Solar energy collector assembly - consists of heat and age resistant channels in honeycomb construction to attract solar irradiation

The channels are parallel and made with the same transparent material and of the same thickness (2) and can be square, rectangular or polygonal section tubes. The heat and light irradiation is absorbed by the end surface and the structure is non combustible and does not comprise individual tubular channels. A porous heat resistant baseplate (5) is used at the end of the honeycomb stack to collect the irradiated heat and light after it enters the channels and it then simultaneously releases the light through its pores. Behind the baseplate at a distance is a pane of glass to enable the air in the space (9) to be evacuated through an outlet (8). USE/ADVANTAGE - Easily assembled and it presents no hindrance to the irradiation.

Cryogenic apparatus

A cryogenic apparatus comprises a helium dump 10 for providing a supply of helium-3 gas to a sorption pump 12. When the sorption pump 12 is out-gassed, helium-3 gas is condensed as liquid helium-3 by a condenser 14. The sorption pump can then pump on the liquid helium-3 to lower the temperature below 1K. A non-return valve 30 is arranged to admit helium-3 gas supplied from the helium dump to the sorption pump 12 and condenser 14, but to prevent return of helium-3 to the helium dump 10, so that when helium-3 is out-gassed from the sorption pump it is in a closed volume arranged so that the pressure of the helium-3 at the condenser can rise and exceed the pressure of the supply of helium-3. The pressure of He-3 in the condenser 14 may exceed 350 kPa and a pressure relief valve may open when the pressure reaches 700 kPa.

When a defrosting of an exterior heat exchanger is performed, a refrigeration cycle device switches to a refrigerant circuit, in which a refrigerant discharged from a compressor dissipates its heat at an interior condenser and the exterior heat exchanger, the refrigerant dissipating the heat at the interior condenser and the exterior heat exchanger is decompressed by a battery expansion valve, and then the refrigerant decompressed by the battery expansion valve evaporates at a battery heat exchanger to be drawn into the compressor. Thus, the heat absorbed by the refrigerant from a secondary battery via a battery ventilation air can be used to defrost the exterior heat exchanger, while sufficiently heating the interior ventilation air at the interior condenser.
