  • Patent number: 8844301
    Abstract: An air-conditioning apparatus includes a heat medium relay unit accommodating heat exchangers for exchanging heat between a flammable refrigerant and a heat medium different from the refrigerant. The heat medium relay unit is disposed in a space in a structure that is not an air conditioned space. One or more outdoor units are connected to the heat medium relay unit to circulate the refrigerant therein. The outdoor units are disposed in a space outside the structure or a space inside the structure that is not isolated completely from the space outside the structure. One or more indoor units are connected to the heat medium relay unit by a different system than that of the outdoor units. The indoor units circulate the heat medium therein to exchange heat with air related to the indoor space.

  • Publication number: 20140245608
    Abstract: In removal processing using a pulsed laser beam, processing deviation occurs in the depthwise direction to cause a processing error in a predetermined removal shape. A first pulsed laser beam L1 is a pulsed laser beam having a wavelength that exhibits transmittance to a workpiece 6, and a second pulsed laser beam L2 is a pulsed laser beam having a wavelength that exhibits absorption to the workpiece 6. The first pulsed laser beam L1 is focused into the workpiece 6, and a focal point P1 of the first pulsed laser beam L1 is scanned along the outline of a predetermined removal region R1 to form a modified portion 6A along the outline of the predetermined removal region R1. Next, removal processing is performed by scanning the second pulsed laser beam L2 in a region enclosed by the modified portion 6A.

  • Patent number: 8616017
    Abstract: A first cycle, in which a first medium is circulated, employs a compressor, a first heat exchanger structured with an air heat exchanger, a second heat exchanger, and a third heat exchanger. A second cycle, in which a second medium is circulated and heat is exchanged with the first medium through the second heat exchanger, employs indoor units, each having a fan. A third cycle, in which the second medium is circulated and heat is exchanged with the first medium through the third heat exchanger, shares the indoor units with the second cycle. Flow path switching valves switch flow paths between the second cycle and third cycle. Before the first heat exchanger is defrosted, a halted indoor unit is filled with the second medium in the third cycle with its fan being halted. The third heat exchanger functions as an evaporator during a defrosting operation.
