Embodiment Construction

[0007] The drawing shows a schematic diagram of an indoor climate control system, in which a climate control device 1 has a control line 2 which is usually connected to a climate-influenced impedance device 3 . The weather-affected impedance device 3 may comprise, for example, a temperature sensor (such as a thermistor), an air humidity (RH) sensor (which may be capacitive and / or resistive), and a carbon dioxide (CO 2 ) One or more of the sensors. The switching device 4 is arranged to disconnect the weather-affected impedance device 3 from the control line 2 under the influence of the third output 5 of the control unit 6 , replacing it with the replacement device 7 . Thereby, as described below, an impedance controlled by the first output 8 of the control unit 6 is provided. Normally, therefore, the climate control device 1 is coupled to the weather-influenced impedance device 3 , but can be disconnected by means of the invention, whereby instead an alternative device 7 is co...

Abstract

An indoor climate control system in which a climate controlling equipment (1) has a control line (2) arranged to be connected to climate influenced impedance means (3), switching means (4) being arranged to disconnect the climate influenced impedance means from the control line under influence from a third output (5) of a control unit (6) and to instead connect substituting means (7) providing an impedance controlled by a first output (8) of the control unit, the control unit having polarity probing means (13) arranged to obtain an indication whether a connection of the substituting means to the control line results in a voltage with a positive or negative polarity, the connection of the substituting means being made in dependence on that indication and under influence of a second output (14) of the control unit. According to the invention, the substituting means comprise a series connection of two equivalent impedance networks (15, 16) provided each one with by-pass switching means (17, 18) for a plurality of impedance means (19, 20) that have series connected semiconductor switching means (21, 22) arranged in opposite directions and controlled by the first output (8) of the control unit, the by-pass switching means being arranged to be alternatively activated by the second output (14) of the control unit.

Description

technical field [0001] The invention relates to an indoor climate control system in which a climate control device has a control line arranged to be connected to a weather-affected impedance device. Background technique [0002] Indoor climate control systems of the type described above are present in many facilities and represent a significant energy drain. For the average user, and for the global community in particular, less energy consumption is desired. While new systems can achieve energy savings while maintaining climate comfort levels, only a small fraction of currently used facilities are likely to be replaced in the not-too-distant future. Instead of accepting the cost of a new facility, the user may choose less comfort in order to reduce energy consumption. A huge market can be found for adapters (control systems) that save energy without losing climatic comfort. According to this solution described in WO2013070159, the relay means are arranged to disconnect th...
