Cooling-only room air conditioners are marketed in various Btu/h capacities.
Step-by-step explanation:
Cooling-only room air conditioners are marketed in various British thermal units per hour (Btu/h) capacities. These capacities indicate the cooling capacity of the air conditioner, meaning how much heat it can remove from the air per hour. For example, a cooling-only room air conditioner might be marketed as a 10,000 Btu/h unit or a 15,000 Btu/h unit.
