IoT Based Smart Cupboard Design

During the rainy season, the clothes can dry for 1 day or more. Often times when on the way home from work or school it is trapped in rain so that the clothes used are little damp, because the clothes are still used for tomorrow so the clothes are not possible to wash and can dry overnight. easy to open or break into by anyone, given the habit of people used to storing valuables in the cupboard, an extra security system is needed. Then a IOT-Based Smart Cupboard Design is made which aims to improve the function of a conventional wardrobe to be multifunctional, which is equipped with a damp clothes dryer feature and is equipped with a Fingerprint sensor which can only be accessed by the owner to open the wardrobe. to be equipped with a Fingerprint, which functions as extra security in opening cabinets where valuables are usually found. Also equipped with a fan and heater incubator functions in drying damp clothes. This tool is equipped with an IoT which functions as an On Off control for the fan and an incubator heater in heating damp clothes.

Energy Recovery from an Industrial Clothes Dryer Using a Condensing Heat Exchanger

The aim of this project was to design a condensing heat exchanger to recover waste heat from an industrial clothes dryer. Industrial cloth dryers are inefficient in their use of energy because almost all of the energy input in the dryer is wasted in the atmosphere, and thus there is great potential for heat recovery. This energy can be used to preheat the incoming cold water, and the conventional heater can then heat the water to a final temperature. The warm moist air from the dryer carries both sensible and latent heat, and in order to design this heat recovery condensing heat exchanger, the heat transfer by both mass and sensible heat has to be accounted for. The basis of this heat and mass transfer problem was the energy balance at the interface, and separate models for the calculation of latent and sensible heat transfer were used. The mass transfer coefficients were obtained from an analogy with heat transfer, and the unknown interface temperature was solved for iteratively. The data for this design was collected from a 20 kW dryer, and the heat recovery from that dryer was observed to be about 17.3%. This heat recovery condensing heat exchanger efficiency can be enhanced by the addition of more coils to the heat exchanger. An improvement in the overall results can be expected if a practical study is done on the condensation heat exchanger for an industrial cloth dryer.
