Abstract: A climate controller for an automobile, comprising a compressor and a receiver arranged in an engine compartment of the automobile, a condenser located at an outside-air inlet of the engine compartment, an expansion member and an evaporator disposed in a passenger compartment of the automobile, and a closed-loop refrigerant passage connecting the compressor, the condenser, the receiver, the expansion member and the evaporator in sequence for circulating a refrigerant through these components to establish a refrigerating cycle. The climate controller further includes a valve arranged in a part of the closed-loop refrigerant passage extending from the evaporator through the compressor to the condenser. The valve is actuated to intersect a communication of the refrigerant through the part of the passage when an operation affecting temperature of both the compressor and the condenser becomes ineffective, and to allow the communication when the operation becomes effective.

Abstract: A microfluidic pump with thermal control. The microfluidic pump employs a fluid motivation mechanism that moves microscopic fluid volumes through a conduit using thermal vapor bubbles generated using supercritical heating. Aspects of the microfluidic pump include the use of a pump temperature controller that monitors temperatures associated with the microfluidic pump and slows or pauses operation of the microfluidic pump to reduce the rate at which heat is generated allowing additional time for heat to be passively dissipated. Controlling the upper microfluidic pump temperature prevents or reduces overheating of the fluid being pumped that renders the fluid less suitable or unsuitable for its intended purpose or harm to the microfluidic pump. Other aspects of the pump temperature controller include an optional substrate heater that helps raise the fluid temperature to a selected operational range for better performance of the fluid and/or the microfluidic pump.
