Abstract
The invention relates to a climate control system comprising at least one radiation reducer and a climate control unit for controlling the radiation reducer. Which system further comprises a usage detection system coupled to the climate control unit. It also relates to a method of climate control in a room, using a climate control system comprising at least one radiation reducer, which method comprises the steps of detecting if the room is in use or not, if in use, setting the radiation reducer in a mode of high transmittance, if not in use, setting the radiation reducer in a mode of low transmittance.
Claims10
Climate control system comprising at least one variable radiation reducer capable of variably reducing the transmission of heat radiation through a window, and a climate control unit coupled to and adapted to control the variable radiation reducer, wherein
- the system further comprises a usage detection system for detecting if the room is in use or not, the usage detection system being coupled to the climate control unit, and providing a “non-use signal” when the room is not in use and an “in-use signal” when the room is in use,
- the climate control unit is arranged to set the variable radiation reducer in a non-transparent mode, in response to a “non-use signal” from the usage detection system, whereby a substantial part of the heat radiation is prevented from entering the room, and in that
- the climate control unit is arranged to set the variable radiation reducer in a transparent mode, in response to an “in-use signal” from the usage detection system, whereby a normal daylight level is permitted to pass through the window.
Method of climate control in a room, using a climate control system comprising at least one variable radiation reducer capable of variably reducing the transmission of heat radiation through a window, and a climate control unit coupled to and adapted to control the variable radiation reducer, which method comprises the steps of:
- detecting, with a usage detection system, if the room is in use or not, the usage detection system being coupled to the climate control unit, and providing a “non-use signal” when the room is not in use and an “in-use signal” when the room is in use,
- in response to a “non-use signal” from the usage detection system, controlling the variable radiation reducer to be in a non-transparent mode, by means of the climate control unit, whereby a substantial part of the heat radiation is prevented from entering the room, and
- in response to an “in-use signal” from the usage detection system, controlling the variable radiation reducer to be in a transparent mode, by means of the climate control unit,whereby a normal daylight level is permitted to pass through the window.
Method of climate control in a room, using a climate control system comprising at least one variable radiation reducer capable of variably reducing the transmission of heat radiation through a window, and a climate control unit coupled to and adapted to control the variable radiation reducer, which method comprises the steps of:
- detecting, with a usage detection system, if the room is in use or not, the usage detection system being coupled to the climate control unit, and providing a “non-use signal” when the room is not in use and an “in-use signal” when the room is in use,
- detecting with a temperature sensor if the room should be cooled or heated, the temperature sensor being coupled to the climate control unit, and providing a “cool-signal” when the room should be cooled and a “heat-signal” when the room should be heated,
- in response to an “in-use signal” from the usage detection system and a “cool-signal” from the temperature sensor, controlling the variable radiation reducer to be in a low-transparent mode defined by a low-transmittance parameter, and other parameter control systems in accordance with predefined local control parameters, by means of the climate control unit, whereby at least a part of the heat radiation is prevented from entering the room, unless the low-transmittance parameter is set to a value that corresponds to full transmittance,
- in response to a “non-use signal” from the usage detection system and a “cool-signal” from the temperature sensor, controlling the variable radiation reducer to be in a non-transparent mode, and other parameter control systems in accordance with predefined global control parameters, by means of the climate control unit, whereby a substantial part of the heat radiation is prevented from entering the room,
- in response to an “in-use signal” from the usage detection system and a “heat-signal” from the temperature sensor, controlling the variable radiation reducer to be in a high-transparent mode defined by the high-transmittance parameter, and other parameter control systems in accordance with predefined local control parameters, by means of the climate control unit, whereby at least a part of the heat radiation is allowed to enter the room, and
- in response to a “non-use signal” from the usage detection system and a “heat-signal” from the temperature sensor, controlling the variable radiation reducer to be in a transparent mode, and other parameter control systems in accordance with predefined global control parameters, by means of the climate control unit, whereby a maximum of the heat radiation is allowed to enter the room.
