Definitions

  • the refrigerant amount in the refrigeration device is reduced since the capacity of the outdoor heat exchanger is less than or equal to the capacity of the indoor heat exchanger. Although the excess refrigerant is produced in this refrigeration device during the cooling operation, damage to the refrigerant control is prevented since the excess refrigerant is contained in the refrigerant storage tank.
  • the liquid refrigerant in the refrigerant storage tank 25 is depressurized to a low pressure in the refrigeration cycle by the expansion mechanism 24, and then is conveyed through the liquid-side shutoff valve 27 and the liquid refrigerant communication pipe 5 to the indoor heat exchanger 41.
  • the refrigerant storage tank 25 primarily includes a cylindrical container 251, a first connection pipe 252, a second connection pipe 253 and a third connection pipe 254.
