Description

Physiological rhythm adaptive heating and ventilation air conditioning system Field of invention

The invention relates to a circadian rhythm adaptive heating and ventilation air conditioning (HVAC) system, in particular to a method according to a large amount of control data and real-time environmental data submitted by a user voluntarily, statistically analyzing a physiological rhythm of a living body, and adjusting an operation effect according to the physiological rhythm, A system centered on HVAC components.

Background technique

The traditional HVAC operates under the control of the user with fixed power (heating on sunny days, cold weather, cold weather) or fixed state (window on/off), or a fixed temperature range (the temperature sensor of the air conditioner has a certain error). However, the comfortable environment of biological sensation is not static. The most common trouble: use air conditioning and cooling in the summer night, often wake up in the morning, and then increase the air conditioning cooling temperature; sleep in the winter night blanket, often wake up in the morning, and then change the cotton quilt to rest. This is because the body temperature of a person, and the physiological activities on which it is based, will periodically change according to a certain rhythm. And if HVAC can adapt to the circadian rhythm of the organism, it can not only improve the comfort of the organism, improve the sleep/work/life quality, but also improve the energy efficiency of the heating/cooling system and avoid unnecessary waste.

U.S. Patent No. 6,536,675, issued to theU.S. Patent No. 6,536,675, which is incorporated herein by reference, discloses a method for temperature control based on occupancy of a room, and includes a step of temperature control based on the circadian rhythm of the resident during sleep. However, the time-dependent periodic phenomena in organisms are still based on experience and can be disturbed by the environment, such as exposure to blue-rich light sources (such as LEDs), which can lead to a decrease in melatonin. In short, the patent's understanding of the circadian rhythm of the organism is too simple. At present, no basic law has been found, which can improve comfort and energy efficiency when the household cools down by 2 °F during sleep.

U.S. Patent Application Serial No. 14/956,082, the disclosure of which is incorporated herein by reference to the entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all However, due to various disturbances of the environment to the circadian rhythm, when the user repeats the comfort feedback, the invention lacks an effective method of distinguishing it as "regular" or "disturbing", and instead assumes that it is "regular" temperature control, but instead Increase unnecessary user feedback burden.

Summary of invention

This circadian adaptive HAVC system clearly includes an HVAC function module that implements one or more functions of heating/ventilation/air conditioning. In order to collect and transmit data, wireless access is required. Multiple HAVC components can be independent of each other, each connected to the Internet.

At the beginning of the establishment of the entire circadian adaptive HAVC system, since there is no user feedback data on the circadian rhythm, the default control mode (factory initial setting) is blank. As the data becomes more plentiful, the new factory-made HAVC component control system, the built-in default control mode (factory initial setting) will contain circadian rhythms based on statistical analysis and adjusted according to user attributes. For example, the temperature range in which women feel comfortable is usually 2 °C higher than men. This default control mode can be updated online. In order to protect user privacy, the user must be licensed regardless of the data submitted or the update control mode.

Mainstream wireless access technologies (such as WiFi, LiFi, etc.) are significantly different from conventional wireless remote communication technologies (infrared, Bluetooth). Therefore, according to all embodiments of the present invention, including:

Computation module, including CPU/memory, etc., for data processing

Remote control communication module for communicating with the remote control and transmitting remote control commands

· Wireless communication module to transfer data and software to the data center by connecting wireless access points

HVAC function module for one or more functions of heating/ventilation/air conditioning

· Organism identification module for identifying different organisms, automatically switching to user personalization in different work areas between one or more HVAC components according to basic attributes of the organism (such as gender) and biological circadian rhythms Customized work results

However, it is to be understood that the invention is not intended to be limited or limited by the scope of the invention, and the invention disclosed herein The skilled artisan includes significant improvements and modifications thereto.

Thus, embodiments are examples or implementations of the invention, not the only implementation. The appearances of "one embodiment", "an embodiment" or "an embodiment" are not necessarily referring to the same embodiment. Although various features of the invention may be described in the context of a single embodiment, the features may be provided separately or in any suitable combination. Conversely, although the invention may be described herein in the context of a separate embodiment, the invention may be practiced in a single embodiment or any combination of the embodiments.

It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the related art and the present disclosure, and will not be construed as idealized or excessive. Formal meaning, unless explicitly defined in this article.

Many large buildings have air conditioning zones, but their adjustment panels are usually fixed to one side of the interior wall. In addition, according to the statistical results, the temperature and airflow of different genders and ethnic groups have a certain regularity. If you have to adjust the user repeatedly every time, the comfort will not be discussed. If different working areas between one and more HVAC components achieve the same effect according to the basic attributes and feedback data of different organisms, and this process is basically automatic (considering environmental disturbances), not only can the complexity be reduced (relative to the user), it is easy to find a precise combination of comfort parameters, and can improve energy efficiency and reduce emissions (because the disturbance of the system is reduced by repeated adjustment).

Typical application scenarios include, but are not limited to:

· The same organism, switching between different working areas between the same HVAC components, such as between the office/conference room, automatically dynamically adjusted according to the individual circadian rhythm;

· The same organism, switching between different working areas between different HVAC components, such as between home/office, automatically dynamically adjusted according to the individual's circadian rhythm;

The biometric individual identification module included in the present invention may be a simple radio frequency identification (RFID) or a software or service using off-the-shelf hardware (such as a smart phone background service).
