Environmental temperature controlling apparatus

Abstract: PROBLEM TO BE SOLVED: To efficiently gain a sound sleep, namely, a comfortable awakening and a deep sleep by controlling an environmental temperature to match the biological sleep rhythm. SOLUTION: An environmental temperature controlling apparatus 1 includes a depth of sleep measuring means 41 and a temperature controlling means 51. The depth of sleep measuring means 41 has the function of detecting a starting point of sleep T 0 of a human body 9 and the function of measuring the depth of sleep of the human body 9 after the start of sleep and executes the detection of the starting point of sleep T 0 and the measurement of the depth of sleep after the start of sleep. The starting point of sleep T 0 and the depth of sleep are given to the temperature controlling means 51. The temperature controlling means 51 controls the environmental temperature on the basis of a cycle of the depth of sleep by decreasing the environmental temperature monotonously for at least a prescribed period from the starting point of sleep T 0 . The prescribed period is an interval between the starting point of sleep T 0 and the time when the depth of sleep reaches the second extreme value out of the extreme values showing the deep sleep.

Air-conditioning control system

Abstract: In order to provide a suitable environment corresponding to the stress state of room occupants and to the room occupants' purpose of use of the space, a deriving unit (27a) derives multiple heart rate-related parameters of the room occupants (E) on the basis of movement of the room occupants (E), and a determination unit (27b) determines the current stress state of the room occupants (E) on the basis of the heart rate-related parameters. A touch panel (41) receives the purpose for which the room occupants (E) are using the air-conditioned space (S). In response to the received purpose and the heart rate-related parameters, a device control-side CPU (48) selects a heart rate-related parameter that should be changed and controls operation of the air-conditioner (A) such that the selected heart rate-related parameter changes.

Sleep control device and control method therefor

Abstract: A drowsiness level detection section (6) detects a drowsiness level of an individual person. A sleep depth level control section (11) controls the sleep depth of the individual person based on the detected drowsiness level. The sleep depth level control section executes a first sleep control (4, s7), in which the sleep depth level of the individual person is maintained at a predetermined sleep depth level below a maximum sleep depth level (4, s6), if the detected drowsiness level is equal to or below a predetermined threshold.

Apparatus and method for controlling sleep mode of airconditioner

Abstract: An air-conditioner and a method for controlling the same are disclosed. The apparatus and method for controlling the sleep mode of the air-conditioner provides an optimum air-conditioning effect suitable for individual sleep stages in consideration of temperature characteristics of the sleep stages of a sleeping human being, such that it can provide the sleeping human being with an optimum sleep mode. The apparatus includes a room temperature sensor for detecting a room temperature; and a controller for controlling the sleep mode when the sleep mode begins, such that it executes a sleep-entrance stage for a rapid cooling mode during which the room temperature is quickly reduced to a first temperature less than a setup temperature, executes a deep-sleep stage for gradually increasing the room temperature to a second temperature higher than the setup temperature, and executes a wake-up stage for increasing the room temperature to a third temperature higher than the second temperature.

Air-conditioning control system, air conditioning device, air-conditioning control method and air-conditioning control program

Abstract: PROBLEM TO BE SOLVED: To provide an air-conditioning control system and an air conditioning device capable of controlling the air-conditioning suitable for the individual or season. SOLUTION: This air-conditioning control system 1 comprises an air-conditioning control means 2 connected with an air conditioning means 23 for controlling the air conditioning means 23, a sleeping-indoor air-conditioning information memorizing means 4 connected with the air-conditioning control means 2 and memorizing the information on a sleep state of a sleeper 12, and a sleep state control means 5 connected with the sleep-indoor air-conditioning information memorizing means 4 and the air-conditioning control means 2, and outputting a control signal for sleeping to the air-conditioning control means 2 on the basis of the memorized information on sleep state and information on indoor air-conditioning state, and the air-conditioning control means 2 controls the air conditioning means 23 on the basis of the control signal for sleeping.

Automatic temperature adjusting air conditioner based on user deep sleep, air conditioner system and control method

Abstract: The invention provides an automatic temperature adjusting air conditioner based on user deep sleep, an air conditioner system and a control method. Different sleep periods where a human body stays areobtained by collecting and processing the heart rates or respiration rates of a plurality of people; the output refrigerating capacity can be adjusted timely according to the different sleep periodswhere the human body stays; the refrigerating capacity is decreased step by step by adjusting the refrigerating capacity output in the falling asleep period, the rapid eye movement period, a light sleeping period, a sound sleeping period and a sleep sleeping period, and accordingly the indoor temperature is maintained to be in an optimal temperature interval. When there are the multiple people ina room, the control priority of the system is transferred to the person who falls asleep firstly and enters in the deep level sleep firstly, when other people enters in the deeper level sleeping period, and then the control right of the system can be transferred. The heart rate or the respiration rate of the person who possesses the control right of the system joins to adjust the output refrigerating capacity exclusively, and the heart rate or the respiration rate of other people cannot join to adjust the output refrigerating capacity. When there are old people and children in a room, the control priority of the system is transferred to the old people and the children, therefore protection to the human body is enhanced, and the automatic temperature adjusting air conditioner benefits the health of the human body.
