Question
Background The ceramic space heater (Figure 1) has two heat settings, low and high. As a result, we are either baking or freezing in our 10ft x 14ft apartment bedroom and its time to do something about it. We will begin by developing a model of the system; later on, we will use this model to develop a solution. system; ater on, we will use this model to Figure 1: Ceramic Space Heater Objective We will eventually design a controller for the ceramic heater that regulates the flow of power to achieve a desired room temperature. Our immediate objective is to develop a lumped parameter system model which can be used later in designing the control system. A schematic of the system is shown in Figure 2 below.Explanation / Answer
Its great portable and energy efficient heater when you want to save floor space and have an effective heater for your home. It is easy to use and requires no setup or assembly so that you can use it straight away.
A button at the top of the heater allows you to turn it on with a simple press and a digital display allows you to see at a glance what temperature the unit is running at. You can also choose from low or high-speed settings to suit your needs and room size.
To ensure that the heater disperses heat evenly around the room, it features an oscillating function. This allows the heater to send the warmth in all directions and not just straight ahead. You can turn the oscillating feature off if you like. Because this is a taller unit, you can also benefit from a taller stream of heat coming from the heater, which gives the feeling that the room is warming up even better.
For safety, this heater has overheat protection integrated into the design to allow it to cool if it becomes too warm or if the air around is too hot.
Tower heaters typically provide an oscillating motion that pushes heat around to different parts of a room, which helps them spread heat more effectively. You would place most tower heaters on the floor, but the Sunpentown unit is a small tower heater designed for countertop use so that it can blow its heat directly on your upper body. (You could also put one on the floor under a table to warm your legs.) It comes with an auto-shutoff that helps if you forget to turn it off and leave the room, and a safety shutoff if it is tipped over. It is also cool enough to touch even when operating on high. It can run at 600 watts, 1200 watts, or in fan-only mode, which makes it useful in summer as well as winter. The Sunpentown mini tower heater is also a very well made personal space heater and is one of the quietest available – so quiet you may wonder if it’s even on. It comes with a 1-year warranty and gets very good customer reviews, although you really need to be aware of how small it is. Unlike other tower heaters that can be 32, 40, even 50 inches high, this little heater is just over a foot in height, at 6 by 4-1/2 by 13-3/4 inches. It can do a decent job of heating a small room – say under 10×10 feet – but don’t get this model if you want to heat a larger space, especially in a cold climate or in a room that is poorly insulated.
