The invention relates to a refrigerating control device for an air conditioner to reduce energy consumption.
An operation principle of a conventional air conditioner is shown in
An inverter air conditioner is thus developed to solve the energy consumption problem. As shown in
An object of the invention is to provide a refrigerating control device which improves energy consumption of inverter air conditioners and conventional air conditioners which have not inverter.
The invention provides a refrigerating control device. The refrigerating control device in accordance with an exemplary embodiment of the invention includes a compressor including a motor, comprising a control circuit connected to the compressor through an electromagnetic switch including a control coil and a contact-switch element including a plurality of input contacts and a plurality of output contacts connected to the compressor and the motor, wherein the control circuit includes a timing circuit connected to the control coil through an interval timing device and a soft start circuit connected to the input contacts.
In another exemplary embodiment, the interval timing device is set to have continuous and alternate operation time and rest time.
In yet another exemplary embodiment, the timing circuit is adjustable.
In another exemplary embodiment, the operation time and the rest time are adjustable.
In yet another exemplary embodiment, the timing circuit and the soft start circuit are modular.
A detailed description is given in the following embodiments with reference to the accompanying drawings.
The invention can be more fully understood by reading the subsequent detailed description and examples with references made to the accompanying drawings, wherein:
The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

Referring to
The timing circuit 50 and the soft start circuit 60 are modular (see
When the refrigerating control circuit 20 is mounted to an air conditioner, the timing circuit 50 turns off the compressor 40 of the air conditioner for a rest time T2 (for example 2 minutes) after the compressor 40 operates for an operation time T1. The timing circuit 50 re-conducts the control coil 31 so that the contact-switch element 32 connects the soft start circuit 60 and the motor of the compressor 40 to start the compressor 40 again, and the compressor 40 continues to operate for another operation time (for example 10 minutes). The timing circuit 50 disconnects the control coil 31 to stop the compressor 40, and the compressor 40 stop operating for another rest time T2 (for example 2 minutes).
The refrigerating control circuit 20 of the invention controls the compressor 40 to operate for an operation time T1 to provide cool air and stop for a rest time T2. The soft start circuit 60 reduces power consumption for restarting the compressor 40. The refrigerating control circuit 20 of the invention improves power consumption of the conventional air conditioner without inverter, and it also effectively improves power consumption of inverter air conditioner. The air conditioner is used so widely, the refrigerating control circuit 20 of the invention can largely reduce power consumption of our society and also reduce cost for building additional power equipment.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
