摘要： An air conditioner 1 is disclosed as an air conditioner configured to condition air by connecting an indoor unit 2 including a first heat exchanger 11 in which a refrigerant exchanging heat with room air flows to an outdoor unit 3 including a second heat exchanger 24 in which a refrigerant exchanging heat with outdoor air flows. The first heat exchanger 11 includes a first heat transfer tube 11a1 made of aluminum or aluminum alloy, and the second heat exchanger 24 includes a second heat transfer tube 24a made of aluminum or aluminum alloy. A first sacrificial layer 45a is formed on an outer circumferential surface of the first heat transfer tube 11a1, and a second sacrificial layer 35 is formed on an outer circumferential surface of the second heat transfer tube 24a. The maximum thickness to of the second sacrificial layer 35 is larger than the sacrificial layer ti1 of the first sacrificial layer 45a. This suppresses corrosion of the heat transfer tube of the outdoor unit.

摘要： A split air conditioner has a cabinet with a fan and evaporator for mounting within a structure. The cabinet includes a filter or a stacked filter system positioned in the flow path between an air inlet and an air outlet for filtering contaminants from the air. Movable dampers are provided for selectively changing the airflow path to selectively bypass the filter to provide a greater or lesser degree of filtration of the air. Preferably, the filter is a high performance HEPA-like filter having substantially less pressure drop.

摘要： In one embodiment of the present disclosure, a heating, ventilating, and air conditioning (HVAC) system includes a refrigerant circuit configured to flow a refrigerant. The refrigerant circuit includes a compressor configured to compress the refrigerant, a condenser configured to receive the refrigerant from the compressor and to condense the refrigerant, a valve configured to receive a first portion of the refrigerant from the condenser and to decrease a pressure of the first portion of the refrigerant, and an evaporator configured to receive the first portion of the refrigerant from the condenser and configured to evaporate the first portion of the refrigerant. The refrigerant circuit also includes a refrigerant sub-circuit configured to receive a second portion of the refrigerant from the condenser and to convert thermal energy of the second portion of the refrigerant to electrical energy.

摘要： A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.

摘要： An evaporator rough-in box includes a plurality of walls that define and enclose a chamber, a first one of the walls having cutting lines that encircle a faceplate, one of the cutting lines defining an integral hinge that maintains the faceplate attached to the first one of the walls when a remainder of the cutting lines are cut so that the faceplate can move between an open position and a closed position. A closure maintains the faceplate in the closed position by attaching an edge of the faceplate to the first one of the walls. In addition, ports are provided in at least one of the walls, and a drainage sump is provided at a vertically lower end of the rough-in box, the drainage sump having a drain outlet.
