Refrigeration device

Abstract

Frame parts are arranged in a row, and in each of which a compressor, an air heat exchanger, a receiver, and a system-side electric component box corresponding to each other are installed as a single unit.

1 . A refrigeration apparatus comprising:
 a plurality of refrigerant circuits to each of which a compressor, an air heat exchanger and a receiver are connected;   a plurality of system-side electric component boxes each having an electric component corresponding to an associated one of the compressors; and   a support having a plurality of support parts arranged in a row, wherein   the compressor, the air heat exchanger, the receiver, and the system-side electric component box corresponding to each other are installed as a single unit in each of the support parts.   
     
     
         2 . The refrigeration apparatus of  claim 1 , further comprising:
 a water circuit to which a water heat exchanger allowing a refrigerant and water to exchange heat, and a water pump transporting water are connected; and   an operation-side electric component box containing an operation unit, wherein   the plurality of support parts includes a first end support part and a second end support part,   the operation-side electric component box containing the operation unit is installed in the first end support part, and   the water pump is installed in the second end support part.   
     
     
         3 . The refrigeration apparatus of  claim 2 , wherein the plurality of support parts include at least one intermediate support part arranged between the first end support part and the second end support part. 
     
     
         4 . The refrigeration apparatus of  claim 2 , wherein
 in the second end support part, the system-side electric component box,   the compressor, and the water pump are arranged in this order from the first end support part toward the second end support part.   
     
     
         5 . The refrigeration apparatus of  claim 3 , wherein
 in at least one of the intermediate support parts, the system-side electric component box, the compressor, and the water heat exchanger are arranged in this order from the first end support part toward the second end support part.   
     
     
         6 . The refrigeration apparatus of  claim 1 , wherein
 a maintenance port is formed in at least one of side surfaces of the support extending in a direction in which the support parts are arranged, and   the compressor is arranged closer to the maintenance port than the receiver in at least one of the plurality of support parts.   
     
     
         7 . The refrigeration apparatus of  claim 6 , wherein the system-side electric component box is arranged closer to the maintenance port than the receiver in at least one of the plurality of support parts. 
     
     
         8 . The refrigeration apparatus of  claim 6 , wherein
 a withdrawable bottom plate on which the compressor is placed is provided at a bottom of each of the plurality of support parts, the withdrawable bottom plate being withdrawable toward the maintenance port.   
     
     
         9 . The refrigeration apparatus of  claim 1 , wherein
 the single unit installed in each of the support parts includes a refrigerant cooling unit which is connected to the refrigerant circuit and cools the electric component in the corresponding system-side electric component box with a refrigerant.
