Description

Simulation air-conditioner temperature signal generator

The utility model relates to a kind of signal generator, refers to a kind of generator that is applicable to the simulated air-conditioner temperature signal of air duct type central air conditioner especially.

Along with the improvement of people's housing condition, the increase of living space, small-sized air duct type central air conditioner has been come into family, and people wish to provide cold wind/hot blast with a central air conditioner for a plurality of rooms, thereby control the temperature in each room.Control the temperature in each room better in order to make the air duct type central air conditioner, some producer develops Intelligent Instrument (Hailin, Beijing equipment company limited), air-conditioning microcomputer controller (Beijing Hui Chang technology ﹠ development Co.), and the end in each air channel, room installs Electric air valve and temperature controller additional.When each indoor temperature that need control the room all reaches setting value, air conditioner intelligent instrument or air-conditioning microcomputer controller are just exported control signal, directly cut off power of compressor or the control signal of compressor is realized close compressor, stop the purpose of freezing or heating by being switched on or switched off indoor set.The shortcoming of this control mode is: when controlled room temperature reaches setting value, just closed compressor, not only influenced other normal function (, having influenced the normal defrosting of air-conditioning) of air-conditioning as because compressor is closed, and because frequent close compressor is serious to compressor damage.

In view of the foregoing, the purpose of this utility model provides a kind of generator of simulating the air-conditioner temperature signal, when the room of required temperature adjustment all reaches design temperature, give analog temperature signal of air-conditioning, inform that just the air-conditioning quilt controlling temperature has reached setting value, the program of air-conditioning after according to original arrival design temperature executed the task, and therefore do not influence other any function of air-conditioning, realizes the seamless link of air conditioner intelligent instrument or air-conditioning microcomputer controller and air-conditioning.

For achieving the above object, the utility model is taked following design proposal: a kind of simulation air-conditioner temperature signal generator, and it is made of switching logic unit and analog temperature signal resistance; One end of switching logic unit links to each other with air-conditioning master control borad sensor terminals, and the other end can link to each other with the original temperature sensor of air-conditioning, also can link to each other with the analog temperature signal resistance; The annexation of switching logic unit is by air conditioner intelligent instrument or the control of air-conditioning microcomputer controller.

The utility model is described in further detail below in conjunction with accompanying drawing.
