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 refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

A diffusion absorption refrigeration apparatus includes a bubble pump; a gas-liquid separator; a condenser; a gas branch pipe; an evaporator; an absorber; a gas heat exchanger; a storage tank; and a solution heat exchanger, in which a single material of trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)) and 2,3,3,3-tetrafluoropropene (R-1234yf), which have a low global warming potential (GWP), or a mixture thereof at a predetermined ratio is used as a refrigerant. Accordingly, the stability is high and a low GWP can be achieved.

A leakage sensor for a heating unit of an absorption cooling device for a recreational vehicle, a heating unit, an absorption cooling device, a vehicle and a method for operating an absorption cooling device are provided. The leakage sensor uses sensor pins to detect cooling fluid leaking from the boiler of the heating unit of the absorption cooling device into the boiler insulation by measuring the electrical resistance and/or conductivity within the boiler insulation.

A cooling system is provided and includes a compressor, an expansion valve, a gas cooler through which a refrigerant received from the compressor passes toward the expansion valve in a supercritical state, an evaporator interposed between the expansion valve and the compressor and a vapor sorption subcooling system. The vapor sorption subcooling system includes a desorber disposed to remove heat from refrigerant flowing from the gas cooler toward the expansion valve.

Some aspects of the invention provide an air cooling system. The air cooling system may include a solar energy gathering component that drives a cooling system. The air cooling system may include an absorption cooling system or a thermoelectric cooling system. The cooling system may include a solar collector matched with an air venting system. The cooling unit may hang on the inside of a window or on another vertical surface and utilize the heat and/or radiation from the sun to activate a cooling mechanism that, in turn, provides cooling via the cooling system.
