Abstract

A control method includes pre-setting a PMV index range for an internal space in which a fan and an air conditioner is mounted and measuring a PMV value of the internal space; comparing the PMV value of the internal space with the PMV index range; and increasing a rotational speed of the fan when the PMV value of the internal space is greater than the PMV value of the PMV index region, and decreasing the rotational speed of the fan when the PMV value of the internal space is less than the PMV value of the PMV index region.

Claims

1. A control method for an energy smart fan, comprising:

pre-setting a PMV index range for an internal space in which a fan and an air conditioner is mounted and measuring a PMV value of the internal space;

comparing the PMV value of the internal space with the PMV index range; and

increasing a rotational speed of the fan when the PMV value of the internal space is greater than the PMV value of the PMV index range, and decreasing the rotational speed of the fan when the PMV value of the internal space is less than the PMV value of the PMV index range.

2. The control method as claimed in claim 1, wherein the fan has multiple control stages comprising a maximal speed stage and minimal speed stage, and a warning of temperature regulation is displayed on a remote controller when the fan is at the maximal speed stage or the minimal speed stage.

3. The control method as claimed in claim 1, wherein the rotational speed of the fan is controlled by a signal transmitted from an information appliance to the fan via a wireless device, a recognition module, a signal control module and a signal converting module.

4. The control method as claimed in claim 1, wherein the PMV index rage is from −

0.5 to +0.5.

5. The control method as claimed in claim 2, wherein the PMV index rage is from −

0.5 to +0.5.

6. The control method as claimed in claim 3, wherein the PMV index rage is from −

0.5 to +0.5.

7. The control method as claimed in claim 1, wherein the MPV index range is changed by an overcooling/overheating device.

8. A control system for an energy smart fan, comprising:

a PMV control system configured to set PMV index range, wherein the PMV index range is set to an intermediate range in which human feel comfortable;

an environment detecting device measuring a PMV value of an internal space in which at least one fan and an air conditioner is mounted; and

a comparing device connected to the fan and regulating a rotational speed of the fan according to comparison of the PMV value with the PMV index range.

9. The control system as claimed in claim 8, wherein the fan has multiple control stages comprising a maximal speed stage and minimal speed stage, and a warning of temperature regulation is displayed on a remote controller when the fan is at the maximal speed stage or the minimal speed stage.

10. The control system as claimed in claim 8, wherein the rotational speed of the fan is controlled by a signal transmitted from an information appliance to the fan via a wireless device, a recognition module, a signal control module and a signal converting module.

11. The control system as claimed in claim 8, wherein the PMV index rage is from −

0.5 to +0.5.

12. The control system as claimed in claim 8, wherein the MPV index range is changed by an overcooling/overheating device.
