Abstract
An ejector is used in place of a compressor with moving parts in the refrigeration apparatus. The ejector has an intake side connected to the gas space of a liquefied gas tank, a propellant jet input connected to a delivery side of the compressor to receive a high pressure flow of gas and a delivery side in the form of a diffusor output connected to the intake side of the compressor. A pair of ejectors can be connected in series or, where more than two liquefied gas tanks are used, in parallel.
Claims8
Apparatus for a refrigeration circuit comprising
- a compressor for compressing a gas, said compressor having an intake side for receiving gas and a delivery side for expelling compressed gas;
- an after-cooler downstream of said compressor for cooling the compressed gas;
- cooling means downstream of said after-cooler for at least partially liquefying the compressed gas;
- a pair of tanks connected in series to said cooling means to receive the at least partially liquefied compressed gas, a first one of said tanks having a gas space connected to said intake of said compressor to recycle gas thereto;
- and
- an ejector having an intake side connected to a gas space of the other of said tanks to receive gas therefrom, a propellant jet input connected to said delivery side of said compressor and a delivery side connected to said intake side of said compressor.
