Abstract: The present invention relates an automatic adjusting control system which is able to automatically adjust an operation setting value thereof according to the air-conditioning environmental conditions and the changes of load or the requirements of users. The control system mainly includes a plurality of air-conditioners, a plurality of sensors, a central control unit which is able to compare the operation setting value with values detected by each of the sensors to produce a mating signal, and a plurality of control boxes being able to control the operation of each of the air-conditioners according to the mating signal supplied from the central control unit so as to adjust the air-conditioning effect and to save energy.

Abstract: An air conditioning device has a controller, a fan motor, a by-path strangler, and a heat exchange pipe. The fan motor is disposed in front of the heat exchange pipe. The by-path strangler is disposed between the fan motor and the heat exchange pipe. The controller controls the by-path strangler. The controller has a central processing unit, an output control unit, a detect unit, and a sensor. The sensor senses an environmental detect value to the detect unit. The detect unit outputs the environmental detect value to the central processing unit. The central processing unit outputs a signal to the output control unit. The output control unit has a plurality of output junctions connected to a loading unit. The loading unit has a drive motor and two electric valves.

Abstract: The present invention relates to a refrigerating air-conditioning system which can be used to reduce and reuse waste energy. The system includes a fan motor which is used to supply a variable wind rate to an intermediate heat exchanger. In such a manner, when the cold making requirement is greater than the heat making requirement, the intermediate heat exchanger functions as an auxiliary condenser so as to variably change the waste heat needed to be drained from the refrigerating air-conditioning system. When the heat making requirement is greater than the cold making requirement, the intermediate heat exchanger functions as an evaporator so as to variably change the heat needed to be absorbed by the refrigerating air-conditioning system. When the cold and heat making requirements exist synchronously, the intermediate heat exchanger functions as an auxiliary condenser so as to change the waste heat needed to be drained from the refrigerating air-conditioning system.
