What is the definition of a spot coolers carrier? A spot coolers carrier is a type of refrigeration system that uses a refrigerant to cool down a specific area or spot. It is a separate unit from the main air conditioning system, and is usually used to provide air conditioning relief to a certain area during times when the main system is overwhelmed. Spot coolers are typically portable and can be moved to different locations as needed. They are also relatively easy to install, making them a great option for businesses and homes. Spot coolers come in different sizes and capacities, and can be used for a variety of purposes. For example, they can be used to cool down a kitchen or server room, or even to cool down a small office space. Spot coolers are also ideal for industrial and commercial applications, where the need for cooling is more urgent and frequent. Spot coolers can also be used to cool down a factory or warehouse, and can be used for cooling down storage areas.
