AUTOMATIC TEMPERATURE CONTROLLED FAN

AUTOMATIC TEMPERATURE-CONTROLLED FAN

ABSTRACT:

The programmed temperature controlled fan is an undertaking to control the speed of the fan with the examination of room temperature. This is a Home Appliance venture. By this venture, we can’t change the speed of the fan regularly.

The field of mechanical designing has a topic word called “CHANGE” as its spine. The new innovative headways and the necessities of individuals have influenced us to consider this task. Our task is lady wander into the field of air temperature controlling and furthermore manages human solace.

Human solace conditions manage the states of condition around you, viz HOT and COLD. Our undertaking is an original plan to control the fan. This unit would be a monetary utility at all spots to give comfort conditions to the general population.

PRESENTATION:

This is a task through which the speed of a fan can be straightly controlled naturally, contingent upon the room temperature. The circuit is exceedingly productive as it utilizes thyristors for control. On the other hand, a similar circuit can be utilized for programmed temperature controlled AC control.

APPLICATION:

1. HOUSING

2. PLACE OF EMPLOYMENT

3. EATING AND AMUSEMENT PLACE

4. PRINTING PLANTS

5. PRECISION PLANTS

6. TEXTILES

7. STEEL MANUFACTURE

8. PHARMACEUTICALS

9. PHOTOGRAPHIC PRODUCTS

10. LIBRARIES AND MUSEUMS

ADVANTAGES:

 No need of Human Power to fluctuate the speed of the Fan

 Can utilize the Fan with redress speed

 The control circuit is completely secluded from a control circuit, accordingly giving included security

 The speed of the Fan can be balanced for any Room Temperature by altering pot meters VR1 and VR2 fittingly

 Simple in development

 This framework is quiet in a task

 It is convenient, so it can be exchanged effectively from one place to other places

 Power utilization is less

 Maintenance cost is low

 Small size and ease

 Fast reaction over tight temperature run.

 Good affectability in the NTC area

 Cold work remuneration not required because of reliance on protection on supreme temperature.

 Contact and lead protection issues not experienced because of substantial Rth (protection).

DISADVANTAGES:

It doesn’t filter air

There might change of loop once in a year

Nonlinearity in protection Vs Temperature qualities.

Unacceptable for wide temperature go.

The low excitation current to stay away from self-warming.

Need of protected electrical cables, channels, and so forth, because of high protection.
