When buying a cooler for a small room, two things are more important, first, how small is your room, and second, what is the arrangement for ventilation. Because the room is small, the coolant will also give more, but if proper ventilation is not there, the hot air will remain in the room, and in such a situation the coolness of the cooler will not be felt. Nowadays, many types of coolers are available in the market, which is small in size, but you will get other facilities as well.
In the cooler, an ice chamber is now coming up. When it is hot, fill ice with it. Cooler water flows through this chamber through the motor and continuously cool air remains in the room. From turning the cooler on and off via remote, the speed of the fan in it can also be more or less, turning the motor off or on, etc. Honeycomb pads not only last longer than wood wool pads, but they also make the air very cold.
Now there are coolers with technology that work on inverter technology. There is a sensor in it. When the room gets colder, the water motor in it stops and the fan speed decreases. As room temperature rises, first the fan speed increases and later the pump turns on.
