A solar powered air conditioning system includes an energy generating loop and a cooling loop. The energy loop includes a tank containing liquid refrigerant, a pump, a heat supply container including a coil, a magnifier lens and a turbine generator. The lens intensifies energy from the sun and directs it to the coil. When the pump is engaged, the refrigerant travels to the heat supply container where the sun heats and changes it from a liquid to a gas. The gas is conducted to the generator producing electricity. The cooling loop includes a shutoff valve, a fan disposed in an environment of interest, a separator, a condenser and an evaporator. In a cooling cycle, the gaseous refrigerant moves from the generator to the separator. The refrigerant is passed to the condenser. The fan directs air to the condenser where the refrigerant absorbs heat to cool the environment of interest.

A miniature thermoelectric cooling device for storing small amounts of thermally unstable substances, like drug vials with insulin for diabetic patients or protein based drugs for thrombolytic therapy, is disclosed. A solar energy collector coupled with a rechargeable battery is provided as the energy source. The miniature cooler is small enough to be belt-carried at all time by a person, whose life or health depends on the drugs. When switched to a heating mode, the thermoelectric device can temporarily elevate the temperature of the drug to a body temperature thus providing comfortable conditions for the injection. A combined solar-and-battery power supply allows keeping an article in the cooler at low temperatures around o'clock at all times during substantially long travels in hot or tropical conditions where even short term exposure to surrounding temperatures can destroy the potency of the drug.

A thermoelectric refrigerator/warmer using no external power, and a refrigerating/warming method are disclosed. A natural energy such as the solar energy is utilized so as to make an external power needless. Thus a thermoelectric device is made to convert the natural energy into electric power based on the difference between the internal and external temperatures, and this electric energy is converted again into a thermal energy by means of a peltier device, thereby varying the internal temperature of the apparatus. An outer part 4 of a thermoelectric device 3 is attached on the side face of the refrigerator/warmer, and an inner part 5 of it is attached on a bottom plate 7 of the refrigerator/warmer. Thus a thermoelectromotive force is generated based on the temperature difference between outside and inside of the refrigerator/warmer. The voltage thus generated is supplied to a peltier device 6 to cool or heat the bottom plate 7. In this manner, the thermoelectric refrigerator/warmer can be operated even without using an external power.

The use of molecular sieve zeolite for the effective utilization of low-grade heat sources such as solar energy. A system includes molecular sieve zeolite and a low pressure polar gaseous fluid adapted to be adsorbed by the zeolite which is in a closed container and circuit which includes a condenser and a gas expansion cooler member. When the container is heated, a gas is given off from the zeolite, cooled in a condenser, and thereafter expanded for cooling purposes. In one embodiment, the cooled gas is received in a further container having the zeolite therein and subsequently, upon cooling of the first container, the gaseous fluid may be returned thereto via again a condenser and gas expansion cooler member to provide further cooling. In another embodiment, zeolite is formed by sintering same to form a pressure resistant divider across the container. One side of the divider is heated to create a temperature gradient across the divider which functions as a heat energized pump for the adsorbed gaseous fluid, a pressure as well as temperature differential developes within the container across the divider whereupon the heated relatively pressurized gas, after giving up some of its energy in a circuit which may include a condenser and gas expansion member, is returned to the container to be again pressurized and heated by the action of the sintered zeolite divider. In a further embodiment, water vapor is adsorbed from a zeolite panel by solar heat during the day and condensed by cooling, and collected in a container, and at night, at a lower relative pressure, it evaporates and is readsorbed by the zeolite panel whereupon ice is formed in the container which collects the water during the day. In another embodiment, a solar heated liquid is circulated in series through heat exchangers in plurality of zeolite filled pressure vessels with intervening cooling coils for the liquid. Nitrogen in one of the vessels is expelled at high pressure through an engine to be adsorbed by a cooler low pressure heated vessel with valving cycling which vessel is at high pressure and which is at low pressure.
