摘要： PROBLEM TO BE SOLVED: To secure operation stability of an auxiliary compressor integrated expander configured to not have a driving source such as a motor to be mounted in a refrigerating/air-conditioning device using carbon dioxide as a coolant.
SOLUTION: The refrigerating/air-conditioning device includes an auxiliary compressor connected to a coolant delivery side of a main compressor, a radiator connected to a delivery side of the auxiliary compressor and sending cooled coolant to the expander, and an evaporator connected to a coolant delivery side of the expander and sending the coolant to the main compressor. The scroll expander is composed by connecting the auxiliary compressor and the expander by a drive shaft and housing them in an airtight container, and an oil passage adjusting valve is provided in an oil passage connecting an oil reservoir part provided in a lower part of the airtight container and a coolant inlet of the expander. By this, by using pressure loss of the radiator, a leakage gap of the expander is sealed by oil, recovery expansion power is increased by reduction of leakage loss, and operation stability is secured.

摘要： PROBLEM TO BE SOLVED: To prevent the flow rate of liquid refrigerant which is discharged from an accumulator from being excessively large and maintain the necessary quantity of refrigerating machine oil in a compressor by reducing the quantity of refrigerating machine oil stored in the accumulator. SOLUTION: An accumulator introduces liquid and gas as a fluid which circulates in a refrigerating air conditioning circuit into a first space 1 by an inlet means 3, and discharges gas refrigerant to the refrigerating air conditioning circuit via a gas flow means 4, a second space 2 and an outlet means 5. Liquid level height holding means 7 and 8 prevent the height of liquid introduced and retained in the first space 1 from reaching a prescribed height or higher. When the height of liquid reaches the prescribed height, the liquid in the first space is moved to the second space 2 from the first space 1. Further, refrigerating machine oil retained in the first space 1 is supplied to the refrigerating air conditioning circuit by a return means 6.

摘要： PROBLEM TO BE SOLVED: To prevent incomplete lubrication and prevent the breakdown of a compressor by providing an accumulator with first and second oil recovery pipes which are retained within a sealed container and besides have a plurality of oil recovery holes in vertical direction, and a communication port which connects the bottom of the oil recovery pipe with a discharge pipe. SOLUTION: To a discharge pipe 12, two pieces of an auxiliary pipe 14a of high liquid level and an auxiliary pipe 14b for low liquid level being, for example, oil recovery pipes provided with plural oil recovery holes 10 and located in different positions in a vertical direction are attached, and further a communication port is made. Then, a wet refrigerant flows in the tubular sealed container 13 from a suction pipe 11, and a liquid refrigerant and lubricant is collected. In the case that the lubricant having a low solubility to the refrigerant and a smaller specific gravity than the liquid refrigerant separates from the liquid and floats, or in the case that a lubricant- rich layer at an upper layer, and a liquid-refrigerant-rich layer, at a lower layer, are collected at the time of low temperature even in the case of a high solubility oil, the breakdown of a compressor can be prevented by recovering the floating oil from the oil recovery holes 10a of the auxiliary pipes 14a and 14b for high and low liquid levels.
