A refrigerant circuit in an air conditioner comprises a compressor that compresses a refrigerant, a condenser that liquefies the refrigerant, a pressure reducing device that reduces the pressure of the compressed refrigerant, and an evaporator that exchanges heat by utilizing the refrigerant and generates an air-conditioning air. The condenser comprises plural fin tubes, through which the refrigerant passes, two headers, to which both ends of the fin tubes are connected and which has a firm structure, upper and lower mounting brackets that are fixed to the headers, and vibration insulating materials that collaborate with pin members and support the condenser via the upper and lower mounting brackets. The valve unit is fixed to the header or to the upper or lower mounting bracket.

1. An air conditioner, comprising a refrigerant circuit in which components are connected by pipes through which a refrigerant passes and which forms a closed piping circuit:wherein the refrigerant circuit comprising a compressor that compresses the refrigerant and a condenser that is contiguous to the compressor on the downstream side thereof, is connected to the compressor by a pipe, and cools and liquefies the compressed refrigerant, wherein the condenser comprises plural fin tubes, through which the refrigerant compressed by the compressor passes and which serve as a heat-exchanging portion, two headers, to which both ends of the plural fin tubes are connected respectively and fluidly and which have a firm structure, at least one vibration insulating material that supports the condenser and has a vibration insulating effect, and at least one lower mounting bracket that is firmly fixed to at least one of the two headers, on the bottom face of which the vibration insulating material is provided, and though which the vibration insulating material joins the condenser, wherein the refrigerant circuit further comprises a pressure reducing device that is contiguous to the condenser on the downstream side thereof, is connected to the condenser by a pipe, and reduces the pressure of the compressed refrigerant and expands it, at least one evaporator that is contiguously located on the downstream side of the pressure reducing device, is connected to the pressure reducing device by a pipe, through which the refrigerant passes and has an air blower, wherein the evaporator is contained in an air-conditioning duct and air is supplied to the air-conditioning duct by the air blower, therefore, the air passes through the at-least-one evaporator and is cooled or heated, a bypass pipe, through which the refrigerant bypasses the condenser and the pressure reducing device and flows through the evaporator, and a channel switching means that has a function to change the flow routes of the refrigerant, from the compressor, between the condenser and the bypass pipe and is integrally formed with plural components into a unit; and wherein the channel switching means is attached to the lower mounting bracket. 2. An air conditioner, as set forth in claim 1, wherein the condenser comprisesat least one upper mounting bracket that is aligned to the at-least-one lower mounting bracket in the vertical direction, is firmly fixed to at least one of the headers, and assists the installation of the condenser, and at least one pin member that is aligned to the at-least-one vibration insulating material in the vertical direction, presses down the condenser via the upper mounting bracket, and collaborates with the vibration insulating material in enabling the support of the condenser. 3. An air conditioner, as set forth in claim 1, wherein the channel switching means is attached to the upper or lower mounting bracket, which is a firm structure of the condenser.4. An air conditioner, as set forth in claim 1, wherein the channel switching means comprises at least two parts among:a first switching valve provided between the compressor and the condenser; at least part of the bypass pipe connected to the pipe communicating the pressure reducing device with the evaporator; a second switching valve &ranged within the bypass pipe; a throttle arranged within the bypass pipe; and a check valve arranged on the upstream side of the connecting part where the bypass pipe is connected to the pipe communicating the pressure reducing device with the evaporator. 5. An air conditioner, as set forth in claim 3, wherein the first and/or second switching valves are electromagnetic valves.
