Float Switches in Portable Air Conditioners
Air Conditioners remove heat and moisture from an occupied space thereby improving the comfort of the occupants. The air conditioning of a room is usually planned during construction of the space, so that the drain pipes and other gas pipes in the case of split air conditioners are laid into the walls before plastering is done, for aesthetic reasons. For people who have not planned for air conditioning in a space, portable units are available, and these are easily transported wherever required.
Regular air conditioners cool an area by first removing the humidity in the room and ejecting it the water via the drain pipe. Portable ACs also need to do this, but the water needs to be filled into a tank as it cannot be expelled from the system. When the water in the tank get filled up, it needs to be evacuated manually. This is where reed switches help sense the level of water in the tank. Reed Switch based float switches are fitted in these tanks to trigger an audio-visual alarm to the occupants of the room asking them to drain the tank without which further cooling will not be possible.
Applications are classified as Position Sensing, Pulse Counting, Electromagnetic or Relay, Temperature Sensing or Magnet Biasing types. This application is classified as follows and the link gives more information on best practices to help select the most suitable AT band and matching magnet.
The Reed Switches and Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and our intention is to ensure end product durability and life. Although we wouldn’t want to restrict any of our products for use in only certain applications, the recommended products for use in this application are listed below.
