摘要： In the method of the present invention, electrostatic fields are used to induce heat pumping action of a working fluid. A plurality of heat pumps with no moving parts are used. The operation of the one pump enhances the operation of the next. The method of the present invention is conducive to devices of a wide range of scales. Furthermore, operation at partial power levels is practicable, and precise control of temperature possible. Control is further enhanced by the addition or removal of further units to the system. Reliability should be enhanced, and peak power demands reduced. Wide selection of possible working fluids allows for the elimination of environmentally harmful halocarbons. In one embodiment of the present invention, chemical working fluids are eliminated entirely. In another embodiment, supercooled fluids such as liquid helium may be used while eliminating the wastage commonly encountered using such fluids.

摘要： The present invention introduces a heat engine, or a heat pump, in which the working medium used is subjected alternatively to solidification and melting operations. A working medium so used is referred to as an S/L type working medium. In a new heat engine, an S/L type working medium is subjected to cyclic operations, each cycle comprises of a high temperature melting step conducted under a first pressure, and a low temperature solidification step conducted under a second pressure. In a new heat pump, each cycle comprises of a high temperature solidification step conducted under a first pressure and a low temperature melting step conducted under a second pressure. When a non-aqueous medium is used, the first pressure and the second pressure are a relatively high pressure and a relatively low pressure, respectively. When an aqueous medium is used the two pressures are a relatively low pressure and a relatively high pressure, respectively. it is noted that the operation of a heat pump is the reverse operation of a heat engine.

摘要： A refrigerant leakage detection sensor for a heat pump includes a sensor casing, a circuit board enclosed by the sensor casing, and a gas sensor mounted on the circuit board. The gas sensor has a housing, a refrigerant reception area at an end of the housing allowing gaseous refrigerant to enter the housing, and a sensing element in the housing. The housing protrudes through an opening in the sensor casing so that the refrigerant reception area is arranged outside the sensor casing and the sensing element is positioned inside the sensor casing.

摘要： 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.
