Where Is the Relay For the Cooling Fan?

Cooling fans are installed in our house and when we turn them on it helps us to feel cooler. But there are some places where cooling fans are not installed. We have not seen any fans in the bathroom and the kitchen, but we don’t know the reason behind that.

We are sure that the main reason is the lack of knowledge and awareness, but there are some other reasons too.

A bathroom is a place where there are no windows and hence cooling fans aren’t required. However, if we have a window, then we can install a cooling fan and make our bathroom a comfortable place.

But there is a strange thing, there are some houses where cooling fans are not installed, but there is a large window in the kitchen. Why is this so?

Is there a reason?

Well, there is a reason behind this but I am not sure that you will like the answer. The reason is that a kitchen is a place where we prepare food for our family. So, we don’t have time to cool down as it takes a long time to prepare food.

Even though we don’t need cooling fans in the kitchen, but still they are installed there. Now, this is the point where I am going to explain the reason behind this.

The kitchen is an open space and we cook food in the kitchen, but the temperature of the room increases due to the amount of cooking. So, it is very important to keep the temperature of the kitchen low.

This is why cooling fans are installed in the kitchen. They work like an air conditioners.

Are you tired of hearing the same old excuse from your friends and relatives regarding the lack of cooling fans in the kitchen? Well, now I am sure that you will be ready to buy a cooling fan and install it in your kitchen.

How Does Fan Relay Work?

We know that in order to maintain a comfortable temperature in our room, we need to use a fan to blow hot air toward the ceiling and the cooler air goes down to the floor. This is how a fan works but in order to understand how it works, we need to know about fan relays.

How Does a Fan Relay Work?

A fan relay is a device that helps the fan to switch on and off automatically. The reason behind using a fan relay is to save electricity. When you switch on a fan, it takes some time for the fan to blow air. So, you can save electricity by switching on the fan relay.

Types of Fan Relays

There are two types of fan relays; mechanical and electronic. The mechanical fan relay is the one that turns the fan on and off manually. Whereas, the electronic fan relay is the one that turns the fan on and off automatically.

Fan Relays

A mechanical fan relay is used to control the fans that are connected to the mains. These relays are also called wall switches. These relays are usually placed near the wall sockets and control the fan.

An electronic fan relay is one that controls the fans that are connected to the mains. These relays are also called wall switches. These relays are usually placed near the wall sockets and control the fan.

The electronic fan relay is usually installed near the outlet box and has an electronic component that detects the voltage and turns the fan on and off when it is required.

Both the relays work in a similar way and the only difference is that the mechanical fan relay has a spring and when the spring is released, it turns the fan off. Whereas, the electronic fan relay does not have a spring and turns the fan off when the voltage is not detected.

If you are planning to install a fan in your room then you must install a fan relay. Because the fan relay saves you from a lot of trouble and also it helps in saving electricity. So, I have explained the differences between mechanical and electronic fan relays and their working mechanism.
