A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.

An indoor cooling system kit can include aluminum beverage cans, flexible hoses, a fan, and instructions for forming the indoor cooling system. Further kit materials can include containers, dehumidifying material, a filter, and further instructions. A method of cooling an indoor region can include cutting tops and bottoms away from aluminum beverage cans, coupling the cans together in series to form two elongated airflow passages, coupling a flexible hose to open ends of both airflow passages, adjusting the hose so that both airflow passages and hose form a U-shaped airflow passage, forming a hole in the ground beneath the indoor region, inserting the U-shaped airflow passage into the hole with its inlet and outlet elevated out of the hole into the indoor region, and operating a fan to force air through the inlet. The air is cooled geothermally as it travels through the overall U-shaped airflow passage.

A system cools a space toward target conditions using an air conditioning process based on a bank of different cooling device types. Some device types consume relatively less energy and are suitable for mild environmental conditions, others consume more energy and are needed for extreme conditions, while others may fill a middle ground. To help save energy, the system alters the air conditioning process by selecting one or a mix of cooling device types expected to be sufficient for current conditions. Current conditions corresponds to a supply air position on a psychrometric chart. Selection of the appropriate cooling device type(s) is made according to the location of the supply air position relative to a dew point, which is determined from the target conditions set by a user.
