摘要： Climate control devices and methods are disclosed. One climate control device includes a housing, an evaporative medium port, a liquid level sensor, and a controller. The controller is configured to determine a change in the level of liquid in the housing, calculate an efficiency of an evaporative medium received by the evaporative medium port based on the change in the level of liquid, and provide an evaporative medium efficiency indication when the efficiency of the evaporative medium falls below a predetermined value. Another climate control device includes a housing, an evaporative medium port, a pump, a first conduit, and a controller. The controller configured to determine an evaporation rate of an evaporative medium received by the evaporative medium port, and operate the pump to pump liquid through the first conduit to the evaporative medium port at varying liquid flow rates dependent on the evaporation rate of the evaporative medium.

摘要： Climate control devices and methods are disclosed. A climate control device includes a housing, an ultrasonic emitter, an ultrasonic receiver, and a controller. The housing defines a receptacle for receiving liquid. The ultrasonic emitter is positioned to emit an ultrasonic wave toward a surface of the liquid received in the receptacle. The ultrasonic receiver is positioned to receive the ultrasonic wave after the ultrasonic wave reflects off of the surface of the liquid. The controller is configured to provide a liquid level indication based on the ultrasonic wave received by the ultrasonic receiver. A climate control method includes receiving liquid in the receptacle, emitting an ultrasonic wave toward a surface of the liquid in the receptacle, receiving at least a portion of the ultrasonic wave after the ultrasonic wave reflects off of the surface of the liquid, and providing a liquid level indication based on the received ultrasonic wave.
