Patent JP-H0848141-A (JP)
Title: Refrigeration unit for air-conditioner vehicle
Inventor: YAMANAKA YASUSHI
IPC: B60H1/32
Filed: 1994-08-05
Abstract: PURPOSE:To reconcile the secureness of frost resistance in an evaporator and the improvement of antifogging effect in a windowpane. CONSTITUTION:At the time of low outside temperature in the winter, a degree of dryness in a gas-liquid two-phase coolant at the downstream side of an expansion valve 5 comes to smallness, and thereby a partial liquid coolant flows out at the side of a gas coolant outflow passage 9 of a gas-liquid separator 7, putting the liquid coolant back to a compressor 1. Accordingly, pressure is made hard to be yet lower in time of starting this compressor 1 by means of on-off control, so frost is hard to be produced in an evaporator 6. On the other hand, outside air temperature is detected by an outside air temperature sensor 13, and at the time of low outside air temperature (for example, when it is lower than 10 deg.C), the setting temperature to the detected temperature of an evapoarator temperature sensor 14 is altered to the low temperature side at a control unit 15, and an evaporator temperature is lowered to sane extent. With this constitution, an antifogging effect in time of a winter inside air mode is thus improved.

Title: Metal hydride container
Inventor: KUROOKA MASAYUKI
IPC: F17C11/00
Filed: 1985-08-26
Abstract: PURPOSE:To make it possible to absorb an excessive stress due to expansion of metal hydride, by separately storing the metal hydride by means of plural stages of hydrogen filters in a pressure container. CONSTITUTION:Hydrogen induced from a hydrogen inlet 1 is allowed to pass through hydrogen filters 7, and is absorbed by a metal hydride 9. Heat generated at this time is transmitted to a heat medium pipe 8, and is applied to a heat medium. Then, the heat is taken out of the system, and is utilized. At this time, the metal hydride 9 absorbs the hydrogen to be expanded. However, as the metal hydride 9 is stored in plural areas separated by plural stages of the hydrogen filters in a container 2, the pressure due to the weight of particles of the metal hydride 9 is small, and the stress due to expansion is not almost applied to a cylinder 6 and the heat medium pipe 8 since the expansion acts to move the particles upwardly.
