Abstract: A method of preventing water carryover to an object cooled by an air flow from a cooling device includes receiving at least one representation of a relative humidity of the air flow, and preventing water carryover to the object by adjusting at least one cooling parameter of the cooling device based, at least in part, on the relative humidity. Further embodiments and cooling systems are also disclosed.

Abstract: A method of providing variable cooling includes operating a cooling element to cool an air flow by a first cooling capacity, operating a heating element to heat the air flow by a first heating capacity that adjusts the first cooling capacity towards a first desired total cooling capacity, determining a second desired total cooling capacity, controlling the cooling element to cool the air flow by a second cooling capacity that is greater than the second desired total cooling capacity, and controlling the heating element to heat the air flow by a second heating capacity that adjusts the second cooling capacity towards the second desired total cooling capacity. Further embodiments and cooling systems are also disclosed.

Abstract: A method of cooling including providing a fluid flow at a predetermined temperature, and adjusting at least one cooling parameter of at least one cooling device to maintain the predetermined temperature of the fluid flow when a desired mass flow of the fluid flow changes. A cooling system and further embodiments are also disclosed.

Abstract: A method of controlling an output temperature of an air conditioning unit including acts of drawing an air flow into the unit to create an air flow through the unit, directing the air flow across a plurality of heating elements, including a first heating element and a second heating element, generating a first pulse width modulated (PWM) control signal, applying the first PWM control signal to a first contactor to control the first heating element to heat the-air flow, generating a second pulse width modulated control signal that is phase shifted from the first PWM control signal, and applying the second PWM control signal to a second contactor to control the second heating element to heat the air flow. Cooling systems and further embodiments are also disclosed.
