A temperature controlled storage device for storing food and beverages includes a shell, which defines an interior space and is resiliently flexible. The shell comprises an inner layer and an outer layer that define an internal space, to which addition of air selectively inflates the shell from a collapsed configuration to a semirigid configuration. A top of the shell is reversibly couplable to opposing sides and a front of the shell so that the top is hingable relative to a back of the shell to allow access to the interior space. A closure that extends between the top of the shell and both the opposing sides and the front of the shell is positioned to selectively couple the top to the shell. A temperature control module that is coupled to and positioned in the shell selectively warms and cools the interior space and contents thereof.

Embodiments of the present invention reduce the amount of energy required to operate air-conditioners and refrigerators by providing a vapor-compression system that harnesses a low- or no-cost source of energy, namely, heat, and uses the harnessed heat to power a new kind of compressor, called a “burst compressor” and a new kind of pump, called a “vapor pump.” The heat-driven burst compressor pressurizes the refrigerant, while also providing “push and pull” vapor refrigerant to the vapor pump. The vapor pump, actuated by the high pressure refrigerant in gaseous form provided by the burst compressor, is configured to pump a combination of gaseous, vaporous and liquid refrigerant out of the receiver tank and inject that low pressure refrigerant mix into the burst compressor, where it is heated to change the state of the refrigerant to a heated, pressurized gas. Then the heated, pressurized gas is released in bursts into the other components of the vapor compression cycle. Thus, embodiments of the present invention use heat to provide cold. Because of this arrangement, vapor-compression systems constructed and arranged to operate according to embodiments of the present invention are able to provide air-conditioning and/or refrigeration much more efficiently and with much less expense than traditional vapor compression systems for air-conditioning and refrigeration.

A refrigeration unit includes an evaporator circulating a flow of refrigerant therethrough to cool a flow of compartment air flowing over the evaporator, a compressor in fluid communication with the evaporator to compress the flow of refrigerant, an engine operably connected to the compressor to drive operation of the compressor, an expansion device in fluid communication with the flow of refrigerant, and a controller operably connected to at least the engine and the expansion device. The controller is configured to determine an available power to drive the compressor, determine a compressor discharge pressure upper limit based on the available power, compare the compressor discharge pressure upper limit to a requested compressor discharge pressure, and initiate adjustment of the expansion device such that an actual compressor discharge pressure is the lesser of the requested compressor discharge pressure or the compressor discharge pressure upper limit.
