Unit cooler

Abstract

To provide a unit cooler capable of supplying cool air to the outside of a housing while saving electric power and securing sufficient refrigeration capacity.SOLUTION: In a unit cooler 1 according to this invention, a motor compressor 301 has a discharge housing 301a for compressing and discharging refrigerant, and the discharge housing 301a is arranged closer to an inlet port 13a than other parts of the motor compressor 301. At least one of a first pipe 307a connecting the discharge housing 301a and a condenser 302, and a second pipe 307b connecting the condenser 302 and a decompression device 303, out of the pipe 307, is provided in a flow path F1 where outside air taken out of the inlet port 13a to a first fan 308 flows.SELECTED DRAWING: Figure 4

Claims

1. Housing and The housing comprises an air conditioning unit housed within the housing, which constitutes a refrigeration cycle and cools the air to supply it to the outside of the housing, The air conditioning unit comprises an electric compressor, a condenser, a pressure reducing device, an evaporator, piping for circulating refrigerant, a first fan for supplying air to the condenser, and a second fan for supplying air to the evaporator. The housing has an intake port for drawing outside air into the housing by the first fan, and a heat exhaust port for discharging heat from the condenser to the outside of the housing by airflow from the first fan. The electric compressor has a discharge housing for compressing and discharging the refrigerant, and the discharge housing is positioned closer to the intake port than other parts of the electric compressor. A unit cooler characterized in that, of the aforementioned piping, at least one of the first piping connecting the discharge housing and the condenser, and the second piping connecting the condenser and the pressure reducing device, is provided in a flow path through which outside air taken in from the intake port toward the first fan flows.

2. The unit cooler according to claim 1, wherein at least one of the first pipe and the second pipe has a bent portion in the flow path through which outside air taken in from the intake port toward the first fan flows.

3. The unit cooler according to claim 1, wherein the discharge housing guides outside air taken in from the intake port toward the first fan toward at least one of the first pipe and the second pipe, and defines a flow path through which the outside air taken in from the intake port toward the first fan flows.

4. The first piping has a protruding portion that extends upward from the discharge housing and a bent portion that bends toward the condenser from the protruding portion. The unit cooler according to claim 2, wherein the protruding portion and the bent portion are arranged in a flow path through which outside air taken in from the intake port toward the first fan flows.

5. The electric compressor has an inverter housing that protrudes above the discharge housing and contains an inverter that controls the motor built into the electric compressor. The unit cooler according to claim 4, wherein the inverter housing partitions a flow path through which outside air taken in from the intake port toward the first fan flows.
