because it makes it possible to further adapt the presence temperature setting T PRES to at least two different values, i.e. an activity_low temperature setting T ACT_LOW and an activity high temperature setting T ACT_HIGH , the activity_high temperature setting T ACT_HIGH thereby being lower than the activity_low temperature setting T ACT_LOW , but still being higher than the away temperature setting T AWAY . Therefore, the HVAC control system 10 needs to know whether the occupant is active or not. Hence, the HVAC control system 10 furthermore comprises means 6 for tracking activity by the at least one occupant in the at least one area or room.
  • the means 6 for activity tracking may, according to embodiments of the invention, comprise at least on activity tracking sensor such as e.g. an acoustic sensor, a radar senor or other suitable sensors located, for example, in a switch or sensor in a wall or ceiling.
  • the means 6 for activity tracking may further comprise at least one of a mobile device, such as, for example, a mobile phone, a smart watch or an activity tracker such as e.g. a fitness gear, or a camera.
  • the camera may, for example, be activated by a signal from a sensor, such as e.g. a presence detection sensor, present in the area or room.
  • the processor 4 upon receiving a signal indicative of activity in the at least one area or room from the means 6 for tracking activity, the processor 4 will automatically send a signal to the temperature control means 1 to adapt the presence temperature setting T PRES to the activity_high temperature setting T ACT_HIGH . As a response to that signal, the temperature control means 1 will lower the temperature in the at least one area until it reaches the preferred, pre-programmed activity_high temperature setting T ACT_HIGH .
  • the means 6 for tracking activity will continuously be sending information to the processor 4, any small difference or variation inactivity will be sent. In the processor 4, an algorithm will continuously be evaluating the information received from the means 6 for tracking activity.
  • the processor 4 will or will not send a signal to the temperature control means 1 for changing the temperature setting. For example, when evaluation by the algorithm results in low or no activity detection for at least between 10 and 30 minutes, e.g. for at least 15 minutes, it will stop sending signals to the processor 4. Including such time period may be necessary to avoid that the temperature switches too often between T ACT_LOW and T ACT_HIGH . For example, standard settings may be set at 15 minutes, but a user can adapt this to any value that is suitable for a particular situation or this may automatically be adapted by the processor 4 based on detected patterns.
  • the processor 4 will send a signal to the temperature control means 1 for setting the temperature to the preferred, pre-programmed activity_low temperature setting T ACT_LOW , or in other words, it will send a signal to the temperature control means 1 for increasing the temperature to the activity_low temperature setting T ACT_LOW .
  • An example hereof is illustrated in Fig. 3 , which shows an away/present/activity curve 8 (full line) of an HVAC control system 10 according to embodiments of the invention. It is to be understood that this is only an example for illustrating the invention and is not intended to limit the invention in any way.
  • the away/present/activity curve 8 shows in fact temperature settings T AWAY , T PRES , T ACT_LOW and T ACT_HIGH over a whole day are shown. From this curve 8 it can be seen that in the early morning, when everybody is still lying in bed, temperature is set at T AWAY , as is also the case at night, e.g. after 11 p.m..
  • This T AWAY may, according to embodiments of the invention, manually be programmed in the HVAC control system 10, in a way as was described earlier, or may be connected to presence measurements by means 5 for measuring presence of an occupant, as also already described earlier.
  • T PRES may be set at 7 a.m., same time as the alarm clock of the occupant is set. So, at 7 a.m. the processor activates the temperature control means 1 to set the temperature at T PRES .
  • the processor activates the temperature control means 1 to set the temperature at T PRES .
  • means 6 for tracking activity may be provided in every room. However, according to other embodiments, means 6 for tracking activity may, for example, only be provided in the living room, or in the bathroom and the living room, or in any other room that is deemed necessary.
  • means 6 for tracking activity when for example, as mentioned above, means 6 for tracking activity is provided in the bedroom, bathroom, living room and kitchen, once an occupant wakes up and gets out of bed, the means 6 for tracking activity is activated, determines the activity, and sends a signal to the processor 4. As the occupant goes, for example, to the bathroom, activity remains tracked, so the processor sends a signal to the temperature control means to set the temperature at the activity_high temperature setting T ACT_HIGH . Once the occupant is ready for breakfast, he or she goes into the kitchen and sits down at the kitchen table. As described above, when evaluation of the signals sent by the means 6 for tracking activity indicate that there is no for between 10 and 30 minutes, e.g.
  • the processor 4 will send a signal to the temperature control means 1 to set the temperature to the activity _low temperature setting T ACT_LOW .
  • the temperature will increase accordingly, as can be seen in Fig. 3 .
  • the temperature needs to drop down to the away temperature setting T AWAY .
  • This can be obtained by means of the programmed preference in the HVAC control system 10 or can be as a consequence of the fact that evaluation of the signals received from the means 6 for detecting presence indicates that there is nobody present in the building anymore.
  • the away temperature setting T AWAY then stays active until another programmed time frame is reached or until presence is again detected by the means 5 for detecting presence when an occupant is entering the building.
  • the means 6 for tracking activity will also track activity and will send a signal representative to that activity to the processor 4, which at his turn will send a signal to the temperature control means 1 for setting the temperature at the activity_high temperature setting T ACT_HIGH .
  • the signal received by the processor 4 will indicate that there is no longer activity and the temperature will be set to the activity_low temperature setting T ACT_LOW .
  • first activity is measured, so the temperature is set at T ACT_HIGH for a particular amount of time until no activity is measured anymore. Then the temperature is set to T ACT_LOW .
  • the temperature will drop to T AWAY for the night.
  • pre-programmed preference temperature and time frame settings are done by an occupant.
  • means 5 for presence detection is present in the area or room.
  • the means 5 for detection presence of at least one occupant is dominant over the pre-programmation. This means that whenever presence is detected by the means 5 for detecting presence of an occupant, even the time frame for setting T PRES is not yet arrived, a signal will be sent by the processor to the temperature control means so as to set T PRES , and then depending on whether there is activity or not, the processor may further send a signal to the temperature control means for setting the temperature to respectively T ACT_HIGH or T ACTT_LOW .
  • the dashed line indicates the away/presence curve for a prior art HVAC control system.
  • prior art HVAC control systems no distinction can be made between different levels of activity, it is either someone is there or nobody is there. This means that, even when somebody is active for a long period, the temperature will always stay the same as if this person would be on a chair or in a seat for the same period. Because of this, a lot of energy is lost, because during activity the temperature should not be that high.
  • an away/presence/activity curve 8 of an HVAC control system 10 according to embodiments of the invention was described and discussed.
  • Such away/presence/activity curve 8 can have many different settings, either pre-programmed in combination with means 6 for activity tracking or determined by a combination of means 5 for presence detection and means 6 for activity tracking. These away/presence/activity curves with their corresponding settings may, according to embodiments, be stored in a memory 7 of the processor 4. Such stored away/presence/activity curve 8 thus provide historical settings of away temperature settings T AWAY , presence temperature settings T PRES , activity_high temperature settings T ACT_HIGH and activity_low temperature settings T ACT_LOW of the HVAC control system 10 set by a user or determined by the processor 4.
