Abstract: A compressor includes a housing member having an injection passage communicating with a compression chamber, a check valve in the injection passage, and an injection pipe that supplies refrigerant to the injection passage. The check valve has a slidable valve body, and a valve supporting member that restricts movement of the valve body toward the injection pipe side when the check valve checks a flow of refrigerant. A center hole is formed in the valve body. A peripheral hole is formed in the valve supporting member and opposes a rim part of the valve body. Refrigerant passes through the peripheral and center holes and is supplied to the compression chamber. The center hole can be closed by the valve supporting member, and the peripheral hole can be closed by the rim part of the valve body when the check valve checks the flow of refrigerant.

Abstract: A filter medium includes first and second porous films mainly containing fluororesin, and a pre-collection member upstream of the first film. The second film is downstream of the first film. The pre-collection member has a pressure drop when air is passed through at a flow rate of 5.3 cm/s of between 15 Pa and 55 Pa, a collection efficiency of NaCl particles having a particle diameter of 0.3 μm when air containing the particles is passed hrough at a flow rate of 5.3 cm/s of between 25% and 80%, a thickness of 0.4 mm or less, and a PF value between 7 and 15. The PF value={−log((100−collection efficiency (%))/100)}/(pressure drop (Pa)/1000). A ratio of the PF value of the pre-collection member to the PF value when the first and second films are overlapped, is between 0.20 and 0.45. The filter medium can be used in a filter pack or filter unit, and may be produced by integrating the first and second films and the pre-collection member using heat lamination.

Abstract: A control apparatus controls a facility device and is used in an energy consumption management system that grants an incentive to a user of the facility device when the facility device performs an adjustment of energy consumption for an adjustment period in response to an adjustment request. The control apparatus includes an incentive standard setting unit, a comfort standard setting unit, an incentive prediction calculation unit, a comfort prediction calculation unit, a control condition change unit, and a control unit. The control condition change unit determines whether incentive and comfort predictions are within ranges of incentive and comfort standards, and changes a preset control condition when there is variation in a derivation element of the incentive during the adjustment period. The control unit controls the facility device based on the control condition changed by the control condition change unit after the variation has occurred in the derivation element. A control apparatus controls a facility device and is used in an energy consumption management system that grants an incentive to a user of the facility device when the facility device performs an adjustment of energy consumption for an adjustment period in response to an ...more ...less

Abstract: A control device estimates a flow rate and an effective height difference of a fluid machine based on a characteristic detectable with regard to a rotating electrical machine and correlating with the flow rate and the effective height difference of the fluid machine. A total flow rate in a pipe system is estimated based on these values estimated by the control device and a flow resistance characteristic line, and cooperative control of the fluid machine and the flow rate control valve is performed such that the estimated value of the total flow rate becomes close to a target flow rate of the total flow rate in the pipe system. A control device estimates a flow rate and an effective height difference of a fluid machine based on a characteristic detectable with regard to a rotating electrical machine and correlating with the flow rate and the effective height difference of the fluid machine.
