A first compressor is supported by the intermediate plate through a plurality of first elastic members. A second compressor is supported by the same intermediate plate through a plurality of first elastic members.

Abstract: A refrigeration apparatus includes a refrigerant circuit switchable between a first operation of performing a refrigeration cycle in which a first compressor is stopped and a second compressor is driven and a second operation of performing a refrigeration cycle in which the first and second compressors and are driven. The refrigeration apparatus further includes a reduction mechanism configured to reduce a refrigerant flowing into the first compressor while a first condition is satisfied during the first operation. The first condition indicates that an internal pressure of the first compressor is lower than an evaporation pressure of an evaporator.

The first compressor and the second compressor are supported by the first intermediate plate and the second intermediate plate, respectively, through a plurality of first elastic members.

Abstract: In an air-conditioning system including a thermal storage heat exchanger, a refrigerant circuit is configured such that an indoor heat exchanger and a receiver communicate with the thermal storage heat exchanger when an operational mode of the refrigerant circuit is switched to a cooling operation in which the thermal storage heat exchanger serves as a radiator and the indoor heat exchanger serves as an evaporator.

Abstract: An air-conditioning system includes a refrigerant circuit configured to perform a refrigeration cycle. The refrigerant circuit connects a compressor, a utilization-side heat exchanger that performs air conditioning of an indoor space, and a thermal storage heat exchanger. The air-conditioning system executes a first operation in accordance with a reduction command to reduce commercial power consumption in a whole of the air-conditioning system. The first operation allows the utilization-side heat exchanger to perform air conditioning using the thermal storage heat exchanger as a heat source. The air-conditioning system includes a power reduction section configured to perform a first control in synchronization with timing of a start of the first operation. The first control makes the commercial power consumption in the whole of the air-conditioning system equal to or lower than a first value.

Abstract: A gear device includes a gear, a pin, a plate member, a retainer portion, a contact part and a non-contact part. The pin is inserted into an opening of the gear. The plate member is disposed on a face of the gear and attached along an outer peripheral surface of the pin. The retainer portion is disposed in a vicinity of an end portion of the pin, with the plate member being interposed between the retainer portion and the face of the gear. The contact part is formed by faced surfaces of the retainer portion and the plate member with parts of the faced surfaces annularly making contact in a position closest to an outer peripheral surface of the pin. The non-contact part is formed by the faced surfaces with parts of the faced surfaces not making contact in a position away from the outer peripheral surface of the pin.

Abstract: A gas purifying device has a re-circulating section configured to re-circulate liquid discharged from an element positioned on a downstream side of an airflow to reflow to a liquid circulation system path of an element positioned on an upstream side of the air flow. The liquid dissolves and removes low-concentration contaminants by gas-liquid contact. The liquid is discharged from the element on the downstream side and is made to reflow to the element on the upstream side through the re-circulating section. Contaminants are dissolved and removed by gas-liquid contact between the liquid and non-purified air containing high-concentration contaminants.

Abstract: A gas purifier includes an air passage. An adsorption removal device, which includes a regenerable adsorbent for adsorbing chemical contaminants from non-purified air and separating the adsorbed contaminants through a regeneration process, and a gas purification unit, which performs gas-liquid contact with a porous film to separate and removes contaminants from the non-purified air into a liquid, are arranged in an air passage. The chemical contaminants are adsorbed and removed by the adsorption removal device.

Abstract: The part-mounting structure of the present invention includes a part-mounting portion of a sandwich structure constituted by a core layer and plastic skin layers formed on both surfaces of the core layer, and a part-mounting metal member, at least one of the skin layers having a tapered recess having a sloped side wall and a flat bottom wall, the bottom wall being constituted by the skin layers bonded together, the part-mounting metal member having a bottom plate, and a pair of side plates vertically extending from the bottom plate substantially on both sides, at least one of the side plates having a dent tapered complementarily to the tapered recess of the sandwich structure. The part-mounting metal member is mounted to the part-mounting portion of the sandwich structure with a surface of the tapered recess of the sandwich structure and a surface of the tapered dent of the part-mounting metal member bonded together by an adhesive.
