Portage storage containers including controlled evaporative cooling systems are described herein. In some embodiments, a portable container including an integral controlled evaporative cooling system includes: a storage region, an evaporative region adjacent to the storage region, a desiccant region adjacent to the outside of the container, and an insulation region positioned between the evaporative region and the desiccant region. A vapor conduit with an attached vapor control unit has a first end within the evaporative region and a second end within the desiccant region. In some embodiments, the controlled evaporative cooling systems are positioned in a radial configuration within the portable container.

An absorption refrigerator using a circulation cycle of a regenerator, a condenser, an evaporator, and an absorber includes temperature sensors, a storage unit storing the approximation function for obtaining the second concentration based on second detection results obtained by each of the temperature sensors, a calculation unit to apply the second detection results to the approximation function to obtain the second concentration and a control unit to execute control in accordance with the second concentration. The approximation function is obtained using a response surface method by interpolation or approximation, based on data including first detection results obtained by temperature sensors and first concentrations each corresponding to when each of the first detection results has been obtained.

A system for maintaining the depth of injected vapor in an entrochemical system is disclosed. The vapor transfer pathway terminates in the chamber containing high concentration solution underneath the surface of the solution. In one example the vapor transfer pathway is passively adjustable, using a flotation device to maintain the depth of its end. Another example uses an active, actuated system to maintain the depth of the end of the vapor transfer pathway. The energy for controlling the depth of vapor transfer pathway is minimized by passive methods and derives from the heat of mixing of the vapor and the high concentration solution.

A regulation method for an inverter compressor in a refrigeration system including establishing a working area via limit values for evaporation temperatures, condensation temperatures, compressor speeds, maximum compression ratio, and maximum superheat value, and measuring working values of the compressor in terms of evaporation temperature, condensation temperature, and compression ratio. If the compressor operates outside the established working area, the method includes modifying the working parameters of the compressor by acting on elements to be selected among the compressor speed, the opening angle of the expansion valve, and a combination thereof. If the compressor does not go back to the working area within a certain time, the method includes stopping operation of the compressor and triggering an alarm.

Systems and methods for compressor-assisted sorption rate. A sorption system includes a sorber that absorbs and desorbs a refrigerant gas, such as ammonia, onto and from a coordinative complex compound. The system includes an evaporator, a condenser, and a compressor. The temperature and pressure of the gas within the sorber are monitored and the compressor is controlled to adjust the pressure to increase the absorption and desorption rates and enhance the thermal cycle speed of the sorption system for applications such as laser systems requiring rapid, periodic cooling.

A temperature controller for a sorption system having an evaporator to produce a gas, a sorber containing a sorption material to sorb the gas during a sorption phase, a flow channel extending between the evaporator and sorber to provide a gas pathway connecting them, a valve to control the rate of gas flow in the flow channel, and a temperature sensor positioned to measure the temperature of an evaporator surface or the air adjacent thereto indicative of an evaporator surface temperature, and generate a temperature signal. The controller includes an inflatable member having first and second inflation states, and a control unit configured to evaluate the temperature signal and in response control the state of inflation of the inflatable member and thereby the operation of the valve to control the rate of gas flow between the evaporator and sorber through the gas pathway.
