    摘要: A solar collector comprising a heat collecting panel for receiving the sunlight, a cover glass arranged above the panel, and a sunlight-pervious diaphragm disposed between the panel and cover glass to form a closed space between itself and the cover glass, the diaphragm being adapted to expand and contract to vary the volume of the closed space, whereby the pressure in the closed space is kept substantially equal to the atmospheric pressure. With this arrangement, since the collector does not permit the entry of humid ambient air into the closed space, no condensates will be produced on the inner surface of the cover glass. Further, if the diaphragm is adapted to sag and contact the panel due to its expansion at the time of abnormal heating, heat dissipation from the panel is accelerated. Thus damage to the panel due to overheating can be prevented.

    摘要: The structure is arranged in such a manner that nonazeotropic mixed refrigerant is enclosed therein and a fractioning/separating device is disposed in a low pressure circuit in the main circuit of refrigerating cycle so as to conduct separation operation, the fraction/separation can be conducted at a low pressure in a separation mode, the specific volume of refrigerant gas generated in a reservoir due to heat supplied from a heater is enlarged, and the velocity of gas which moves upwards in the fractioning/separating device can be increased, causing a gas-liquid contact to be promoted. As a result, high performance separation can be conducted at reduced quantity of heat, causing the density of high boiling point refrigerant reserved to be significantly raised. Thus, the composition in the main circuit becomes a composition enriched with low boiling point refrigerant exhibiting excellent heating performance so as to satisfactorily cope with an increase in the load.
